As of 2025, Greece's electricity consumption is virtually split evenly between fossil fuels and low-carbon sources. Slightly more than half of the electricity, around 50%, comes from fossil sources like gas and coal. Gas accounts for nearly 45% of electricity generation, while coal contributes a modest 5%. Low-carbon sources make up almost the other half of the electricity mix, with solar energy leading the way at approximately 23%, closely followed by wind at about 21%. Hydropower adds a smaller share, close to 7%, shaping a diverse profile of low-carbon energy generation in Greece. The transition towards cleaner energy is evident, but there remains potential for further growth in low-carbon electricity generation.

Is Electricity Growing in Greece?
Electricity consumption in Greece has seen a decline compared to its peak. In 2025, the total consumption is recorded at 5089 kWh/person, which is a significant decrease of 1172 kWh/person from the highest level of 6261 kWh/person in 2008. This reduction suggests that electricity usage overall has not been growing. Additionally, low-carbon electricity generation per person has similarly seen a minor decline. In the latest year, low-carbon electricity is at 2536 kWh/person, slightly below the record peak of 2582 kWh/person recorded in 2024, representing a small reduction of 46 kWh/person. These trends raise concerns, highlighting that despite a robust base in low-carbon technologies, further expansion is needed to meet future demands.
Suggestions
To bolster its low-carbon electricity generation, Greece should focus on expanding its existing wind and solar capabilities, given their significant current contributions. Globally, successful case studies offer valuable insights, such as Iowa and Denmark, where wind energy powers 60% and 59% of electricity, respectively, presenting models for enhancing wind energy share. Nuclear energy should not be overlooked either. France and Slovakia demonstrate the potential with nuclear, generating a substantial 70% and 66% of electricity from this source, respectively. Greece could consider nuclear as a viable avenue to ensure a more stable and clean energy supply. Emulating these examples would further enhance Greece's commitment to sustainable and clean energy solutions, aligning with global sustainability goals and reducing the environmental impact of electricity generation.
History
The history of low-carbon electricity generation in Greece reveals both growth and fluctuation. In the early years of the century, hydropower faced significant ups and downs, with noticeable declines in 2001 and 2007 but subsequent rebounds in the latter part of the decade. The 2010s witnessed substantial strides in solar energy, marked by a remarkable increase in 2013, and continued steady growth through 2023, demonstrating a positive trend in solar adoption. Wind energy also saw an uptick in 2020, contributing to Greece's low-carbon energy mix. However, recent years have shown some declines in specific years, such as 2025 for wind, indicating potential areas for improvement. Despite previous challenges, the focus should remain on expanding Greece's low-carbon electricity generation capacity to ensure continued progress and address the demands of a modern, sustainable energy landscape.
