I was thinking about the cost per KWh and per mile between gasoline and BEVs. Gasoline has between 32 and 34 KWh per gallon, which makes it one of the densest energy fuels there is. The EPA uses 33.7 KWh per gallon for MPG equivalent calculations, so I used that in my calculations.
In energy cost per KWh, gasoline is currently cheaper than electricity, even here in Washington State where it's only $0.08/KWh. Because electric vehicles are so much more efficient than ICE, the cost per mile for the least efficient EV at $0.16/KWh is cheaper per mile than even a 50 MPG gasoline car at $2.00 a gallon.
In places where the cost of electricity is much higher like Hawaii, EVs aren't as economical when gasoline is cheap. Of course if you can put in solar in a place where it's expensive and your only cost of electricity is the original expense for the system.
Anyway, I thought some people might find the chart interesting.
