I know I'm an unusual case, but in my case, the electric is effectively "free", so I only pay when I exceed my electric range and have to burn gas, and because I am a telecommuter and work from home, I only exceed my electric range on pleasure trips. My electric is free because I purchased a home with a solar installation already installed on the roof, and it generates more electricity than I can use (and the electric utility barely compensates me for the surplus that I feed into their grid, so I'm confronted with perverse incentives to use more electricity than my usual habits require).
If not for that, I'd have a very different take I'm sure. Electricity is particularly expensive in California (as is gasoline), but also extremely confusing in terms of trying to discover your true average price per KWh. My utility charges something like 15 cents per KWh for the fist X KWh, and then 25 cents for KWh above that. But they are preparing to put everyone on TOU rates that will be very different. And if you have an electric car, they will install a second meter for charging the car at off hours, and bill you a more favorable rate on that meter. They'll even kick in for some of the electrician cost for that work. In my (admittedly unusual case) it makes no sense to get a second meter, but for most other folks (that don't have solar panels that generate more electricity than they consume) this might make sense.
As of March 11 2019, my local Chevron station is charging $3.45/gallon, and the "cheap" place near me is charging $3.17. I imagine pretty much everyone reading this is enjoying more favorable gas prices than we see in this part of the world.
