This is a publication from the Minnesota Department of Commerce, Division of Energy Resources.

The Division of Energy Resources (DER) is working to move Minnesota toward a sustainable energy future, managing energy assistance funds and advocating in the public interest on energy utility rates and facility siting. We provide information and assistance on energy conservation, energy efficiency, and renewable energy options to residents, builders, utilities, nonprofit organizations, and policy-makers on building improvements, financial assistance, renewable technologies, policy initiatives, and utility regulations.

This consumer energy guide was produced, in part, with funding from the Department of Energy.
