As of 2025, Greece's electricity consumption is heavily reliant on fossil fuels, with more than half of its electricity generated from these sources. Specifically, gas represents nearly half of the entire electricity mix, which starkly contrasts with the needs for reducing carbon emissions. In contrast, low-carbon or clean energy sources contribute to almost half of Greece's electricity generation. Wind and solar energy make significant contributions, with wind accounting for about a fifth and solar almost a sixth of electricity generation. Hydropower contributes a modest share, while biofuels represent a small fraction of low-carbon electricity. The stark reliance on fossils, which includes gas, coal, and oil, highlights an urgent need to boost the existing clean energy framework to combat climate change and ensure a sustainable future.

Is Electricity Growing in Greece?
Examining the broader trends, electricity consumption in Greece appears to be on a downward trajectory. As of 2025, individual electricity consumption stands at 5,127 kWh per person, a notable decline from the peak numbers witnessed in 2008. This dip of over a thousand kWh per person signals a concerning reduction in electricity growth—especially critical in a world driving towards electrification and AI advancements. Specifically, low-carbon electricity generation, which is fundamental in transitioning to a green future, has also seen a recent reduction compared to its record figures of 2024. This must be quickly reversed; Greece needs to aspire for robust growth in clean electricity generation to power its aspirations sustainably.
Suggestions
To bolster low-carbon electricity generation in Greece, expanding wind and solar capacities should be prioritized based on their strong current performance. Looking at successful regions can provide invaluable lessons: countries like Denmark show the potential of wind energy, where it accounts for 60% of their electricity. Nearby countries like Bulgaria and Slovakia demonstrate the significant role that nuclear energy can play, with Bulgaria achieving 40% of its electricity from this reliable low-carbon source. Given Greece's natural resources for solar and wind, complemented by insights from countries leading in nuclear energy expansion, Greece is well-positioned to enhance its clean energy portfolio significantly.
History
Historically, Greece's low-carbon electricity generation has ebbed and flowed, with significant trends noted over the years. In the early 2000s, there was variability in hydropower, with fluctuations like notable declines in 2001 and 2007 but gains in other years. The 2010s marked a turning point with the introduction and growth of solar energy from 2013 onwards, a crucial step towards diversifying the clean energy mix. Wind energy saw a significant boost from 2020 but experienced a setback in 2025 alongside solar. While hydroelectricity remained erratic, the general trend in recent years seemed to push towards solar and wind. It is imperative for Greece to stabilize and grow this trend, securing a future with strong low-carbon energy generation, free from the shackles of unpredictable fossil fuel markets and environmental degradation.
