By the end of 2011, the nearly 16,500 Energy Star certified buildings across America have helped save nearly $2.3 billion in annual utility bills and prevent greenhouse gas emissions equal to emissions from the annual energy use of more than 1.5 million homes.
The U.S. Army is leading the march for renewable energy with a goal of 25 percent clean power by 2025. The Army Corps of Engineers has set up the Energy Initiatives Task Force (EITF) as of September, 2011 to help meet the deadline.

Producing hydrogen from non-fossil fuel sources is a problem that continues to elude many scientists but University of Delaware’s Erik Koepf thinks he may have discovered a solution.
Solving server overheating problems at datacenters will save massive amounts of wasted energy worldwide.
Survey of Over 100 Solar Manufacturers Reveal Current Environmental, Worker Safety, and Fiduciary Considerations
Achievable standard is in line with investments already being made and will inform the building of new plants moving forward.
Last March, the world watched closely as Japan struggled to contain a series of equipment failures, hydrogen explosions and releases of radioactive materials at the Fukushima Daiichi Nuclear Power Plant.
As scientists continue the hunt for energy sources that are safer, cleaner alternatives to fossil fuel, an ever-increasing amount of valuable farmland is being used to produce bioethanol, a source of transportation fuel. And while land-bound sources are renewable, economists and ecologists fear that diverting crops to produce fuel will limit food resources and drive up costs.
Genetic mutations to cellulose in plants could improve the conversion of cellulosic biomass into biofuels, according to a research team that included two Iowa State University chemists.
A Power Purchase Agreement enabled the Edwards Air Force Base to quickly gain solar power without any upfront costs.
There's more to the home energy conservation system designed by Queensland University of Technology industrial design graduate Erica Pozzey than meets the eye.
Marco Rosa-Clot, a professor at Florence University, has introduced his new project that addresses the limited-space concerns of photovoltaic panels: The Floating Tracking Cooling Concentrator (FTCC) System, which harnesses small basins and natural and artificial lakes to install PV plants.
Solvay has successfully commissioned its 1-megaWatt industrial demonstration fuel cell at the SolVin plant in Belgium.
Incandescent light bulbs are energy hogs, but many people prefer them for the cozy quality of light they emit.
The solar array is the first-ever installed on the office building and ReStore location for any Habitat for Humanity affiliate in the United States.
Research into biofuel crops, such as switchgrass and Miscanthus, has focused mainly on how to grow these crops and convert them into fuels. But many steps lead from the farm to the biorefinery, and each could help or hinder the growth of this new industry.
A $2 million award to the Center for Environmental Research and Technology at the University of California, Riverside's Bourns College of Engineering will fund a new project focused on powering electric vehicles from sunlight.
Scientists now have a way to more accurately compare how efficiently plants and photovoltaic cells convert sunlight into energy, thanks to findings by a research consortium that included a USDA scientist.
Ambitious solar initiative at Natick, Mass., schools and buildings will reduce energy consumption and provide educational and learning opportunities.
The tiny U.S. territory in the Caribbean has just 110,000 residents, all the beach, surf, wind and sun you'd ever want. The downside to this oasis is energy prices that are four to five times higher than are paid in the continental United States.
