One school of thought is that future oil demand is set to decline because consumers will have better options. Many in this “peak demand” camp believe that the growth of electric vehicles will soon make oil obsolete.That’s a relatively painless view of the future and is consistent with much of our past experience. Old technologies are frequently replaced by newer, better, and cheaper technologies. I have written previously on why I don’t believe this version of future oil demand will unfold anytime soon. In a nutshell, if you “do the math,” it becomes clear that it will be years before EVs can take a meaningful bite out of oil demand. Meanwhile, some organizations are sounding the alarm that rather than a peak demand scenario, we may soon face a peak supply scenario. Or at the least, the loss of global excess spare capacity. The last time this happened, oil prices rose above $100 a barrel.

In January 2017, Saudi Arabia’s energy minister Khalid A. Al-Falih warned CNBC that he foresaw a risk of oil shortages by 2020:

“I believe if the investment flows that we have seen the last two or three years continue in the next two or three years, we will have a shortage of oil supply by 2020. We know, from what we have seen in the last couple of years, that prices around the current level and below are not attracting enough investment. We know the level of natural decline that existing production is undergoing, and we know that demand is picking up at 1.2 to 1.5 million barrels a year. So between increase in demand and natural decline, we need millions of barrels every year to be brought to the market, which requires massive investment.”
