It’s been 75 days since Costa Rica’s power grid last had a sip of petroleum. Thanks to heavy rainfall at the start of the year, the Central American nation has been able to provide 100 percent of its energy needs via renewable resources. This certainly represents a major milestone in green energy production but there’s no guarantee that other nations will be able to replicate this feat or that Costa Rica’s renewable energy scheme is even sustainable.
It doesn’t hurt that Costa Rica has invested heavily national power grid. 80 percent of Costa Rica’s entire energy budget comes its four hydroelectric plants with another 13 percent derived from geothermal stations. Solar, wind and fossil fuels round out the remaining 7 percent.
