Over 80% of EV battery charging is done at night.
I don't know their charging habits but their tesla is frequently home during the day so it is possible they do day charging. If not then I assume they are smart enough to use the solar panels for the rest of the house when not charging the tesla.
Tao, if you get your power from the grid, it isn't mostly nukes. It is from electric generators from all over
I am aware but the only major power plant near us is nuke. We have a few solar farms and if you go 60 miles or so a couple NG plants. So while sure some of the coal plants that are 100 miles away contribute as well best guess we see at least 50% nuke with about 5% solar 35% NG and 10% coal. (yes I'm pulling those number out of my ass but if you look at a generation map you will see they aren't totally made up)
Add in the solar panels my neighbors have and their Tesla probably gets 30% solar. 37.5% nuke, 7.5% coal and 25% NG so 32.5% fossil fuel.
My point is not so much that EV are better but you have to consider power source before saying it's only 2/3 as much. Some area's of the country are 100% coal so in those places an EV might be worse than an IC.
Of course most people can't think past the first chess move so it's either EV are great or EV are stupid no additional thought needed.
