The US Energy Information Administration (EIA) published an analysis of US government energy subsidies and R&D support in 2007, totaling $ billion – double the 1999 level. Of this, $ billion was related to electricity production, and $ billion of this was split between R&D and subsidies. Apart from transmission and distribution ($875 million), the balance was $ billion for R&D in anticipation of future benefits and $ billion in subsidies for present production. The $ billion for R&D comprised $922 million for nuclear, $522 million for coal and $108 million for renewables – which currently supply %, 49% and % (apart from hydro) of US power respectively. Nuclear R&D comprised $319 million for new nuclear plant design and proliferation-resistant fuel cycle, $350 million for clean-up of nuclear energy and research sites and $253 million for Idaho facilities and related management. Two-thirds of coal R&D was for 'clean coal' programs.
