We can be a bit more precise than that. In the US, each 1% shift in Vehicle Miles Travelled will increase electricity demand by 0.25%. This is a BFD, but even a 100% conversion to EVs would only increase demand by 25%, not 100% ("double"). I haven't done calculations for other countries.

- toomuchtodo 9y agoThere's a DoE paper from about 5-7 years ago that shows ~80% of light vehicles could move over to electrification, and if charged at night during off-peak, no additional generation capacity would be required.
- spenrose 9y ago1) The key word there is "capacity." The energy still needs to be generated. 2) Coordinating EV charging with grid dynamics is a hot topic, but getting 100M vehicles to charge largely at night is not on anyone's roadmap for the next decade.
- toomuchtodo 9y agoIt’s on Tesla’s roadmap. They already manage EV aggregate charging in parts of Scandinavia.
- erikpukinskis 9y agoWhat has to be coordinated? People drive to work, park, drive home, plug in, and the car minimizes charging fees. I assume there are already APIs in place to get spot prices.
- erikpukinskis 9y agoRevenue would still go up in that scenario though, no? And costs somewhat.
- toomuchtodo 9y agoCorrect.
