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

Is Electricity Growing in Greece?

Greece’s electricity consumption has not regained its historical peak, although low-carbon generation has reached a new record. The latest 2026 consumption figure is about 5,500 kWh per person, roughly 760 kWh—or 12%—below the 2008 record of around 6,260 kWh per person. These figures do not establish whether consumption increased in the latest year, but the gap from the peak is concerning as electrification and AI create additional electricity demand. Encouragingly, low-carbon electricity generation reached about 2,830 kWh per person, exceeding its previous record, set in 2024, by around 260 kWh per person, or 10%.

Suggestions

Greece should build on its substantial wind and solar generation by expanding both, while also considering nuclear power as another source of clean electricity. Nearby North Macedonia demonstrates solar’s potential, generating 40% of its electricity from solar, compared with Greece’s roughly 18%. Denmark’s wind share of nearly 60% and Ireland’s roughly one-third offer useful examples for further wind development. For nuclear, Greece can learn from nearby Bulgaria and Slovenia, where it supplies roughly 37% and 40% of electricity respectively, as well as France, where it provides about two-thirds. Combining more solar and wind with a prospective nuclear programme could increase low-carbon electricity supply and reduce dependence on fossil fuels.

History

Greece’s low-carbon electricity history shows 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, but rose by 1.9 TWh in 2003 and 1.5 TWh in 2009. The 2010s brought further alternating hydro gains and declines, including a 3.2 TWh drop in 2011, while solar delivered a notable 2 TWh increase in 2013. In the 2020s, wind added 2 TWh in 2020, and solar added 1.8 TWh in 2022 and another 1.3 TWh in 2023. Hydropower increased by 2.5 TWh in 2021, fell by 1.4 TWh in 2022, and then recorded a strong 2.7 TWh increase in 2026. Wind’s 1.5 TWh decline in 2025 underscores the importance of sustaining investment to keep clean electricity generation growing.
