I figured 35% efficiency for combustion engines. 337,000,000 gals x 35%
What percentage did you use for the electrical side of the equation?
I didn’t - I’m electrically challenged.
If a generating station is “1000 mega watt” is that the same as saying “1000 MW per hour” ?
I took a look at the gas vs electric issue from a different angle. This is the worst case scenario. I don't know why I bother to say that because several people here want to act like it is the norm rather than a rare exception. Anyway, if I were to use a Honda EU 7000 to charge my Tesla Model Y it would get 25 mpg. My wife, who is a bit of a lead foot, only got about 20mpg from her much smaller Kia Optima. Even under this worst case scenario driving the Tesla reduces her carbon output by 20%.
The reality here is that most of our power comes from hydro and nuclear with a fair amount of solar mixed in. TVA does still have some coal plants but they are being phased out so our real carbon output is reduced much more than 80%.
This calculation is based on the EU 7000 generator producing rated output of 5500 watts for 6 hours while using one 5.1gal tank of fuel vs the Tesla needing 250 watt/hrs per mile.
