Again, they aren't cheaper when you compare to output.
Just to put things in perspective. Solar can do roughly 50W per m2 at best and I am being generous.
Nuclear does 1000W per m2.
Solar is not even close to being able to deliver stable energy so you would have to factor either coal, nuclear or oil into the mix too to provide stable delivery.
Renewable can't deliver the needed energy not even close. Less than 1% right now and not even close with anything like fuel cell technologies or distributed grid systems which would be very very very expensive.
Nuclear whether you like it or not is cleaner, more stable, cheaper and more scaleable.
You will realize this soon enough.
