Well, the interesting thing is large scale solar plants don't need PV, they can use CSP--which is just a bunch of mirrors focusing a field of sunlight on a tower to super heat it. The tower, if it uses molten salt, can actually provide 12+ hours of energy even when the sun is down, so it can actually handle base load. And the mirrors, as far as I know, don't use any rare earths. The downside is that the system needs some large scale mechanical alignments, so it's overhead is more--also, it's much more dependent on radiance, so it can't be built in certain areas without a lot of sun. But where CSP can work? I believe it's strictly superior to PV. So in the South, Solar might still end up being king.I was reading that some of the newest production wind turbines can pay for themselves in as little as 8 months.
That seems like it's damn near a tipping point.
Solar seems relatively pointless until we can go straight to organic solar cells. Regular photovoltaic materials seem to use too much rare earth stuff to ever be truly wide scale.
Which is only one side of the medal.The biggest problem for Nuclear is the ignorant NIMBYs that refuse to let a plant be built within 100 miles of them. Since they cover the entire country that makes it tough to get anything done.
O might be wrong, but I don;t think the waste produced in normal operations is suitable for weapons. The old nuclear plants were designed to be able to produce weapons grade plutonium but the reactors have to be run in a slightly different way to do it.A lot of our current nuclear plants were built to produce waste that the govt. bought to make weapons, so many of them aren't really competitive.
Yea, there's just CO2 and global warming, if you believe in that.The point is just how good nat gas currently is and may remain for decades. Barring all the aquifer pollution shit which i personally don't believe, you spend a couple weeks and maybe a million developing and pad, fracking, and hooking up a pipeline and then sit back and collect 10mil plus in nat gas and other petroleum liquids... and you can do that one like 5 mile grids for entire states.
There's no mine reclamation, mountaintop removal, acid mine drainage, billion dollar thousand year nuclear waste disposal bungled bullshit, or possibility of ultimate catastrophe.
I think it's amazing it's competitive enough to low ball nuclear plants that are already in action, especially when Obama just finished cleaning house on coal fired plants.
