Mr. Obama has long been an advocate of renewable-energy credits, including a $3,000 tax rebate to retrofit homes that was part of the 2009 stimulus. His latest proposal includes more generous tax breaks and easier access to loans to fund retrofits, both intended to boost energy efficiency in commercial buildings by 20 percent by 2020.
HOME ENERGY EFFICIENCY IMPROVEMENT TAX CREDITS
Consumers who purchase and install specific products, such as energy-efficient windows, insulation, doors, roofs, and heating and cooling equipment in existing homes can receive a tax credit for 30% of the cost, up to $1,500, for improvements "placed in service" starting January 1, 2009, through December 31, 2010. See EnergyStar.gov's Federal Tax Credits for Energy Efficiency for a complete summary of energy efficiency tax credits available to consumers.
RESIDENTIAL RENEWABLE ENERGY TAX CREDITS
Consumers who install solar energy systems (including solar water heating and solar electric systems), small wind systems, geothermal heat pumps, and residential fuel cell and microturbine systems can receive a 30% tax credit for systems placed in service before December 31, 2016; the previous tax credit cap no longer applies.
