I hope that we can pursue both renewable and nuclear at the same time, but I understand that in many ways renewables are a better deal if we have limited resources. If wind and solar become the primary sources of electricity we'll either need storage or some other source of power to fill in the gaps when the sun isn't shining or the wind isn't blowing. Also, high-heat reactors can replace fossil fuels in many industrial processes. So each has their strengths and weaknesses and can be used in complimentary ways.

I honestly haven't looked into uranium mining much, but I do know that solar panels require mining of certain rare-earth minerals, and most wind turbines are made of composite materials derived from petroleum. Storage of waste is pretty well solved, and spent fuel can be re-processed to extract the remaining useable fuel, or burned up in fast reactors.
