I think charging costs really depend on individual situations. We put solar on our home 3 years ago. Initially it had a 7-year payoff period but with rising electricity rates in CA it's down to 4.5, so we are 1.5 years away from "free electricity". Last year, even with charging our Volt November/December our total electricity bill for the year was $61. YMMV.My buddy has a Tesla and says it’s terrible for trips, repair times are terrible and loss of value is equally as bad. He said he would never recommend one. I drove it and it’s nice but it seems like they put the cart before the horse, infrastructure for support in terms of repairs and charging stations just aren’t there. He got the home charger and said his electricity bill tripled.
