I'm with Dog on the 1 mbpd threshold. This was thr number we were using nominally at the beginning of the thread years ago. At the time, consumption had been growing around 1.6mbpd per year, but as we looked out to the mid-2020s, there were other non-EV reasons why oil demand growth would soften. For a clear example, power generation from oil has been declining a couple percent per year since about 2015. No doubt, solar and batteries have enabled remote and small grid areas like the Hawaiian Islands to replace diesel generation. Additionally, fuel efficiency standards do soften demand growth from new cars. So a 1.6 mbpd threshold for EVs to tip the balance from demand growth to demand decline is way too high at this point. Is 1mbpd still too high? Maybe, but it's okay to be a little conservative.1m bpd/year is the underlying trend. EV sales last year were enough to convert ~160k bpd of that demand growth from oil to electricity. So without COVID & War oil demand would have grown 840k bpd instead of 1m.
I would point out one basic consideration. The threshold that EVs must overcome to halt demand growth ought to depend on the assumptions one is making about EV displacement. If you think you need 40M EV to displace 1 mbpd because new ICE vehicles are substantially more fuel efficient, then you should accept a lower hurdle for EVs than if you assumed 30M EV displacement. At one end of thr spectrum, one could argue that new EVs are replacing the oldest vehicles falling into disuse and that new ICE are also replacing these dirtiest vehicles while adding to the total fleet of ICE. Naturally, some would react that this skewing the analysis to favor EVs. Fair enough, establishment analysts generally skew it to the opposite extreme where they give maximal credit to new ICE for replacing dirty old ICE, leaving EVs to only get credit for displacing only the new ICE vehicles. So fine, analysts can skew their displacement metrics one way or the other, but if the results are to have any objective reality, the analyst should factor that into the threshold. If you want to give ICE maximal credit for efficiency gains, then you need to subtract those efficiency gains from your EV hurdle.
The objective demand peak does not depend on the clever assumptions of analyst. The real demand peak depends on the collective impact on ICE fuel efficiency and how few new ICE are hitting the road. In recent years, new ICE sales have declined faster than EVs have entered the market. If this persists, it can also hasten the demand peak.
Perhaps the better question is, how many new ICE (and hybrid) vehicles must be sold each year to sustain demand for motor fuels? The more efficient new ICE becomes, the greater the number of annual ICE sales must be to sustain motor fuel demand.
