"I think we both think carbon sequestration, geological carbon sequestration is a joke," says Kennedy.

"I appreciate that. He's right about one thing. It's true," says Blankenship.

The process take carbon dioxide emissions and puts them in the ground instead of letting them get into the atmosphere. AEP's Mountaineer Plant in Mason County is in the early stages of putting it into practice as millions are being invested in the plant. "I think maybe they don't understand what we're talking about, don't understand the implications. We're going to have some requirement to reduce carbon dioxide emissions," says Tim Mallan, Environmental Affairs Manager for Appalachian Power.

"What they're saying is something else has to be done. Something better has to be done. I agree with that wholeheartedly. This is all we have right now," says Gov. Joe Manchin, D-West Virginia.

Mallan says carbon sequestration is not an established technology yet, adding it needs more development as scientists look to the future to reduce carbon dioxide emissions.

"It's time to take chances, and try to develop the technology that's going to be needed," says Mallan. He believes the technology will eventually work, but the big question could be whether the process will be economically feasible.
