In 2024, Greece's electricity consumption is nearly evenly split between low-carbon and fossil energy sources. More than half of the electricity comes from clean sources, with approximately 51% being generated from low-carbon options such as solar, wind, and hydropower. Among these, solar and wind each provide a little over a fifth, marking significant contributions to the country's clean energy mix. On the other hand, fossil fuels account for around 48% of electricity generation, with natural gas being the dominant fossil source at over 41%, and coal comprising about 6% of the mix. Net imports are minimal, at just over 1%, indicating a strong reliance on domestic production.
Greece has significant potential to further increase its low-carbon electricity generation. Expanding existing wind and solar capacity is a natural first step, as these sources are already major contributors to the electricity mix. Looking at international examples, Greece can draw inspiration from Denmark's substantial wind generation, which makes up 59% of their electricity. This demonstrates the potential for an even greater expansion in wind energy. Additionally, considering regional similarities, Greece could benefit from insights into nuclear energy utilization observed in Bulgaria and Slovakia, where nuclear power supplies 42% and 60% of electricity, respectively. A diverse mix that includes a stable nuclear base could significantly enhance Greece's pursuit of a low-carbon electricity future.
Reflecting on Greece's historical journey with low-carbon electricity generation reveals key developments across several decades. In the early 1980s, hydropower experienced some fluctuations with a notable decline in 1983. Through the 2000s and into the 2010s, hydropower generation saw both growth and intermittent reductions, with a remarkable increase of 2.6 TWh in 2021. The 2010s also marked the rise of solar energy, with substantial increments beginning in 2013 and continuing with consistent growth through 2024. Wind energy made a notable advancement in 2020 with an increase of 2 TWh, demonstrating Greece's commitment to expanding its low-carbon electricity options. This historical trajectory reflects Greece's gradual yet steady move toward a more sustainable electricity sector.
