E-cars almost always have charge scheduling built-in, to charge when cheapest. Here it is after 8 or 9PM for example.
"E-cars almost always have charge scheduling built-in, to charge when cheapest" if everyone charges when it's cheapest, it will no longer be cheapest. Demand drives cost.
If 80% of US drivers switched to electric vehicles, the total annual electricity consumption would be approximately 1,013,472,000,000 kWh (or about 1.01 trillion kWh). This calculation is based on the assumptions of an average annual mileage of 13,500 miles per vehicle, an average electric consumption of 0.34 kWh per mile, and a total of approximately 276 million vehicles in the US.
As a contrast, today's total output of power in the US is 4 to 4.5 trillion kWh. So capacity needs to increase 1/4 which is not trivial.
Caveat here is we keep the same efficiency in EVs.
Does not seem like a big deal.
A question. Is the extra electricity need to power electric cars less or greater than the amount required by more air conditioning due to global warming.
Key thing. Regulated utilities can't just raise prices to generate a profit. But capital improvements are an asset that you can earn a profit on. So investment is how you can 'grow the business'
Replace the pole pig feeding your house with bigger one? The utility makes a profit off that. If it were me I'd get the utility involved in upgrading residential panels to support heat pumps and car charging.
