Lots of concrete in a nuclear plant seems like a small price to pay for providing energy for decades.
Interesting footnote I offer here, I watched a construction site the other day with huge earthmovers, scrapers, and dozers, as they worked to cut and fill along a new road being built. I tried to visualize the machines running on batteries or solar or wind, and I concluded again that deisel made from oil is pretty efficient and reliable.
The thing is, the total thermal efficiencies of those engines is actually quite low. That is to say, very little of the power of the gasoline is transformable into usable energy by the machines - 20% at best according to some information discussed earlier in the thread.
In many cases electric motors exist that are as powerful as many of the gasoline that you see - they just require more efficient storage technology. That's why you see me going on about it so often.
Still, you will see that I did mix nuclear in there. I believe that there are ways to make it safe and that science can overcome some of the problems. And the energy output is quite large.
One thing to ponder - with greater efficiency gains in our electronics, we have often noticed a drop in the power necessary to run them. It won't be long before our computers are in many ways so small that solar and wind power would be ideal for powering many things which today suck off of the grid. I think solar and wind are technologies that individual people can invest in and use - this allows those who seek a cleaner environment to take direct action, instead of getting the government to do it for them. One would think that you would be behind this position fully - self-sufficiency for the homeowner, at least in terms of energy.
