This book reviews the status of energy efficiency and renewable energy legislation introduced during the 110th Congress. Most action in the second session is focused on the FY2009 budget request, the Farm Bill (H.R. 2419), and the proposed Renewable Energy and Energy Conservation Tax Act (H.R. 5351). DOE's FY2009 budget request seeks $1,256.1 million for DOE's Energy Efficiency and Renewable Energy (EERE) programs, compared to FY2008 appropriations of $1,722.4 million for EERE. H.R. 5351 is similar to H.R. 2776. It would extend or re-establish several tax incentives that would support renewable electricity production, biofuels production, transportation efficiency and conservation, buildings efficiency, and equipment efficiency. The bill proposes to offset the cost of those incentives primarily by reducing two subsidies for oil and natural gas production.
