That will eliminate range anxiety once charging stations are as common as gas stations.https://www.ft.com/…/6224f235-568c-4e2f-8247…One gallon of gasoline is 33.7 Kilowatt-hours. Tesla S claims 400 miles with an 85 kWh battery. Toyota’s 700 miles is about 150 kWh. The very best supercharger gives 150 Kw to charge the Toyota in an hour.A Bucee’s gas pump delivers 20 gallons in 5 minutes. 4 GPM is 134 kWh per minute, 60 times as much energy per minute as the most wonderful charger.Buckee’s needs 150 pumps to meet demand. Round down to 100 kWh per minute to allow time between cars. 150 pumps put out 15,000 kWh per minute.The average home uses 900 kWh PER MONTH; Buckee’s supplies 15,000 kWh per minute. 43,200 minutes in a 30-day month; Buckee’s can supply 648,000,000 kWh per month, enough for 720,000 homes.The US Geological Survey tells ushttps://www.usgs.gov/…/how-many-homes-can-average-wind…At a 42% capacity factor (i.e., the average among recently built wind turbines in the United States, per the 2021 edition of the U.S. Department of Energy’s Land-Based Wind Market Report), that average turbine would generate over 843,000 kWh per month-enough for more than 940 average U.S. homes.It would take 765 wind turbines to equal the power of ONE Buckee’s gas station.Are we there yet?USGS.GOVHow many homes can an average wind turbine power? | U.S. Geological Survey

An electric motor is far more efficient converting 85% of the energy into motion. The rest of the energy that your car consumes becomes heat, which we normally just throw away. Based on that, 20 gallons of gas is equivalent to 168.5kWh. At an average of 20mpg, that vehicle would go 400 miles, and consume 674kWh. Now let’s be fair and compare the Tesla Model S with an 85kWh battery to a vehicle getting 28mpg. The Tesla Model S with an 85kWh battery has a claimed range of 310 miles. It consumes 85kWh of power doing that. The car getting 28mpg will consume 11 gallons of gas and consume 370.7kWh to achieve that. A Buc-ees station pumps a lot of petroleum product that mostly generates heat. If there wasn’t a really strong argument to move to EVs, you now have one. An EV is 4.36 times more efficient than your above average gasoline vehicle. Notice that I said EV and not BEV. That is because I feel that fuel cells (hydrogen and air in, water and electricity out and can be refueled in the same time as a petroleum powered vehicle) are the future and not huge batteries. But conservatives don’t care about efficiency. They like to be very wasteful when it comes to finite natural resources.
