The Energy Department's National Nuclear Security Administration would receive a 13 percent increase to $11.2 billion in 2011 to support the Obama administration's efforts to manage the nation's stockpile of nuclear weapons and achieve the president's goal of securing all vulnerable nuclear material in the world within four years.

Overall, the department's discretionary budget would increase more than 7 percent to $28.4 billion.

Energy programs outside of NNSA would increase less than 3 percent overall. The budget proposes $300 million for the new Advanced Projects Research Agency-Energy (ARPA-E), which would bankroll cutting-edge advanced energy technologies that will reduce the country's dependence on foreign energy imports and reduce greenhouse gas emissions. ARPA-E, which was modeled after the Defense Advanced Research Projects Agency, was created in 2007 but only recently funded with an initial $400 million from the Recovery Act.

Energy's budget proposes $5.1 billion for science research, an additional $217 million; $108 million above the $371 million approved this year to advance research into wind, solar and geothermal energy sources; and $500 million in credit subsidies that would support between $3 billion and $5 billion in energy-efficiency and renewable-energy projects.

The administration intends to cancel the $197 million program to build a nuclear waste repository at Yucca Mountain, Nev., and to continue efforts to develop a new nuclear waste management strategy. Another $50 million in savings would come from terminating the Ultra-Deepwater program for natural gas and petroleum exploration, while $71 million would be saved by canceling the planned expansion of the Strategic Petroleum Reserve.

The budget also proposes eliminating more than $2.7 billion in tax subsidies for oil, coal and gas industries, which the administration says would generate nearly $39 billion in revenue for the government during the next decade.
