I wonder if the tribes have enough autonomy to build transmission lines quickly. Just the Navajo Nation can build enough solar/wind and transmission lines within their reservation and probably connect to the grids in Colorado, New Mexico, Utah and Arizona. US is incredibly slow in building transmission lines, takes decades.
And, if they have enough autonomy to import Chinese panels (50% cheaper), a network of these nations can blanket the entire country with renewables.
