Norway used 896 PJ of energy in 2010, which accounts for 21% of the energy used in the Nordic region.
Due to the high volume of electricity consumption by the aluminium industry and in space and water heating in buildings, Norway is second only to Iceland in electricity consumption per capita. Electricity produced in Norway however is almost entirely renewable, based on significant hydroelectric resources.
Transport accounts for a significant share of energy use in Norway, due to a population of only about 5 million spread over a large country. Norway has a electric train fleet and the capital city of Oslo is a world leader in the sale of electric vehicles.
