I do not discount the environmental impact of conventional car production/disposal, but the battery issue for EVs, mostly about disposal, is a big concern. It's like nuclear energy waste, which remains a danger to both people and the planet. I guess I don't want to add to that. There needs to be a better way of safely disposing/recycling of spent batteries.I see your point that you won't be buying a car soon, but I'll reply anyway for the benefit of others.
Your doubts are quite common so it's an interesting discussion.
On the electricity costs, if does depend on how high we are talking about, if it's 30 cents/kWh for example, EVs will still be far cheaper than a conventional car. It has to be something like 80cents/kWh before it costs per mile a similar amount to gas (very rough estimate) and rarely is anywhere that expensive. After you get an EV, you can sometimes sign up to a special cheap overnight rate and mainly charge the car then, which is even better.
I've actually noticed that people talk a lot about the environmental impact of production of and disposal of electric vehicles, but completely ignore the environmental impact of production of and disposal of conventional vehicles. With EVs, you only have to dig up lithium etc once to produce the car and often in a desert where there isn't as much human or animal life to disturb. With a petrol and diesel car, you have to continually dig up oil throughout the lifetime of the vehicle to keep it going, so the impact is much higher. Therefore, the environmental impacts of EVs can only be an argument for not having a car, and not an argument to stay with a gas car.
Yes, wannabe EV owners may have to upgrade their electrics and put an electric charger in, possibly at a cost of $1,000-$2,000 (a rough guess, but it varies). However, that is not much compared to the overall cost of owning any car for some years. It just feels like a big chunk at the start which is part of the issue, especially for people that don't have savings and can't get (good) credit.
For long trips, a 2 hour trip might be a 2.5 hour trip in an EV, and a 5 hour trip might become a 7 hour trip, but it varies. If EV owners can charge from home they make back that lost time on the occassional longer trip by all the time you save at the gas station. Plus, on the longer trips , you just use those 15-45 minute breaks to catch up on whatsapp messages, the news, or getting something to eat having planned ahead and not looked at all your whatsapp messages and news earlier in the day.
I actually think your post demonstrates the hesitation people have in making a change, even when that change will make people (eventually) better off and happier eventually. Again, not you personally since this isn't the right time for you, but for anyone else.
RE: Solar: I would love to go solar, because I plan to stay in my house (which gets pretty good sunlight) for as long as possible, but again, it's upfront money that is the issue. I just don't have it. One thing I do use a lot is my solar oven. I love that thing.
