From October 2025 through September 2026, low-carbon sources supplied just over half of Greece’s electricity, at about 51%, while fossil fuels supplied almost 49%. Wind contributed around 21%, solar nearly 18%, and hydropower about 12%. Gas remained the largest individual source, supplying roughly 40% of electricity, followed among fossil fuels by coal at about 5% and oil at 3%. Clean electricity now holds a narrow majority, but Greece still depends heavily on fossil fuels, with their associated climate impacts and air pollution.

Is Electricity Growing in Greece?

Greece’s electricity picture shows encouraging clean growth, but overall consumption remains below its historical peak. The latest 2026 electricity consumption figure is about 5,500 kWh per person, roughly 760 kWh, or 12%, below the record of around 6,260 kWh in 2008. These figures do not establish whether consumption grew in the latest year, but they show that the previous peak has not been regained. By contrast, low-carbon electricity generation reached a new record of about 2,830 kWh per person, exceeding the 2024 record by roughly 260 kWh, or 10%. That clean-electricity progress is worth celebrating, while expanding overall electricity supply remains important for electrification and growing demand from AI.

Suggestions

Greece should build on its established wind and solar sectors while considering nuclear power as an additional source of low-carbon electricity. Nearby North Macedonia, where solar supplies 40% of electricity generation, offers a particularly relevant example of solar’s potential. Denmark’s 59% wind share also demonstrates how much further wind generation can grow. For nuclear power, Greece can look to regional examples such as Bulgaria and Slovenia, which generate about 37% and 40% of their electricity from nuclear, respectively, alongside France’s roughly two-thirds share. Learning from these regions could help Greece expand clean electricity generation, reduce fossil-fuel dependence, and support rising electricity demand.

History

Greece’s low-carbon electricity history features substantial hydropower fluctuations alongside important solar and wind gains. During the 2000s, hydropower fell by 1.4 TWh in 2001 and 3.1 TWh in 2007, while increases in 2003 and 2009 added about 1.9 and 1.5 TWh. The 2010s brought further alternating hydro gains and declines, including a 3.2 TWh drop in 2011, while solar achieved a notable 2 TWh increase in 2013. In the 2020s, wind added 2 TWh in 2020, hydropower increased by 2.5 TWh in 2021, and solar added 1.8 TWh in 2022 and 1.3 TWh in 2023. More recently, wind generation fell by 1.5 TWh in 2025, underscoring the importance of sustained expansion, while hydropower’s 2.7 TWh increase in 2026 provided a substantial clean-electricity boost.
