Hey I'm all for ending fossil fuels, but how is this possible when we are still mostly driving ICE vehicles that require gas? Simply removing the oil industry when the majority of drivers are still using oil seems impractical, and will just lead to very high gas prices. We should be spending more time developing and testing more alternative fuels and methods before just "shutting it down". Promote more EV's and things like that, for now. Eventually, we can have such low demand that the oil rigs can be shut down in due time without a market crunch.
I don't think we have the convenience of a "smooth transition" We made hard pushes for phasing out oil and the industry and their political puppets block or slow things down to a crawl. Taking it slow as a policy is a great way to make sure nothing happens. Oil companies and auto makers would be pleased as punch if they could even roll back emission standards and green energy incentives.
