GE Mag Says Natural Gas-Powered Turbines Could Be the Answer

The world needs more green energy. It has to be reliable, too. How can we bridge the gap? The folks at General Electric's Txchnologist say innovations in natural-gas powered turbines could be the answer to meeting renewable portfolio standards in the U.S. Some of the arguments: The newest natural gas turbines can fire up rapidly and provide power to the grid when renewable energy falls short, that fire-up is more rapid than what can be achieved by a coal plant, and natural gas is a cleaner burning fuel anyway. Another argument: They look really cool. Just kidding.
