Total Primary Energy Demand (TPED) decreased by 4.9% year-on-year in May, as the demand for all energy sources decreased.

Total Final Consumption (TFC) decreased by 6.1% year-on-year in May, as energy use declined in the industrial and transport sectors due to the economic recession and higher energy prices.

5. Coal

Coal use dropped by 9.5% year-on-year in May, as it started to decline in the industrial sector and fell more sharply in the power generation sector.

6. Petroleum

The final use of petroleum went down by 8.4% year-on-year in May, as it decreased in both of the industrial and transport sectors.

7. Gas

Gas use declined by 0.3% year-on-year in May, as it steadily declined in the power generation and building sectors, although it rebounded in the industrial sector.

8. Electricity

Electricity use dropped by 1.8% year-on-year in May, led by the industrial sector, although it grew in the building sector.

9. Nuclear

The total nuclear generation was down 1.0% year-on-year in May despite the growth in nuclear installed capacity, because the average capacity factor decreased.

10. Heat and Renewable energy

Heat energy use went up by 1.2% year-on-year in May, led mostly by the commercial sector, although it declined in the residential sector.

Renewable & other energy use decreased by 5.7% year-on-year in May, as it declined in both of the power generation and end-use sectors.

11. Industry

Industrial energy use decreased by 7.0% year-on-year in May, as most of the sectors consumed less energy, except a few sectors.

12. Transport

Transport energy use fell by 8.9% year-on-year due to the base effect from the same month last year when energy use surged in the road transport sector.

13. Buildings

Energy use in buildings slightly increased in May, as it grew in the residential and public sectors, while it declined in the commercial sector.

14. Power Generation

The total power generation and fuel input decreased by 1.4% and 5.2% respectively in May on a year-on-year basis, as electricity use declined.
