The Agency for Natural Resources and Energy (ANRE) has prepared the Revised Report on the FY2017 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 increased by 0.9% on a year-on-year basis, showing an increase for the first time since the occurrence of the Great East Japan Earthquake. Electricity consumption also increased by 1.5% on a year-on-year basis.
- The households sector shows a dramatic increase in energy consumption due to the impact of the severe winter. The final energy consumption by the business sector increased on a year-on-year basis for the first time in four years thanks to active economic activities.
- A breakdown by sector shows that the final energy consumption decreased in all major sectors, excluding the transportation sector, on a year-on-year basis: up by 0.8% in the business sector (of which the consumption increased by 0.8% in the manufacturing sector and by 0.9% in the other-business sector), up by 4.2% in the household sector, and down by 0.8% in the transportation sector.
- As for electricity consumption on a year-on-year basis, the household sector shows an increase for the first time in five years by 2.3% and the business sector shows an increase by 1.2% .
2) Trends in energy supply
- The overall domestic supply of primary energy increased by 1.2% on a year-on-year basis. Supply of fossil fuels has been decreasing for four consecutive years, while that of non-fossil fuels, such as renewable energy and nuclear energy, has been increasing for five consecutive years.
- The amount of generated electric power increased by 0.7% on a year-on-year basis, while the ratio of zero-emission power supply is 19.1%, up by 2.8 percentage points (%p) on a year-on-year basis.
- The energy self-sufficiency rate is 9.6%, up by 1.4%p year-on-year (based on the IEA data).
- As for the share of the primary supply in all supply, renewable energy, including hydro and unused energy, and nuclear energy show an increase by 0.8%p and 0.6%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, mainly those for power generation, show a decrease by 0.7%p and 0.4%p on a year-on-year basis, respectively. Coal shows a decrease by 0.3%p in share while remaining the same in volume.
- The amount of generated electric power was 1.0602 trillion kWh. The fuel breakdown of generated electric power shows that renewable energy is 16.0%, up by 1.4%p, nuclear energy about 3.1%, up by 1.4 %p, and thermal power about 80.9%, down by 2.8%p on a year-on-year basis, respectively.
3) Trends in carbon dioxide emissions
- Energy-oriented carbon dioxide emissions decreased by 1.6% on a year-on-year basis, showing a decrease for four consecutive years and a decrease by 10.1% from FY2013.
- The basic unit of carbon dioxide emissions for electricity improved by 4.8% year-on-year to 0.51 kg-CO2/kWh, the smallest unit after the occurrence of the Great East Japan Earthquake.
- Carbon dioxide emissions increased for four consecutive years until FY2013 due to the impact of the shutting down of nuclear power plants since the Great East Japan Earthquake hit Japan. However, after this, the emissions now tend to decrease due to the decrease in demand and the 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 by sector, a decrease is seen in the business sector by 1.8% and the transportation sector by 1.0% on a year-on-year basis, respectively, while the household sector shows an increase by 0.6%.
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 oil = 9,250 kcal = 38.7 MJ; 1MJ = 0.0258 liters)
