Petroleum consumption was down 0.8% year-on-year in April despite the rapid consumption growth in the transport sector, as it declined in the industrial sector.

7. Gas

Natural gas consumption decreased by 2.1% year-on-year in April despite the consumption growth in the city gas production sector, as it declined in the power generation sector.

City gas consumption increased in the industrial and buildings sectors, and accordingly, the total consumption rose by 10.6% year-on-year.

8. Electricity

Electricity consumption went up by 1.0% year-on-year in April despite decreased consumption in the industrial sector, as it increased in the buildings sector.

9. Nuclear energy

The total nuclear generation surged by 50.1% year-on-year in April partly due to base effect and the increased average capacity factors

10. Heat and Renewable energy

Heat energy use rose by 3.7% year-on-year in April because of lower temperature and the start-up of a new facility.

Renewable & other energy use went up by 7.2% on a year-on-year basis (in April), and by energy source, fuel cells, solar PV and bioenergy made the largest contributions.

11. The Industry Sector

Industrial energy consumption fell by 3.3% year-on-year in April due to the sluggish production in the petrochemical and primary metals sectors.

12. The Transport Sector

Energy consumption rose by 7.1% year-on-year in April in the transport sector as a result of a surge in the road transport sector, although the consumption plunged in the domestic navigation sector.

13. The Buildings Sector

Energy consumption in buildings went up by 6.2% year-on-year in April, even at higher prices, due to the increased number of heating degree days.

14. Transformation

The total energy input to power stations increased by 1.1% year-on-year in April, as nuclear generation surged, while coal and gas-fired generation continued the downward slide.
