The National Nuclear Security Administration is making significant reductions in energy usage as NNSA meets the demands of the Stockpile Stewardship mission. Examples across the enterprise include:
- Supercomputers: Los Alamos National Laboratory has two supercomputers -- ranking second and fourth -- on the 2009 Green500 List , a project led by Virginia Tech computer scientists to rank supercomputer energy efficiency. Los Alamos's "Cerillos" supercomputer ranked second at more than 458 million flops per watt, while the lab's "Roadrunner," the world's fastest supercomputer for the past two years, came in fourth at nearly 445 million flops per watt.
- Pollution Prevention: The Y-12 National Security Complex earlier this year received a prestigious White House Closing the Circle award, which recognizes federal leadership in environmental sustainability. Y-12 was honored for its innovation on pollution prevention. Read the press release here. The program also was referenced in a Presidential Executive Order on federal leadership in environmental, energy and economic performance. Read the Executive Order here .

- Alternative Fuel: Displacement of petroleum fuel for the alternative fuel E-85 has been underway for several years. Gains in this area have earned the people leading the efforts recognition within the Administration and the Department.
- Fleet Management: NNSA professionals at Los Alamos National Laboratory were awarded NNSA Environmental Stewardship Awards for significant cost savings and for down-sizing/right-sizing the Laboratory vehicle fleet over the past two years.
- Energy Upgrades: Nevada Test Site professionals were awarded DOE Energy Management Awards for petroleum fuel displacement and energy-saving upgrades to lighting, air conditioning, associated controls, and the improved monitoring for these systems.
- Cool and White Roofs: For the past five years, the Federal/M&O/Building Technology Associates team from the Kansas City Site Office has been replacing, repairing, and upgrading the roofs of the National Security Enterprise using cool and white roof technology. This effort is a key component of the Facilities and Infrastructure Recapitalization Program.
- Energy Awareness: NNSA is constantly setting goals, measuring and tracking performance, and making sound strategic energy investment decisions.
