Even assuming we build enough wind/solar to supplant existing coal/gas/oil generation, the unsolved problem is storing that energy for use at night, or on cloudy or windless days. Batteries are the only feasible thing in most places, and they are not available in the quantites needed for such an undertaking, and they are mostly made in Asia.

How much would we need to invest in batteries (mining/refining the raw materials, and actually building them, replacing them as they wear out, dealing with the recycling/waste, etc.) compared to the cost of a standardized modern reactor design.
