It is said that the amount of solar energy that bathes the Earth in one year is equal to approximately 90 trillion tons of coal. That’s approximately 30,000 times the world’s energy consumption. When silicon semiconductors are hit by light, they produce electricity. Solar power generation uses this phenomenon to convert light energy from the sun directly into electric power. The amount of solar energy used in Japan has grown steadily over recent years and the cumulative total had reached approximately 42 million kW as of the end of FY2016.
TEPCO currently owns three mega solar power stations including the Ukishima Solar Power Station (output: 7,000 kW) that commenced operation in August 2011.
