(1,825 posts)Yes - hydro is very cheap. However, do you really think that we're going to be able to build many more dams? Most of the really good locations for dams already have dams in place. Besides, your own environmental community opposes dams almost as much as they oppose nuclear power. In fact, they want to rip out the dams that we have. Look at those that want to tear down the Hetch Hetch dam and return the valley to what they "think" will be another Yosemite. Fat Chance. After spending so many decades under water, that valley is going to be no Yosemite.
There's a very limited number of sites for geothermal. The good ones that have dry steam like The Geyers have power plants. The "wet" sites have to deal with all the toxic crud that falls out of solution when the energy is extracted and the temperature drops.
Wind power just doesn't have the capacity factors. You are lucky to get a 25% capacity factor for wind. So the cost should be adjusted accordingly.
Biomass is another one that people don't want in their back yards.
Besides, the 20 or 30 cents difference between those methods and nuclear is a drop in the bucket. Solar has cost differentials of a dollar or two, and that's with the subsidies that are going to be going away.
Tighten your belts solar proponents; it's going to get bumpy.
But just remember; it's always darkest just before it goes totally black.
