Basis of Presentation [Abstract]
Basis of Presentation	Note 1—Basis of Presentation The accompanying unaudited 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 10 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 months ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending . The balance sheet at December 31, 2020 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, 2020, as filed with the U.S. Securities and Exchange Commission (the “SEC”). Refer to Note 17 for a discussion related to an immaterial correction to the December 31, 2020 segment assets disclosure. The Company owns 99.3% of its subsidiary, Genie Energy International Corporation (“GEIC”), which owns 100% of Genie Retail Energy (“GRE”), 100% of Genie Retail Energy International LLC ("GRE International" or "GREI") and 100% of Genie Renewable. In March 2021, the Company modified its management reporting to rename the Genie Energy Services ("GES") segment to Genie Renewables segment. GRE owns and operates retail energy providers (“REPs”), including IDT Energy, Inc. (“IDT Energy”), Residents Energy, Inc. (“Residents Energy”), Town Square Energy, LLC and Town Square Energy East, LLC (collectively, "TSE"), Southern Federal Power LLC ("Southern Federal") and Mirabito Natural Gas (“Mirabito”). GRE's REP businesses resell electricity and natural gas to residential and small business customers primarily in the Eastern and Midwestern United States and Texas . GRE International holds the Company's 100% interest in Shoreditch Energy Limited, a REP that serves retail customers in the United Kingdom under the name Orbit Energy, and its 98.8% interest in venture in Japan, which launched commercial operations in second quarter of 2019, the Company's 91.7% interest in Lumo Energia Oyj ("Lumo Finland"), a REP serving residential customers in Finland, and its 98.9% interest in Lumo Energi AB ("Lumo Sweden"), which was formed in 2019 to serve retail energy customers in Sweden. Genie Renewables oversees Diversegy LLC (" "), a retail energy advisory and brokerage company that serves commercial and industrial customers throughout the United States, manages Prism Solar Technology, Inc. ("Prism"), a solar solutions company that is engaged in U.S.-based manufacturing of solar panels, solar installation design and solar energy project management, Genie Solar Energy, a rooftop solar system sales and general contracting company and CityCom Solar, a marketer of community solar energy solution. Energy Price Volatility in Texas and Japan In January 2021, weather volatility and the lack of adequate gas reserves significantly increased the price of energy at Japan Electric Power Exchange ("JEPX") for an extended period of time. The spike in demand associated with this situation, exposed Genie Japan to unexpected cost increases. Genie Japan incurred approximately costs related to the price increases, which were included in the cost of revenue in the three months ended March 31, 2021. In February of 2021, the State of Texas experienced unprecedented cold weather and snow. With the grid overtaxed due to demand and weather-related reduced supply and rolling blackouts being enforced, by order of the Electricity Reliability Council of Texas ("ERCOT"), real-time commodity prices during the crisis escalated significantly. Although GRE's commitment for their customers in Texas was reasonably hedged for reasonably foreseen winter weather conditions, the market conditions exposed the Company to significant unexpected cost increases. GRE recognized approximately $13.0 million in additional costs related to the situation, which were in the cost of revenue for the three months ended March 31, 2021. Seasonality and Weather 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. Unseasonable 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 47.7% and 46.9% of GRE’s natural gas revenues for the relevant years were generated in the first quarters of 2020 and 2019, 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 31.8% of GRE’s electricity revenues for the relevant years were generated in the third quarters of 2020 and 2019. 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. 7 Coronavirus Disease (COVID- 19 Starting in the first quarter of 2020 2019 19 For the three months ended March 31, 2021, the impacts of COVID-19 are evident in several key aspects of the Company's business operations and the corresponding financial impact has been mixed. The Company's customer base is predominantly residential, so the Company has benefited from the increased demand for residential electricity as many customers are working from and spending more time in their homes. On the other hand, like other retail providers, the Company suspended its face-to-face customer acquisition programs in March 2020 as public health measures were implemented to combat COVID-19, resulting in a decrease in gross meter acquisitions. The reduction in gross meter acquisitions decreased customer acquisition expenses in the first quarter of 2021 and resulted in a slight decline in domestic meters served during the first quarter of 2021. Churn for the first quarter of 2021 decreased, in part, as the Company's competitors also suspended their face to face marketing programs. In the fourth quarter of 2020, authorities began relaxing certain COVID-19 public health restrictions in some of GRE's domestic markets facilitating a partial reactivation of the previously curtailed customer acquisition channels. There are many uncertainties regarding the impacts of the COVID- 19

Revenue Recognition

Revenue Recognition [Abstract]
Revenue Recognition	Note 4—Revenue Recognition Revenue from the single performance obligation to deliver a unit of electricity and/or natural gas is recognized as the customer simultaneously receives and consumes the benefit. GRE and Genie Japan record unbilled revenues for the estimated amount customers will be billed for services rendered from the time meters were last read to the end of the respective accounting period. The unbilled revenue is estimated each month based on available per day usage data, the number of unbilled days in the period and historical trends. Several utility companies offer purchase of receivable, or POR, programs in most of the service territories in which GRE operates, and participate in POR programs for a majority of their receivables. The Company estimates variable consideration related to its rebate programs using the expected value method and a portfolio approach. The Company’s estimates related to rebate programs are based on the terms of the rebate program, the customer’s historical electricity and natural gas consumption, the customer’s rate plan, and a churn factor. Taxes that are imposed on the Company’s sales and collected from customers are excluded from the transaction price. Revenues from Shoreditch are accrued based on an estimate of the quantity in units of electricity or natural gas supplied to customers by profile class. The estimate is made using historical consumption patterns, industry estimated consumption rates, and takes into consideration industry reconciliation processes. Revenue from sales of solar panels are recognized at a point in time following the transfer of control of the solar panels to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying contracts. For sales contracts that contain multiple performance obligations, such as the shipment or delivery of solar modules, the Company allocates the transaction price to each performance obligation identified in the contract based on relative standalone selling prices, or estimates of such prices, and recognize the related revenue as control of each individual product is transferred to the customer, in satisfaction of the corresponding performance obligations. Revenues from sale of solar panels are included in other revenues in the consolidated statements of operations. The Company recognizes the incremental costs of obtaining a contract with a customer as an asset if it expects the benefit of those costs to be longer than one year. The Company determined that certain sales commissions to acquire customers meet the requirements to be capitalized. For GRE, the Company applies a practical expedient to expense costs as incurred for sales commissions to acquire customers as the period would have been one year or less. Incremental customer acquisition cost of certain GRE International entities are capitalized and amortized over the range of between eighteen twenty-four . These costs and the related amortization are recorded within sales and marketing expenses. Total capitalized customer acquisition costs to obtain customer contracts were $0.3 million an d $0.2 milli months ended March 31, 2021 and 2020 , respectively. At March 31, 2021, customer acquisition costs of $0.5 million and $0.1 million included in other current assets and other assets, respectively, on the consolidated balance sheet. The Company recognized $0.2 million of amortization of capitalized customer acquisition cost, in each of the three months ended March 31, 2021 and 2020.

These advance payments received under revenue contracts are recognized as revenue as the Company satisfies the performance obligations to the other party. A portion of the transaction price allocated to the performance obligations to be satisfied in the future periods is recognized as contract liability. Customers of Shoreditch can elect to be on a budget plan. Under this type of plan, a monthly installment amount is calculated based on estimated annual usage. Contract liabilities are adjusted monthly based on actual and estimated usage of the customers. Annually, the budget plan is reconciled to actual annual usage. The following table summarized the changes in the liabilities.

GEUK, therefore, accounted for its ownership interest in Shoreditch using the equity method since GEUK had the ability to exercise significant influence over its operating and financial matters, although it did not control Shoreditch. On October 8, 2020 2018 Following the transaction, EGC has no rights in the management of Shoreditch and GEUK has complete control over the activities of Shoreditch. The Company recorded revenue for Shoreditch of approximately $27.9 million in its consolidated statements of operations the three months ended March 31, 2021 The Company conducted an assessment of assets and liabilities related to the acquisition of Shoreditch. The impact of the acquisition’s purchase price allocations on the Company’s consolidated balance sheet and the acquisition date fair value of the total consideration transferred were as follows: (in thousands) Cash $ 2,681 Trade accounts receivable 8,008 Other current assets 843 Intangible assets: Trademark (10-year useful life) 1,594 Non-compete agreements (2-year useful life) 1,956 Customer relationship (2-year useful life) 3,620 Goodwill 13,426 Other assets 657 Accounts and other current liabilities (20,490 ) Noncontrolling interest (5,152 ) Net assets $ 7,143 Goodwill was allocated to the GRE International segment. Goodwill is the excess of the consideration transferred over the net assets recognized and represents the expected revenue and cost synergies of the combined company and assembled workforce. Goodwill recognized as a result of the acquisition is not deductible for income tax purposes. The Company recognized a gain of $5.5 million upon consolidation of Shoreditch in the consolidated statement of operations for the year ended December 31, 2020, pertaining to the estimated fair value of the Company's noncontrolling interest prior to the acquisition, which is based on the amount paid by the Company for the remaining 23.0% of Shoreditch. The net book value of the Company's investments in Shoreditch was nil immediately prior to the acquisition. Pro forma Results (unaudite The following unaudited pro forma financial information summarizes the results of operations for the three months ended March 31, 2020 as if the acquisition of Shoreditch had been completed as of the beginning of 2019. The pro forma results are based upon certain assumptions and estimates, and they give effect to actual operating results prior to the acquisitions and adjustments to reflect (i) the change in depreciation expense and intangible assets amortization, and (ii) timing of recognition of gain on consolidation of subsidiary of $5.5 million which will not be recurring in the post-acquisition period. No effect has been given to other cost reductions or operating synergies. As a result, these pro forma results do not necessarily represent results that would have occurred if the acquisitions had taken place on the basis assumed above, nor are they indicative of the results of future combined operations (amounts in thousands except for earnings per share information).

The underlying asset in the Company’s put and call options is a forward contract. The Company’s swaps are agreements whereby a floating (or market or spot) price is exchanged for a fixed price over a specified period. The Company did not have any transfers of assets or liabilities between Level 1, Level 2 or Level 3 of the fair value measurement hierarchy during the period ended March 31, 2021 and 2020. Fair Value of Other Financial Instruments The estimated fair value of the Company’s other financial instruments was determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting this data to develop estimates of fair value. Consequently, the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. Restricted cash—short-term and long-term, trade receivables, due to IDT Corporation, other current assets and other current liabilities. At March 31, 2021 and December 31, 2020, the carrying amounts of these assets and liabilities approximated fair value. The fair value estimate for restricted cash—short-term and long-term was classified as Level 1. The carrying value of other current assets, due to IDT Corporation, and other current liabilities approximated fair value Other assets, revolving line of credit and notes payable. At March 31, 2021 and December 31, 2020, other assets included notes receivable. At March 31, 2021 The following table presents the items measured at fair value on a non-recurring basis: Level 1 Level 2 Level 3 Total (in thousands) March 31, 2021 Impairment of property and equipment $ — $ — $ — $ — December 31, 2020 Impairment of goodwill $ — $ — $ 1,397 $ 1,397 The primary non-recurring fair value estimates typically are in the context of business acquisitions (Note 5) which involve a combination of Level 2 and Level 3 inputs, goodwill impairment testing, which involves Level 3 inputs, and asset impairments (Note 8) which utilize Level 3 inputs. Concentration of Credit Risks The Company holds cash, cash equivalents, and restricted cash at several major financial institutions, which may exceed Federal Deposit Insurance Corporation insured limits. Historically, the Company has not experienced any losses due to such concentration of credit risk. The Company’s temporary cash investments policy is to limit the dollar amount of investments with any one financial institution and monitor the credit ratings of those institutions. While the Company may be exposed to credit losses due to the nonperformance of the holders of its deposits, the Company does not expect the settlement of these transactions to have a material effect on its results of operations, cash flows or financial condition. The following table summarizes the percentage of consolidated revenues from customers that equal or exceed 10.0% of the Company’s consolidated revenues in the period (no other single customer accounted for more than 10.0% of consolidated revenues in these periods): March 31, 2021 2020 Customer A na % 16.1 % na-less than 10.0% of consolidated revenue in the period At March 31, 2021 and December 31, 2020 no single customer accounted for 10.0% or greater of our consolidated trade receivables.

Derivative Instruments [Abstract]
Derivative Instruments	Note 7 — The primary risk managed by the Company using derivative instruments is commodity price risk, which is accounted for in accordance with Accounting Standards Codification 815 — Derivatives and Hedging. Natural gas and electricity put and call options and swaps are entered into as hedges against unfavorable fluctuations in market prices of natural gas and electricity. The Company does not apply hedge accounting to these options or swaps, therefore the changes in fair value are recorded in earnings. By using derivative instruments to mitigate exposures to changes in commodity prices, the Company exposes itself to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk. The Company minimizes the credit or repayment risk in derivative instruments by entering into transactions with high-quality counterparties. At March 31, 2021, GRE’s swaps and options were traded on the Intercontinental Exchange. GRE International's swaps and options were traded through counterparties. The summarized volume of GRE’s outstanding contracts and options at March 31, 2021 was as follows (MWh – Megawatt hour and Dth – Decatherm): Settlement Dates Volume Electricity (in MWH) Gas (in Dth) Second quarter 2021 99,116 166,600 Third quarter 2021 257,968 104,950 Fourth quarter 2021 45,800 103,650 First quarter 2022 — 100,700 Second quarter 2022 — 60,850 Third quarter 2022 — 24,740 Fourth quarter 2022 — 27,950 First quarter 2023 — 29,900 Second quarter 2023 — 12,850 Third quarter 2023 — 8,400 Fourth quarter 2023 — 8,750 First quarter 2024 — 4,700 Second quarter 2024 — 500 The fair value of outstanding derivative instruments recorded in the accompanying consolidated balance sheets were as follows: Asset Derivatives Balance Sheet Location March 31, 2021 December 31, 2020 (in thousands) Derivatives not designated or not qualifying as hedging instruments: Energy contracts and options 1 Other current assets $ 738 $ 1,338 Energy contracts and options Other assets 2 17 Total derivatives not designated or not qualifying as hedging instruments — $ 740 $ 1,355 Liability Derivatives Derivatives not designated or not qualifying as hedging instruments: Energy contracts and options 1 Other current liabilities $ 437 245 Energy contracts and options Other liabilities 45 41 Total derivatives not designated or not qualifying as hedging instruments — Liabilities $ 482 $ 286 ( 1 The Company classifies derivative assets and liabilities as current based on the cash flows expected to be incurred within the following 12 .

Incentives available under the Plan include stock options, stock appreciation rights, limited rights, deferred stock units, and restricted stock. The 2011 Plan, is scheduled to expire on October 24, 2021. On March 8, 2021, the Board of Directors adopted the Company 2021 Stock Option and Incentive Plan (the "2021 Plan"), subject to the approval of the Company's stockholders. The 2021 Plan, if approved by the Company's stockholders, will become effective and will replace the 2011 Plan as of May 12, 2021.

In February 2020, the Company granted certain employees and members of its Board of Directors an aggregate of 305,000 deferred stock units, which were subject to vesting in two tranches upon the achievement of a specified thirty-day average closing price of the Company's Class B common stock within specified periods of time (the "2020 market conditions") and the satisfaction of service-based vesting conditions. Each deferred stock unit entitled the grantee to receive, upon vesting, up to two shares of Class B common stock of the Company upon achievement of market conditions. The 2020 market conditions were not achieved and the awards expired in February 2021. There was no expense recognized for these awards. 18 In February 2021, the Company granted certain employees and members of its Board of Directors an aggregate of 305,000 deferred stock units which will vest in two tranches contingent upon the achievement of a specified thirty-day average closing price of the Company's Class B common stock within a specified period of time (the "2021 market conditions") and the satisfaction of service-based vesting conditions. Each deferred stock unit entitles the recipient to receive, upon vesting, up to two shares of Class B common stock of the Company depending on market conditions. The Company used a Monte Carlo simulation model to estimate the grant-date fair value of the awards. Assumptions and estimates utilized in the model include the risk-free interest rate, dividend yield, expected stock volatility based on a combination of the Company’s historical stock volatility. As of , there were approximately $5.3 million of total unrecognized stock-based compensation costs related to outstanding and unvested equity-based grants. These costs are expected to be recognized over a weighted-average period of approximately years.

Variable Interest Entity, Consolidated, Carrying Amount, Assets and Liability, Net [Abstract]
Variable Interest Entity	Note 13—Variable Interest Entity Citizens Choice Energy, LLC (“CCE”), is a REP that resells electricity and natural gas to residential and small business customers in the State of New York. The Company does not own any interest in CCE. Since 2011, the Company has provided CCE with substantially all of the cash required to fund its operations. The Company determined that it has the power to direct the activities of CCE that most significantly impact its economic performance and it has the obligation to absorb losses of CCE that could potentially be significant to CCE on a stand-alone basis. The Company therefore determined that it is the primary beneficiary of CCE, and as a result, the Company consolidates CCE within its GRE segment. The net income or loss incurred by CCE was attributed to noncontrolling interests in the accompanying consolidated statements of operations. The Company has an option to purchase 100% of the issued and outstanding limited liability company interests of CCE for one dollar plus the forgiveness of $0.5 million that the Company loaned to CCE in October 2015.

Earnings Per Share [Abstract]
Earnings Per Share	Note 15— (Loss) Earnings Per Share Basic earnings per share is computed by dividing net income or loss attributable to all classes of common stockholders of the Company by the weighted average number of shares of all classes of common stock outstanding during the applicable period. Diluted earnings per share is computed in the same manner as basic earnings per share, except that the number of shares is increased to include restricted stock still subject to risk of forfeiture and to assume exercise of potentially dilutive stock options using the treasury stock method, unless the effect of such increase is anti-dilutive. The weighted-average number of shares used in the calculation of basic and diluted earnings per share attributable to the Company’s common stockholders consists of the following: Three Months Ended March 31, 2021 2020 (in Basic weighted-average number of shares 26,004 26,108 Effect of dilutive securities: Stock options and warrants — 534 Non-vested restricted Class B common stock — 107 Diluted weighted-average number of shares 26,004 26,749 The following shares were excluded from the diluted earnings per share computations: 2021 2020 (in Shares underlying options and warrants 579 126 Non-vested restricted Class B common stock 71 — Non-vested deferred stock units 610 610 In three months ended March 31, 2021, the diluted loss per share computation equals basic loss per share because the Company has a net loss and the impact of the assumed exercise of stock options and warrants and the vesting of the restricted stock and deferred stock units would have been anti-dilutive. Stock options were excluded from the diluted earnings per share computation in the three months ended March 31, 2020 because the exercise prices of the stock options were greater than the average market prices of the Company's stock during the periods. Non-vested deferred stock units were excluded from the basic and diluted weighted average shares outstanding calculation because the market condition for vesting of those deferred stock units were not met as of March 31, 2021 and 2020.

Recently Issued Accounting Standards [Abstract]
Recently Issued Accounting Standards	Note 20—Recently Issued Accounting Standards In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments , that changes the impairment model for most financial assets and certain other instruments. For receivables, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowance for losses. For available-for-sale debt securities with unrealized losses, entities will measure credit losses in a manner similar to current practice, except the losses will be recognized as allowances instead of reductions in the amortized cost of the securities. In addition, an entity will have to disclose significantly more information about allowances, credit quality indicators and past due securities. The new provisions will be applied as a cumulative-effect adjustment to retained earnings. The Company will adopt the new standard on January 1, 2023. The Company is currently evaluating the requirements of this guidance and has not yet determined the impact of its adoption on the Company's consolidated financial statements.
