CROATIA-EU-ENVIRONMENT-ENERGY-ELECTRICITY

A picture taken on February 22, 20107 shows ducks and swans swimming in an artificial lake near the small hydro plant on the Korana river in Karlovac, Croatia. Croatia produces up to 75 percent of the electricity it needs while the rest is imported. Ecological activists fear that the country's pristine rivers could be devastated by dozens of planned small-scale plants and warn against their far-reaching negative impact while the situation is, they say, the most critical in Karlovac, the "Town on Four Rivers". / AFP PHOTO / Damir SENCAR (Photo credit should read DAMIR SENCAR/AFP via Getty Images)
