Skellefteå has been a pioneer of renewable energy since the early 1900s when municipality-owned power company, Skellefteå Kraft, was founded. The company, one of the biggest power suppliers in Sweden, boasts an 80% share of renewables and has a goal of transitioning to 100% renewables by 2040. The city also is host to a leading CleanTech cluster. This cluster houses numerous companies specializing in environmental technologies, including bioenergy developers, basic and noble metals recyclers, and leading-edge companies that are developing wind technologies for cold climates.
