All modes of renewables could be used to power the US. Geothermal, wave, tidal, wind, solar - hell I think the best option would be to build a SBSN. It is completely feasible to transition the home owner to be self sufficient energy wise. We could use oil then to power other things, or for manufacturing. It increases the livelihood of that resource, assuming that resource doesn't have an ill effect on the planet which I don't believe, but I don't know. So if the question is still out there, then we still burn oil and coal, albeit the sun would be powering the grid. For sure, it can power residential homes.
But it makes sense that the transition will be made once financially it makes sense. Once it costs too much energy to harvest x amount of energy, then the market will change and go to renewables. Already there are concept electrical cars being made by Audi I believe in response to Tesla. Tesla has successfully built basically a home battery. It stores electricity from whatever method you want to use, and can obviously power a home. So I suppose the market will shift once the numbers don't add up.
