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 quarter 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 vastly more amounts of energy in the whole petroleum cycle. The total energy used per vehicle would need to include that power used as well. 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 EVs 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. Feel free to check my math - done on an iPhone...
