pollution control

We know that burning coal produces greenhouse gases that cause global warming. But it's also a big source of other types of air pollution that can cause disease and even death.

Around the country, dozens of coal-burning power plants are racing to comply with new Environmental Protection Agency rules to keep mercury out of the air.

In Michigan, Consumers Energy and DTE Energy are both spending roughly $2 billion to comply with new air rules.
