Wind and sun are renewable. Turbines and solar farms are rebuildable. If we have the transportable and dense energy surplus to rebuild them.

*Looks like all steel production is electric,so it could be powered from renewables.
*Same for aluminum.
*So far,as I've looked,glass production(for PVs) is based upon a gas-furnace melt.Perhaps there could be a national competition for electric-furnace melt technology?
*Trucking is going electric,so that can be renewable.
*Rail freight is already electric,we can lose the onboard 'range-extender' diesel engine,and provide the catenary line.
*On-site foundation preparation and erection can all be done with electric,renewable.
I'm not seeing insurmountable hurdles.
