In 2025, Greece's electricity consumption reveals a blend of fossil and low-carbon sources. More than half of the electricity supply, specifically 54%, comes from fossil fuels, with natural gas being the main contributor at about 44%. Coal and oil contribute smaller portions, around 5% and 4%, respectively. On the cleaner side of the spectrum, low-carbon energy sources account for nearly 46% of the electricity mix. Wind energy, generating approximately 20%, and solar power, providing 17%, are the key contributors within this category. Hydropower also plays a notable role, contributing around 8%, while biofuels add a small fraction, just over 1%.

Is Electricity Growing in Greece?
Despite these efforts towards a cleaner electricity mix, Greece faces a concerning trend in its overall electricity consumption and low-carbon electricity generation. The per capita electricity consumption in Greece was 5127 kWh in 2025, significantly lower than the record of 6261 kWh per person achieved in 2008. This decline of more than 1100 kWh suggests stagnation in electricity growth, which is disappointing in the context of enhancing electrification and fostering technological advancements. Furthermore, the decrease in low-carbon electricity generation, from a record 2564 kWh per person in 2024 to 2357 kWh in 2025, is disheartening, indicating a backstep in Greece's green energy ambitions.
Suggestions
For Greece to advance in its low-carbon electricity generation, expansion of wind and solar capacities is crucial. Drawing from international success stories, Greece can look to countries like Denmark and states like Iowa and South Dakota, where wind energy comprises close to 60% of electricity generation, as an exemplary model for wind energy expansion. Moreover, the significant solar achievements in countries like North Macedonia and states like California and Nevada—which boast solar electricity generation fractions of 49% and 31%, respectively—highlight pathways for solar expansion. Additionally, embracing nuclear energy can significantly bolster Greece's clean energy landscape. By observing the substantial nuclear power contributions in nations such as France and Slovakia, which obtain around two-thirds of their electricity from nuclear, Greece could lay down foundations for a sustainable and resilient electricity system.
History
Historically, Greece's movement towards low-carbon electricity has seen fluctuations, predominantly within hydroelectric and solar energy. In the early 1980s and early 2000s, hydroelectric generation saw periodic declines. Conversely, the 2010s marked an energizing era for solar power, especially with notable growth in 2013. Wind power began to make a mark, particularly from 2020. However, hydropower witnessed inconsistent performance over the decades, which underscores the need for more stable and reliable low-carbon energy sources going forward. Greece's past success with solar and the recent accelerated growth in wind present promising avenues for a clean energy future, complementing the potential development of nuclear infrastructure to meet growing electricity demand and combat the adverse impact of fossil fuels.
