That elephant is not in the room yet. It's waiting at the Supercharger station a couple hours out on the highway, and won't be here for a quite some time. While that's changing with the Model 3 and the responses of other auto manufacturers, few people own or can afford a Tesla Model S. The elephant that's currently in the room is gasoline-based mobility. 5400 km in a gasoline-powered vehicle at 20 mpg or 14 liters per 100 km is 756 liters or 167.8 gallons of gasoline, and at 33.7 kWh per gallon, that's 5.655 MWh. The commutes multiply the energy consumption by more than a factor of 5. You shouldn't feel good about turning off an LED bulb and using a lamp instead if you also enjoy driving to work in your pickup truck.
