Utility companies are reading through the new clean air rules released by President Obama this week. The regulations would cut carbon emissions, especially from coal fired power plants, by thirty percent or more over the next decade.

Tom Glanzer, with Northwestern Energy in South Dakota, says they are trying to understand the impacts…

 

Much of the focus of the new rules is on renewable power sources. Glanzer says Northwestern has been moving that way for years…

 

Northwestern still gets about sixty percent of their power from coal fired plants.

Glanzer says they are already seeing higher costs because of tighter environmental rules…

 

A number of states have banded together to sue the Environmental Protection Agency over the new rules.
