People responded to the request for citation already, but Google ROI will get you a lot of sources. Wind is in fact one of (often the) cheapest options, so the OP was wrong. To add to your point of "we just need more research to make nuclear viable", nuclear has been the most subsidised (also in research funding) energy source, it has not gotten us there over the last 60 years. And regarding adding the cost of battery, this is the baseload myth, actually nuclear power plans are much worse than wind power. Having power plants that don't easily adjust to load is worse for a network than ones that change. There is actually research that shows if your network is large and modern enough (the wind always blows somewhere) you could work with only wind or solar. You could not if you only have nuclear power plants. You then need adjustable loads (Belgium does illuminate all there highways for this reason) .
