The Government Accountability Office released two reports October 1 finding that federal initiatives to develop or deploy solar energy technologies and battery and storage technologies overlap but also have key differences and are guided by efforts to avoid duplication. The report Solar Energy: Federal Initiatives Overlap but Take Measures to Avoid Duplication, concludes that 65 solar-related initiatives in six federal agencies received $2.6 billion for the 1,506 solar projects in fiscal years 2010 and 2011. The office found similar results in a review of initiatives for its Batteries and Energy Storage: Federal Initiatives Supported Similar Technologies and Goals but Had Key Differences report.
