Japan's green dreams delayed

In the wake of the Fukushima Dai-ichi nuclear disaster, with nuclear power’s future uncertain, Japan's parliament passed a bill in August aiming to boost green energy production. The bill-commonly called the feed-in tariff or FIT law-requires Japan's 10 power utilities to purchase electricity generated by suppliers of such renewable energy sources as solar, wind, and biomass and is slated to go into effect this summer. But its implementation is far from ready, and some energy experts believe it will be decades before it really helps.
