hydropower nuclear power Fukushima Daiichi nuclear disaster Sendai Nuclear Power Plant imported energy
As of 2019, 37.1% of energy in Japan was produced from petroleum, 25.1% from coal, 22.4% from natural gas, 3.5% from hydropower and 2.8% from nuclear power, among other sources. Nuclear power was down from 11.2 percent in 2010. By May 2012 all of the country's nuclear power plants had been taken offline because of ongoing public opposition following the Fukushima Daiichi nuclear disaster in March 2011, though government officials continued to try to sway public opinion in favor of returning at least some to service. The Sendai Nuclear Power Plant restarted in 2015, and since then several other nuclear power plants have been restarted. Japan lacks significant domestic reserves and has a heavy dependence on imported energy. The country has therefore aimed to diversify its sources and maintain high levels of energy efficiency.
