Back when oil prices were high, people were talking a lot about peak oil supply — the possibility that we’d run out of new sources of crude oil eventually. But now people are talking about peak oil demand — the possibility that we’ll just stop using the stuff as we come up with better options.
Most recently, analysts from Bank of America and Merrill Lynch have predicted that oil consumption will peak by 2030, as electric vehicles become dominant. The (simplified) argument: Right now, batteries make electric vehicles relatively expensive. As battery prices fall, EVs will turn into a bargain and people will start buying them en masse. If 40 percent of new car sales are EVs by 2030, that would be enough to send our oil habit into decline.
