80% of electricity is from fossil fuels. See the wiki link below.
Using 100w as a comparison:
Average fossil fuel power station efficiency 51% = 51W
Transmission loss 6% = 48W. eia.gov
Electric car efficiency 60% = 29W www.fueleconomy.gov...

Percentage fossil fuel for generation 80% = 36W. en.m.wikipedia.org...

This gives the electric car a total fossil fuel efficiency of 36%. The average US gasoline car is about 20% efficient according to one of the links
above, so it appears that electric cars are better. I'm pretty sure this figure is for older cars as most modern gasoline cars are 25 to 30%
efficient. Modern diesel engines are around 50% efficient, which is much better than electric for fossil fuel efficiency.

I accidentally used european average power generation efficency above. US power generation is below 37%
