| Accounting Policies [Abstract] | |
| BASIS OF PRESENTATION | NOTE A: BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements include the accounts of New Concept Energy, Inc. and its majority-owned subsidiaries (collectively, “NCE” or the “Company”). All significant intercompany transactions and accounts have been eliminated. Certain reclassifications have been made to the prior year revenue and operating expense amounts in the statement of operations to conform to the current year presentation. The unaudited financial statements included herein have been prepared by the Company without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. The financial statements reflect all adjustments that are, in the opinion of management, necessary to fairly present such information. All such adjustments are of a normal recurring nature. Although the Company believes that the disclosures are adequate to make the information presented not misleading, certain information and footnote disclosures, including a description of significant accounting policies normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America, have been condensed or omitted pursuant to such rules and regulations. The Company’s ability to meet current cash obligations relies on cash received from current operations and the collection of notes receivable and interest thereon. The Company is evaluating business opportunities to provide both additional income and cash flow. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ending December 31, 2021. Operating results for the three month period ended March 31, 2022 are not necessarily indicative of the results that may be expected for any subsequent quarter or for the fiscal year ending December 31, 2022. |
