If you buy an EV, is the electricity to recharge it free? how is that electricity generated? how long do the batteries last, how much is a replacement. and how do we dispose of the toxic old batteries? How much to install a charging station in your garage and how much will your power bill increase if you recharge the EV each night?
It makes no economic sense, it makes no environmental sense.
Tesla had a program where you could use their superchargers for free for a couple of years. Not now relevant.
As a rule of thumb, charging a modern EV (at least 220 miles of range) from 10% to 90% costs about five bucks if you do it at home, ten if you use a public charger. 90% of charging is done at home. That five bucks compares to $25-30 for an equivalent amount of gas at a gas station. The EPA provides Miles-per-Gallon-Equivalent for every EV sold in America, and it generally runs from 90 to 110. From a cost-to-operate standpoint it ABSOLUTELY makes sense to buy an EV. There is no radiator, no transmission or differential(s). For Tesla's, which offer one-pedal driving, your brakes will last "forever."
Cheap EV's are available. The Chevy Bolt EUV has over 200 miles of range, performs pretty well, and can easily be had for $28k. Within 18 months, Tesla will have a similar car to market. Used Tesla's are very reasonable. And don't forget, the performance of even the most basic Model 3 is comparable to that of a 340 BMW (in-line 6) - no fooling.
How it is generated varies from one geographic area to another, but regardless, your carbon footprint is much, much smaller with an EV over the life of the car.
Battery life is much better than one would suppose. Tesla guarantees them for 8 years, but they have been using Tesla Model S's as taxi's in Europe (e.g., Amsterdam) since the mid-teens, and they are experiencing 800k KILOMETERS as expected useful life - about 500k miles. The thing is, HOW YOU CHARGE makes a big difference in how long the battery will last, and there is not enough history yet to state exactly what is best. Most knowledgeable people are saying, keep it between 10% and 60%. Don't charge it any more than that unless you have to (trips). For your purposes, they will last "forever." Abuse will shorten that. Charging it every night to 100% is the worst practice.
When you (or your heirs) replace the battery, the cost of a new one will include disposal of the old one. At the present time, this can run to five figures, but as the saying goes, "help is on the way." Right now, none of the OEM's is interested in FIXING depleted batteries, but these batteries are made up of hundreds of cells that don't wear out at the same time. Businesses are cropping up now that will test and replace individual cells, at a fraction of the cost of a new battery pack. They will only last 3-4 years, but it will still probably be the best way to go. If you buy an EV today, by the time that battery needs replacement, these shops will be as ubiquitous as Tire America's, so, "not to worry."
How much you pay to install a 220 line in your garage is up to your electrician. Less than a thousand bucks, if he is honest.
Most of the criticisms of EV's is based on either ignorance, or an insistence on using them in a way that makes no sense. If you do a lot of high-mileage highway trips, then an EV will be a pain in the ass. If you want to tow your boat or trailer on a cross-country trip, it makes no sense. In fact, highway driving at 75mph is the LEAST EFFICIENT use of an EV. They are most efficient and most "happy" in routine driving around town.
My wife has a Beemer 3-series that is now 7 years old. Because we also have an SUV, we have never taken the Beemer on an extended trip. There has not been one time in the seven years we have owned it that we would have had to use a public charger if it were an EV. I took her to drive a Model 3 and she loved it, but she can't get her head around the fact that the COULD BE A TIME when she is running low on charge and there is no nearby supercharger. So she is not a convert.
But she's wrong.
