Japan is depending more on renewables and nuclear power for electricity, according to a recent analysis.

Japan has expanded its reliance on renewables and nuclear power as it strives to attain net-zero emissions by 2050, according to the government’s fiscal 2021 energy supply and demand report.

However, carbon dioxide emissions from burning fossil fuels for electricity generation and other purposes increased 1.2 percent year on year to 980 million tonnes as the economy recovered from the coronavirus pandemic, marking the first increase in emissions in eight years, according to the preliminary report from the industry ministry.

Renewables accounted for 20.3 percent of Japan’s electricity generation, up 0.5 percentage point from the previous year, while nuclear power accounted for 6.9 percent, up 3.0 points. The share of thermal power generation excluding biomass decreased 3.5 points to 72.9 percent, according to the report.

Japan has set a target for nuclear power generation to provide 20 to 22 percent of electricity and renewables 36 to 38 percent in fiscal 2030. Prime Minister Fumio Kishida said in August the government will take necessary measures to restart nuclear power plants.

“Based on the results in the report, we will continue our study of measures to secure a stable energy supply and promote ‘green transformation’ toward reaching carbon neutrality,” Economy, Trade and Industry Minister Yasutoshi Nishimura told reporters.

According to the report, Japan’s electricity generation increased 3.2 percent from the previous year to over 1.03 trillion kilowatt hours, with the ratio of non-fossil fuel generation rising 3.5 points to 27.1 percent, in the year through March 2022.

Electricity consumption by companies and offices rose 5.5 percent while that of households dropped 6.2 percent as requests to stay home were discontinued amid the recovery from the pandemic.

The country’s energy self-sufficiency rate rose 2.1 percentage points from the previous year to 13.4 percent amid an expansion of renewable energy, according to the report.
