Global Electricity Supply (2024)

In 2024, global electricity generation is projected to reach 31,029 TWh. Coal remains the dominant source, contributing 34.5% of the total, followed by renewables at 31.7%. Gas accounts for 21.8%, while nuclear provides 9.1%. Other non-renewables make up the remaining 2.8%. While coal still plays a significant role, the growth of renewable energy is reshaping the global electricity mix.

• Asia-Pacific is the largest electricity producer, generating 16,229 TWh, with coal (54.8%) being the dominant source, followed by renewables (29.5%) and gas (9.5%).

• The Americas generate 6,986 TWh, with a relatively balanced mix: gas (35.5%), renewables (37.0%), and nuclear (13.4%) leading the supply.

• Europe produces 3,875 TWh, with renewables (48.7%) surpassing all other sources, followed by nuclear (20.9%) and gas (16.2%).

• Eurasia contributes 1,516 TWh, where gas (46.8%) is the primary source, followed by coal (18.2%) and renewables (19.7%).

• The Middle East generates 1,492 TWh, with a strong reliance on gas (67.8%), while renewables (5.2%) and nuclear (3.1%) play smaller roles.

• Africa produces 931 TWh, with gas (44.1%) and coal (25.0%) forming the backbone of supply, while renewables (23.7%) are growing steadily.

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.
