Comment It's a "scenario" added under pressure (Score 2) 70
If you read around a few more articles on this, the new "scenario" assuming no changed regulations or programs anywhere, was added under "pressure". The IEA has some independence, and came up with the peak-before-2030 scenarios a few years ago.
OPEC+ reacted in horror and condemnation, of course, - how dare they effectively call it a sunset industry that will shrink through the 2030s - and set up their own predictions group that came up with a scenario like this one. IEA, (which isn't entirely independent, it's funded by governments, some of them petrostates, and takes funding straight from oil companies themselves) has been under pressure to add the OPEC+ "happy days" scenario to their own suite of scenarios.
The scenarios all have assumptions, and differ because of the assumptions. You can believe these are reasonable assumptions, and the earlier ones wildly optimistic. But a fifth of the cars sold last year were electric, and a quarter of the cars sold this year. The cars are getting better, the underlying battery technologies are improving visibly every year.
Bottom line, this new scenario is heavily influenced by those who would profit from it, and not likely.
