The Department of Energy was created in 1975. The department protects Oregon's environment by saving energy, developing clean energy resources and cleaning up nuclear waste. To encourage investments in energy efficiency and conservation, the office offers loans, tax credits, information, and technical expertise to households, businesses, schools and governments. The office aims to ensure that Oregon's mix of energy resources minimizes harm to the environment and reliably meets the state's needs. To meet this commitment, the office formulates energy policies, advances the development of renewable energy resources, and evaluates whether proposed energy facilities are economically and environmentally sound. The office also oversees the cleanup and transport of radioactive waste and develops and implements emergency plans for accidents involving radioactive materials. A major focus is the cleanup of radioactive waste at the Hanford nuclear site on the Columbia River in eastern Washington and the Trojan nuclear plant in Columbia County. The office staffs two energy policy and regulatory boards. The Energy Facility Siting Council is a board of citizens that determines whether energy facilities may be built in Oregon. The Hanford Waste Board represents Oregon's interests related to the Hanford site.
