About the association

The economic and interest association Renewable Energy Sources of Croatia brings together producers of electricity from renewable sources with 80% of the total installed capacity. In Croatia, these are also the only projects from renewable energy sources that we have. In the last 15 years, investments in renewable energy sources in Croatia have been carried almost exclusively by the private sector.
