Japan Looks to LED Light Bulbs to Reduce Energy Usage after Shutting Down Nuclear Plants


1200x-1

Just a few years after the Fukushima tsunami and nuclear incident, Japan is looking to address its power demands after shutting down its nuclear program with the use of energy-efficient LED lights

Japan’s push to keep power flowing after it shuttered its nuclear program may best be illustrated by 73 million light bulbs. That’s the number of LED bulbs sold in Japan since the start of 2012, representing about 30 percent of all bulbs sold there. The LEDs, which consume a fifth of the energy used by standard lights, are key to the country’s strategy to make energy use more efficient, even as it pursues alternative sources such as solar power. 

Four years after the Fukushima nuclear meltdown spurred the closure of Japan’s many reactors, knocking out 30 percent of Japan’s power supply, the drive to reduce energy consumption has sparked a national campaign that includes everything from improved insulation for homes to train stations powered by the braking of subway cars and vending machines that recycle waste heat and generate power with solar panels on top.
