Even in California where we're paying $0.15 - $0.20 per kWh of electricity, electric vehicles save so much gas that they almost pay for themselves.
Only because you're getting ass-raped on gasoline as well. When I topped off the gas tank here in Vegas before driving down to LA last weekend to visit my nieces, I paid $3.04. I pulled over in Baker for a snack. The gas station next to the jerky place wanted somewhere around $4.50! Granted, Baker's never been the cheapest, but gas in Barstow was still around $3.70. I think it was $4.something around LA, and by the time I was running on fumes Sunday morning (driving down to San Diego to make everything worse), I ended up paying right at $4 per gallon ($3.999, if you want to be pedantic) for a full tank in Carlsbad.
Gasoline is sent to Las Vegas from California by pipeline, so how is it we're paying considerably less for the same fuel after it's been pumped through ~300 miles of pipe?
