Primary energy self-sufficiency rate Japan FY 2013-2022

In the fiscal year 2022, the rate of primary energy self-sufficiency in Japan reached approximately 12.6 percent.Following the Fukushima nuclear disaster in 2011, all domestic nuclear reactors were switched off for security inspections and Japan was forced to switch to fossil fuels for energy production. Consequently, the self-sufficiency rate hit a decade-low of 6.3 percent in the fiscal year 2014. Japan remains dependent on fossil fuel importsFossil fuels such as natural gas and coal continue to represent the energy sources with the largest share in electricity production. Since Japan only has scarce natural resources, it is heavily dependent on fossil fuel imports for its energy production.Reasons for the increase in the energy self-sufficiency rateThe energy self-sufficiency rate indicated an increase in recent years as the Japanese government continuously works on expanding the use of renewable energy and the reactivation of nuclear power plants. The country aims to become less dependent on fossil fuel imports, decrease electricity prices, and reduce greenhouse gas emissions. The share of renewables in electricity generation increased to over 20 percent in recent years, with solar power representing the largest renewable energy source.

在财政年度2022年，日本的一次能源自给率上升至约12.6%。自2011年福岛核灾难之后，为确保安全检查，日本国内所有核反应堆均被关闭，迫使其转向化石燃料进行能源生产。因此，自给率在2014财政年度达到了十年来的最低点，为6.3%。日本继续依赖化石燃料进口。天然气和煤炭等化石燃料在电力生产中占据了最大的能源份额。由于日本自然资源稀缺，其在能源生产上对化石燃料进口的依赖程度极高。能源自给率提升的原因近年来，随着日本政府持续致力于扩大可再生能源的使用以及核电站的重新启用，能源自给率呈现出上升趋势。该国旨在减少对化石燃料进口的依赖，降低电力价格，并减少温室气体排放。近年来，可再生能源在电力生成中的占比已增至超过20%，其中太阳能是最大的可再生能源来源。
