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.
More about renewable sources:
Renewable energy is used from four main sources: sun, wind, water, and geothermal heat.
By 2012, 80 countries operated wind farms totaling to over 225,000 wind turbines in use.
in 1904, Larderello, Italy was the first community to produce electricity through geothermal energy.
