Iceland is the only country that generates 100% of its electricity through renewable sources, with 81% of total energy use coming from renewables. The country uses both hydro (75%) and geothermal (25%) sources to generate electricity and heat. For primary energy uses, such as transportation and heating, fossil fuels account for only 21% of energy use. The country's renewable energy sources are largely due to the island sitting on a very active spreading zone, where the Eurasian and North American tectonic plates are moving away from each other.
