Do they still just burn off that gas?

> Oil is cooked. BYD is […] By "vehicles" do you mean "cars"? Because airplanes are also a type of vehicles. So are container ships. Neither of which are very practicable with pure electric AFAICT, and are integral to modern life. (Though more marine hybrid could be practical.) I think there should be more of a push for BEV/hybrid cars (and transport trucks), and think more home electrification would be good (though…
> Neither of which are very practicable with pure electric Yet. The surge in electric cars is a driving force for new tech - higher energy density batteries, faster charge rates, longer life, etc etc. For shipping it’s only a matter of when. Planes are harder, but just today electric choppers started flying in NYC. It’s coming.
Remember that oil/petroleum is used in things like plastics, fertilizer, lubrication, non-natural-rubber seals/gaskets, LNG extraction has helium extraction has a by-product.
Reduction in oil-for-transportation can be reduced (thus reducing climate change effects), with oil-for-other-things still being a thing.

Looking at the chart in the article I was kind of surprised at how small wind and solar are globally and that coal is still ~25%.
I believe that it's a physical plant thing. We have spent over a hundred years building hydrocarbon-based energy infrastructure. Much of that is still out there. Wind and solar have made a ton of progress in the last 15 years or so, but it's only really become substantially better financially in the last 5 or so years maybe. It's still going to take decades to actually replace most of that stuff, just as a matter of…
I remember driving by a refinery years ago and it had two or three towers with big flames that were just burning off waste gas. This seemed wasteful to me. If it can burn, then it seems like it could be used for something productive. Do they still just burn off that gas?

You'd need to either liquify that gas or collect it to a pipeline in order to make it useful. I remember reading that modern refineries make use of the gases instead of flaring them though I'm not sure how.

Often methane as a by-product of oil production is flared, because the amount is small enough that it's not worth setting up processing plants and supply chains for. Other times, the fluid is heavily contaminated by e.g. sulfur compounds, and would be costly to purify. Still other times the production of the fluid is unreliable or intermittent, and cannot sustain a continuous production process.
Although, flare gas recovery systems exist nowadays to make use of these waste gases, commonly for local power production for the refinery itself.
