Senate Appropriations Subcommittee on Energy and Water Ranking Member Lamar Alexander (R-TN) released an energy plan May 29 that calls for cheaper and cleaner energy sources, a focus on research and development rather than government mandates, and the continued use of the free market. Speaking at the Tennessee Valley Corridor Summit, Senator Alexander praised the role of research in the recent developments of advanced biofuels, carbon capture technology, electric vehicles, fusion, green buildings, nuclear waste management, small modular reactors, and solar power. He also advocated for doubling the $9 billion non-defense research and development annual spending.
