MIT study "The Future of Coal"

I just downloaded the study made by the MIT group about the future of coal in a carbon-constrained world (released last week). The study evaluates the technologies and costs associated with the generation of electricity from coal along with those associated with the capture and sequestration of the carbon dioxide produced coal-based power generation.

Coal-based energy plants produce most of CO2 emissions in US and within the next 5 years most of the US plants will be 40 years old of productive life (average is 50), besides the 2 new plants that TXU (Texas utility company) is going to build.

I think the sequestration of carbon is a great idea, but do we want to continue with coal-based plants? I think we need to push for more research on renewable energy generation and also on incentives.
