Costa Rica in Central America supplied 150 days of fully renewable energy to its 4.9 million people, including 76 consecutive days from June 17.
According to the Costa Rica Electricity Institute (ICE) 80 per cent of their electricity came from hydro sources and 13 per cent from geothermal power.
Costa Rica is aiming to be carbon neutral by 2021. The tropical nation has heavy rainfall and volcanoes provide a big source of energy, helping to power the country’s four hydroelectric plants.
The nation is also only 51,100 square kilometres in size – smaller than Tasmania which is 68,400 square kilometres.
Last year, Australia produced 14.6 per cent of renewable energy, up from 13.5 per cent in 2014.
