Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	Note 1—Basis of Presentation and Business Changes and Development The accompanying unaudited condensed consolidated financial statements of Genie Energy Ltd. and its subsidiaries (the “Company” or “Genie”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025. The consolidated balance sheet at December 31, 2024 has been derived from the Company’s audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. For further information, please refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the U.S. Securities and Exchange Commission (the “SEC”). The Company owns 100% of Genie Retail Energy (“GRE”) and varied interests in entities that comprise the Genie Renewables ("GREW") segment. GRE owns and operates retail energy providers (“REPs”), including IDT Energy (“IDT Energy”), Residents Energy (“Residents Energy”), Town Square Energy and Town Square Energy East (collectively, "TSE"), Southern Federal Power ("Southern Federal"), Mirabito Natural Gas (“Mirabito”) and Evergreen Gas & Electric (“Evergreen”). The majority of GRE's REP customers are located in the Eastern and Midwestern United States and Texas. Mirabito supplies natural gas to commercial customers in Florida. GREW primarily consists of a 95.5% interest in Genie Solar, an integrated solar energy company, a 92.8% interest in CityCom Solar, a marketer of community solar and alternative products and services complimentary to our energy offerings, and a 91.5% interest in Diversegy, an energy procurement advisor for industrial, commercial and municipal customers. One Big Beautiful Bill Act On July 4, 2025, the One Big Beautiful Bill Act (“OBBB”) was enacted into law. The law accelerates the expiration of the federal investment tax credit on solar projects, effective for projects going online after December 31, 2027. In light of this new law, the Company is evaluating the financial viability of its early-stage projects that will not qualify for the federal solar investment tax credits and is pausing new project developments. The Company is evaluating the impact of this legislation on our solar operations and potential future impact on its condensed consolidated financial statements. Impairment of assets Impairment of assets is a result of discontinued projects of Genie Solar as a result of lack of viability. The Company recognized the impairment of assets related to costs previously capitalized in other current assets in the condensed consolidated balance sheets. Discontinued Operations in Finland and Sweden Prior to the third quarter of 2022, the Company had a third segment, Genie Retail Energy International, or GRE International, which supplied electricity to residential and small business customers in Scandinavia. However, as a result of volatility in the energy market in Europe, in the third quarter of 2022, the Company decided to discontinue the operations of Lumo Energia Oyj ("Lumo Finland") and Lumo Energi AB ("Lumo Sweden"). The Company accounts for these businesses as discontinued operations, and accordingly, presents the results of operations and related cash flows as discontinued operations. The results of operations and related cash flows are presented as discontinued operations for all periods. Any remaining assets and liabilities of the discontinued operations are presented separately and reflected within assets and liabilities from discontinued operations in the accompanying condensed consolidated balance sheets as of June 30, 2025 and December 31, 2024. Lumo Sweden is continuing to liquidate their remaining receivables and settle any remaining liabilities. Following the discontinuance of operations of Lumo Finland and Lumo Sweden, GRE International ceased to be a segment and the remaining assets and liabilities and results of continuing operations of GRE International were combined with corporate. Seasonality and Weather; Climate Change and Volatility in Pricing The weather and the seasons, among other things, affect GRE’s revenues. Weather conditions have a significant impact on the demand for natural gas used for heating and electricity used for heating and cooling. Typically, colder winters increase demand for natural gas and electricity, and hotter summers increase demand for electricity. Milder winters or summers have the opposite effect. Unseasonal temperatures in other periods may also impact demand levels. Natural gas revenues typically increase in the first quarter due to increased heating demands and electricity revenues typically increase in the third quarter due to increased air conditioning use. Approximately 43.0% and 48.1% of GRE’s natural gas revenues for the relevant years were generated in the first quarters 2024 and 2023, respectively, when demand for heating was highest. Although the demand for electricity is not as seasonal as natural gas (due, in part, to usage of electricity for both heating and cooling), approximately 28.7% and 32.5% of GRE’s electricity revenues were generated in the third quarters of 2024 and 2023 respectively. GRE’s REPs’ revenues and operating income are subject to material seasonal variations, and the interim financial results are not necessarily indicative of the estimated financial results for the full year. In addition, extraordinary weather has and can lead to extreme spikes in the prices of wholesale electricity and natural gas in markets where GRE and other retail providers purchase their supply, or in challenges to the grid or supply markets in affected areas. Such events could have material impacts on our margins and operations. In addition to the direct physical impact that climate change may have on the Company's business, financial condition and results of operations because of the effect on pricing, demand for our offerings and/or the energy supply markets, we may also be adversely impacted by other environmental factors, including: (i) technological advances designed to promote energy efficiency and limit environmental impact; (ii) increased competition from alternative energy sources; (iii) regulatory responses aimed at decreasing greenhouse gas emissions; and (iv) litigation or regulatory actions that address the environmental impact of our energy products and services.
