Between the Poles: Energy Efficiency of Fossil Fuel Power Generation
So I guess my analysis goes as follows....
Oil to make the electricity=40% efficient, then 60-73% of that is efficient in the EV so 24-30% efficient in the car
Where the Energy Goes: Electric Cars
Oil into an ICE car=12-30% efficient
Where the Energy Goes: Gasoline Vehicles
Which suggests an inefficient ICE car vs the EV , the EV is 2X more efficient but in an efficient ICE car it's the same.
I feel like I understand a little more....if we compare the inefficient ICE car then the EV looks pretty good at half of the emissions. But if we compare efficient cars of both types it looks like a wash. Unless I'm missing something...which is entirely possible.
What's your take?

It looks the same to me, but that still leaves me with questions. Perhaps a golf cart comparison isn't valid. Fuel for my golf cart costs 1/6 what fuel for my gas cart costs. If the efficiencies are the same then the only savings would come from the cost of fuel for power generation: 1/6 what the same fuel costs me. That might be the case but it really seems like I'm missing something.
