DTE Energy says it's committed to reducing greenhouse gas emmissions, but says coal will continue to be an important fuel for energy generation.
President Barack Obama wants carbon emissions from coal-fired power plants cut by 30 percent by 2030.
DTE Energy says 10 percent of the electricity generated for customers in southeast Michigan will come from renewable sources by the end of this year.
It also believes a balance of coal, natural gas, nuclear and other renewable sources of energy is needed to protect customers from high prices, and ensure the reliability of the energy supply.
The Michigan League of Conservation Voters applauds the President's proposal, but says the challenge will be to make sure people tell the EPA and their legislators that this is an important issue to them.
