Croatia's Renewable Energy Sources Generate Over 5 TWh for First Time
In 2025, Croatia's renewable energy sources generated over 5 terawatt hours (TWh) for the first time, comprising 26.6% of the country's total electricity consumption. Hydropower remained the largest source, despite a year-on-year decline, while biomass and biogas showed notable growth. Overall, renewables accounted for 52.6% of electricity supply, coinciding with a significant reduction in fossil fuel generation.

In 2025, Croatia's renewable energy sector achieved a historic milestone, with solar, wind, biomass, and biogas generating over 5 terawatt hours (TWh), accounting for 26.6% of total electricity consumption. This marked the first time that these sources collectively surpassed all other generation technologies.
Renewables, including hydropower, supplied 52.6% of Croatia's total electricity, with total consumption reaching 19,326 gigawatt hours (GWh), a 1.01% increase from 2024. Notably, biomass and biogas plants showed a 5.5% growth in the second quarter, providing essential dispatchable capacity.
Despite this growth, Croatia imported 3,137 GWh of electricity, primarily from Hungary and Bosnia and Herzegovina. Hydropower remained the largest single generation source at 5,022 GWh but fell by 18.4% year-on-year due to unfavorable hydrological conditions. The rise of renewables coincided with a 51.6% decrease in fossil fuel generation.
