Saw this report today from the GAO trying to summarize government funding renewable energy, broken down by department etc..
Governmentwide, 23 agencies and their 130 subagencies GAO reviewed implemented nearly 700 renewable energy initiatives in fiscal year 2010. The Departments of Defense (DOD), Agriculture (USDA), Energy (DOE), and the Interior were collectively responsible for almost 60 percent of all initiatives.
The initiatives supported a range of renewable energy sources, and the most commonly supported sources were bioenergy, solar, and wind. Also, the initiatives supported a range of public and private sector recipients, but the large majority provided support to the private sector. Many initiatives supported multiple renewable energy sources and types of recipients, while many others targeted support to one source or recipient. Agencies’ renewable energy efforts increased in recent years as a result of the provisions of the American Recovery and Reinvestment Act of 2009 and other factors, but the level of future efforts is less certain with the expiration of these provisions and budget constraints.
Across agencies, more than 80 percent of initiatives span four key federal roles—supporting research and development; using renewable energy in vehicle fleets and facilities; providing incentives for commercialization and deployment; and regulation, permitting, and ensuring compliance. Certain agencies led efforts in each federal role: DOE, DOD, and USDA for research and development; DOD, the General Services Administration, and DOE for fleets and facilities; Treasury and USDA for commercialization and deployment; and Interior and the Environmental Protection Agency for regulation, permitting, and compliance.
