For some people, sustainable energy means renewable energy, like wind and solar. Energy sources that can’t be used up. Some people think sustainability is about conservation—using less energy, less water, and making fewer trips in the car. Other people talk about air quality and wildlife.

For us, sustainability means these things and more. It’s about energy like forests and rivers. Sustainability is about people. It’s about being responsible and being honest. It’s about future generations. Sustainability isn’t just something we do. It’s everything we do—from keeping our employees trained and safe, to keeping the lights on in Michigan for centuries to come. It’s about leaving the world a better place than we found it.
