Diesel powered generators should provide reliability for those EV chargers when the electric grid gets over loaded... West coast doesn't have the luxury of hooking the EV chargers to natural gas lines to save money as other areas east of the Rockies... Does anyone know how much less emissions would be produced if they used the natural gas infrastructure to power vehicles instead of the multi layered EV system being spinned?... Enormous difference in emissions... The multi layered EV system wouldn't be producing profit at each layer if natural gas vehicles were pursued... So we watch...LJ
