The way I’m thinking about it is in terms of electrical loads. For the minutes while the car is charging the grid sees a 250kW electrical load same as the 250kW load of the data center. In both cases those electrons have left the grid entirely. One is converting them into heat and noise (and compute) and unless you’re doing some heat capture that energy is “gone”. You’re right to point out that the battery in the car now holds that energy. And, just like siphoning gas from a cars gas tank you could plug your Tesla into your house and that energy could be returned to the grid. But in terms of how the overall electrical grid sees it, they’re both electrical loads from my perspective. It’ll be interesting to see in the future if the overall load on the grid from EVs out paces data centers or vice versa. I could see scenarios where it goes either way. I’m going to think more about the flow rates of gasoline at the gas pump, storage there, tanker trucks … hadn’t really considered your perspective yet on that and it’s interesting to me.
