Gas turbines are not that expensive in capital. Instead they cost a lot to run, since they use gas that's much more expensive than coal. (Nevermind Uranium or wind or the sun.)

A big part of US climate strategy seems to be to install a lot of wind and solar power and fill the rest with natural gas, phasing out coal. Keep the nukes that are there. That's possible since in the USA, natural gas is cheaper than in many other places.
