How do you know he doesn't live in an area where the electricity comes from a
nuclear power plant or a hydroelectric dam?

A large portion of the energy on the grid is still generated by fossil fuels and will continue to be almost indefinitely.

Any electricity he uses for his plugin cars is electricity unavailable for others to use. The utility companies must burn fossil fuels to make up for that.

His plugin cars are not carbon free. There is embedded carbon in their construction and maintenance, and in the power plants/windmills that power them, and in the roads and other infrastructure that they use.

The money he uses to buy the plugin cars came from an economy that is still dependent on fossil fuels, and if one has enough money to afford a plugin car, and to pay some premium for "green" electricity, then that additional income represents unnecessary carbon emissions that occurred elsewhere.

Using a plugin car as atonement for flying around in jets is a bit like a dieter adding a low-cal salad to her high-cal meal and still expecting to lose weight.
