The claim that U.S. government energy subsidies favor nuclear energy over renewables (hydroelectric, wind, solar, geothermal) is not factual (DOE-EIA). From 1950-2006, total federal support chained to constant 2006 dollars (DOE-EIA) was $726 billion. Subsidies provided $529 billion for fossil fuels, $132 billion for renewables, and $65 billion for nuclear. Subsidies included tax relief ($326 billion), regulations ($142 billion), research and development ($135 billion), market activity, government service, and disbursements ($122 billion). The primary subsidy for nuclear energy has been research and development.
