Three quarters of the nation's electricity comes from hydroelectric powerplants(水电站)，taking advantage of the heavy rainfalls and abundant river system. The rest of its electricity is generated from wind energy，geothermal energy，biomass sources and solar energy.
The electricity agency said that despite a rough and dry year，the country is still ahead of its renewable energy goals.
“We are closing 2015 with renewable electricity milestones that have put us in the global spotlight，”said Luis Pacheco，ICE's electricity division chief.
Pacheco said that when a new $2. 3-billion hydroelectric powerplant comes on line next year，the country's energy generation will even be better.
In March this year，Costa Rica made the headlines when it managed to go on without burning a single fossil fuel for 75 days straight.
Aside from Costa Rica，other countries with significant hydroelectric capacity include Afghanistan，Lesotho and Albania.
Denmark，meanwhile，is the leader in wind power. The country generates electricity from its turbines(涡轮)for 40 percent of its population. On some strong windy days，the country has even generated as much as 140 percent of the energy it needs. Whenever possible，such spare energy is exported，but better storage would transform it into something more valuable.
Another country is catching up with Costa Rica's impressive renewable sources.
A report on Dec. 4 said that 95 percent of Uruguay's electricity now comes from renewable energy. The turn-around is impressive，especially because oil made up most of the country's import in 2000. The country still uses oil，accounting to 45 percent of the total energy mix.
