The Agency for Natural Resources and Energy (ANRE) has prepared the Preliminary Report on the FY2020 Comprehensive Energy Statistics based on the results of studies, including a variety of energy-related statistics. The purpose of the report is to describe Japan's energy supply and demand situation.
1. Highlights of the preliminary report
(1) Trends in energy demand
- Overall final energy consumption decreased by 6.6% year-on-year; of this, consumption decreased by 14.9% in coal, 8.3% in city gas, 7.1% in oil, and 2.1% in electricity.
- The households sector showed an increase in energy consumption year-on-year due to the increased time spent at home because of COVID-19 and other impacts. The business sector showed a decrease due to factors including a decline in production volume in almost all manufacturing industries.
- A breakdown by sector on a year-on-year basis shows that while final energy consumption increased in the household sector by 4.8%, it decreased in the business sector by 7.7% (of this, consumption decreased by 9.5% in the manufacturing sector) and in the transportation sector by 10.3%, due to factors such as travel restrictions and a decline in production activities.
- Electricity consumption increased in the household sector by 5.0% and decreased in the business sector by 4.9% (of this, consumption decreased by 5.9% in the manufacturing sector) on a year-on-year basis.
(2) Trends in energy supply
- Overall domestic supply of primary energy decreased by 6.1% on a year-on-year basis. Supply of fossil fuels has been decreasing for seven consecutive years. Renewable energy continued to increase for the eighth consecutive year, while nuclear energy declined for the second consecutive year.
- In terms of fossil fuels, coal decreased by 8.8% on a year-on-year basis, oil by 7.9%, and natural gas and city gas by 0.2%. This was due to declining final energy consumption and other factors. As a result, the share of fossil fuels fell to 84.8%, the lowest level since the Great East Japan Earthquake. Nuclear power showed a 39.2% decrease, falling for the second consecutive year. On the other hand, renewable energy (excluding hydroelectric power) increased by 7.1%, driven by solar and wind power.
- The amount of generated electric power decreased by 2.1% on a year-on-year basis (1.0013 trillion kWh), and the ratio of non-fossil sources was 23.7%, down by 0.7 percentage points (%p) on a year-on-year basis.
- The fuel breakdown of generated electric power shows that renewable energy is 19.8%, up by 1.7%p, nuclear energy is 3.9%, down by 2.4%p, and thermal power (excluding biomass) is 76.3%, down by 0.7%p on a year-on-year basis.
- The energy self-sufficiency rate was 11.2%, down by 0.8%p on a year-on-year basis (based on IEA data).
(3) Trends in CO2 emissions
- Energy-related CO2 emissions decreased by 6.0% on a year-on-year basis at 0.97 billion tons, showing a decrease for seven consecutive years and a decrease by 21.7% from FY2013.
- 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, after this increase, the emissions are now on a decreasing trend due to a decrease in demand and advances in low-carbon electricity, backed by the spread of renewable energy, the restarting of nuclear power plants, and other factors.
- Looking at a breakdown by sector, a decrease is seen in the transportation and business sectors by 10.2% and 6.9%, respectively, while an increase is seen in the household sector by 4.9% on a year-on-year basis.
- CO2 emissions intensity of electricity (at the consumers' end) has deteriorated by 0.3% year-on-year to 0.48kg-CO2/kWh.
