Renewable Energy Credits (RECs) represent proof that electricity was generated from an eligible renewable energy resource.  The issuance or purchase of RECs offsets the generation of emissions that factor into climate change, and provide the financial incentive for development of new renewable energy sources.

The GreenCurrents program allows customers the option to elect to pay a little more on their electricity bills in order to encourage the development of renewable energy sources in Michigan. The purchase of RECs by DTE Energy and others has so far enabled the construction of four wind farms and biomass energy plants in Michigan.
