Asahi notes that the government in November 2009 started requiring utilities to buy surplus electricity from household solar panels at 48 yen per kilowatt-hour (about 40 U.S. cents), or double the previous price. And here is the best part:
Of the domestic shipments, panels for residential use accounted for 430,000 kilowatts, up 2.3 times from the previous year. That generation capacity is equivalent to a small nuclear reactor.
It wouldn't cost that much, all things considered, to change the way we consume electricity, and make a huge difference in terms of reducing the dependency on nuclear energy.
