Cogeneration in Japan’s plans post-Fukushima

Japan is considering greater use of cogeneration as part of an overall shift to renewable energy following Fukushima in 2011.

Because of the vulnerability of the country to earthquakes and other natural phenomena, the Japanese government has drawn up a plan to conserve energy use by 10 per cent compared with 2010.

The ruling Democratic party (DPJ) has pledged to do its best to end Japan’s reliance on nuclear power by the 2030s, using a combination of energy conservation, a shift to renewable energy sources and greater use of cogeneration, which captures heat emitted as a byproduct of electricity generation.

The plan also calls for a near tripling of electricity generated by renewable sources, including hydro­electric power, to 300bn kWh by 2030, and increasing the use of cogeneration from 30bn kWh to 150bn kWh over the same period.
