As of 2025, Greece is in a transitional phase in its electricity generation, balancing almost evenly between fossil and low-carbon sources. A little more than half, precisely 50.2%, of Greece's electricity is still derived from fossil fuels, with natural gas being the predominant source. The share of natural gas in electricity generation stands at around 45%, while coal contributes a smaller percentage. On the low-carbon side, nearly half of Greece's electricity is generated from clean sources. Solar energy generates approximately 22.5%, wind power contributes about 21%, and hydropower provides close to 7% of the country’s electricity. The balance between fossil fuels and low-carbon energy types presents both a challenge and an opportunity for Greece to further decarbonize its electricity and contribute to global efforts against climate change.

Is Electricity Growing in Greece?
Despite the ambition to increase electricity generation in Greece, recent indicators suggest a decline rather than growth. In 2025, the average electricity consumption per person decreased to 5086 kWh, marking a significant reduction of approximately 1175 kWh compared to the peak in 2008. Similarly, the low-carbon electricity generation per person reached 2533 kWh, showing a minor decline from the record set just the previous year. This stagnation in both overall and low-carbon electricity consumption is a concern, considering the rising demand for clean electricity required for large-scale electrification projects and advancements in technology, such as AI, that depend on reliable power sources.
Suggestions
To bolster low-carbon electricity generation, Greece can expand its already significant solar and wind capacities, learning from successful regions around the world. Countries like Denmark and Iowa exemplify high wind energy utilization, achieving over 55% wind-generated electricity. Greece can emulate these leaders by enhancing wind power infrastructure to harness its natural wind resources. Furthermore, Greece should explore the potential of nuclear energy, learning from nations like France and Slovakia, where nuclear power contributes to more than two-thirds of the electricity mix. By investing in solar, wind, and nuclear power, Greece has the potential to not only increase its low-carbon electricity generation but also secure a reliable supply of clean energy for the future.
History
Historically, Greece's journey toward a low-carbon electricity sector has been marked by fluctuations. In the early 2000s, hydropower saw varied changes in its electricity generation, with notable decreases in 2001 and 2007 and increases in 2003 and subsequent years. Around 2013, solar energy began to make a significant impact, similar to wind power starting in 2020. However, recent years have shown mixed progress, with some declines in wind power generation in 2025, even as solar energy continues to grow. These patterns reflect the necessity of consistent investment and innovation to explore greater expansion in low-carbon technologies, particularly in the face of diminishing fossil fuel use. By steadfastly increasing clean electricity production, Greece can confidently move toward energy sustainability and security.
