From the Document: "Since the 1970s, policymakers have increasingly used the tax code to promote energy policy goals. Long-term energy policy goals include providing a secure supply of energy, providing energy at a low cost, and ensuring that energy production and consumption is consistent with environmental objectives. A range of federal policies, including various research and development programs, mandates, and direct financial support such as tax incentives or loan guarantees, promotes various energy policy objectives. This report focuses on tax incentives that support the production of or investment in various energy resources."
