DTE Energy Foundation

Ypsilanti, MI

Energy is critical to our quality of life and economic progress. DTE Energy is relied upon 24 hours a day, seven days a week, 365 days of the year to produce, acquire and deliver that energy, whether from traditional sources or from renewable and alternative technologies. That makes us, in a sense, a company that never sleeps. At DTE Energy we believe that we have a greater responsibility. We believe that being part of a community means being involved in the fabric of that community. It means being a force for growth and prosperity in the communities that we serve. The DTE Energy Foundation, the charitable arm of DTE Energy, is integral to that mission.
