FY2023 Energy Supply and Demand Report (Preliminary Report)

1. Highlights of the preliminary report

(1) Trends in energy demand

Final energy consumption decreased by 3.0% year-on-year; of which, the consumption of city gas, coal, oil, and electricity decreased by 4.1%, 4.0%, 2.9% and 2.5%, respectively.

The business sector showed a decrease due to sluggish production activities in the manufacturing sector. The residential sector also showed a decrease due to the impact of the lower rate of teleworking, and the transportation sector showed a slight decrease.

• A breakdown by sector on a year-on-year basis shows that final energy consumption decreased in the business sector by 3.5% (of which, the manufacturing sector decreased by 3.7%), the residential sector decreased by 4.4%, and the transportation sector decreased by 0.6% (of which, the passenger transportation and freight transportation sectors showed a decrease of 0.6% and 0.4%, respectively).
• Electricity consumption decreased in the business sector by 2.5% on a year-on-year basis (of which, the manufacturing sector decreased by 2.9%), while the residential sector decreased by 2.7%.

(2) Trends in energy supply

Domestic primary energy supply decreased by 4.1% year-on-year. Fossil fuels decreased by 7.0%, while the share of non-fossil fuels increased by 10.6%, showing an increase in renewable energy (including hydroelectric power) for the 11th consecutive year.

• In terms of fossil fuels, a decrease was seen in all of the following sectors on a year-on-year basis, namely coal by 8.4%, natural and city gases by 7.9%, and oil by 5.5%. In terms of non-fossil fuels, nuclear power increased by 51.2%, and renewable energy (excluding hydroelectric power) increased by 5.5%, driven by photovoltaics. The share of non-fossil fuels increased to 19.2%, the highest level in 25 years.

The amount of generated electricity decreased by 1.6% on a year-on-year basis (985.4 billion kWh), showing the lowest level since FY2010. The share of non-fossil sources increased to 31.4%, showing growth beyond 30% for the first time since the Great East Japan Earthquake.

• The fuel breakdown of generated electricity shows that renewable energy was 22.9% (including hydroelectric power), up by 1.0 percentage points (%p), nuclear energy was 8.5%, up by 2.9%p, and thermal power (excluding biomass) was 68.6%, down by 4.0%p on a year-on-year basis, respectively.

The energy self-sufficiency rate was 15.2%, up by 2.6%p year-on-year (based on the IEA data), showing the highest level since the Great East Japan Earthquake.

(3) Trends in energy-related CO2 emissions

CO2 emissions decreased by 4.8% on a year-on-year basis, at 0.92 billion tons, showing a decrease by 25.9% from FY2013 and the lowest level since FY1990.

• In FY2023, the total amount of energy supply and demand shows a decrease for two consecutive years because of a decrease in energy consumption and an increase in non-fossil fuels.
• Looking at the breakdown by sector, a decrease was seen in the business sector by 5.6%, the residential sector by 7.8%, and the transportation sector by 0.8%, on a year-on-year basis.

The CO2 intensity for electricity (on the consumer end) was 0.45kg-CO2/kWh, down by 4.1% on a year-on-year basis.

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