The problem with a lot of this is that the more "responsible" you're already living, the less reasonable the next "responsible" thing is to do. Going solar/off grid is only really possible if you live on a lot of land where you're the only resident, which is otherwise generally not recommended. If you live in dense housing, you probably don't have solar, let alone a way to charge an EV. I park my current car 100-500 feet from the nearest outlet that I own. There's essentially no world I could buy an EV and not have to charge it for hours outside of my home.
The efficient future is here, but it's for the rich who did all the garbage NIMBY stuff that made it necessary for everyone else to have to live "efficiently" to make up for their gluttonous use of land/power over the past decades.
By whom? In my case, I am not the only resident, I have a large family on our acreage.
