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.

Yeah right!

There is no such thing s economy of scale and we all don't know that these plants all along have been using regular gasoline to run their generators.

Double huh? I saw my first Mach E in the flesh the other night and I like it. Being in NorCal Tesla’s are everywhere. There’s actually 2 E Trons in my neighborhood.
Looking forward to the Lightning if it fits your needs why not?

Before a new argument over generator fuel gets going…

Isn’t a watt a watt regardless of the energy source that was converted to generate it?

Of course.

Unfortunately the calculated need for electricity is coming from converting the amount of crude burned instead of the EV miles driven.

Yeah, satire is dead in the simplistic world where generators is comparable in scale to yuge generating plant and their management are too dumb not to take advantage of the shift in demand to build the capacities and the distribution grid to deliver it. Wait, Texas and Florida are failing on those and you two maybe right after all.[emoticon]

No calls from CA to conserve in this week's heat wave.

Grid status: Normal

I beleive Texas is having issues this week because of extremely hot weather and lack of wind. Texas also had a influx of 322,000 people last year alone. They have to much capacity tied to wind power. I think if a lot of new homes would utilize solar panels it would go a long ways in the sunbelt to elevate peak energy demand. When I build my new garage I will look at installing a large solar panel system.
