Greece breaks into global top ten for renewables

The report analyses electricity generation data from 215 countries worldwide for 2025. In particular, the findings indicate the following:

• Greece ranks third globally in terms of the share of solar energy in the electricity generation mix, reaching 22%, up from 20% in 2024. Hungary ranks first with 27%, followed by Chile with 25%. The global average stands at 8.7%, while the EU average is 13.1%. In terms of per capita solar electricity generation, Greece ranks sixth globally, with approximately 1,300 kWh per person per year.
• With regard to wind energy, Greece ranks ninth worldwide in terms of its share of total electricity generation, at 20%. The global average is 8.5%, compared with 17.1% in the EU.

The report further highlights that, globally, clean energy sources expanded at a pace sufficient to meet all incremental electricity demand in 2025, thereby preventing any increase in fossil fuel-based generation. Notably, 2025 marked the first year since 2020 in which fossil fuel electricity generation did not increase, and only the fifth such year in the 21st century.

China and India, historically the largest contributors to the growth of fossil fuel-based electricity generation, recorded declines in 2025. In both countries, record additions of clean energy capacity more than offset increases in electricity demand.

Solar energy alone accounted for three-quarters of the net increase in global electricity demand in 2025, with growth 18 times greater than that of natural gas, the only fossil fuel to record an increase during the year. Global solar electricity generation is now broadly equivalent in scale to the total electricity demand of the European Union.
