One zero emission truck is worth about 40 zero emission cars in terms of grams of CO2e. And diesel trucks cannot go zero emission. So this makes no sense to me.
One EV truck = x amount of batteries. Per the article, 700kWh
One F150 hybrid [1] = y amount of batteries. Per Ford, 1.5 kWh [2]
One EV truck = x/y F150 hybrids, or 500 pickup trucks.
500 hybrids pickups are sacrificed to make one Tesla EV semi.
Now, look up the amount of miles driven by your average delivery guy. This guy probably has the worst fuel situation on the road. Heavy vehicle. Stop and go. Urban.
I'll be nice and assume 15000mi, what the DOE estimates for the average commuter
Subtract fuel consumed by Amazon guy on regular F150 (18mpg) vs hybrid F150 (25 mpg) on 15000 miles. 233 gallons.
Multiply by x/y. 500x233 This is the fuel saved by hybridizing. 116 000 gal
116 000 gallons of fuel. I actually didn't believe this, so i did the math twice.
A YEAR
In a year, on average, a semi goes through just less than 10 000 gallons of fuel. [3]
So the single EV truck costs 11X more fuel than the fleet of 500 delivery vehicles that could been built with its battery pack.
Note, that this analysis is incredibly favorable to the EV semi as it assumes there is no CO2 emission from charging it. The batteries magically recharge. This is grossly untrue. Nor am I considering that truck batteries aren't going to last very long.
[1] F150 is used because it comes in regular, hybrid and EV trim, and is roughly the size category that an amazon or FedEx delivery truck.
