They keep citing fusion as the answer to increased electrical generation BUT the scientists are still unable to run a fusion plant that generates more electricity than the input.
The US has huge areas of empty desert - just perfect for solar power. Might be worth investing in say 100 acres near a big city ?
I gave you that article because there are several different versions of basic order of magnitude calculations based on gallons of gas currently burned, efficiency of gas and electric engines and the electrical distribution system that you don't need a PhD to easily follow. All come out to roughly the same answer, the Excel version is just more accurate because it goes into second order effects like the use of batteries for grid ancillary services and storage. It matches up with my back of the envelope as well.
Quick glance and just a couple of flaws; Assumption that electric is 4x as efficient as gas is a bit of a reach. I'm fairly certain ICE efficiency is lingering around 25% now a days. Electric 80-90 I'd reckon. Also, no transmission losses in the electric grid seem to be accounted for. Might sound like nit picking but it adds up. Surprisingly low number though...I'll have to read up more.
ICE is 25% at ideal throttle settings, which most driving sadly isn't going to be at. Grid losses are a lot less than you might guess, shorthand in the industry is 7-15% generator to consumer. Anyway, rough order of magnitude it's some low double digit percentage increase over today's generation vice a multiple of today's generation, even if you assume all the worst case numbers.
