Hiya,
We can have it ALL ways! PV on every roof AND solar in the southwest -- and wind in the middle of the country and offshore, and biomass, and biofuel, and wave, and tidal, and geothermal, and small scale hydro power...all of these together in a mix that best suits the area can and will be the long term solution for our energy needs.
Nuclear is not a solution.
