Renewable Energy and Energy Efficiency Incentives: A Summary of Federal Programs [Updated November 15, 2019] [open pdf - 2MB]
From the Introduction: "Recognizing the impacts of depending on foreign energy sources, coupled with concerns over the volatility of prices driven by fluctuations in supply spurred by world events, prompted federal efforts to increase U.S. energy independence and reduce domestic consumption. As a major result, numerous programs have been established, focusing on energy efficiency, domestic conservation resources, and research that target the development of renewable sources of energy. Many of these programs have roots dating back more than 40 years and have been redesigned many times over that period. Many of the current programs have been reauthorized and redesigned periodically to meet changing economic conditions and national interests. [...] This report outlines current federal programs and provisions providing grants, loans, loan guarantees, tax credits, and other direct or indirect incentives for energy efficiency, energy conservation, and renewable energy RDD&D [research, design, development, and demonstration]. The programs are grouped by administering agency with references to applicable federal agency websites."
