Greece currently generates much more electricity from the sun and wind compared to a decade ago. Yet, its overall foreign energy dependency remains one of the highest in the European Union.
According to the latest Eurostat data, in 2024 approximately 78% of Greece’s energy needs were covered by net imports, compared to an EU average of 57%. The country thus ranks among the most energy-dependent member states. The problem lies mainly in fossil fuels: oil and petroleum products accounted for 84% of Greek energy imports.
The development of renewables has therefore not yet translated into a corresponding reduction in dependence on imported fuels. Natural gas is a case in point. Its domestic consumption increased by 30% in 2024 and by a further 6% in 2025, reaching 70.16 TWh. More than 70% was consumed for power generation.
At the same time, dependence on LNG, and particularly on the US, is increasing. In 2025, the United States supplied 86% of the LNG unloaded at Revithoussa, almost double the quantity compared to 2024. Nor does this trend appear temporary: in June 2026, the 20-year agreement to purchase US LNG from Venture Global, starting in 2030, was doubled to 1 million tonnes per year.
Diversifying suppliers following the Russian invasion of Ukraine was necessary for security of supply. However, the government’s choice to simultaneously invest in long-term gas contracts and infrastructure risks turning an emergency solution into a new decades-long dependency.
True energy autonomy will not come by changing the natural gas supplier. It will come by reducing the need for imported fuels: through storage, stronger grids, the electrification of transport and heating, energy efficiency, and greater participation of citizens and energy communities in clean generation.
