FY2023 Energy Supply and Demand Report (Revised Report)

1．Highlights of the revised report

(1) Trends in energy demand

• Final energy consumption decreased by 2.7% year-on-year; by energy source, petroleum decreased by 3.0%, city gas by 2.5%, electricity by 2.5%, and coal by 2.2%.
• The business sector showed a decrease due to sluggish production in the manufacturing industry. The household sector also recorded a decline, due to a warm winter (except in March), a decline in the telework implementation rate, and other factors. The transportation sector showed a slight decrease.
  • A breakdown of the final energy consumption of each sector on a year-on-year basis shows decreases of 3.2% in the business sector (with the manufacturing sector down by 3.2%), marking the second consecutive year of decline; 4.4% in the household sector, continuing its downward trend for a third consecutive year; and 0.4% in the transportation sector (with passenger transportation down by 0.3% and cargo transportation down by 0.6%), representing its first decrease in three years. As a result, all sectors experienced declines.
  • Electricity consumption in the business sector decreased by 2.4% year-on-year (with the manufacturing sector down by 2.8%), while that of the household sector fell by 2.7%.

(2) Trends in energy supply

• Domestic primary energy supply decreased by 4.0% year-on-year. The supply of fossil fuels dropped by 7.0%, marking the largest decline since fiscal 1991. The supply of non-fossil fuels increased by 11.1%, with renewable energy (including hydroelectric power) having grown for eleven consecutive years.
  • Regarding fossil fuels, coal decreased by 8.7%, natural gas and city gas by 7.9%, and petroleum by 5.2%. The share of non-fossil fuels rose to 19.3%, the highest level in 25 years, driven by a 51.7% increase in nuclear power and a 6.3% increase in renewable energy (excluding hydroelectric power), with solar and biomass energy making major contributions.
• Electricity generation decreased by 1.4% year-on-year to 0.9877 petawatt-hours, marking the lowest level since fiscal 2010. The share of non-fossil power sources reached 31.4%, exceeding 30% for the first time since the Great East Japan Earthquake.
  • The power generation mix showed that renewable energy (including hydroelectric power) accounted for 22.9% (up by 1.0 percentage point), nuclear energy for 8.5% (up by 2.9 percentage points), and thermal power (excluding biomass-fired generation) for 68.6% (down by 4.0 percentage points), all compared to the previous year.
• The energy self-sufficiency rate (on an IEA basis) rose by 2.6 percentage points from the previous year to 15.3%, marking the highest level since the Great East Japan Earthquake.

(3) Trends in energy-related CO2 emissions

• CO2 emissions decreased by 4.1% year-on-year to 0.92 gigatons. This is the lowest emissions level since fiscal 1990, representing a 25.4% decrease from fiscal 2013.
  • The emissions continued to decline for the second consecutive year, driven by a significant reduction in fossil fuel use, as total energy consumption fell and the use of non-fossil fuels expanded.
  • By sector, emissions decreased by 4.7% in the business sector, 6.8% in the household sector, and 0.7% in the transportation sector, compared to the previous year.
• CO2 emissions intensity for electricity (at the point of use) decreased by 2.9% year-on-year to 0.46 kg-CO2/kWh.

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