This debate is much like the debate on taxing internet sales. Bottom line is the states and the fed are looking for additional revenue sources without having to provide a service to earn it.
You can dress a pig up and paint it with lipstick, but in the end it is still a pig.
you want a tax on gasoline. make it 25 cents per gallon and earmark it as a prize for the developer of the best alternative energy solution. ANd for petes sakes bring nuclear energy back on to the grid. That is if you want to be like europe.
One of the big problems with nuclear energy Bt, is that people do not want it near them. TVA tried a number of times to build new nuclear reactors in different areas of Tennessee, even in areas where people "supported" nuclear energy as an alternative energy resource. The problem they discovered was that even people who "support" the use of nuclear energy become some of the most vocal anti-nuclear energy folks when it is in their backyard. It seems to be one of those energies people support in theory, if you could place all the reactors on the surface of the moon!
The second major problem with them is that they don't make money and private companies run away from them unless they can receive large government subsidies. When the United Kingdom privatised her energy sector (which was almost entirely publicly owned in the 70's) they found almost no interest in the nuclear power plants. Those that did show interest wanted heavy government involvement.
The last problem is that they do have waste. It is true that they do not release the carbon dioxide of other power plants (and in fact newer plants release far less radioactive material into the air than current coal-fired power plants), but the waste nuclear power plants leave behind is solid waste and is an extremely nasty and harmful byproduct.
I think it is an interesting and probably superior alternative. Yet, far from a perfect solution.
