And yet you have power companies complaining about solar power because it makes too much power during the wrong times. Bottom line is if there was a large number of EVs on the road then it is the responsibility of the power companies to adapt to deal with a change of society not the consumer. After all, do you think they did nothing in the 50s when modern electrical conveniences became common place in the house? No they had too adjust for the changing demand. And i say this as one who had to update electrical on a turn of the century home that had one 15 amp fuse for all the lights in the home, and one fuse for ALL the plugs, so yeah the was a huge change in the electrical consumption of the house.
And yes if 50 million electric cars were on the road with the same number of super chargers as today it would be tragic. Or perhaps a future where ever parking spot in a parking lot had access to a charger, maybe not super ones but enough that you could charge your car somewhat while shopping, dining, etc.
That would be nice. The problem with energy generation is not generation, its storage. There's no way to store excess power and powerplants have to balance generation output with demand on the fly, generators are constantly starting and stopping as load changes. I worked on an extensive smart grid research team 5 years ago and learned a crap ton. Stuff that is mostly useless except in discussions really. But there is much I dont know.
Power aside, we really need to concern ourselves with the massive destruction to the planet strip mining Li and cobalt.
