What Country Powered Itself Entirely On Renewable Energy For 75 Days?

The idea of an electricity grid powered entirely by renewable energy may seem like a utopian dream, but one country has recently achieved it, albeit briefly.

That would be little Costa Rica, which claims to have powered itself using only renewable energy for 75 days.

This was largely thanks to heavy rainfall, which powered four hydroelectric plants during that period, the state-run Costa Rican Electricity Institute told The Independent.

No fossil fuels have been used to generate electricity since December 2014, authorities say.

Located between Nicaragua and Panama, the small Central American country already has substantial renewable-energy infrastructure, and hopes to move away from fossil fuels permanently.

Last year, Costa Rica got 80 percent of its electricity from hydro sources, and another 10 percent from geothermal sources.

The World Economic Forum ranked Costa Rica second in Latin America--after Uruguay--in electricity and telecommunications infrastructure in its 2014 Global Competitiveness Index.

Projects to expand geothermal generating capacity are also in the planning stages.

The national government approved $958 million in funding for these geothermal projects last year.
