How does Jevon's paradox play into the current situation with commodities?

Oil demand holds up in Norway, despite record electric car sales
In September, electric cars reached a record 77.5% share of new car sales in Norway. Yet, surprisingly, oil demand is higher than ten years ago when the first zero-emission cars were sold in the country. (UBS Editorial Team, 08 Dec 2021)

Zubin Al Genubi laments:

It's like my garage storage and my budget, demand grows to meet supply. Also despite efficiency the same energy created is used.

The road-congestion version:

The Fundamental Law of Road Congestion: Evidence from US Cities
Gilles Duranton and Matthew A. Turner
AMERICAN ECONOMIC REVIEW
VOL. 101, NO. 6, OCTOBER 2011

Abstract
We investigate the effect of lane kilometers of roads on vehicle-kilometers traveled (VKT) in US cities. VKT increases proportionately to roadway lane kilometers for interstate highways and probably slightly less rapidly for other types of roads. The sources for this extra VKT are increases in driving by current residents, increases in commercial traffic, and migration. Increasing lane kilometers for one type of road diverts little traffic from other types of road. We find no evidence that the provision of public transportation affects VKT. We conclude that increased provision of roads or public transit is unlikely to relieve congestion.

Stefan Jovanovich comments:

There is no marginal cost of entry into the "system" of free roads. The only way that public transit can begin to compete with highways is for their cost of entry - i.e. the fares - to also be zero. I had one great professor at what was otherwise a mediocre school - what Harvard then called Architectural Sciences - who taught this. I can still remember his lectures and one in particular - when he explained how he had been unable to convince the Indonesian government that the solution to their particular traffic problem was to fix the phone system. It was so unreliable that even in what was still a poor country the streets in Jakarta would be jammed by merchants and others getting in their cars so they could talk to one another in person.

Big Al adds:

You'd think that policy would be a natural, especially for "progressive" regimes, given that public transport fares must skew towards a tax on the bottom deciles.
