Greece’s energy mix is currently undergoing a rapid transition from a heavy reliance on domestic lignite (brown coal) toward renewable energy and natural gas. In 2024, clean energy (renewables and large hydro) met 50.5% of the country’s electricity demand.

Wind & Solar accounted for approximately 44.4% of demand in 2024. Solar PV capacity specifically reached 9.6 GW by the end of 2024, doubling in just two years. Natural Gas provided 37.5% of demand.

The updated National Energy and Climate Plan aims for renewables to cover 75% of electricity generation by 2030 and 95.6% by 2035.

Greece is rapidly positioning itself as a key European green hydrogen hub, targeting 1.7 GW of electrolysis capacity by 2030 and 30.6 GW by 2050 to decarbonize heavy industry and transport. Backed by significant solar and wind resources, the nation enacted its first dedicated hydrogen law in July 2025 (Law 5251/2025) to regulate production, transport, and storage, including a 25-year Hydrogen Producer Certificate. Hellenic Hydrogen, a joint venture, is developing a 100 MW electrolyzer in Northern Greece, while the H2 CRETE Valley Project focuses on green H2 and ammonia production.
