Global GridGreece's energy mix and electricity
🇬🇷 In 2025, Greece generated 57.9 TWh of electricity. The largest source was gas at 40%, followed by wind (21%) and solar (20%). In total, 48% came from low-carbon sources (nuclear and renewables) and 52% from fossil fuels.
On average, each kilowatt hour produced about 324 grams of carbon dioxide (CO₂), below the world average of 458 grams in 2025. That makes Greece the 68th cleanest of 158 countries that generate at least 1 TWh a year.
Electricity demand was 55.4 TWh. Greece exported 2.53 TWh more electricity than it imported.
Since 2000, electricity generation has grown by 9.5%, from 52.9 TWh. The low-carbon share went from 8% to 48%. The biggest rise was in gas, from 11% to 40% of generation. The biggest fall was in coal, from 65% to 5%. Carbon intensity fell from 823 to 324 grams per kWh.

Total energy mix in 2024
Electricity is only part of the energy Greece uses: fuel for transport, heating and industry counts too. In 2024, Greece used 321 TWh of energy in all (primary energy). The largest source was oil at 55%, followed by gas (21%) and wind (9.2%). Fossil fuels made up 79% and low-carbon sources (nuclear and renewables) 21%.
- Oil 55%
- Gas 21%
- Wind 9.2%
- Solar 7.8%
- Coal 3.3%
- Hydro 2.5%
- Biofuels 0.9%
- Other renewables 0.7%

Primary energy, with nuclear and renewable electricity counted as the fuel a power station would need to make it (the "substitution method"). Here "other renewables" is the Energy Institute's "geothermal, biomass and other" power generation, and biofuels are liquid fuels such as ethanol and biodiesel.

Energy security score
Moderate. Greece ranks 95th of 158 countries and 27th of 39 in Europe. The score shows how well a country could keep electricity affordable and on if fuel supplies were disrupted.
| Measure | Score |
|---|---|
| Produces its own energy In 2024, Greece produced energy equal to 24% of all the energy it used (100% or more scores full marks). | 24 |
| Variety of power sources How evenly generation is spread across nine sources. The largest, gas, made 40%. | 84 |
| Little reliance on imported power Greece exported more electricity than it imported, so it scores full marks. | 100 |
| Low-carbon power Nuclear and renewables made 48% of generation. | 48 |
| Low gas and oil use Gas and oil made 48% of generation; the score is 100 minus that share. | 53 |
The five measures are weighted 30%, 20%, 20%, 15% and 15%. How the score works.
Oil and gas pipelines
Global Energy Monitor lists 2,827 km of oil and gas pipelines operating in Greece, 148 km being built and 3,064 km proposed (lengths measured along the mapped routes; a pipeline crossing borders counts in full for each country). For liquefied natural gas (LNG), shipped by sea, it lists 2 import terminals operating (4 more being built or proposed).
