“Japan and energy: What's the alternative?”

As Japan's earthquake and tsunami ripped through the Fukushima Daiichi nuclear power plant, the wind turbines at nearby Takine Ojiroi Wind Farm did what they were designed to do: They swayed, they stopped, they electronically checked themselves and automatically restarted. "Except for one turbine that was very close to the nuclear power plant, all the turbines were up and running after the quake.” As a source of power, wind energy is about as clean, safe and earthquake-proof as it gets -- the problem is it generates a fraction of Japan's energy needs. Compared with the massive 4,696MW output of the six reactors at Fukushima Daiichi nuclear plant, the 23 turbines at can produce just 46MW -- enough for 30,000 households. Currently, Japan gets 27% of its power from coal, 26% from gas, 24% from nuclear, 13% from oil, and 8% from hydro. The remaining 2% is occupied by renewables such as geothermal power stations, solar and wind. As exciting as alternatives may seem, the answer to Japan's future energy needs is likely to come from more traditional sources.
