You only have to change every car, truck, tractor, water heater, clothes dryer, lawn mower, leaf blower, stove top, etc to be electric instead of using natural gas (ie electrfy everything), which likely requires all the changes that the parent mentioned. Also, not everyone has enough land to install enough PV to power their entire homes + transportation, so a lot of this is going to have to come from the grid, which requires changes in transmission which are being actively blocked by the current administration (see Grain Belt Express).
