Amelia Cerling Hennes

“We all do better, when we all do better.” — Senator Paul Wellstone

Amelia serves as Clean Energy Economy MN’s (CEEM) Managing Director. In this role, Amelia serves as a trusted liaison between staff and the Executive Director. She also serves as a key contact and spokesperson both internally and externally while providing strategic guidance and direction for the entire organization. Amelia is a storyteller at heart and has embedded the use of stories to help connect the dots between Minnesota lawmakers at all levels of government – and the economic benefits created by clean energy across the state.

Amelia holds degrees in broadcast journalism and Middle Eastern studies from the University of Minnesota-Twin Cities and serves on the Minnesota Solar Industry Energy Association’s (MnSEIA) board of directors. Amelia has nearly 15 years of experience in her field, and her career is rooted in her broadcast television background where she served as a TV anchor, and her time at the Minnesota Senate.

When she’s not sharing stories about clean energy, you can probably find her at her local bakery. Amelia is a big fan of exploring new foods and restaurants across the Twin Cities, yoga, and traveling to new places near and far with her friends and family. As a lifelong Minnesotan she is also a strong advocate of winter and is using her creative juices to figure out how to make the most out of the season with two little kids!
