Happening now: the competition finals for Year One of EcoCAR 2 in Los Angeles, California.

According to a new report from Pacific Northwest National Lab, commercial building owners could save an average 38 percent on their heating and cooling bills just by installing a few new controls onto their HVAC systems.

Imagine being able to charge an electric vehicle without ever having to plug-in. A new funding opportunity from the Energy Department seeks to accomplish just that.

The city of North Pole, Alaska, is hoping to use $100,000 in Energy Efficiency and Conservation Block Grant funds to improve the energy efficiency of several key city facilities.

Diesel engines can be more than twice as fuel efficient as gasoline engines, but they also produce more pollution like particulate matter and nitrogen oxide. A team of researchers at Argonne are combining the efficiency of diesel with the cleanliness of gasoline.

Teams at two of the Energy Department's laboratories are making headway on two projects that will enable building a new lithium battery that charges faster, lasts longer, runs more safely, and might also arrive on the market in the not-too-distant future. Learn more.

Imagine pulling-up to a fuel station that supplies your car with clean, renewable fuel. Now imagine that, while you’re filling up, this same fuel-station just so happens to be providing power back to an entire industrial facility. Sound a little far-fetched?

The University of Tennessee, Knoxville is participating in its first Solar Decathlon 2011 competition, featuring its home, “Living Light.” Named for its very brightly sunlit double facade glass system, the home’s blueprint was inspired by the cantilever barns of Southern Appalachia, which feature giant eves to provide shade and a two-core design.



Today, Secretary Chu announced the selection of 40 projects across 15 states to receive more than $175 million to accelerate the development and deployment of next-generation vehicle technologies.
