Costa Rica is much more than a lush, green tourist paradise; it’s also a green energy pioneer. The small Central American nation has generated 100 percent of its electricity from renewable sources for the past 113 days, and the run isn’t over yet. The country, which draws clean energy from a variety of renewable sources, still has its sights on a full year without fossil fuels. Costa Rica could be on track to match the record set with its renewable energy production last year, which accounted for 99 percent of the country’s electricity. That included 285 days powered completely by renewable sources, according to the Costa Rican Electricity Institute. Costa Rica is able to take advantage of a multitude of renewable energy sources because of its unique climate and terrain. Most of the nation’s renewable energy comes from hydropower, due to its large river system and heavy tropical rainfalls. Solar, wind, biomass, and geothermal energy also play key roles. The tropical nation aims to be free from fossil fuels in just five years. With hefty investments in geothermal energy projects and a forecast for more heavy rains in the coming years, that goal could be accomplished even sooner than originally planned. http://inhabitat.com/costa-rica-celebrates-113-days-of-100-percent-renewable-energy-and-counting/
Did they mentioned, if they use automobiles which I believe they do. I don't think they will use horse and buggy to transport their coconut oil production to the market.
Yes, they probably also had a few natural gas or oil furnaces running for heat. Keep in mind what the article said - that they "generated 100 percent of its electricity from renewable sources for the past 113 days" not that they used no other energy at all.
They might not have much need for fossil fuel heating - doesn't seem to get much below 50F, and that briefly, anywhere or any time in the country. Such brief and occasional chill would be handled with electric heat more efficiently than with installed furnaces. That leaves planes, cars, trucks, and buses as sticking points.
