From November 2025 through October 2026, just over half of Greece’s electricity consumption came from low-carbon sources, while fossil fuels supplied almost half. Wind provided about 21%, solar 17%, and hydropower 12%, making these the main sources of clean electricity. On the fossil side, gas dominated at around 40% of electricity consumption, with coal contributing about 5% and oil 3%. Greece has therefore reached a slim clean-electricity majority, but substantial fossil fuel use still contributes to climate change and air pollution.

Is Electricity Growing in Greece?

Greece’s latest figures show record progress in clean electricity, although overall electricity consumption remains below its historical peak. In 2026, consumption stood at around 5,500 kWh per person, roughly 745 kWh, or 12%, below the 2008 record of about 6,300 kWh per person. Low-carbon electricity generation, however, reached about 2,830 kWh per person, exceeding the previous record set in 2024 by around 266 kWh, or 10%. That clean-electricity growth is encouraging, but the gap below peak total consumption underlines the importance of preparing electricity supply for future demand from electrification and AI.

Suggestions

Greece should build on its substantial wind and solar generation by expanding both technologies, alongside grid connections and storage to support growing electricity use. Nearby North Macedonia, where solar supplies 40% of electricity generation, offers a particularly relevant example of solar’s potential. Denmark’s 58% wind share also demonstrates how much further wind can contribute. Greece should additionally consider developing nuclear electricity, drawing lessons from neighboring Bulgaria, where nuclear provides 36% of generation, and Slovenia, where it supplies 43%. France’s roughly two-thirds nuclear share provides another example of nuclear’s ability to anchor a low-carbon electricity system. Combining expanded solar and wind with nuclear would broaden Greece’s clean-electricity options.

History

Greece’s low-carbon electricity history shows a variable hydropower contribution alongside more recent advances in solar and wind. During the 2000s, hydropower’s year-to-year changes ranged across several TWh, including gains of about 1.9 TWh in 2003 and 1.5 TWh in 2009. Further hydro gains included 1.8 TWh in both 2010 and 2013, followed by roughly 1.5–1.7 TWh in 2015 and 2018. Solar made a major advance of 2 TWh in 2013, while wind added another 2 TWh in 2020. In the 2020s, hydropower increased by 2.5 TWh in 2021 and solar by 1.8 TWh in 2022. The latest year, 2026, brought encouraging gains of 2.6 TWh from hydropower and 1.4 TWh from wind, reinforcing the case for sustained clean-electricity expansion.
