A new report warns that Wisconsin’s economic competitiveness could be at risk if the state doesn’t diversify its electricity sources.

The Badger State is already burdened by the second highest electricity prices in the Midwest, with only Michigan customers paying more on average.

Those rates are likely to climb faster than inflation and prices in surrounding states in the next decade due to Wisconsin’s dependance on coal-burning power plants, according to Gary Radloff, director of Midwest policy analysis at the University of Wisconsin-Madison’s Wisconsin Energy Institute.
