The Dakotas will not produce enough electricity to power the nation. The DOE estimated that if we put all reasonable effort into wind energy across the nation, it could provide about 20% of our current utilization. I'm all for it, but I'd prefer to be more realistic and hope that we could get to 10-15% in the next ten years - allowing that even though we continue to increase efficiency, the requirements will grow.
Wind will and should be the first source we turn to when it is practical. It is not practical in much of the south or here in the Southwest, but it is on the High Plains, Texas, parts of Appalachia and the New England Coast.
In the Southwest - including Arizona, southern California, Nevada, New Mexico, and parts orf Colorado - we should be looking at solar in the same way, but it's not as inexpensive, so we are more dependent on the Alternative Tax Credits than states that have a lot of wind.
TIPS is an interesting technology, but it stops at capturing and pressurizing CO2. What do you do with it after that? A few projects (including two in Arizona) use the gas to grow algae for biofuel. That amounts to secondary utilization, but it still eventually winds up in the air. Until there is proven and cost effective sequstration technology - I am hesitant to promote significant expansion of coal while wind is competitive and can take up the slack. I do think we should be ready to put public funds into retrofitting older coal plants to cleaner technologies.
In my mind - the primary goal is to get away from dependency on oil. We don't have enough of our own and we never will and the global supply will from here on never meet the ever increasing demand.
We will need more nuclear power, there is no question in my mind. I don't want to rush into it until we know what we're going to do with the waste, and how we're going to build a national grid to maximize the use of alternatives while using nuclear to strategically handle baseloads. I don't hear many voices talking in these terms yet.
