It seemed like you were saying that because the sun doesn't always shine and windmills are classed as NIMBY in some regions, therefore all renewables are crap. Iceland is one example of a 100% renewable country where the sun doesn't shine and they don't spin wind turbines (I guess because they freeze?).
I was surprised to learn after a little searching just how much geothermal power is already available in the USA, and that it doesn't require an active volcano, but can be developed with a deep pipe 1-2km down towards the mantle. I'm not sure the cost to dig such a hole and operate the plant, but would be surprised if it were higher per unit of energy than the startup costs, maintenance costs and waste disposal costs (for all time!) of nuclear plants. Wikipedia lists geothermal as less than half the cost per kW of nuclear.
Cost of electricity by source
There are a myriad of options to generate renewable power and to store it for base load use. Sun, wind, hydro, geothermal, biothermal and ways we haven't invented or perfected yet like solar fields in space or electricity generated from roads via mechanical vibration or heat transfer. One neat storage story over here in Europe is from Switzerland, who finally finished their massive hydro-electric storage facility under the Alps which will come online next week.
Revolutionary new Swiss 'water battery' will be one of Europe's main renewable sources of energy
Obviously the world would need more renewable generation plants than the number of nuclear plants, but I don't see that as a bad thing. More plants is more redundancy, more competition for solutions, less need to transmit electricity very far distances, and potentially more options for regions or individual homes unreachable by transmission lines. Not to mention more jobs.
I look at it like the internet: we don't have one big router, or even one route from machine A to machine B. We have millions of little routers working together to serve this massive global network. It seems like electricity generation and storage should be moving in the same direction. I think Tesla is launching virtual power plant software for their powerwalls in the USA now? There are a lot of novel solutions to this problem.
