The island nation has by far the highest per capita electricity consumption level in the world, mainly due to the aluminum industry. However, Iceland’s electricity is completely climate-friendly, generated solely from hydroelectric and ­geothermal energy. Geothermal heat also enables bananas to grow despite icy temperatures – in greenhouses heated by hot water from underground.

Renewables as a proportion of electricity generated (2018): 100%

Electricity consumption per capita (2018): 54.6 MWh
