How are they going to provide heat when a sub-zero polar vortex descends on the Midwest?
No coal, no nuke, no natural gas, no oil...
How are you going to retrofit the trucks bringing goods to market? Electric motors? For 75,000lb trucks?
How will enough electricity be generated to charge all of the electric vehicles? Wind power and solar? Hell the solar plants near Vegas are powered by natural gas at night.
