Don't believe me.
The numbers are on the web and verifiable. You don't need to think about "miles of transmission"...they can be disregarded because I'm using the price of electricity. The cost due to "miles of transmission" is already factored into the price of electrcity at your home outlet.
So to estimate the cost for fuel (electricity) to operate an electric car you need:
1.cost of electricity
2.amount of it you pull off the grid
3. miles driven
you can calculate cost per mile for the electric car and directly compare with a gasoline car cost per mile as I have previosuly done.
As to the fuel to wheels efficiency comparison its very straight forward. Conversions (efficiencies) needed to charge and run the car are charger 85%, battery efficiency (thermal losses) 85%, motor efficiency 85%.
So ELECTRIC is 85%x85%x85%= 61%
Gasoline engine 25%, transmission 90%.
So GASOLINE is 25%x90%= 22%
61 percent beats 22 percent. This is not Hocus Pocus its just math.
