Hydro is pretty horrible for environment actually, it smashes river ecosystems to fuck. Same as wind power basically blenderises bird life. The irony of climate environmentalists is how massively clueless they are about the actual environment. The energy source they superstitiously loathe the most is actually the best for the environment because fossil fuels result in a net increase in the earth's biological carrying capacity. But the dumb shits do not science, so they will never understand. It is sad really.
Good grief, you were actually serious.
I knew about the effect of dams in the 1970s. I was a member of the Saco River Salmon Club and one of the things we did was get dams torn down.
The situation is painfully simple. We need energy, so what makes sense is to do as little damage as possible generating it. I'd like to see us use less energy, but Americans have their heads up their butt.
In any case, the energy will be coming from Hydro Quebec, which was built some time ago. The damage is done, and compared to anything else, it's a hell of a lot cleaner and doesn't emit enough carbon to be worth mentioning.
What the US needs is a power plan that will lower GHG emissions while doing minimal damage. Intellectually, that's easy. Add tough efficiency standards, develop a Smart Grid, and build power supplies that don't emit carbon. If we are doing a clean sheet design exercise, that means some nuclear plants near some of our large cities. We would want to work up some new plant designs. A nuclear plant is always a balancing act between power and safety, but it wouldn't be hard to improve safety a lot over the old designs and still get reasonable output.
In case you didn't know, nuclear waste disposal is a solved problem. The politics are a nightmare, but we know how to do it.
By know you should have guessed what I am going to say next. We have serious problems that are entirely solvable. Somehow we need to get past the politics so we can work on climate change, as well as the ancillary issues.
You simply can't generate power without generating some problems along with it. The trick is to manage those problems, to keep the level of damage as low as possible.
