Japan turned off recently its last working nuclear reactor and just passed through one of its hottest summers. However, it managed to have no energy rationing or blackouts in 2013 and its secret is cutting back.
“Japan’s nuclear reactors have mostly been replaced by post-catastrophe efficiency gains which reduced [energy] consumption by around 15-20 percent,” said Kevin Meyerson, a retired American businessman and now an energy conservationist living in Japan. “For example, offices throughout Japan have replaced high-consumption lighting with newly developed-in-Japan low-power LED lights, cutting office electricity consumption up to 40 percent,” he added, according to the international press.
The fact that Japan has cut the energy demand by 10 percent has eliminated its need about 14 nuclear reactors, according to government figures.
But Japan is not using only green energy. It is also using fossil fuels, with unclean energy consumption going now up to 85 percent from 60 percent within just two years.
Regular light bulbs are still highly used as well, said Kenshi Itaoka, a professor at the International Institute of Carbon Neutral Energy Research, Kyushu University. “Conventional light bulbs and fluorescent lights are still used in a lot of places. This needs to change. LEDs are the way forward. We need to get the message out better,” he said.
