Ladies and gentlemen, a round of applause for Costa Rica – this Central American nation has been running on 100 percent renewable electricity for at least 76 consecutive days. This follows on from 150 other days already this year wherein it has only used geothermal and hydrothermal power generation. Last year, a whopping 300 days were fossil fuel-free in terms of electricity generation. [...]
Normally, about 7 percent of its electricity is generated by fossil fuels. Fortunately, particularly heavy rains recently have supercharged the nation’s four huge hydroelectric dams recently, rendering fossil fuel combustion unnecessary. (Weirdly, the surge in rainfall may be attributable to climate change itself.) [...]
Iceland – a far wealthier (GDP $47,500 per person) but far less populous (323,000) country, is comparable in terms of how it produces energy. Like Costa Rica, it has almost no need for other power sources, including wind, nuclear, biomass or fossil fuels.
