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.
