The largest problem with bringing back manufacturing to the USA is the amount of Electricity available. TVA has the potential of a little surplus....but not enough.
The 2 new chip plants going into Arizona are facing the EXACT same issues. Where they are going to get the juice is beyond me. Texas electricity (had a huge surplus) is sold to California at premium prices because they refuse to generate their own.
And power generation requires water....lots of water for the steam and heat exchangers.
Arkansas, New Mexico, and Colorado could generate more....maybe Oklahoma too.
Dunno....the solar plant in the Nevada desert went bankrupt. (So much for green energy)
In Georgia, there are areas no more subdivisions can be built because there is not enough available power. They need the housing but there is insufficient power available on the grid to power them.
So....
The EPA has been effectively muzzled and restrained. But that still is not enticing power producers to invest.
I have yet to hear of any new generating plants in the works.
