Without the peak oil scare, we wouldn't be "this" far, I think. Humans need a burning fire under their ass to actually do something.
Promise you this though. Don't think big oil will be down and out. They're going to collect all the cold hard cash they can this next few years. Then, they're going to strangle the commodities needed for renewables. They'll start buying rare earth mining rights, processing plants, manufacturing companies and all. Making sure they make the biggest dollar from the beginning of the energy food chain to the consumer's doorstep. If they can't make money from oil, both God and I as their witness, they'll make their money from lithium and battery manufacturing. To think they're a bunch of mustache twirling dummies is the biggest folly people have.
