ORGANIZATION AND DESCRIPTION OF BUSINESS	3 Months Ended
ORGANIZATION AND DESCRIPTION OF BUSINESS	Mar. 31, 2015
ORGANIZATION AND DESCRIPTION OF BUSINESS [Text Block]	NOTE 1 - ORGANIZATION AND DESCRIPTION OF BUSINESS

	U.S. Geothermal Inc. (“the Company”) was incorporated on March 10, 2000 in the State of Delaware. U.S. Geothermal Inc. – Idaho was formed in February 2002, and is the primary subsidiary through which the Company conducts its operations. The Company constructs, manages and operates power plants that utilize geothermal resources to produce energy. The Company’s operations have been, primarily, focused in the Western United States of America.

	Basis of Presentation

	These unaudited interim consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. In our opinion, the unaudited consolidated financial statements include all material adjustments, all of which are of a normal and recurring nature, necessary to present fairly our financial position as of March 31, 2015 and our operating results and cash flows for the three months ended March 31, 2015 and 2014. The accompanying financial information as of December 31, 2014 is derived from audited financial statements. Interim results are not necessarily indicative of results for a full year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2014.

	The Company consolidates subsidiaries that it controls (more-than- 50% owned) and entities over which control is achieved through means other than voting rights. These consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, as well as three controlling interests. The accounts of the following companies are consolidated in these financial statements:

		i)	U.S. Geothermal Inc. (incorporated in the State of Delaware);
		ii)	U.S. Geothermal Inc. (incorporated in the State of Idaho);
		iii)	U.S. Geothermal Services, LLC (organized in the State of Delaware);
		iv)	Nevada USG Holdings, LLC (organized in the State of Delaware);

	All intercompany transactions are eliminated upon consolidation.

	In cases where the Company owns a majority interest in an entity but does not own 100% of the interest in the entity, it recognizes a non-controlling interest attributed to the interest controlled by outside third parties. The Company will recognize 100% of the assets and liabilities of the entity, and disclose the non-controlling interest. The statements of comprehensive income will consolidate the subsidiary’s full operations, and will separately disclose the elimination of the non-controlling interest’s allocation of profits and losses.

SUMMARY_OF_SIGNIFICANT_ACCOUNT

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	3 Months Ended
	Mar. 31, 2015
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Text Block]	NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

	Cash and Cash Equivalents

	The Company considers all unrestricted cash, short-term deposits, and other investments with original maturities of no more than ninety days when acquired to be cash and cash equivalents.

	Trade Accounts Receivable Allowance for Doubtful Accounts

	Management estimates the amount of trade accounts receivable that may not be collectible and records an allowance for doubtful accounts. The allowance is an estimate based upon aging of receivable balances, historical collection experience, and the periodic credit evaluations of our customers’ financial condition. Receivable balances are written off when we determine that the balance is uncollectible. As of March 31, 2015 and December 31, 2014, there were no balances that were over 90 days past due and no balance in allowance for doubtful accounts was recognized.

	Concentration of Credit Risk

	The Company’s cash and cash equivalents, including restricted cash, consisted of commercial bank deposits, money market accounts, and petty cash. Cash deposits are held in commercial banks in Boise, Idaho and Portland, Oregon. Deposits are guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 per legal entity. At March 31, 2015, the Company’s total cash balance, excluding money market funds, was $3,869,559, and bank deposits amounted to $3,967,574. The primary difference was due to outstanding checks and deposits. Of the bank deposits, $2,480,347 was not covered by or was in excess of FDIC insurance guaranteed limits. At March 31, 2015, the Company’s money market funds invested, primarily, in government backed securities totaled $30,653,529 and were not subject to deposit insurance.

	Property, Plant and Equipment

	Property, plant and equipment, including assets under capital lease, are recorded at historical cost. Costs of acquisition of geothermal properties are capitalized in the period of acquisition. Major improvements that significantly increase the useful lives and/or capabilities of the assets are capitalized. A primary factor in determining whether to capitalize construction type costs is the stage of the potential project’s development. Once a project is determined to be commercially viable, all costs directly associated with the development and construction of the project are capitalized. Until that time, all development costs are expensed. A commercially viable project will have, among other factors, a reservoir discovery well or other significant geothermal surface anomaly, a power transmission path that is identified and available, and an electricity off-taker identified. A valid reservoir discovery is generally defined when a test well has been substantially completed that indicates the presence of a geothermal reservoir that has a high probability of possessing the necessary temperatures, permeability, and flow rates. After a valid discovery has been made, the project enters the development stage. Generally, all costs incurred during the development stage are capitalized and tracked on an individual project basis. If a geothermal project is abandoned, the associated costs that have been capitalized are charged to expense in the year of abandonment. Expenditures for repairs and maintenance are charged to expense as incurred. Interest costs incurred during the construction period of defined major projects from debt that is specifically incurred for those projects are capitalized. Funds received from grants associated with capital projects reduce the cost of the asset directly associated with the individual grants. The offset of the cost of the asset associated with grant proceeds is recorded in the period when the requirements of the grant are substantially complete and the amount can be reasonably estimated.

	Direct labor costs, incurred for specific major projects expected to have long-term benefits will be capitalized. Direct labor costs subject to capitalization include employee salaries, as well as, related payroll taxes and benefits. With respect to the allocation of salaries to projects, salaries are allocated based on the percentage of hours that our key managers, engineers and scientists work on each project and are invoiced to the project each month. These individuals track their time worked at each project. Major projects are, generally, defined as projects expected to exceed $500,000. Direct labor includes all of the time incurred by employees directly involved with construction and development activities. General and/or indirect management time and time spent evaluating the feasibility of potential projects is expensed when incurred. Employee training time is expensed when incurred.

	Depreciation is calculated on a straight-line basis over the estimated useful life of the asset. Where appropriate, terms of property rights and revenue contracts can influence the determination of estimated useful lives. Estimated useful lives in years by major asset categories are summarized as follows:

		Estimated Useful
	Asset Categories	Lives in Years

	Furniture, vehicle and other equipment	3 to 5
	Power plant, buildings and improvements	3 to 30
	Wells	30
	Well pumps and components	5 to 15
	Pipelines	30
	Transmission lines	30

	Stock Compensation

	The Company accounts for stock based compensation by recording the estimated fair value of stock-based awards granted as compensation expense over the vesting period, net of estimated forfeitures. The fair value of restricted stock awards is determined based on the number of shares granted and the quoted price of the Company’s common stock on the date of grant. The fair value of stock option awards is estimated at the grant date as calculated by the Black-Scholes-Merton option pricing model. Stock-based compensation expense is attributed to earnings for stock options and restricted stock on the straight-line method. The Company estimates forfeitures of stock-based awards based on historical experience and expected future activity.

	Earnings Per Share

	Basic income or loss per share is computed using the weighted average number of common shares outstanding during the period, and excludes any dilutive effects of common stock equivalent shares, such as options and restricted stock awards. Restricted stock awards (“RSAs”) are considered outstanding and included in the computation of basic income or loss per share when underlying restrictions expire and the awards are no longer forfeitable. Diluted income per share is computed using the weighted average number of common shares outstanding and common stock equivalent shares outstanding during the period using the treasury stock method. Common stock equivalent shares are excluded from the computation if their effect is anti-dilutive. In a period where we are in a net loss position, the diluted loss per share is computed using the basic share count.

	Foreign Currency Translation

	The Company’s functional currency is the U.S. dollar. Monetary items are converted into U.S. dollars at the rate prevailing at the balance sheet date. Resulting gains and losses are generally included in determining net income for the period in which exchange rates change.

	Revenue

	Revenue Recognition

	Energy Sales

	The energy sales revenue is recognized when the electrical power generated by the Company’s power plants is delivered to the customer who is reasonably assured to be able to pay under the terms defined by the Power Purchase Agreements (“PPAs”).

	Renewable Energy Credits (“RECs”)

	Currently, the Company operates three plants that produce renewable energy that creates a right to a REC. The Company earns one REC for each megawatt hour produced from the geothermal power plant. The Company considers the RECs to be an inventory item held for sale, and outputs that are an economic benefit obtained directly through the operation of the plants. The Company does not currently hold any RECs for our own use. Revenues from RECs sales are recognized when the Company has met the terms and conditions of certain energy sales agreements with a financially capable buyer. At Raft River Energy I LLC, each REC is certified by the Western Electric Coordinating Council and sold under a REC Purchase and Sales Agreement to Holy Cross Energy. At San Emidio and Neal Hot Springs, the RECs are owned by our customer and are bundled with energy sales. At all three plants, title for the RECs pass during the same month as energy sales. As a result, costs associated with the sale of RECs are not segregated on the statement of operations.

	Revenue Source

	All of the Company’s operating revenues (energy sales and energy credit sales) originate from energy production from its interests in geothermal power plants located in the states of Idaho, Oregon and Nevada.

	Recent Accounting Pronouncements

	Management has considered all recent accounting pronouncements. The following pronouncements were deemed applicable to our financial statements:

Consolidation

In February 2015, FASB issued Accounting Standards Update No. 2015-02 (“Update 2015-02”), Amendments to the Consolidation Analysis, Consolidation (Topic 810). Update 2015-02 provides modifications to the evaluation of variable interest entities that may impact consolidation of reporting entities. Update 2015-02 is effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The Company currently consolidates variable interest entities and may create or acquire variable interest entities for future endeavors. Management is still evaluating the possible impact this Update may have on the financial presentation of the Company’s consolidated financial statements.

Presentation of Debt Issuance Costs

In April 2015, FASB issued Accounting Standards Update No. 2015-03 (“Update 2015-03”), Simplifying the Presentation of Debt Issuance Costs, Interest-Imputation of Interest (Subtopic 835-30). Update 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. For public business entities, Update 2015-03 is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. Management is still evaluating the impact and the timing of adoption of this Update.

	The well bonding requirements ensure that the Company has sufficient financial resources to construct, operate and maintain geothermal wells while safeguarding subsurface, surface and atmospheric resources from unreasonable degradation, and to protect ground water aquifers and surface water sources from contamination. Other future costs of environmental remediation cannot be reasonably estimated and have not been recorded. The debt service reserves are required to provide assurance that the Company will have sufficient funds to meet its debt payment obligations for the terms specified by the loan agreements. The maintenance and capital expenditure reserves are required by the lending entities to ensure that funds are available to acquire and maintain critical components of power plants and related supporting structures to enable the plants to operate according to expectations. Except for the PPA Security Bond, all of the restricted funds consisted of cash deposits or money market accounts held in commercial banks. Portions of the cash deposits are subject to FDIC insurance. See note 2 for details. The PPA Security Bond is held by the power purchaser. All of the reserve accounts were considered to be fully funded at March 31, 2015 and December 31, 2014.

	U.S. Department of Energy
	On August 31, 2011, USG Oregon LLC (“USG Oregon”), a subsidiary of the Company, completed the first funding drawdown associated with the U.S. Department of Energy (“DOE”) $96.8 million loan guarantee (“Loan Guarantee”) to construct its power plant at Neal Hot Springs in Eastern Oregon (the “Project”). All loan advances covered by the Loan Guarantee have been made under the Future Advance Promissory Note (the “Note”) dated February 23, 2011. Upon the occurrence and continuation of an event of default under the transaction documents, all amounts payable under the Note may be accelerated. In connection with the Loan Guarantee, the DOE has been granted a security interest in all of the equity interests of USG Oregon, as well as in the assets of USG Oregon, including a mortgage on real property interests relating to the Project site. No additional advances are allowed under the terms of the loan. A total of 13 draws were taken and each individual draw or tranche is considered to be a separate loan. The loan principal is scheduled to be paid over 21.5 years with semi-annual installments including interest calculated at an aggregate fixed interest rate of 2.598%. The principal payment amounts are calculated on a straight-line basis according to the life of the loans and the original loan principal amounts. The principal portion of the aggregate loan payment is adjusted as individual tranches are extinguished. The principal payments started at $1,709,963 on February 10, 2014 and are scheduled to be reduced to $1,626,251 on February 10, 2017 and continue through February 12, 2035.

STOCK BASED COMPENSATION	Mar. 31, 2015
STOCK BASED COMPENSATION [Text Block]	NOTE 7 - STOCK BASED COMPENSATION

	The Company has a stock incentive plan (the “Stock Incentive Plan”) for the purpose of attracting and motivating directors, officers, employees and consultants of the Company and advancing the interests of the Company. The Stock Incentive Plan is a 15% rolling plan approved by shareholders in September 2013, whereby the Company can grant options to the extent of 15% of the current outstanding common shares. Under the plan, all forfeited and exercised options can be replaced with new offerings. As of March 31, 2015, the Company can issue stock option grants totaling up to 16,059,454 shares. Options are typically granted for a term of up to five years from the date of grant. Stock options granted generally vest over a period of eighteen months, with 25% vesting on the date of grant and 25% vesting every six months thereafter. The Company recognizes compensation expense using the straight-line method of amortization. Historically, the Company has issued new shares to satisfy exercises of stock options and the Company expects to issue new shares to satisfy any future exercises of stock options.

	The following table reflects the summary of stock options outstanding at December 31, 2014 and changes for the three months ended March 31, 2014:

					Weighted
					Average		Weighted
		Number of			Exercise		Average		Aggregate
		shares under			Price Per		Fair		Intrinsic

	Balance outstanding, March 31, 2015	11,313,500		$	0.61	$	0.36	$	4,016,557

	The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model using the assumptions noted in the following table. Expected volatilities are based on historical volatility of the Company’s stock. The Company uses historical data to estimate option volatility within the Black-Scholes model. The expected term of options granted represents the period of time that options granted are expected to be outstanding, based upon past experience and future estimates and includes data from the Plan. The risk-free rate for periods within the expected term of the option is based upon the U.S. Treasury yield curve in effect at the time of grant. The Company currently does not foresee the payment of dividends in the near term.



	Changes in the subjective input assumptions can materially affect the fair value estimate and, therefore, the existing models do not necessarily provide a reliable measure of the fair value of the Company’s stock options.

	As of March 31, 2015, there was $288,721 of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under the Plan. That cost is expected to be recognized over a weighted-average period of 1.5 years.

	Stock Compensation Plan (Restricted Shares )

	On April 19, 2013, the Company granted an officer and director 300,000 common shares valued at $0.35 per share, which were distributed at the end of a one-year vesting period. The recipient meets the vesting requirements by maintaining employment and good standing with the Company through the vesting period. After vesting, there are no restrictions on the shares. These shares were issued in July 2013 to the recipient and held by the Company until vested. The total fair value of options at the grant date was $105,000.

	On April 2, 2014, the Company issued 559,122 shares of Company stock at a price of $0.74 that fully vest on April 2, 2015 to its employees and directors. The total fair value is $413,750 and the recognized cost through March 31, 2015.

	Stock Purchase Warrants

	At March 31, 2015, the outstanding broker warrants and share purchase warrants consisted of the following:

					Broker

FAIR VALUE MEASUREMENT [Text Block]

NOTE 8 – FAIR VALUE MEASUREMENT

Current U.S. generally accepted accounting principles establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement).

The three levels of the fair value hierarchy are as follows:

Level 1 – Quoted prices are available in active markets for identical assets or liabilities.

Level 2 – Directly or indirectly market based inputs or observable inputs used in models or other valuation methodologies.

Level 3 – Unobservable inputs that are no corroborated by market data. The inputs require significant management judgement or estimation.

The following table discloses by level within the fair value hierarchy the Company’s assets and liabilities measured and reported on its Consolidated Balance Sheet as at fair value on a recurring basis:

	Gerlach Geothermal LLC
	On April 28, 2008, the Company formed Gerlach Geothermal, LLC (“Gerlach”) with our partner, Gerlach Green Energy, LLC (“GGE”). The purpose of the joint venture is the exploration of the Gerlach geothermal system, which is located in northwestern Nevada, near the town of Gerlach. Based upon the terms of the members’ agreement, the Company owns a 60% interest and GGE owns a 40% interest in Gerlach Geothermal, LLC. The agreement gives GGE an option to maintain its 40% ownership interest as additional capital contributions are required. If GGE dilutes to below a 10% interest, their ownership position in the joint venture would be converted to a 10% net profits interest. The Company has contributed $757,190 in cash and $300,000 for a geothermal lease and mineral rights; and the GGE has contributed $704,460 of geothermal lease, mineral rights and exploration data. During the first three quarters of the current year, contributions were made to Gerlach by the Company and GGE that totaled $11,040 and $7,360 ; respectively. These contributions maintained the existing ownership interests of the two partners in Gerlach. During the fourth quarter of the year ended December 31, 2014, the Company contributed $400,000 for the project’s drilling costs that were not proportionally matched by GGE. These contributions effectively reduced GGE’s ownership interest to 32.65%, and increased the Company’s interest to 67.35% as of December 31, 2014.

	The consolidated financial statements reflect 100% of the assets and liabilities of Gerlach, and report the current non-controlling interest of GGE. The full results of Gerlach’s operations are reflected in the statement of operations with the elimination of the non-controlling interest identified.

Cash and Cash Equivalents [Policy Text Block]	Cash and Cash Equivalents

	The Company considers all unrestricted cash, short-term deposits, and other investments with original maturities of no more than ninety days when acquired to be cash and cash equivalents.
Trade Accounts Receivable Allowance for Doubtful Accounts [Policy Text Block]	Trade Accounts Receivable Allowance for Doubtful Accounts

	Management estimates the amount of trade accounts receivable that may not be collectible and records an allowance for doubtful accounts. The allowance is an estimate based upon aging of receivable balances, historical collection experience, and the periodic credit evaluations of our customers’ financial condition. Receivable balances are written off when we determine that the balance is uncollectible. As of March 31, 2015 and December 31, 2014, there were no balances that were over 90 days past due and no balance in allowance for doubtful accounts was recognized.
Concentration of Credit Risk [Policy Text Block]	Concentration of Credit Risk

	The Company’s cash and cash equivalents, including restricted cash, consisted of commercial bank deposits, money market accounts, and petty cash. Cash deposits are held in commercial banks in Boise, Idaho and Portland, Oregon. Deposits are guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 per legal entity. At March 31, 2015, the Company’s total cash balance, excluding money market funds, was $3,869,559, and bank deposits amounted to $3,967,574. The primary difference was due to outstanding checks and deposits. Of the bank deposits, $2,480,347 was not covered by or was in excess of FDIC insurance guaranteed limits. At March 31, 2015, the Company’s money market funds invested, primarily, in government backed securities totaled $30,653,529 and were not subject to deposit insurance.
Property, Plant and Equipment [Policy Text Block]	Property, Plant and Equipment

	Property, plant and equipment, including assets under capital lease, are recorded at historical cost. Costs of acquisition of geothermal properties are capitalized in the period of acquisition. Major improvements that significantly increase the useful lives and/or capabilities of the assets are capitalized. A primary factor in determining whether to capitalize construction type costs is the stage of the potential project’s development. Once a project is determined to be commercially viable, all costs directly associated with the development and construction of the project are capitalized. Until that time, all development costs are expensed. A commercially viable project will have, among other factors, a reservoir discovery well or other significant geothermal surface anomaly, a power transmission path that is identified and available, and an electricity off-taker identified. A valid reservoir discovery is generally defined when a test well has been substantially completed that indicates the presence of a geothermal reservoir that has a high probability of possessing the necessary temperatures, permeability, and flow rates. After a valid discovery has been made, the project enters the development stage. Generally, all costs incurred during the development stage are capitalized and tracked on an individual project basis. If a geothermal project is abandoned, the associated costs that have been capitalized are charged to expense in the year of abandonment. Expenditures for repairs and maintenance are charged to expense as incurred. Interest costs incurred during the construction period of defined major projects from debt that is specifically incurred for those projects are capitalized. Funds received from grants associated with capital projects reduce the cost of the asset directly associated with the individual grants. The offset of the cost of the asset associated with grant proceeds is recorded in the period when the requirements of the grant are substantially complete and the amount can be reasonably estimated.

	Direct labor costs, incurred for specific major projects expected to have long-term benefits will be capitalized. Direct labor costs subject to capitalization include employee salaries, as well as, related payroll taxes and benefits. With respect to the allocation of salaries to projects, salaries are allocated based on the percentage of hours that our key managers, engineers and scientists work on each project and are invoiced to the project each month. These individuals track their time worked at each project. Major projects are, generally, defined as projects expected to exceed $500,000. Direct labor includes all of the time incurred by employees directly involved with construction and development activities. General and/or indirect management time and time spent evaluating the feasibility of potential projects is expensed when incurred. Employee training time is expensed when incurred.

	Depreciation is calculated on a straight-line basis over the estimated useful life of the asset. Where appropriate, terms of property rights and revenue contracts can influence the determination of estimated useful lives. Estimated useful lives in years by major asset categories are summarized as follows:

		Estimated Useful
	Asset Categories	Lives in Years

	Furniture, vehicle and other equipment	3 to 5
	Power plant, buildings and improvements	3 to 30
	Wells	30
	Well pumps and components	5 to 15
	Pipelines	30
	Transmission lines	30
Stock Compensation [Policy Text Block]	Stock Compensation

	The Company accounts for stock based compensation by recording the estimated fair value of stock-based awards granted as compensation expense over the vesting period, net of estimated forfeitures. The fair value of restricted stock awards is determined based on the number of shares granted and the quoted price of the Company’s common stock on the date of grant. The fair value of stock option awards is estimated at the grant date as calculated by the Black-Scholes-Merton option pricing model. Stock-based compensation expense is attributed to earnings for stock options and restricted stock on the straight-line method. The Company estimates forfeitures of stock-based awards based on historical experience and expected future activity.
Earnings Per Share [Policy Text Block]	Earnings Per Share

	Basic income or loss per share is computed using the weighted average number of common shares outstanding during the period, and excludes any dilutive effects of common stock equivalent shares, such as options and restricted stock awards. Restricted stock awards (“RSAs”) are considered outstanding and included in the computation of basic income or loss per share when underlying restrictions expire and the awards are no longer forfeitable. Diluted income per share is computed using the weighted average number of common shares outstanding and common stock equivalent shares outstanding during the period using the treasury stock method. Common stock equivalent shares are excluded from the computation if their effect is anti-dilutive. In a period where we are in a net loss position, the diluted loss per share is computed using the basic share count.
Foreign Currency Translation [Policy Text Block]	Foreign Currency Translation

	The Company’s functional currency is the U.S. dollar. Monetary items are converted into U.S. dollars at the rate prevailing at the balance sheet date. Resulting gains and losses are generally included in determining net income for the period in which exchange rates change.
Revenue [Policy Text Block]	Revenue

	Revenue Recognition

	Energy Sales

	The energy sales revenue is recognized when the electrical power generated by the Company’s power plants is delivered to the customer who is reasonably assured to be able to pay under the terms defined by the Power Purchase Agreements (“PPAs”).

	Renewable Energy Credits (“RECs”)

	Currently, the Company operates three plants that produce renewable energy that creates a right to a REC. The Company earns one REC for each megawatt hour produced from the geothermal power plant. The Company considers the RECs to be an inventory item held for sale, and outputs that are an economic benefit obtained directly through the operation of the plants. The Company does not currently hold any RECs for our own use. Revenues from RECs sales are recognized when the Company has met the terms and conditions of certain energy sales agreements with a financially capable buyer. At Raft River Energy I LLC, each REC is certified by the Western Electric Coordinating Council and sold under a REC Purchase and Sales Agreement to Holy Cross Energy. At San Emidio and Neal Hot Springs, the RECs are owned by our customer and are bundled with energy sales. At all three plants, title for the RECs pass during the same month as energy sales. As a result, costs associated with the sale of RECs are not segregated on the statement of operations.

	Revenue Source

	All of the Company’s operating revenues (energy sales and energy credit sales) originate from energy production from its interests in geothermal power plants located in the states of Idaho, Oregon and Nevada.
Recent Accounting Pronouncements [Policy Text Block]	Recent Accounting Pronouncements

	Management has considered all recent accounting pronouncements. The following pronouncements were deemed applicable to our financial statements:

	Consolidation

	In February 2015, FASB issued Accounting Standards Update No. 2015-02 (“Update 2015-02”), Amendments to the Consolidation Analysis, Consolidation (Topic 810). Update 2015-02 provides modifications to the evaluation of variable interest entities that may impact consolidation of reporting entities. Update 2015-02 is effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The Company currently consolidates variable interest entities and may create or acquire variable interest entities for future endeavors. Management is still evaluating the possible impact this Update may have on the financial presentation of the Company’s consolidated financial statements.

	Presentation of Debt Issuance Costs

	In April 2015, FASB issued Accounting Standards Update No. 2015-03 (“Update 2015-03”), Simplifying the Presentation of Debt Issuance Costs, Interest-Imputation of Interest (Subtopic 835-30). Update 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. For public business entities, Update 2015-03 is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. Management is still evaluating the impact and the timing of adoption of this Update.
