Greece: electricity in context
Electricity generation in Greece reached 58.3 TWh in 2025. That is similar to Singapore. Natural gas is the largest source at 38.4%, ahead of solar power (22.2%) and wind power (20.4%).
The renewable share stood at 49.7%, placing Greece 60th of 158 ranked countries. This puts it 16 points above the world average of 33.8%. It is also above the average for Europe (41.6%). That beats the EU-27 average of 47.7%. Each kilowatt-hour emitted on average 315 g CO₂e, against a world average of 458 g. That makes the grid somewhat cleaner than the world average. On carbon intensity, Greece ranks 64th of 158 from the cleanest.
Over the past decade natural gas added more generation than any other source (+13.3 TWh since 2015, plus 20.6 percentage points of share). Coal moved the other way, falling by 19.4 TWh. Taken together, the renewable share rose by 20.6 percentage points over the decade. Total generation grew by 7.2 TWh over the same period. Carbon intensity dropped from 604 to 315 g/kWh, a 48% cut.
Coal is in clear retreat: its share fell from 43.3% in 2015 to 4.7% in 2025, after peaking at 73.9% back in 1994. In absolute terms, coal generation peaked in 2005 at 35.5 TWh and has since fallen 92%.
Wind and solar together provided 42.6% of electricity (solar 22.2%, wind 20.4%), compared with 17.3% worldwide. Per person, that is 1,300 kWh of solar electricity a year, 3.9× the global average. In solar electricity per person, Greece ranks 6th in the world. Wind adds 1,198 kWh per person, the 17th-highest figure of 156 countries. Solar first passed 1% of the mix in 2011.
Greece generates 5,863 kWh of electricity per resident each year, 1.5 times the global average. Greece is a net exporter, selling 2.7 TWh more electricity abroad than it imports (5% of domestic demand).

Renewables and carbon intensity
Greece against the world, Europe and EU-27 averages.
Total energy: beyond electricity
Primary energy covers transport, heating and industry too. Renewables supply 21.1% of primary energy and fossil fuels 78.9% (2024). Per person, that is 31,966 kWh a year (world: 21,654).
Substitution method: non-fossil electricity is converted to the primary energy a fossil plant would have needed.

Power plants in Greece
The WRI Global Power Plant Database lists 90 utility-scale plants in Greece with a combined capacity of 14.7 GW. Gas plants account for the largest slice (36% of listed capacity). The biggest single plant is Agios Dimitrios power station (1,595 MW, Coal). The database was last updated in 2021, so newer wind and solar farms and rooftop PV are under-represented.
