Asia-Pacific Electricity Supply (2022-2027)

Trends (2022-2024):

• Coal remains the dominant source of electricity generation, growing steadily from 8,230 TWh in 2022 to 8,894 TWh in 2024. While growth is slowing, it continues to be a major contributor to the region's power mix.

• Renewables are seeing the fastest increase, expanding from 3,938 TWh in 2022 to 4,786 TWh in 2024, indicating strong momentum in clean energy adoption.

• Nuclear energy is also growing, rising from 747 TWh in 2022 to 820 TWh in 2024, reflecting investment in new reactors and higher utilization of existing plants.

• Gas remains relatively stable, with moderate growth from 1,481 TWh in 2022 to 1,541 TWh in 2024, suggesting continued reliance on natural gas as a transitional fuel.

• Other non-renewables, including oil and miscellaneous sources, are declining from 215 TWh in 2022 to 188 TWh in 2024, reflecting a shift away from less efficient and more expensive fossil fuels.

Future Projections (2025-2027):

• Renewables are expected to see the most significant growth, reaching 6,986 TWh by 2027, further increasing their share of the energy mix.

• Nuclear continues its upward trajectory, rising to 986 TWh by 2027, showing a sustained commitment to low-carbon baseload power.

• Coal generation is projected to plateau, growing only slightly to 9,041 TWh by 2027, as policy shifts and economic factors limit expansion.

• Gas continues gradual growth, reaching 1,615 TWh by 2027, suggesting that it will remain a key player in balancing energy supply.

• Other non-renewables are expected to decline further, dropping to 153 TWh by 2027, reinforcing the phase-out of less efficient energy sources.

Electricity Supply and TWh

Electricity supply is the total energy generated for use in homes, businesses, and industries. It is measured in terawatt-hours (TWh), with 1 TWh equaling one trillion watt-hours. Different sources—coal, gas, nuclear, and renewables—contribute to the mix, varying by region and policy.
