BEVs are like the best consumers imaginable for our grids. Their owners get hourly contracts and perfectly time their charging when the prices are low helping stabilize the grid.
Some even grid companies even support adding cars charging to the ancillary markets further increasing grid reliability - while also paying the BEV owners for their service.
Taking in the supply chain from producing oil, refining it and transporting it the change in electricity consumption is negigible because especially the refining step is quite electricity intensive.
But if no refining happens in a market then something like a 20-30% increase in electricity usage is expected.
Please do tell me how that entails a "collapse"?
Of course not at all engaging with the point about BEVs acting like demand response for a grid. Scheduling their charging to not add more load when the grid is already strained, unless forced to do so due to e.g. being on a roadtrip without possibility of timing the charging and therefore paying a premium for expensive electricity.
All in all I see a lot of hand waving and little substance.
Did you miss the portion where on average the refinement of raw crude to gasoline/diesel is neutral in terms of electricity usage compared to just driving a BEV?
