FY2021 Energy Supply and Demand Report (Revised Report)

1. Highlights of the revised report

（1）Trends in energy demand

• Overall final energy consumption increased by 1.6% year-on-year; of this, consumption of coal increased by 10.0%, city gas by 4.3%, and electricity by 1.1%, while consumption of oil decreased by 0.9%.
• The business sector and the transportation sector showed an increase backed by the recovery from sluggish business activities in the previous fiscal year caused by COVID-19. The household sector showed a decrease due to a decline in time spent at home because of the relaxation of the behavioral restrictions.
  • A breakdown by sector on a year-on-year basis shows that final energy consumption increased by 4.0% in the business sector （of this, the consumption increased by 4.8% in the manufacturing sector）, and 0.7% in the transportation sector, while it turned to a decrease by 6.5% in the household sector, which was the only sector that showed an increase in the previous fiscal year.
  • Electricity consumption on a year-on-year basis increased by 4.2% in the business sector （of this, the consumption increased by 2.5% in the manufacturing sector）, while it decreased by 6.1% in the household sector.

（2）Trends in energy supply

• Overall domestic supply of primary energy increased by 4.1% year-on-year. Supply of fossil fuels increased by 2.0%, an increase for the first time in eight years. Supply of renewable energy （including hydroelectric power） increased for nine consecutive years.
  • In terms of fossil fuels, coal increased by 8.8% and oil increased by 2.9%, but natural gas and city gas decreased by 6.4% on a year-on-year basis. Non-fossil fuels, on a year-on-year basis, increased by 15.7%; of this, nuclear energy increased by 85.6%, and renewable energy （excluding hydroelectric power） increased by 11.7%, driven by solar power and biomass generation. The share of non-fossil fuels increased to 16.8%, exceeding the increase in fossil fuels and marking the highest level since the Great East Japan Earthquake.
• The amount of generated electric power increased by 3.2% on a year-on-year basis （1.0328 trillion kWh）. The ratio of non-fossil sources was 27.1%, up by 3.4 percentage points （pp） on a year-on-year basis.
  • The fuel breakdown of generated electric power shows that renewable energy was 20.3% （including hydroelectric power）, up by 0.4 pp, nuclear energy was 6.9%, up by 3.0 pp, and thermal power （excluding biomass） was 72.9%, down by 3.4 pp on a year-on-year basis.
• The energy self-sufficiency rate was 13.3%, up by 2.0 pp year-on-year （based on the IEA data）, marking the highest level since the Great East Japan Earthquake.

（3）Trends in energy-related CO2 emissions

• Total CO2 emissions increased by 2.1% year-on-year, while the amount thereof was 990 million tons, down by 20.0% compared to the FY2013 level and remaining below one billion tons following on FY2020.
  • CO2 emissions increased for four consecutive years until FY2013 due to the impact of the shutting down of nuclear power plants after the Great East Japan Earthquake. However, the emissions were on a declinig trend thereafter due to a decrease in energy demand, expansion of renewable energy and the restart of nuclear power plants. In FY2021, emissions increased on a year-on-year basis for the first time in eight years, due to the recovery from the sluggish economy caused by COVID-19.
  • Looking at a breakdown by sector on a year-on-year basis, increases of 4.7% in the business sector and 0.8% in the transportation sector were seen, while a decrease of 6.3% was recorded in the household sector.
• The basic unit of CO2 emissions for electricity （at consumers’ end） was 0.47kg-CO2/kWh, remaining almost the same as that in the previous fiscal year.

Note: Energy volumes in this material are shown in energy units measured in joules. Oil equivalent data in 1 million kl will be obtained from the PJ data （PJ ［petajoule］: 10 to the 15th power joules） herein, multiplied by 0.0258. （Oil equivalence: 1 liter of crude oil = 9,250 kcal = 38.7 MJ. 1 MJ = 0.0258 liters.）
