Accounting Policies [Abstract]
Basis of Presentation and Liquidity	NOTE 1— BASIS OF PRESENTATION AND LIQUIDITY The accompanying unaudited condensed consolidated financial statements of Acorn Energy, Inc. and its subsidiaries (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete consolidated financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three month period ended March 31, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016. All dollar amounts in the notes to the condensed consolidated financial statements are in thousands except for per share data. Certain reclassifications have been made to the Company’s condensed consolidated financial statements for the three month period ended March 31, 2015 to conform to the current period’s condensed consolidated financial statement presentation. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. The Company currently does not have sufficient cash flow for the next twelve months. As of March 31, 2016, the Company had less than $50 of non-escrow corporate cash and cash equivalents. On April 21, 2016, the Company closed on the sale of a portion of its interests in DSIT and received gross proceeds of $4,913 before escrow ($579), Israeli withholding taxes ($266) and fees (see Note 12 – Subsequent Events). On April 29, 2016, the Company repaid all principal ($2,000) and interest ($15) due to Leap Tide as well as $275 of principal and $41 of interest due to directors who had lent the Company money in the first quarter of 2016 (see Note 12 - Subsequent Events). Remaining cash after these debt repayments will be used to support the corporate cash needs of Acorn and its subsidiaries to the extent possible. Additional liquidity will be necessary to finance the operating activities of Acorn and the operations of its OmniMetrix subsidiary. The Company will continue to pursue sources of funding, which may include loans from related and/or non-related parties, a sale or partial sale of one or more of its companies, finding a strategic partner for one or more of the Company’s businesses or equity financings. There can be no assurance additional funding will be available at terms acceptable to the Company. There can be no assurance that we will be able to successfully utilize any of these possible sources to provide additional liquidity. If additional funding is not available in sufficient amounts, Acorn will not be able to fund its own corporate activities during the next twelve months, which could materially impact its ability to continue operations, and the Company may not be able to fund OmniMetrix as it has historically, which could materially impact its carrying value. As such, these factors raise substantial doubt as to the Company’s ability to continue as a going concern.

Recent Authoritative Guidance

Accounting Changes and Error Corrections [Abstract]
Recent Authoritative Guidance	NOTE 2—RECENT AUTHORITATIVE GUIDANCE In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-15 “Presentation of Financial Statements—Going Concern,” outlining management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern, along with the required disclosures. ASU 2014-15 is effective for the annual period ending after December 15, 2016 with early adoption permitted. The Company does not anticipate a material impact to our financial statements as a result of this change. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). ASU 2015-03 changes the presentation of debt issuance costs in financial statements, by requiring them to be presented in the balance sheet as a direct deduction from the related debt liability, rather than as an asset. Amortization of the costs is reported as interest expense. There is no change to the current guidance on the recognition and measurement of debt issuance costs. For public business entities, ASU 2015-03 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company does not expect ASU 2015-03 to have a material impact on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01 “Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,” which revises an entity’s accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation of certain fair value changes for financial liabilities measured at fair value. The ASU also amends certain disclosure requirements associated with the fair value of financial instruments. ASU 2016-01 is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017, with early adoption permitted under certain circumstances.” The Company is currently assessing the impact of ASU 2016-01 on its financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases, which is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018 with early adoption permitted. Under Accounting Standards Update 2016-02, lessees will be required to recognize for all leases at the commencement date a lease liability, which is a lessee’s obligation to make lease payments arising from a lease measured on a discounted basis, and a right-to-use asset, which is an asset that represents the lessee’s right to use or control the use of a specified asset for the lease term. The Company is currently evaluating the effect that the new guidance will have on its financial statements and related disclosures. In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which includes multiple provisions intended to simplify various aspects of the accounting for share-based payments, including treatment of excess tax benefits and forfeitures, as well as consideration of minimum statutory tax withholding requirements. The ASU will take effect for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016, with early application permitted in any interim or annual period. The Company is evaluating the future impact of this ASU on the consolidated financial statements. Other relevant recently issued accounting updates are not expected to have a material impact on the Company’s consolidated financial statements.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	NOTE 3— Discontinued Operations (a) GridSense On April 21, 2016, the Company announced that it has decided to cease operations of its GridSense subsidiary and initiate the liquidation of the GridSense assets. As a result of this decision, GridSense is being reported as a discontinued operation effective with the Company’s first quarter 2016 report. Following the decision to cease GridSense operations, the Company has written down all GridSense assets to their estimated realizable values and has accrued for estimated severance costs of $140 and lease commitments of $100 in GridSense’s first quarter results. The Company intends to sell its GridSense assets and is exploring ways to maximize value for creditors and other stakeholders, expecting that most of the proceeds from any sale of its assets will be used to pay creditors. It is uncertain whether there will be any proceeds available to the Company. Assets and liabilities related to the discontinued operations of GridSense are as follows: As at December 31, 2015 March 31, 2016 Cash and cash equivalents $ 48 $ 75 Other current assets and non-current assets 1,060 241 Total assets $ 1,108 $ 316 Short-term bank credit $ 138 $ 121 Accounts payable 950 978 Accrued payroll, payroll taxes and social benefits 186 303 Other current and non-current liabilities 572 614 Total liabilities $ 1,846 $ 2,016 GridSense had a working agreement with its bank to allow GridSense to borrow against 80% of certain accounts receivable balances up to $750 for a period of one year (to July 16, 2016) at an interest equal to 1.25% per month. At December 31, 2015, GridSense was utilizing approximately $138 of its accounts receivable line. At March 31, 2016, GridSense was utilizing approximately $121 of its accounts receivable line. GridSense granted a lien to its bank on substantially all of its assets other than intellectual property. GridSense further promised not to grant a lien on its intellectual property to any other party, nor commit to any such party to abstain from giving a lien. GridSense’s losses for the three months ended March 31, 2015 and 2016 are included in “Loss from discontinued operations, net of income taxes” in the Company’s Condensed Consolidated Statements of Operations. Summarized financial information for GridSense’s operations for the three months ended March 31, 2015 and 2016 are presented below: Three months ended March 31, 2015 2016 Revenues $ 908 $ 143 Gross profit (loss) 277 (30 ) Net loss $ (325 ) $ (1,386 ) (b) US Seismic Systems Inc. (“USSI”) In early 2015, the Company’s Board of Directors decided that it would no longer continue to fund USSI’s activities following the significant decline in oil prices which led to significantly reduced demand for USSI’s products. At that time, USSI effectively suspended operations and terminated substantially all employees. On September 28, 2015, the Board of Directors of USSI approved a motion to file a voluntary petition for protection under Chapter 7 of the United States Bankruptcy Code (a “Chapter 7 Bankruptcy”). Such filing was made on September 30, 2015. Under a Chapter 7 Bankruptcy, control of USSI no longer rests with the Company, but rather with a court-appointed trustee. Accordingly, effective September 30, 2015, the Company is no longer consolidating the assets, liabilities or operating results of USSI. USSI’s losses for the three months ended March 31, 2015 are included in “Loss from discontinued operations, net of income taxes” in the Company’s Condensed Consolidated Statements of Operations. Summarized financial information for USSI’s operations for the three months ended March 31, 2015 is presented below: Three months ended March 31, 2015 Revenues $ — Gross profit (90 ) Net loss (1,152 ) Net loss attributable to non-controlling interests 145 Net loss attributable to Acorn Energy Inc. $ (1,007 )

Restructuring and Related Activities [Abstract]
Restructuring and Related Charges	NOTE 4— RESTRUCTURING AND RELATED CHARGES In 2013, OmniMetrix restructured its operations to better align expenses with revenues following a change in management. The restructuring involved employee severance and termination benefits as well as a charge for a significant reduction in the utilization of its leased facility in Buford and a write-down of a majority of the remaining book value of leasehold improvements associated with the leased facility. At December 31, 2015, $204 of lease payments associated with the reduced utilization of leased facilities remained unpaid. During the three months ended March 31, 2016, OmniMetrix paid $11 of this liability. The total remaining accrued restructuring balance of $193 is expected to be paid in full by December 31, 2019 and is included in Other current liabilities ($46) and Other liabilities ($147) in the Company’s condensed consolidated balance sheets.

In March 2016, the Company borrowed, on similar terms, an additional $75 from another director. Upon maturity, the Company was to pay to each director a single payment equal to 115% of the amounts borrowed under the promissory notes. Under the terms of each promissory note, at maturity, the lender could elect to convert the entire amount due under the promissory note into Common Stock of the Company at a conversion price equal to the closing price of the Company’s Common Stock on the trading day immediately preceding the maturity date of the loan. The lender of the most recent loan has agreed to lend the Company up to an additional $75 upon request by the Company under similar terms. All the above notes were repaid in full or converted to the Company’s common shares following the closing of the DSIT Transaction – see Note 12 - Subsequent Events.

Segment Reporting [Abstract]
Segment Reporting	NOTE 11—SEGMENT REPORTING The Company currently operates in two reportable operating segments: ● Energy & Security Sonar Solutions. The Company provides sonar and acoustic related solutions for energy, defense and commercial markets with a focus on underwater site security for strategic energy installations and other advanced acoustic systems and real-time embedded hardware and software development and production through its DSIT Solutions Ltd. (“DSIT”) subsidiary. (See below) ● Power Generator Monitoring (“PGM”) (formerly known as Machine-to-Machine Critical Asset Monitoring & Control). The PGM segment provides wireless remote monitoring and control systems and services for critical assets as well as Internet of Things applications. These activities are performed through the Company’s OmniMetrix subsidiary. Other operations include certain IT activities (protocol management software for cancer patients and billing software) and outsourced consulting activities performed by the Company’s DSIT subsidiary as well as Corrosion Protection Monitoring activities performed by the Company’s OmniMetrix subsidiary (for remote monitoring of cathodic protection systems on gas pipelines for gas utilities and pipeline companies) that do not meet the quantitative thresholds under applicable accounting principles. Previously, the Company reported GridSense’s activities in its Smart Grid Distribution Automation segment which developed and produced fiber optic sensing systems for the energy and security markets. With the suspension of operations at GridSense (see Note 3(a)), its activities are reflected as discontinued operations. Following the closing of the DSIT Transaction (see Note 12 – Subsequent Events), beginning with the Company’s second quarter 2016 report, the Company will no longer be consolidating the results of DSIT, but will be reporting on its investment in DSIT on the equity method. Accordingly, beginning with the Company’s second quarter 2016 report, the Company will no longer be reporting on the results of its Energy & Security Sonar Solutions segment.

Subsequent Events [Abstract]
Subsequent Events	NOTE 12 — SUBSEQUENT EVENTS Sale of interest in DSIT On April 21, 2016, the Company closed on a transaction (the “DSIT Transaction”) initially entered into on January 28, 2016 for the sale of a 50% interest in its DSIT Solutions, Ltd. business to Rafael Advanced Defense Systems Ltd., a major Israeli defense company. At closing, Acorn received gross proceeds of $4,913 before escrow, fees and taxes. From the gross proceeds, Acorn deposited approximately $579 to satisfy the escrow requirements in the sale. The Company will be able access those funds, net of any disbursements, in October 2017. Acorn also paid an Israeli withholding tax of approximately $266. Acorn is also eligible to receive its pro-rata share of a $1,000 earn-out over a three-year period. Following the sale, Acorn owns approximately 41.2% of DSIT. Repayment of Leap Tide Loan On August 13, 2015, the Company executed a Loan and Security Agreement with Leap Tide Capital Partners III, LLC (“Leap Tide”), pursuant to which the Company borrowed $2,000 from Leap Tide (the “LT Loan”). Jan H. Loeb, the Company’s new President and CEO (see Note 8) is the Manager of Leap Tide. Principal and accrued interest was due and payable on August 13, 2016. Interest accrued and was payable quarterly at a rate of 10% per annum. On April 29, 2016, following the receipt of the net proceeds from the DSIT Transaction, the Company repaid in full the $2,000 of principal and all accrued interest in full satisfaction of the cash due to Leap Tide under the LT Loan. In addition to the interest payable in cash described above, Leap Tide received 850,000 shares of the Company’s common stock (the “Initial Shares”) at the closing and was entitled to vested rights to receive 179,167 additional shares of the Company’s common stock (each vested right to receive one share, a “Vested Share Right”) per month for each full month that the full principal amount of the LT Loan was outstanding. The number of Vested Share Rights that accrued in a given month was prorated to the extent less than the full principal amount was outstanding and/or for any partial month in which no principal amount was outstanding. Leap Tide is entitled to receive the Company’s common stock underlying its Vested Share Rights after the expiration of the Cash Settlement Period (defined below). Through April 29, 2016, Leap Tide earned 1,531,396 Vested Share Rights. Under the terms of the LT Loan, the Company may on or prior to 30 days after the repayment of the LT Loan (such 30-day period being referred to herein as the “Cash Settlement Period”) repurchase any or all Initial Shares and settle any or all Vested Share Rights accrued under the LT Loan for cash in lieu of stock. The cash repurchase/settlement price would be $0.30 for each Initial Share so repurchased and each Vested Share Right so settled. The Company does not expect to repurchase any of the Initial Shares or settle any of the accrued Vested Share Rights for cash. Repayment of Loans from Directors On April 29, 2016, following the receipt of the net proceeds from the DSIT Transaction, the Company repaid in full $275 ($200 from one director and $75 from a another director) under promissory notes plus interest equal to 15% of the amounts borrowed under the promissory notes. In addition, a third director who had lent the Company $100 under similar terms, elected to convert the principal and $15 of interest due into Common Stock of the Company. In accordance with the terms of the promissory note, the director received 465,587 shares of Common Stock of the Company.
