The name of the JV was Inner Mongolia Erdos TCH Energy Saving Development Co., Ltd. (“Erdos TCH”) with a term of 20 years. Erdos contributed 7% of the total investment of the project, and Xi’an TCH Energy Technology Co., Ltd. (“Xi’an TCH”) contributed 93%. On June 15, 2013, Xi’an TCH and Erdos entered into a share transfer agreement, pursuant to which Erdos sold its 7% ownership interest in the JV to Xi’an TCH for $1.29 million (RMB 8 million), plus certain accumulated profits. Xi’an TCH paid the $1.29 million in July 2013 and, as a result, became the sole stockholder of the JV. Erdos TCH currently has two power generation systems in Phase I with a total of 18 MW power capacity, and three power generation systems in Phase II with a total of 27 MW power capacity. On April 28, 2016, Erdos TCH and Erdos entered into a supplemental agreement, effective May 1, 2016, whereby Erdos TCH cancelled monthly minimum lease payments from Erdos, and started to charge Erdos based on actual electricity sold at RMB 0.30 / KWH. The selling price of each KWH is determined annually based on prevailing market conditions. Since May 2019, Erdos TCH has ceased its operations due to renovations and furnace safety upgrades of Erdos, and the Company initially expected the resumption of operations in July 2020, but the resumption of operations was further delayed due to government’s mandate for Erdos to significantly lower its energy consumption per unit of GDP. Erdos and the municipal government are currently under discussion for seeking the solution of achieving the energy saving target. During this period, Erdos will compensate Erdos TCH RMB 1 million ($145,460) per month, until operations resume. The Company has not recognized any income due to the uncertainty of collection. In addition, Erdos TCH has 30% ownership in DaTangShiDai (BinZhou) Energy Savings Technology Co., Ltd. (“BinZhou Energy Savings”), 30% ownership in DaTangShiDai DaTong Recycling Energy Technology Co., Ltd. (“DaTong Recycling Energy”), and 40% ownership in DaTang ShiDai TianYu XuZhou Recycling Energy Technology Co, Ltd. (“TianYu XuZhou Recycling Energy”). These companies were incorporated in 2012 but there have not been any operations since then nor has any registered capital contribution been made.

As of September 30, 2019, Xi’an Hanneng already owned 29,948,000 shares of Huaxin, but was not able to obtain the remaining 17,202,000 shares due to halted trading of Huaxin stock by NEEQ for not filing its 2018 annual report. On December 20, 2019, Mr. Bai and all the related parties agreed to have Mr. Bai instead making a payment in cash for the transfer price of Huayu (see Note 9 for detail). On January 10, 2020, Zhonghong, Tianyu and Huaxin signed a transfer agreement to transfer all assets under construction and related rights and interests of Xuzhou Tian’an Project to Tianyu for RMB 170 million including VAT ($24.37 million) in three installment payments. The 1st installment payment of RMB 50 million ($7.17 million) to be paid within 20 working days after the contract is signed. The 2nd installment payment of RMB 50 million ($7.34 million) is to be paid within 20 working days after completion of the project construction but no later than July 31, 2020. The final installment payment of RMB 70 million ($10.28 million) is to be paid before December 31, 2020. The Company received the payment in full for Tian’an Project as of December 31, 2020. Zhongtai Waste Heat Power Generation Energy Management Cooperative Agreement On December 6, 2013, Xi’an TCH entered into a CDQ and WHPG Energy Management Cooperative Agreement (the “Zhongtai Agreement”) with Xuzhou Zhongtai Energy Technology Co., Ltd. (“Zhongtai”), a limited liability company incorporated in Jiangsu Province, China. Pursuant to the Zhongtai Agreement, Xi’an TCH was to design, build and maintain a 150 ton per hour CDQ system and a 25 MW CDQ WHPG system and sell the power to Zhongtai, and Xi’an TCH is also to build a furnace to generate steam from the smoke pipeline’s waste heat and sell the steam to Zhongtai. In March 2016, Xi’an TCH entered into a Transfer Agreement of CDQ and a CDQ WHPG system with Zhongtai and Xi’an Huaxin (the “Transfer Agreement”). Under the Transfer Agreement, Xi’an TCH agreed to transfer to Zhongtai all of the assets associated with the CDQ Waste Heat Power Generation Project (the “Project”), which is under construction pursuant to the Zhongtai Agreement. Additionally, Xi’an TCH agreed to transfer to Zhongtai the Engineering, Procurement and Construction (“EPC”) Contract for the CDQ Waste Heat Power Generation Project which Xi’an TCH had entered into with Xi’an Huaxin in connection with the Project. Xi’an Huaxin will continue to construct and complete the Project and Xi’an TCH agreed to transfer all its rights and obligations under the EPC Contract to Zhongtai. As consideration for the transfer of the Project, Zhongtai agreed to pay to Xi’an TCH RMB 167,360,000 ($25.77 million) including (i) RMB 152,360,000 ($23.46 million) for the construction of the Project; and (ii) RMB 15,000,000 ($2.31 million) as payment for partial loan interest accrued during the construction period. Those amounts have been, or will be, paid by Zhongtai to Xi’an TCH according to the following schedule: (a) RMB 50,000,000 ($7.70 million) was to be paid within 20 business days after the Transfer Agreement was signed; (b) RMB 30,000,000 ($4.32 million) was to be paid within 20 business days after the Project was completed, but no later than July 30, 2016; and (c) RMB 87,360,000 ($13.45 million) was to be paid no later than July 30, 2017. Xuzhou Taifa Special Steel Technology Co., Ltd. (“Xuzhou Taifa”) guaranteed the payments from Zhongtai to Xi’an TCH. The ownership of the Project was conditionally transferred to Zhongtai following the initial payment of RMB 50,000,000 ($7.70 million) by Zhongtai to Xi’an TCH and the full ownership of the Project will be officially transferred to Zhongtai after it completes all payments pursuant to the Transfer Agreement. The Company recorded a $2.82 million loss from this transaction in 2016. In 2016, Xi’an TCH had received the first payment of $7.70 million and the second payment of $4.32 million. However, the Company received a repayment commitment letter from Zhongtai on February 23, 2018, in which Zhongtai committed to pay the remaining payment of RMB 87,360,000 ($13.45 million) no later than the end of July 2018; in July 2018, Zhongtai and the Company reached a further oral agreement to extend the repayment term of RMB 87,360,000 ($13.45 million) by another two to three months. In January 2020, Zhongtai paid RMB 10 million ($1.41 million); in March 2020, Zhongtai paid RMB 20 million ($2.82 million); in June 2020, Zhongtai paid RMB 10 million ($1.41 million); and in December 2020, Zhongtai paid RMB 30 million ($4.28 million), which was payment in full. Accordingly, the Company reversed the bad debt expense of $5.80 million which had been recorded earlier. Formation of Zhongxun On March 24, 2014, Xi’an TCH incorporated a subsidiary, Zhongxun Energy Investment (Beijing) Co., Ltd. (“Zhongxun”) with registered capital of $5,695,502 (RMB 35,000,000), which must be contributed before October 1, 2028. Zhongxun is 100% owned by Xi’an TCH and will be mainly engaged in project investment, investment management, economic information consulting, and technical services. Zhongxun has not yet commenced operations nor has any capital contribution been made as of the date of this report. Formation of Yinghua On February 11, 2015, the Company incorporated a subsidiary, Shanghai Yinghua Financial Leasing Co., Ltd. (“Yinghua”) with registered capital of $30,000,000, to be paid within 10 years from the date the business license is issued. Yinghua is 100% owned by the Company and will be mainly engaged in financial leasing, purchase of financial leasing assets, disposal and repair of financial leasing assets, consulting and ensuring of financial leasing transactions, and related factoring business. Yinghua has not yet commenced operations nor has any capital contribution been made as of the date of this report. Reverse Stock Split On April 13, 2020, the Company filed a certificate of change (“Certificate of Change”) with the Secretary of State of the State of Nevada, pursuant to which, on April 13, 2020, the Company effected a reverse stock split of its Common Stock, at a rate of 1-for-10, accompanied by a corresponding decrease in the Company’s issued and outstanding shares of Common Stock (the “Reverse Stock Split”). The accompanying consolidated financial statements and related disclosure in for periods prior to the Reverse Stock Split have been retroactively restated to reflect this reverse stock split. Other Events In December 2019, a novel strain of coronavirus (COVID-19) was reported in and the World Health Organization has declared the outbreak to constitute a “Public Health Emergency of International Concern.” This pandemic, which continues to spread to additional countries, and is disrupting supply chains and affecting production and sales across a range of industries as a result of quarantines, facility closures, and travel and logistics restrictions in connection with the outbreak. However, as a result of PRC government’s effort on disease control, most cities in China were reopened, the outbreak in China is under the control. The Company disposed all of its systems and currently holds only five power generating systems through Erdos TCH, the Company initially expected to resume production of these five power generating systems in July 2020 from the renovation and furnace safety upgrade, but the resumption of operations was further delayed due to government’s request for Erdos’ production line rectification for lowering its energy consumption per unit of GDP; the Company expects the resumption date to be July 2021. As of this report date, there are some new Covid-19 cases discovered in a few provinces of China, however, the number of new cases is not significant due to PRC government’s strict control. On December 22, 2020, Shanghai TCH entered into an Equity Acquisition Agreement with Xi’an Taiying Energy Saving Technology Co., Ltd., a PRC company (“Xi’an Taiying”) and its three shareholders to purchase all of the issued and outstanding shares of stock of Xi’an Taiying. The purchase price for said shares shall consist of (i) 619,525 shares of common stock at an issuance price of $4.37 per share, (ii) 60,000,000 shares of Series A convertible stock and (iii) a cash payment of RMB 1,617,867,026 (approximately $247 million at a conversion rate of 1:6.55). The shares shall be issued within 15 business days after approval by the Board of Directors and/or shareholders of the Company and Nasdaq approval and the cash shall be paid in three tranches – RMB 390 million (approximately $59.5 million) within 10 days after the agreement is executed, RMB 300 million (approximately $45.8 million) by March 31, 2021 and RMB 927,867,026 (approximately $141.7 million) within 10 days after the shares of Xi’an Taiying are registered to Buyer. As of the date of this report, the Company has not obtained and there is no assurance that the Company will be able to obtain necessary approval to proceed with the transaction. In addition, the Company is currently renegotiating the payment terms with the sellers for paying less shares but does not know when the renegotiation will be completed.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited financial information as of and for the nine and three months ended September 30, 2021 and 2020 has been prepared in accordance with accounting principles generally accepted in the U.S. for interim financial information and with the instructions to Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, such financial information includes all adjustments (consisting only of normal recurring adjustments, unless otherwise indicated) considered necessary for a fair presentation of our financial position at such date and the operating results and cash flows for such periods. Operating results for the nine and three months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the entire year or for any other subsequent interim period. The interim consolidated financial information should be read in conjunction with the Financial Statements and the notes thereto, included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, previously filed with the SEC on April 15, 2021. Basis of Consolidation The CFS include the accounts of CREG and its subsidiaries, Shanghai Yinghua Financial Leasing Co., Ltd. (“Yinghua”) and Sifang Holdings; Sifang Holdings’ wholly owned subsidiaries, Huahong New Energy Technology Co., Ltd. (“Huahong”) and Shanghai TCH Energy Tech Co., Ltd. (“Shanghai TCH”); Shanghai TCH’s wholly-owned subsidiary, Xi’an TCH Energy Tech Co., Ltd. (“Xi’an TCH”); and Xi’an TCH’s subsidiaries, 1) Erdos TCH Energy Saving Development Co., Ltd (“Erdos TCH”), 100% owned by Xi’an TCH, 2) Zhonghong, 90% owned by Xi’an TCH and 10% owned by Shanghai TCH, and 3) Zhongxun, 100% owned by Xi’an TCH. Substantially all the Company’s revenues are derived from the operations of Shanghai TCH and its subsidiaries, which represent substantially all the Company’s consolidated assets and liabilities as of September 30, 2021. However, there was no revenue for the Company for the nine and three months ended September 30, 2021. All significant inter-company accounts and transactions were eliminated in consolidation. Uses and Sources of Liquidity For the nine and three months ended September 30, 2021, the Company had a net income of $1.39 million and net loss $0.56 million. For the nine and three months ended September 30, 2020, the Company had net loss of $0.28 million and 0.67 million. The Company had an accumulated deficit of $41.66 million as of September 30, 2021. The Company disposed all of its systems and currently holds only five power generating systems through Erdos TCH, the five power generating systems are currently not producing any electricity. The Company is in the process of transforming and expanding into an energy storage integrated solution provider. The Company plans to pursue disciplined and targeted expansion strategies for market areas the Company currently does not serve. The Company actively seeks and explores opportunities to apply energy storage technologies to new industries or segments with high growth potential, including industrial and commercial complexes, large scale photovoltaic (PV) and wind power stations, remote islands without electricity, and smart energy cities with multi-energy supplies. The Company’s cash flow forecast indicate it will have sufficient cash to fund its operations for the next 12 months from the date of issuance of these financial statements. Use of Estimates In preparing these CFS in accordance with US GAAP, management makes estimates and assumptions that affect the reported amounts of assets and liabilities in the balance sheets as well as revenues and expenses during the period reported. Actual results may differ from these estimates. On an on-going basis, management evaluates their estimates, including those related to allowances for bad debt and inventory obsolescence, impairment loss on fixed assets and construction in progress, income taxes, and contingencies and litigation. Management bases their estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other resources. Revenue Recognition A) Sales-type Leasing and Related Revenue Recognition On January 1, 2019, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 842 using the modified retrospective transition approach by applying the new standard to all leases existing at the date of initial application. Results and disclosure requirements for reporting periods beginning after January 1, 2019 are presented under ASC Topic 842, while prior period amounts have not been adjusted and continue to be reported in accordance with our historical accounting under Topic 840. (See Operating lease below as relates to the Company as a lessee). The Company’s sales type lease contracts for revenue recognition fall under ASC 842. During the nine and three months ended September 30, 2021 and 2020, the Company did not sell any new power generating projects. The Company constructs and leases waste energy recycling power generating projects to its customers. The Company typically transfers legal ownership of the waste energy recycling power generating projects to its customers at the end of the lease. Prior to January 1, 2019, the investment in these projects was recorded as investment in sales-type leases in accordance with ASC Topic 840 , “Lease ,” The Company finances construction of waste energy recycling power generating projects. The sales and cost of sales are recognized at the inception of the lease, which is when the control is transferred to the lessee. The Company accounts for the transfer of control as a sales type lease in accordance with ASC 842-10-25-2. The underlying asset is derecognized, and revenue is recorded when collection of payments is probable. This is in accordance with the revenue recognition principle in ASC 606 - Revenue from contracts with customers. The investment in sales-type leases consists of the sum of the minimum lease payments receivable less unearned interest income and estimated executory cost. Minimum lease payments are part of the lease agreement between the Company (as the lessor) and the customer (as the lessee). The discount rate implicit in the lease is used to calculate the present value of minimum lease payments. The minimum lease payments consist of the gross lease payments net of executory costs and contingent rentals, if any. Unearned interest is amortized to income over the lease term to produce a constant periodic rate of return on net investment in the lease. While revenue is recognized at the inception of the lease, the cash flow from the sales-type lease occurs over the course of the lease, which results in interest income and reduction of receivables. Revenue is recognized net of value-added tax. B) Contingent Rental Income The Company records income from actual electricity generated of each project in the period the income is earned, which is when the electricity is generated. Contingent rent is not part of minimum lease payments. Operating Leases The Company determines if an arrangement is a lease or contains a lease at inception. Operating lease liabilities are recognized based on the present value of the remaining lease payments, discounted using the discount rate for the lease at the commencement date. As the rate implicit in the lease is not readily determinable for the operating lease, the Company generally uses an incremental borrowing rate based on information available at the commencement date to determine the present value of future lease payments. Operating lease right-of-use (“ROU assets”) assets represent the Company’s right to control the use of an identified asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets are generally recognized based on the amount of the initial measurement of the lease liability. Lease expense is recognized on a straight-line basis over the lease term. The Company elected the package of practical expedients permitted under the transition guidance to combine the lease and non-lease components as a single lease component for operating leases associated with the Company’s office space lease, and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of income on a straight-line basis over the lease term. ROU assets are reviewed for impairment when indicators of impairment are present. ROU assets from operating and finance leases are subject to the impairment guidance in ASC 360, Property, Plant, and Equipment, as ROU assets are long-lived nonfinancial assets. ROU assets are tested for impairment individually or as part of an asset group if the cash flows related to the ROU asset are not independent from the cash flows of other assets and liabilities. An asset group is the unit of accounting for long-lived assets to be held and used, which represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. At September 30, 2021, the ROU was $145,586. The Company recognized no impairment of ROU assets as of September 30, 2021. Operating leases are included in operating lease right-of-use assets and operating lease liabilities (current and non-current), on the consolidated balance sheets. Cash Cash include cash on hand, demand deposits placed with banks or other financial institutions and all highly liquid investments with an original maturity of three months or less as of the purchase date. Accounts Receivable The Company’s policy is to maintain an allowance for potential credit losses on accounts receivable. Management reviews the composition of accounts receivable and analyzes historical bad debts, customer concentrations, customer credit worthiness, current economic trends and changes in customer payment patterns to evaluate the adequacy of these reserves. As of September 30, 2021 and December 31, 2020, the Company had gross accounts receivable of $0 and $342,974 of Erdos TCH for electricity sold, respectively. As of September 30, 2021 and December 31, 2020, the Company had bad debt allowance of $0 and $34,297 for Erdos TCH due to the customer not making the payments as scheduled, respectively. As of September 30, 2021, all outstanding accounts receivable balance was collected in full. Concentration of Credit Risk Cash includes cash on hand and demand deposits in accounts maintained within China. Balances at financial institutions and state-owned banks within the PRC are covered by insurance up to RMB 500,000 (US$76,000) per bank. Any balance over RMB 500,000 (US$76,000) per bank in PRC will not be covered. At September 30, 2021, cash held in the PRC bank of approximately $145,341,795 was not covered by such insurance. The Company has not experienced any losses in such accounts. Certain other financial instruments, which subject the Company to concentration of credit risk, consist of accounts and other receivables. The Company does not require collateral or other security to support these receivables. The Company conducts periodic reviews of its customers’ financial condition and customer payment practices to minimize collection risk on accounts receivable. The operations of the Company are in the PRC. Accordingly, the Company’s business, financial condition and results of operations may be influenced by the political, economic and legal environments in the PRC. Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation. Expenditures for maintenance and repairs are expensed as incurred; additions, renewals and betterments are capitalized. When property and equipment are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the respective accounts, and any gain or loss is included in operations. Depreciation of property and equipment is provided using the straight-line method over the estimated lives as follows: Vehicles 2 - 5 years Office and Other Equipment 2 - 5 years Software 2 - 3 years Impairment of Long-lived Assets In accordance with FASB ASC Topic 360, “Property, Plant, and Equipment Cost of Sales Cost of sales consists primarily of the direct material of the power generating system and expenses incurred directly for project construction for sales-type leasing and sales tax and additions for contingent rental income. Income Taxes Income taxes are accounted for using an asset and liability method. Under this method, deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each period end based on enacted tax laws and statutory tax rates, applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. The Company follows FASB ASC Topic 740, which prescribes a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC Topic 740 also provides guidance on recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting for income taxes in interim periods, and income tax disclosures. Under the provisions of FASB ASC Topic 740, when tax returns are filed, it is likely that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying balance sheets along with any associated interest and penalties that would be payable to the taxing authorities upon examination. Interest associated with unrecognized tax benefits is classified as interest expense and penalties are classified in selling, general and administrative expenses in the statement of income. At September 30, 2021 and December 31, 2020, the Company did not take any uncertain positions that would necessitate recording a tax related liability. Statement of Cash Flows In accordance with FASB ASC Topic 230, “Statement of Cash Flows,” Fair Value of Financial Instruments For certain of the Company’s financial instruments, including cash and equivalents, restricted cash, accounts receivable, other receivables, accounts payable, accrued liabilities and short-term debts, the carrying amounts approximate their fair values due to their short maturities. Receivables on sales-type leases are based on interest rates implicit in the lease. FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” “Financial Instruments,” ● Level 1 inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. ● Level 2 inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. ● Level 3 inputs to the valuation methodology are unobservable and significant to FV measurement. Effective on January 1, 2020, the Company adopted ASU 2018-13, Fair Value Measurement: Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements for Level 1, Level 2 and Level 3 instruments in the FV hierarchy. The Company analyzes all financial instruments with features of both liabilities and equity under FASB ASC 480, “Distinguishing Liabilities from Equity,” “Derivatives and Hedging.” As of September 30, 2021 and December 31, 2020, the Company did not have any long-term debt obligations; and the Company did not identify any assets or liabilities that are required to be presented on the balance sheet at FV. Stock-Based Compensation The Company accounts for share-based compensation awards to employees in accordance with FASB ASC Topic 718, “Compensation – Stock Compensation”, which requires that share-based payment transactions with employees be measured based on the grant-date fair value of the equity instrument issued and recognized as compensation expense over the requisite service period. The Company accounts for share-based compensation awards to non-employees in accordance with FASB ASC Topic 718 and FASB ASC Subtopic 505-50, “Equity-Based Payments to Non-employees”. Share-based compensation associated with the issuance of equity instruments to non-employees is measured at the fair value of the equity instrument issued or committed to be issued, as this is more reliable than the fair value of the services received. The fair value is measured at the date that the commitment for performance by the counterparty has been reached or the counterparty’s performance is complete. Effective on January 1, 2020, the Company adopted ASU 2018-07, “Compensation — Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting,” which expands the scope of ASC 718 to include share-based payment transactions for acquiring goods and services from non-employees. An entity should apply the requirements of ASC 718 to non-employee awards except for specific guidance on inputs to an option pricing model and the attribution of cost. The amendments specify that ASC 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The adoption of ASU 2018-07 did not have an impact on the Company’s financial statements. Basic and Diluted Earnings per Share The Company presents net income (loss) per share (“EPS”) in accordance with FASB ASC Topic 260, “Earning Per Share.” For the nine and three months ended September 30, 2021 and 2020, the basic and diluted loss per share were the same due to the anti-dilutive features of the warrants and options. For the nine and three months ended September 30, 2021, 30,911 shares purchasable under warrants and options were excluded from the EPS calculation as these were not dilutive due to the exercise price was more than the stock market price. For the nine and three months ended September 30, 2020, 31,311 shares purchasable under warrants and options were excluded from the EPS calculation as these were not dilutive due to the exercise price was more than the stock market price. Foreign Currency Translation and Comprehensive Income (Loss) The Company’s functional currency is the Renminbi (“RMB”). For financial reporting purposes, RMB were translated into United States Dollars (“USD” or “$”) as the reporting currency. Assets and liabilities are translated at the exchange rate in effect at the balance sheet date. Revenues and expenses are translated at the average rate of exchange prevailing during the reporting period. Translation adjustments arising from the use of different exchange rates from period to period are included as a component of stockholders’ equity as “Accumulated other comprehensive income.” Gains and losses resulting from foreign currency transactions are included in income. There was no significant fluctuation in the exchange rate for the conversion of RMB to USD after the balance sheet date. The Company follows FASB ASC Topic 220, “Comprehensive Income.” Segment Reporting FASB ASC Topic 280, “Segment Reporting,” New Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326), which requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early application will be permitted for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact that the standard will have on its CFS. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance should be adopted on a prospective basis. As a smaller reporting company, the standard will be effective for the Company for interim and annual reporting periods beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04”). ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. The Company continues to evaluate the impact of the guidance and may apply the elections as applicable as changes in the market occur. In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470- 20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity. This ASU (1) simplifies the accounting for convertible debt instruments and convertible preferred stock by removing the existing guidance in ASC 470-20, Debt: Debt with Conversion and Other Options, that requires entities to account for beneficial conversion features and cash conversion features in equity, separately from the host convertible debt or preferred stock; (2) revises the scope exception from derivative accounting in ASC 815-40 for freestanding financial instruments and embedded features that are both indexed to the issuer’s own stock and classified in stockholders’ equity, by removing certain criteria required for equity classification; and (3) revises the guidance in ASC 260, Earnings Per Share, to require entities to calculate diluted earnings per share (EPS) for convertible instruments by using the if-converted method. In addition, entities must presume share settlement for purposes of calculating diluted EPS when an instrument may be settled in cash or shares. For SEC filers, excluding smaller reporting companies, ASU 2020-06 is effective for fiscal years beginning after December 15, 2021 including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. For all other entities, ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Entities should adopt the guidance as of the beginning of the fiscal year of adoption and cannot adopt the guidance in an interim reporting period. The Company is currently evaluating the impact that ASU 2020-06 may have on its consolidated financial statements and related disclosures. Other recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the SEC did not or are not believed by management to have a material impact on the Company’s present or future CFS.	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The consolidated financial statements (“CFS”) were prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). Basis of Consolidation The CFS include the accounts of CREG and its subsidiaries, Shanghai Yinghua Financial Leasing Co., Ltd. (“Yinghua”) and Sifang Holdings; Sifang Holdings’ wholly owned subsidiaries, Huahong New Energy Technology Co., Ltd. (“Huahong”) and Shanghai TCH Energy Tech Co., Ltd. (“Shanghai TCH”); Shanghai TCH’s wholly-owned subsidiary, Xi’an TCH Energy Tech Co., Ltd. (“Xi’an TCH”); and Xi’an TCH’s subsidiaries, 1) Erdos TCH Energy Saving Development Co., Ltd (“Erdos TCH”), 100% owned by Xi’an TCH (See note 1), 2) Zhonghong, 90% owned by Xi’an TCH and 10% owned by Shanghai TCH, and 3) Zhongxun, 100% owned by Xi’an TCH. Substantially all the Company’s revenues are derived from the operations of Shanghai TCH and its subsidiaries, which represent substantially all the Company’s consolidated assets and liabilities as of December 31, 2020. However, there was no revenue for the Company for the year ended December 31, 2020. All significant inter-company accounts and transactions were eliminated in consolidation. Uses and Sources of Liquidity For the year ended December 31, 2020, the Company had a net income of $4.05 million based on receipts of accounts receivable which had previously been reserved as bad debt allowance and was reversed in 2020. For the year ended December 31, 2019, the Company had net loss of $8.77 million. The Company had an accumulated deficit of $43.03 million as of December 31, 2020. The Company disposed all of its systems and currently holds only five power generating systems through Erdos TCH, which is expected to resume production in July 2021. The Company is in the process of transforming and expanding into an energy storage integrated solution provider. The Company plans to pursue disciplined and targeted expansion strategies for market areas the Company currently does not serve. The Company actively seeks and explores opportunities to apply energy storage technologies to new industries or segments with high growth potential, including industrial and commercial complexes, large scale photovoltaic (PV) and wind power stations, remote islands without electricity, and smart energy cities with multi-energy supplies. The Company had cash of $107.80 million as of December 31, 2020, and has raised additional $38.25 million in a private offering in March 2021. The Company’s cash flow forecast indicate it will have sufficient cash to funds its operations for the next 12 months from the date of issuance of these financial statements. The historical operating results indicate the Company has recurring losses from operations which rise the question related to the Company’s ability to continue as a going concern. However, the Company had $107.80 million cash on hand at December 31, 2020 as a result of collection the full payment from all the projects that had been disposed earlier. The ability of the Company to continue as a going concern is dependent upon the Company’s ability to further implement its business plan and generate sufficient revenue and its ability to raise additional funds by way of a public or private offering, or debt financing including bank loans. The consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties. Use of Estimates In preparing these CFS in accordance with US GAAP, management makes estimates and assumptions that affect the reported amounts of assets and liabilities in the balance sheets as well as revenues and expenses during the period reported. Actual results may differ from these estimates. On an on-going basis, management evaluates their estimates, including those related to allowances for bad debt and inventory obsolescence, impairment loss on fixed assets and construction in progress, income taxes, and contingencies and litigation. Management bases their estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other resources. Revenue Recognition A) Sales-type Leasing and Related Revenue Recognition On January 1, 2019, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 842 using the modified retrospective transition approach by applying the new standard to all leases existing at the date of initial application. Results and disclosure requirements for reporting periods beginning after January 1, 2019 are presented under ASC Topic 842, while prior period amounts have not been adjusted and continue to be reported in accordance with our historical accounting under Topic 840. (See Operating lease below as relates to the Company as a lessee). The Company’s sales type lease contracts for revenue recognition fall under ASC 842. During the years ended December 31, 2020 and 2019, the Company did not sell any new power generating projects. The Company constructs and leases waste energy recycling power generating projects to its customers. The Company typically transfers legal ownership of the waste energy recycling power generating projects to its customers at the end of the lease. Prior to January 1, 2019, the investment in these projects was recorded as investment in sales-type leases in accordance with ASC Topic 840 , “Lease ,” The Company finances construction of waste energy recycling power generating projects. The sales and cost of sales are recognized at the inception of the lease, which is when the control is transferred to the lessee. The Company accounts for the transfer of control as a sales type lease in accordance with ASC 842-10-25-2. The underlying asset is derecognized, and revenue is recorded when collection of payments is probable. This is in accordance with the revenue recognition principle in ASC 606 - Revenue from contracts with customers. The investment in sales-type leases consists of the sum of the minimum lease payments receivable less unearned interest income and estimated executory cost. Minimum lease payments are part of the lease agreement between the Company (as the lessor) and the customer (as the lessee). The discount rate implicit in the lease is used to calculate the present value of minimum lease payments. The minimum lease payments consist of the gross lease payments net of executory costs and contingent rentals, if any. Unearned interest is amortized to income over the lease term to produce a constant periodic rate of return on net investment in the lease. While revenue is recognized at the inception of the lease, the cash flow from the sales-type lease occurs over the course of the lease, which results in interest income and reduction of receivables. Revenue is recognized net of value-added tax. B) Contingent Rental Income The Company records income from actual electricity generated of each project in the period the income is earned, which is when the electricity is generated. Contingent rent is not part of minimum lease payments. Operating Leases On January 1, 2019, the Company adopted Topic 842 using the modified retrospective transition approach by applying the new standard to all leases existing at the date of initial application. Results and disclosure requirements for reporting periods beginning after January 1, 2019 are presented under Topic 842, while prior period amounts have not been adjusted and continue to be reported in accordance with its historical accounting under Topic 840. The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company elected the package of practical expedients permitted under the transition guidance, which allowed it to carry forward its historical lease classification, its assessment on whether a contract was or contains a lease, and its initial direct costs for any leases that existed prior to January 1, 2019. The Company also elected to combine its lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of income on a straight-line basis over the lease term. The Company leased an office in Xi’an, China as the Company’s headquarter; upon adoption, the Company recognized total Right of Use Asset (“ROU”) of $116,917, with corresponding liabilities of $116,917 on the consolidated balance sheets. The ROU assets include adjustments for prepayments and accrued lease payments. The adoption did not impact its beginning retained earnings, or its prior year consolidated statements of income and statements of cash flows. At December 31, 2020, the ROU was $0 as the lease was expired in November 2020. Under Topic 842, the Company determines if an arrangement is a lease at inception. ROU assets and liabilities are recognized at commencement date based on the present value of remaining lease payments over the lease term. For this purpose, the Company considers only payments that are fixed and determinable at the time of commencement. As most of its leases do not provide an implicit rate, it uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The Company’s incremental borrowing rate is a hypothetical rate based on its understanding of what its credit rating would be. The ROU asset also includes any lease payments made prior to commencement and is recorded net of any lease incentives received. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that it will exercise such options. Operating leases are included in operating lease right-of-use assets and operating lease liabilities (current and non-current), on the consolidated balance sheets. Cash Cash include cash on hand, demand deposits placed with banks or other financial institutions and all highly liquid investments with an original maturity of three months or less as of the purchase date. Accounts Receivable The Company’s policy is to maintain an allowance for potential credit losses on accounts receivable. Management reviews the composition of accounts receivable and analyzes historical bad debts, customer concentrations, customer credit worthiness, current economic trends and changes in customer payment patterns to evaluate the adequacy of these reserves. As of December 31, 2020, the Company had gross accounts receivable of $342,974 of Erdos TCH for electricity sold. As of December 31, 2019, the Company had gross accounts receivable of $48.06 million; of which, $35.42 million was for transferring the ownership of Huayu and Shenqiu Phase I and II systems to Mr. Bai; $10.03 million was from the sales of CDQ and a CDQ WHPG system to Zhongtai, and $2.61 million accounts receivable of Erdos TCH for electricity sold. As of December 31, 2020, the Company had bad debt allowance of $34,297 for Erdos TCH due to the customer not making the payments as scheduled. As of December 31, 2019, the Company had bad debt allowance of $5,733,781 for Zhongtai and $261,430 for Erdos TCH due to the customer not making the payments as scheduled. During the year ended December 31, 2020, the Company recognized a reversal of the bad debt allowance of $6,031,058, of which $5,799,094 was for Zhongtai and $231,964 was for Erdos TCH as a result of payment collection from Zhongtai and Erdos TCH. As of December 31, 2020, the Company received the payment in full from all the projects which had been disposed earlier. 2020 2019 Xuzhou Zhongtai project $ - $ 10,034,116 Bai Chonggong (for Shenqiu and Huayu projects) - 35,415,556 Xuzhou Tian’an project - - Receivable of electricity sales of Erdos 342,974 2,614,299 Total accounts receivable 342,974 48,063,971 Bad debt allowance (34,297 ) (5,995,210 ) Accounts receivable, net 308,677 $ 42,068,761 Interest Receivable on Sales Type Leases As of December 31, 2020, the interest receivable on sales type leases was $0. As of December 31, 2019, the interest receivable on sales type leases was $5,245,244, mainly from recognized but not yet collected interest income for the Pucheng systems. The ownership of Pucheng systems was transferred to Pucheng as a result of full payment received by Xi’an TCH in January 2020. Investment in sales-type leases, net As of December 31, 2020, the Company had net investment in sales-type leases of $0. As of December 31, 2019, the Company had net investment in sales-type leases of $8,287,560 (after bad debt allowance for investment in sales-type leases of $24,416,441 for the Pucheng system). The Company maintains reserves for potential credit losses on receivables. Management reviews the composition of receivables and analyzes historical bad debts, customer concentrations, customer credit worthiness, current economic trends and changes in customer payment patterns to evaluate the adequacy of these reserves. Concentration of Credit Risk Cash includes cash on hand and demand deposits in accounts maintained within China. Balances at financial institutions and state-owned banks within the PRC are covered by insurance up to RMB 500,000 (US$77,000) per bank. Any balance over RMB 500,000 (US$77,000) per bank in PRC will not be covered. At December 31, 2020, cash held in the PRC bank of $107,510,548 was not covered by such insurance. The Company has not experienced any losses in such accounts. Certain other financial instruments, which subject the Company to concentration of credit risk, consist of accounts and other receivables. The Company does not require collateral or other security to support these receivables. The Company conducts periodic reviews of its customers’ financial condition and customer payment practices to minimize collection risk on accounts receivable. The operations of the Company are in the PRC. Accordingly, the Company’s business, financial condition and results of operations may be influenced by the political, economic and legal environments in the PRC. Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation. Expenditures for maintenance and repairs are expensed as incurred; additions, renewals and betterments are capitalized. When property and equipment are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the respective accounts, and any gain or loss is included in operations. Depreciation of property and equipment is provided using the straight-line method over the estimated lives as follows: Vehicles 2 - 5 years Office and Other Equipment 2 - 5 years Software 2 - 3 years Impairment of Long-lived Assets In accordance with FASB ASC Topic 360, “Property, Plant, and Equipment Cost of Sales Cost of sales consists primarily of the direct material of the power generating system and expenses incurred directly for project construction for sales-type leasing and sales tax and additions for contingent rental income. Income Taxes Income taxes are accounted for using an asset and liability method. Under this method, deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each period end based on enacted tax laws and statutory tax rates, applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. The Company follows FASB ASC Topic 740, which prescribes a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC Topic 740 also provides guidance on recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting for income taxes in interim periods, and income tax disclosures. Under the provisions of FASB ASC Topic 740, when tax returns are filed, it is likely that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying balance sheets along with any associated interest and penalties that would be payable to the taxing authorities upon examination. Interest associated with unrecognized tax benefits is classified as interest expense and penalties are classified in selling, general and administrative expenses in the statement of income. At December 31, 2020 and 2019, the Company did not take any uncertain positions that would necessitate recording a tax related liability. Statement of Cash Flows In accordance with FASB ASC Topic 230, “Statement of Cash Flows,” Fair Value of Financial Instruments For certain of the Company’s financial instruments, including cash and equivalents, restricted cash, accounts receivable, other receivables, accounts payable, accrued liabilities and short-term debts, the carrying amounts approximate their fair values due to their short maturities. Receivables on sales-type leases are based on interest rates implicit in the lease. FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” “Financial Instruments,” ● Level 1 inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. ● Level 2 inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. ● Level 3 inputs to the valuation methodology are unobservable and significant to FV measurement. Effective on January 1, 2020, the Company adopted ASU 2018-13, Fair Value Measurement: Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements for Level 1, Level 2 and Level 3 instruments in the FV hierarchy. The Company analyzes all financial instruments with features of both liabilities and equity under FASB ASC 480, “Distinguishing Liabilities from Equity,” “Derivatives and Hedging.” As of December 31, 2020 and 2019, the Company did not have any long-term debt obligations; and the Company did not identify any assets or liabilities that are required to be presented on the balance sheet at FV. Stock-Based Compensation The Company accounts for share-based compensation awards to employees in accordance with FASB ASC Topic 718, “Compensation – Stock Compensation”, which requires that share-based payment transactions with employees be measured based on the grant-date fair value of the equity instrument issued and recognized as compensation expense over the requisite service period. The Company accounts for share-based compensation awards to non-employees in accordance with FASB ASC Topic 718 and FASB ASC Subtopic 505-50, “Equity-Based Payments to Non-employees”. Share-based compensation associated with the issuance of equity instruments to non-employees is measured at the fair value of the equity instrument issued or committed to be issued, as this is more reliable than the fair value of the services received. The fair value is measured at the date that the commitment for performance by the counterparty has been reached or the counterparty’s performance is complete. Effective on January 1, 2020, the Company adopted ASU 2018-07, “Compensation — Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting,” which expands the scope of ASC 718 to include share-based payment transactions for acquiring goods and services from non-employees. An entity should apply the requirements of ASC 718 to non-employee awards except for specific guidance on inputs to an option pricing model and the attribution of cost. The amendments specify that ASC 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The adoption of ASU 2018-07 did not have an impact on the Company’s financial statements. Basic and Diluted Earnings per Share The Company presents net income (loss) per share (“EPS”) in accordance with FASB ASC Topic 260, “Earning Per Share.” For the years ended December 31, 2020 and 2019, the basic and diluted loss per share were the same due to the anti-dilutive features of the warrants and options. For the years ended December 31, 2020 and 2019, 31,311 shares and 406,764 shares (post-reverse stock split), respectively; purchasable under warrants and options were excluded from the EPS calculation as these were not dilutive due to the exercise price was more than the stock market price. Foreign Currency Translation and Comprehensive Income (Loss) The Company’s functional currency is the Renminbi (“RMB”). For financial reporting purposes, RMB were translated into United States Dollars (“USD” or “$”) as the reporting currency. Assets and liabilities are translated at the exchange rate in effect at the balance sheet date. Revenues and expenses are translated at the average rate of exchange prevailing during the reporting period. Translation adjustments arising from the use of different exchange rates from period to period are included as a component of stockholders’ equity as “Accumulated other comprehensive income.” Gains and losses resulting from foreign currency transactions are included in income. There was no significant fluctuation in the exchange rate for the conversion of RMB to USD after the balance sheet date. The Company follows FASB ASC Topic 220, “Comprehensive Income.” Segment Reporting FASB ASC Topic 280, “Segment Reporting,” New Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326), which requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early application will be permitted for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact that the standard will have on its CFS. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistent application among reporting entities. The guidance is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years, with early adoption permitted. Upon adoption, the Company must apply certain aspects of this standard retrospectively for all periods presented while other aspects are applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company is evaluating the impact this update will have on its financial statements. Other recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the SEC did not or are not believed by management to have a material impact on the Company’s present or future CFS.

ASSET SUBJECT TO BUYBACK	4. ASSET SUBJECT TO BUYBACK As of September 30, 2021 and December 31, 2020, the Company had asset subject to buyback of $0 and $28.92 million, respectively, which was for the Chengli project. The Chengli project finished construction, and was transferred to the Company’s fixed assets at a cost of $35.24 million (without impairment loss) and ready to be put into operation as of December 31, 2018. On January 22, 2019, Xi’an Zhonghong completed the transfer of Chengli CDQ WHPG project as the partial repayment for the loan and accrued interest of RMB 188,639,400 ($27.54 million) to HYREF (see Note 8). On April 9, 2021, Xi’an TCH, Xi’an Zhonghong, Guohua Ku, Chonggong Bai and HYREF entered a Termination of Fulfillment Agreement (termination agreement). Under the termination agreement, the original buyback agreement entered on December 19, 2019 was terminated upon signing of the termination agreement. HYREF will not execute the buy-back option and will not ask for any additional payment from the buyers other than keeping the CDQ WHPG station. As a result of the termination of the buy-back agreement, the Company recorded a gain of approximately $3.1 million from transferring the CDP WHPG station to HYREF as partial repayment of the entrusted loan, which is the difference between the carrying value of the assets and loan and interest payable on the loan.	5.

In the fourth quarter of 2015, three power stations of Erdos TCH were pledged to Industrial Bank as an additional guarantee for the loan to Zhonghong’s three CDQ WHPG systems. In 2016, two additional power stations of Erdos TCH and Pucheng Phase I and II systems were pledged to Industrial Bank as an additional guarantee along with Xi’an TCH’s equity in Zhonghong.

As of December 31, 2020, the interest payable for this loan was $10.14 million and the outstanding balance for this loan was $22.20 million including a non-current portion of $0.30 million.

INCOME TAX	12. INCOME TAX The Company’s Chinese subsidiaries are governed by the Income Tax Law of the PRC concerning privately-run enterprises, which are generally subject to tax at 25% on income reported in the statutory financial statements after appropriate tax adjustments. Under Chinese tax law, the tax treatment of finance and sales-type leases is similar to US GAAP. However, the local tax bureau continues to treat the Company’s sales-type leases as operating leases. Accordingly, the Company recorded deferred income taxes. The Company’s subsidiaries generate all of their income from their PRC operations. All of the Company’s Chinese subsidiaries’ effective income tax rate for 2021 and 2020 was 25%. Yinghua, Shanghai TCH, Xi’an TCH, Huahong, Zhonghong and Erdos TCH file separate income tax returns. There is no income tax for companies domiciled in the Cayman Islands. Accordingly, the Company’s CFS do not present any income tax provisions related to Cayman Islands tax jurisdiction, where Sifang Holding is domiciled. The US parent company, CREG is taxed in the US and, as of September 30, 2021, had net operating loss (“NOL”) carry forwards for income taxes of $1.98 million; for federal income tax purposes, the NOL arising in tax years beginning after 2017 may only reduce 80% of a taxpayer’s taxable income, and may be carried forward indefinitely. However, the coronavirus Aid, Relief and Economic Security Act (“the CARES Act”) issued in March 2020, provides tax relief to both corporate and noncorporate taxpayers by adding a five-year carryback period and temporarily repealing the 80% limitation for NOLs arising in 2018, 2019 and 2020. The management believes the realization of benefits from these losses may be uncertain due to the US parent company’s continuing operating losses. Accordingly, a 100% deferred tax asset valuation allowance was provided. As of September 30, 2021, the Company’s PRC subsidiaries had $10.50 million NOL that can be carried forward to offset future taxable income for five years from the year the loss is incurred. The NOL was mostly from Erdos TCH and Zhonghong. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. After consideration of all the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets due to the recurring losses from operations of these entities, accordingly, the Company recorded a 100% deferred tax valuation allowance for PRC NOL. The following table reconciles the U.S. statutory rates to the Company’s effective tax rate for the nine months ended September 30, 2021 and 2020, respectively: 2021 2020 U.S. statutory rates 21.0 % (21.0 )% Tax rate difference – current provision 10.1 % 9.8 % Prior year income tax adjustment in current year (8.8 )% Permanent differences 16.1 % 41.3 % Change in valuation allowance (45.2 )% (30.1 )% Tax benefit per financial statements (6.7 )% - % The provision for income tax expense for the nine months ended September 30, 2021 and 2020 consisted of the following: 2021 2020 Income tax benefit – current $ 87,051 $ - Income tax benefit – deferred - - Total income tax benefit $ 87,051 $ - The following table reconciles the U.S. statutory rates to the Company’s effective tax rate for the three months ended September 30, 2021 and 2020, respectively: 2021 2020 U.S. statutory rates (21.0 )% (21.0 )% Tax rate difference – current provision 0.3 % (1.9 )% Permanent differences 35.7 % 9.5 % Change in valuation allowance (13.0 )% 13.4 % Tax expense per financial statements 2.0 % - % The provision for income tax expense for the three months ended September 30, 2021 and 2020 consisted of the following: 2021 2020 Income tax expense – current $ 10,902 $ - Income tax expense– deferred - - Total income tax expense $ 10,902 $ -	14.

strain of coronavirus (COVID-19) was reported in and the World Health Organization has declared the outbreak to constitute a “Public
Health Emergency of International Concern.” This pandemic, which continues to spread to additional countries, and is disrupting
supply chains and affecting production and sales across a range of industries as a result of quarantines, facility closures, and travel
and logistics restrictions in connection with the outbreak. However, as a result of PRC government’s effort on disease control,
most cities in China were reopened, the outbreak in China is under the control. The Company disposed all of its systems and currently
holds only five power generating systems through Erdos TCH, the Company initially expected to resume production of these five power generating
systems in July 2020 from the renovation and furnace safety upgrade, but the resumption of operations was further delayed due to government’s
request for Erdos’ production line rectification for lowering its energy consumption per unit of GDP; the Company expects the resumption
date to be July 2021. As of this report date, there are some new Covid-19 cases discovered in a few provinces of China, however, the
number of new cases is not significant due to PRC government’s strict control. On December 22, 2020, Shanghai
TCH entered into an Equity Acquisition Agreement with Xi’an Taiying Energy Saving Technology Co., Ltd.

As consideration for the transfer of the Project, Zhongtai agreed to pay to
Xi’an TCH RMB 167,360,000 ($25.77 million) including (i) RMB 152,360,000 ($23.46 million) for the construction of the Project;
and (ii) RMB 15,000,000 ($2.31 million) as payment for partial loan interest accrued during the construction period. Those amounts have
