The Agency for Natural Resources and Energy (ANRE) has prepared the Revised Report on the FY2018 Comprehensive Energy Statistics based on the results of studies including a variety of energy-related statistics to describe Japan’s energy supply and demand situation.
1. Highlights of the revised report
1) Trends in energy demand
Overall final energy consumption decreased by 2.7% year-on-year, of which the consumption decreased by 4.1% in oil, 3.3% in city gas, 2.0% in electricity and 1.9% in coal.
The households sector shows a dramatic decrease due to the impact of the warmer winter compared with the consumption in FY2017 when the winter was severe. Final energy consumption by the business sector shows moderate growth in economic activities, while showing a decrease in such consumption due to a decrease in production of iron and steel and ethylene, the further progress of energy efficiency and conservation and other elements.
- A breakdown by sector on a year-on-year basis shows that final energy consumption decreased in the business sector by 2.1% (of which consumption decreased by 1.5% in the manufacturing sector), decreased in the transportation sector by 1.2% and decreased in the household sector by 7.8%, representing a decrease in all major sectors.
- As for electricity consumption on a year-on-year basis, the household sector shows a decrease by 4.6% and the business sector also shows a decrease by 1.0%.
2) Trends in energy supply
Overall domestic supply of primary energy decreased by 1.8% on a year-on-year basis. Supply of fossil fuels has been decreasing for five consecutive years, while supply of non-fossil fuels, such as renewable energy and nuclear energy, has been increasing for six consecutive years.
- As for the share of the primary supply in the total supply, renewable energy, including unused energy, and nuclear energy, show an increase by 0.5 percentage points (%p) and 1.4%p year-on-year, respectively, due to the further dissemination of renewable energy for power generation and the advancement in restarting nuclear power plants. Meanwhile, oil and natural gas show a decrease of 1.4%p and 0.5%p on a year-on-year basis, respectively, mainly for power generation. Coal shows a decrease in volume, while maintaining its equal share of the total.
The amount of generated electric power decreased by 0.8% on a year-on-year basis (1.0512 trillion kWh), while the ratio of non-fossil sources is 23.0%, up by 3.9%p on a year-on-year basis.
- The fuel breakdown of generated electric power shows that renewable energy is 16.9%, up by 0.9%p, nuclear energy is 6.2%, up by 3.1%p, and thermal power is 77.0%, down by 3.9%p on a year-on-year basis, respectively.
The energy self-sufficiency rate is 11.8%, up by 2.3%p on a year-on-year basis (based on IEA data).
3) Trends in carbon dioxide emissions
Energy-oriented carbon dioxide emissions decreased by 4.6% on a year-on-year basis at 1.06 billion tons, showing a decrease for five consecutive years and a decrease by 14.2% from FY2013.
The basic unit of carbon dioxide emissions for electricity (at consumers’ end) has improved by 4.7% year-on-year to 0.49kg-CO2/kWh.
- Carbon dioxide 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 the decrease in demand and advancement in low-carbon electricity, etc., backed by the dissemination of renewable energy, the restart of nuclear power plants, and other factors.
- Looking at a breakdown of decreases by sector, the figures are 4.1% for the business sector, 11.1% for the household sector, and 1.4% for the transportation sector on a year-on-year basis, respectively.
