Update, keeping transparency.Full transparency: I work for an automaker, and work on EV projects on a very regular basis.
Anyway, we've done studies about this at work. Realistically, it's expected that if every car were to be an EV, there would be a 25% increase in cost per KWH.
At my house, I spend about $170/mo on electrical - $15 of which is to charge my car (FPL gives a good breakdown on their website).
25% higher cost would be $212.50, which means $18.75 to charge my car. The amount spent to charge my car is irrelevant, but I wanted to add it - but this is what's relevant.
That's an increase of $42.50. In my case, with the amount of driving I do, I'd spend that much on gas in a week. So even with an increase in KWH, I still come out ahead financially. I have a feeling most people would as well.
Not just Teslas. Chevys, Fords, Toyotas, Nissan, etc.
Just like they're going to pay those same rates if someone else decides to have a ridiculous christmas light show in their house, or a crypto mining operation in their basement.
This past month, I drove about 800 miles. Total charging at home was $22.08.
