Norwegian electricity production is dominated by hydropower. Hydropower is one of the only renewable energy sources that can be stored, and the generators can easily regulate output from one minute to the other. Thanks to the common Nordic grid, Norway’s large reservoir capacity can be used to store and regulate a fluctuating supply from renewable energy sources like wind and solar in neighbouring countries.
Norway also has significant untapped wind and bioenergy resources, which could prove useful for future domestic and international demand. In 2012 Norway entered a joint green certificate scheme with Sweden, which is expected to lead to an increase in wind and hydropower capacity in the country.
