For sure, fossil fuels will still be around for a while. But renewable sources are absolutely going to replace existing fossil-fuel consumption. The economics of it make it an inevitability. Aside from a few niche applications (industrial heating perhaps), there's nothing better about fossil fuels. They've just been the best we had for a long time. Some of this will be sooner (because you decide to buy an EV next month), and some later (because a coal plant gets decommissioned 10 years from now), but the writing is on the wall.

If only HN had a remind-me bot, I'd like to set a notice: oil demand will plateau within 5 years.
