About two years ago, I asked a gas station/convenience store owner
what the normal amounts of electricity they used were, and he said
about 350 kWh in summer, and 250 kWh in the winter. (Natural gas
heating). I asked if this was for an entire month, and me said no,
that was the amount used for a single day! He showed his power bill
as proof. I was quite surprised, as my house uses roughly that
amount per month.
Granted, most of the energy was used for beverage and food coolers
(about a dozen) and air conditioning. He estimated that the eight
gasoline and two diesel dispensers and lift pumps was about a
of the total energy use for his station.
If one considers this a typical store/gas station, and it serves
perhaps 2,000 vehicles a day, each vehicle's share of energy is
between 125 and 175 Watt-hours
(0.125 to 0.175 kWh) when they fuel up. This takes into account
their 'use' of powering the store, whether they buy soda and
cigarettes or not.
Obviously, energy used at a gas station is only a small part of the
equation- extraction, transport, and refining of crude oil use
more amounts of energy in the whole petroleum cycle. The total
energy used per vehicle would need to include that power used as
Thought of another way, if the station were to go away (due to
customer attrition) there would be an additional 250 to 350 kWh
available per day for the grid to power plug-in vehicles. At 250
Wh/mi, that would translate to 1,000 to 1,400 miles per day of
electric driving. Or enough miles/power to satisfy about 25 to 35
doing forty-mile (round trip) commutes. The gas station attrition
model would appear to need to eliminate about 2,000 ICE vehicles to
shut down one gas station.

That would be interesting information. I'll take a stab at an
answer, based on this EIA graph:
Overall, it shows that commercial uses about 80% the amount of
residential (this is a visual interpretation). The figure, from
EIA, for residential is 11MwH per year. So, let's say the average
commercial location uses 8.8MwH per year.
Now for the EVs: If the average EV uses 300wH = .3KwH (including
accessories, charging losses, etc.) per mile and the average driver
goes 20000 miles per year, that's 6MwH of charging per year.
So, based on averages and some EV assumptions, the gas station
enough electricy to charge somewhere between 1 and 2 EVs.

Typical right wing ignorance.
What happens when 50% of cars are EV's. Then only 50% of the gas
remain operating. How much ELECTRICITY does a gas station
wild a$$ guess is maybe the same as what it takes to charge 50
add up all the ELECTRIC savings by closing all those gas

distribution system, and turning off HALF of all the electricity

Tonight I'm going to drop by my neighborhood gas station and see
owner will tell me his electric bill and even better, if he will
tell me how
many cars he serves. I DOUBT he will tell me anything about the
cars and the amount of gas since he is in EXTREME competition
