Power grid in 1st world countries unable to sustain the use of EV vehicles nationwide

Yes, assuming everyone charges at the same time, all the time. If they charge enough to cover the miles driven, it's more than enough. Forbes did the math, https://www.forbes.com/sites/jamesmorris/2021/11/13/electricity-grids-can-handle-electric-vehicles-easily--they-just-need-proper-management/?sh=61c2c0f87862

Cali is already saying they expect rolling blackouts

Not this year, https://www.cnbc.com/2022/09/07/california-avoids-widespread-rolling-blackouts-as-heat-strains-grid.html

By using a distributed network of batteries, and asking customers to reduce demand (like charging EVs off peak) they kept the lights on

There's another potential issue coming up this week, high winds may knock down power lines, so the power companies shut off power to prevent forest fires. But that's not so much a supply/demand issue, https://www.bloomberg.com/news/articles/2022-10-21/california-faces-weekend-blackouts-as-utilities-brace-for-gusts-and-fire-danger

Lol....so asking people to not use electricity, maybe they will keep the power on? And then they mandate by a certain year to stop production of gasoline vehicles ..reeeeeal smart

That's right. A smart grid. We used to only have control of the supply side of the grid. We're beginning to have control of the demand side

A responsive grid is less expensive (peaker plants are the most expensive power source) and cleaner (peaker plants are some of the dirtiest sources of energy)

I think some rolling blackouts while production increases is ok in the short term when the alternative is doing absolutely nothing to stop the end of the world

The goverment comisioned studies several years ago and concluded that EVs will result in an additional 10% increase impact in Britain, and they considered the grid capable to sustain that without any problem, not only that, the grid is ongoing sustaining development as we speak and money being invested on it because renewables or not smart grids are beneficial for a number of reasons

and if britain grid can sustain it, I bet my arse that Germany and France aren't any far behind
