Here's what the #'s look like for me, pretending for a minute I don't have solar.
In my last power bill I was charged 16.69¢/kWh. This is after my power utility added in the riders on top of the stated 12¢/kWh amount, plus 4% state tax. In other words, for every extra kWh my EV added to my power bill it cost me 16.69¢/kWh (pretending I didn't have solar providing most of my power). This is higher than the average over the past 12 months, but I'll go with it anyway.
Our EV crossover gets 3.4 miles/kWh with our driving habits and A/C use. It actually gets more miles/kWh than that for local driving (charging at home) because the 3.4 miles/kWh includes interstate driving 80mph (road-side charging, which doesn't add to my power bill). But I'll go with the 3.4 miles/kWh.
We drive 26K miles per year in the EV, with about 22K to 23K of those miles charged at home. I'll go with 22K miles charged at home.
Thus, to charge the EV to drive 22K miles it cost $1,080: which I derived from (22,000 / 3.4) X $0.1669. With gas at $3.30/gallon that $1,080 would buy 327 gallons of gas. Even if a new ICE crossover gets the stated 30mpg, that'd cost $2,420 in gas: (22,000 / 30) X $3.30. And these are with my pessimistic EV numbers (my EV gets more miles/kWh for local driving, my power rate in the past month was higher than the average for the past year) vs optimistic ICE numbers (do ICE crossovers really get 30 mpg?).
Now obviously these are Alabama #'s for power rates and gas. I don't know about rates in other areas. And this doesn't get into things like if you're single (read: need just one car) it's probably unwise to depend solely on an EV. Or if you live in an area with lots of cold weather. Or if you can't charge at home. Or if most of your road trips are in areas with poor charging (which would mean taking your ICE car, which in our case is an old pickup we'd rather not take on long trips unless it involves pickup chores), or if both of your cars are in good shape and it's a bad time to spend money on a car, etc. But if someone meets all the personal parameters above and drives at least 15K miles per year (assuming we one day go back to Trump's good gas costs of year 2019) or at least 12K miles per year for today's stupid Dim gas prices, then an EV is worth looking into.
The poster claimed for $6/month he can drive 1,000 miles in his EV.
