Seems like a false dichotomy to me.

We cannot survive on either nuclear or renewables alone. We need every form of energy we can get our hands on, anything practical.

Eventually even people who think that fossil fuels aren't going to destroy the earth are going to have to deal with the reality that there are limited resources on this earth that are easily accessible. Thing is, energy isn't a luxury; it's a requirement for life. We need energy for nearly everything we do, and there is no shortcut or cheat code. We need energy to eat, we need energy to rest, we need energy to make it through summers, we need energy to make it through winters. Without enough sustainable energy in whatever form that takes, there will be a genocide.

So if there's a form of energy we can make use of, we must. If it's going to be energy positive, we need it.
