According to C. Lowell Miller of the Department of Energy, almost 60% of US energy production comes from coal, and concerns over the security of energy supply mean that isn't likely to change anytime soon.Mr. Miller is the Director of the DOE's Office of Hydrogen and Clean Coal Fuels.He
notes that the US has more coal than any other country on earth, and "When the DOE
looks at what its energy resources are within the continental United States , from a security point of view, that much energy cannot be ignored.Which equates to a lot of pressure on our office to go ahead and develop the technologies to utilize the coal, while at the same time achieving all of these environmental objectives."
The urgency, he
says, is increasing.
