The Current Clean Energy Thread

[Crono]

In the interest of not derailing another topic, I've created this one to discuss this between Entroper and Myself:

The cost benefit of going nuclear fission as opposed to oil or coal
burning far outweighs whatever tax dollars might get spent to help
subsidize their construction. Sure, subsidize alternative energy
sources too, but don't block the cleanest most efficient way of
producing energy we have because the government helps foot the bill a
little.

I'm not blocking anything, but nuclear is neither the cleanest nor the most efficient energy source. If it were, I'd be all for subsidizing it.

 

I am just curious, based on current available technology (read: Not emerging technologies like fusion and hydrogen), what do you think is the best way to go about creating clean, efficient electricity to power our grid.
Obviously, I believe that nuclear fission is the best current option.  Its been 30 years (or more) since the last Nuclear Power plant was built in the US.  In those 30 years, there hasn't been a major nuclear disaster in any US plants or in any of the numurous European plants.  Additionally, waste disposal has also improved greatly, virtually eliminating the risk of waste contamination in the environment.
Nuclear power produces steam as a bi-product.  Thats the only "emission" into the environment.
