Croatia has around four million inhabitants and rich potential for renewable energy and energy efficiency. In 2016 the country imported 53.3 per cent of its total primary energy supply, compared to an EU average of 55 per cent. Croatia produces oil and gas but unlike most of its Western Balkan neighbours, it no longer has its own coal reserves.
Croatia produces only about half of its own electricity, depending on hydrological conditions. Most of the electricity generation capacity is owned by Hrvatska Elektroprivreda, the state-owned electricity group. In 2018, 58.6 per cent of domestically generated electricity came from hydropower, 10.9 per cent from coal, 17.4 per cent from oil/gas, 10.1 per cent from wind, 2.4 per cent from biomass and 0.6 per cent from solar. Krsko nuclear power plant in Slovenia, of which HEP owns 50 percent, also contributes to Croatia’s electricity supply but is counted under imports in the statistics.

Although Croatia has made some progress in using its wind potential, solar and solar thermal are underused compared to the obvious potential in this very sunny country.
| Source | Solar PV | Wind |
| IRENA Cost-competitive potential | 3173 MW 4309 GWh |
14384 MW 28317 GWh |
| SEERMAP Decarbonisation scenario (2050 minus 2016) | 1839 MW 1837 GWh |
3857 MW 7215 GWh |
| SEE-SEP The EU Road scenario | 6950 MW 11830 GWh |
3200 MW 8450 GWh |
Renewables and energy efficiency development was for years held back by small renewables incentive quotas for support for wind and especially solar. In line with EU State aid rules, Croatia has now switched to auctioning and feed-in premiums rather than feed-in tariffs, but delays in adopting the implementing legislation and adopting new energy and climate strategies created uncertainty regarding the country’s future plans.
Much time and resources have also been lost on pushing outdated projects such as the 500 MW Plomin C coal power plant, to be run on imported coal, the 450 MW Peruća gas power plant, and large-scale hydropower projects in sensitive locations such as Ombla and Kosinj. The first three have now been cancelled after civil society campaigns highlighted their weaknesses. However a highly unpopular and weakly justified floating LNG terminal on the island of Krk is still planned, with financial support from the EU.
Croatia still has plenty of potential for energy efficiency improvements, especially in the residential sector. Its energy intensity was 26 percent above the EU-28 figure in 2017.

In the air tonight: visualising SO2 emissions from coal power plants in the western Balkans
Grasping what a 600% breach of allowed SO2 emissions means is not an easy job, but our data visualisation does just that. In addition to choking the communities where coal power plants are located, SO2 pollution from the Western Balkans often reaches as far as Russia and the Black Sea Coast to the east and Germany to the West!

The Balkans are decarbonising, why aren’t Serbia and Bosnia?
Despite this deadly legacy, just two years ago, all the Western Balkan countries except Albania still planned to build new coal power plants. Since then, three out of five have abandoned these plans. The region has split, creating a two-speed energy transition.

ContourGlobal finally quits Kosova e Re coal plant
ContourGlobal is quitting the planned 500 MW Kosova e Re lignite power plant project in Kosovo. The company stated that it is now impossible for the project to meet the required milestones, citing, among others, the recent formation of a government led by a Prime Minister publicly opposed to the project.
