Continuing its campaign-year emphasis on a broad range of energy initiatives, the Obama administration has outlined a fresh roster of renewable-energy and energy-efficiency programs by the US military.
The White House said the moves were intended to improve the military's and the nation's energy security.
The Pentagon already had a statutory goal of meeting 25 percent of its faciility energy needs with renewable energy by 2025, and in his State of the Union Address in January President Obama said the Navy would develop 1 gigawatt (GW) of renewable energy on its installations by 2020.
Now the White House has upped the ante, vowing to deploy 3 GW of renewable energy - comprising solar, wind, biomass and geothermal - across all the services by 2025.
"These new steps build on President Obama's unwavering commitment to energy security for America's warfighters, and to a sustained, comprehensive strategy to ensure a secure energy future for all Americans," the White House said in a statement.
Perhaps anticipating a backlash from deficit hawks, the White House emphasized that these goals could be met "at no additional cost to taxpayers" by using a number of different financing tools. A recent example of the government's ability to do this was the switchover from coal to woody biomass at the U.S. Department of Energy's Savannah River Site.
The biomass plant was built using a federal financing device called an energy savings performance contract (ESPC), under which private companies finance, install and maintain new energy- and water-efficient equipment at federal facilities. The government pays no up-front costs and the company's investment is repaid over time by the agency from the cost savings generated by the new equipment.
