base rate:
Oil has been the largest global primary energy source for ~60 consecutive years with a stable 3-7pp lead over coal and gas. Base rate for retention over 4 years is >90%.
evidence updates:
Iran war/Hormuz crisis creates short-term price shock but doesn't structurally displace oil's lead by 2030. China renewables and OPEC fragmentation provide marginal downward pressure already incorporated in mainstream forecasts. Net modest downward adjustment from pure base rate.
combination method:
Single sub-question, no combination needed.
final:
Oil very likely remains #1 in 2030 per all major energy outlooks. Estimate 82%, accounting for methodology resolution risk and tail uncertainties.
