The Agency for Natural Resources and Energy (ANRE) has prepared preliminary figures on the FY2017 Comprehensive Energy Statistics based on the results of studies including a variety of energy-related statistics, and generated a preliminary report of the FY2017 Energy Supply and Demand Report.
1. Highlights of the preliminary report
1) Trends in energy demand
- Overall final energy consumption increases by 0.4% on a year-on-year basis, showing an increase for the first time since the occurrence of the Great East Japan Earthquake, while electricity consumption has remained the same for two consecutive years.
- The households sector shows a dramatic increase in energy consumption due to the impact of a severe winter. The business sector remains the same due to the advancement of energy-conservation efforts while showing active economic activities.
- A breakdown by sector on a year-on-year basis shows that the final energy consumption remains the same in the business sector (of which the consumption increased by 0.6% in the manufacturing sector), decreased in the transportation sector by 0.8% and increased in the household sector by 4.1%, which shows an increase only in the household sector.
- As for electricity consumption on a year-on-year basis, the household sector has shown an increase for the first time in five years by 2.1% and the business sector has shown a decrease by 0.8%.
2) Trends in energy supply
- The overall domestic supply of primary energy shows an increase by 1.0% on a year-on-year basis. The 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 shows an increase by 0.6% on a year-on-year basis, while the ratio of zero-emission power supply is 19.3%, up by 2.9 percentage points on a year-on-year basis.
- The energy self-sufficiency rate is 9.5%*, up by 1.2 percentage points on a year-on-year basis (based on the IEA data).
*Note: The exact figure is 9.46%, which could also be rounded down to 9%.
- As for the share of the primary supply in all supply, renewable energy, including unused energy, and nuclear energy show an increase by 0.7 percentage points and 0.6 percentage points on a year-on-year basis, 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 by 0.6 percentage points and 0.4 percentage points on a year-on-year basis, respectively, mainly for power generation. Coal shows a decrease by 0.3 percentage points in share while remaining the same in volume.
- The amount of generated electric power was 1.0560 trillion kWh. The fuel breakdown of generated electric power shows that renewable energy is 16.1%, up by 1.5 percentage points, nuclear energy about 3.1%, up by 1.4 percentage points, and thermal power about 80.7%, down by 2.9 percentage points on a year-on-year basis, respectively.
3) Trends in carbon dioxide emissions
- Energy-oriented carbon dioxide emissions show a decrease by 1.4% on a year-on-year basis, which is a decrease for four consecutive years and a decrease by 10.0% from FY2013.
- The basic unit of carbon dioxide emissions for electricity has improved by 2.7% year-on-year to 0.52kg-CO2/kWh.
- 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, the emissions now tend to decrease due to the decrease in demand and the advancement in low-carbon electricity, etc. 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 1.9% and the transportation sector by 0.9% on a year-on-year basis, respectively, while the household sector shows an increase by 1.8%.
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 = 9,250kcal = 38.7 MJ; 1MJ = 0.0258 liter)
