Jun 28, 2013 — The Advanced Research Projects Agency-Energy, or ARPA-E, backs energy technologies that are too risky for investors, but offer a potentially huge payoff — if they work. The agency has gambled on flywheels, compressed air energy storage, lithium-air batteries, even wind-energy kites.
Apr 9, 2013 — A U.S. Senate committee held a confirmation hearing for Ernest Moniz on Tuesday, who has been nominated to be the U.S. Energy Secretary. Moniz says he will retire from MIT, where he's a professor of physics and energy systems. He would advocate for the Obama administration's "all of the above" energy strategy, which calls for continued fossil fuels development and supports nuclear energy, wind and solar.
