Costa Rica says it has been powering its grid using 100% renewable energy, mostly from hydro and geothermal, for the first three months of 2015.


And in 2010 it was reported that about 13 per cent of the Latin American nation’s energy came from geothermal.

Now, Costa Rica is in the process of adding several big new geothermal plants, after a $US958 million proposal was approved by the government in mid-2014.
