In the USA 1.5% of the vehicles are heavy vehicle trucks but emitt 18% of all vehicle emissions, and in a comparison of the Tesla Semi versus diesel truck it appears as well as zero emissions the Tesla semi saves over 84% of fuel costs or over $40,000 per year of average truck distance of 60,000 miles. The Semi has already gone on sale and available in late 2022. With these savings it can be seen why Tesla has now focused on heavy trucks as they ramp up vehicle production.
In a twitter conversation, Al≡x Gay≡r with @alex_gayer lays out why the Tesla Semi versus diesel truck is over 5 times cheaper for the fuel costs. As Alex says, the jaw-dropping economics of electric trucking are shown up but in that discussion the efficiency is probably understated. The retail price of a semi-truck is often discussed when comparing diesel vs. electric. However the potential disparity becomes far less relevant when the economics of operation are concerned. Electric trucks are more generally discussed at EV Trucks

Other Benefits of Tesla Semi versus Diesel Truck
- A study Switch My Fleet in NZ on a hill road from Christchurch to Akaroa, with a climb of about 500m showed an electric truck would have similar range due to the regenerative braking down the hill that would extend the range.
- Improvement of the driver’s quality of life with smooth, clean acceleration, ample torque, and the ability to keep up with much smaller vehicles in traffic.
- Tesla claim a 2 year payback in energy savings.
