Speaking of backstops: "In Hawaii, Italy, and other places with abundant sunshine and high electricity rates, it’s already cheaper for consumers to install rooftop solar panels than to buy power from their local utility. By 2015 panels will have reached that point of so-called grid parity in much of the U.S., Europe, and Japan, Bloomberg New Energy Finance predicts. Over the past two years, BNEF says, solar thermal plants have trimmed the price of their power by 3 percent, to about 27¢ per kilowatt hour, while electricity from photovoltaic installations has plunged 41 percent, to 17¢." --from Business Week
