A compact gas car with reasonable efficiency gets 35mpg average. A gallon of gas contains 36.6kwh, and the car would use 2 gallons for the 71 miles. Thats a gas use of 73.1 kw + 31 kwh of the house = 104.1 kw hours of energy use, a 335% increase from the energy used to power your home, and a 76% increase in energy use from the combined energy of driving an electric car and powering a house!
That 35mpg car is also going to use 15kwh of energy just to produce that gasoline! and if someone is driving 71 miles per day then they are driving over 25,900 miles per year, average person drives around 12,500 to 15,000 miles per year so someone is stretching their figures here just to make EV's look bad.

A lot of people who buy EV's seem to also ad solar at some point or cut back their electrical use in other ways, I noticed my electric bill go up by about $10 per month with my EV, then I switched to a gas water heater and my whole utility bill it went down, my parents bought an electric car then installed more solar panels and are selling back the surplus, of course neither of us are rich so we bought some of those lower cost EV's that were not picked on by that writer.
