The petrochemical industry is huge we've yet to find alternatives for it. Half the stuff around you was made with something derived from oil, and you can't replace that with wind or sunlight in the foreseeable future.

there are pathways to produce synthetic oil from coal or using carbon capture if you have cheap energy. I hope they will catch up if fossil oil prices skyrocket.

We should also note that wind turbines require huge amounts of petroleum derivatives to operate.
