It's never an "or" thing, it's an "and" thing, we need both. The more renewable we have, the better, but for a base-load it's hard to have this everywhere and batteries are far from an ideal solution. We don't need nuclear to replace wind/solar, we need it to replace the oil/coal/gas which we can't seem to get rid of for that base-load.

And Texas has a lot of sun during moments with peak usage (aircos) - so it you'd have to be an absolute moron not to see the advantages there, but for example in Germany they're going backwards here, they use coal and gas to replace nuclear - in a time where our primary focus should be on producing as little CO2 as possible - which is just another level of stupidity.
