But transmitting power over long distances incurs power losses. Part of the big push towards renewable power is that you can make generation more localized, because individual generators are easier to set up. If you have to start transmitting that power over long distances, you're going to end up with huge inefficiencies.
I think we could help out of power generation system a lot by building standardized nuclear generators. Much the way we link up a lot of solar panels or wind turbines to generate power, we should use similar methods to build standardized nuclear generators. It would be much easier to ensure safety if they were all using the same design, and it would be much cheaper to deploy. Areas could buy generators that fit the capacity they require.
The reason that wind and solar generation is becoming so popular is because we have the generators pretty much figured out. Installation is pretty simple. If you want to build a nuclear plant, coal plant, gas plant, or hydroelectric dam, it's going to be 10+ years before you pass all the regulatory hurtles and get the thing built. And it never costs what you originally estimated, because you design a new plant every time and run into unexpected problems. If you could just order a bunch of standardized generators, link them up to the grid, you could increase capacity much better. I realize it would be a little more complicated in practice, but there has to be a more efficient way of building power stations than our current methods.
