California is known for its "green" reputation, so it might be a surprise that residents in Southern California still depend on coal power when they turn on the lights.
On the windswept tarmac of the former Alameda Naval Air Station, an inventive group of scientists and engineers are test-flying a kite-like tethered wing that may someday help revolutionize clean-energy. QUEST explores the potential of wind energy and new airborne wind turbines designed to harness the stronger and more consistent winds found at higher altitudes.
Energy storage (through batteries) is something we use everyday in our cell phones and computers. So it may be a little surprising that when it comes to the electric grid, storing energy is something that's rarely done.
Since people seem to nod off a bit when I say I'm working on a story about energy efficiency, I've had to re-tool my pitch. "It's a story about how installing solar panels or a wind turbine is the last thing you should do to green your house," I say, perhaps a little over-dramatically.
