This article began with a simple question - when will we run out of oil to drill? It’s likely that you must have come across the answer that puts the date around 2050, which is derived by dividing the proven reserves we have by the annual consumption. Another answer considers the game of demand and supply. Oil will progressively get expensive as we run out of it, in the face of which, the alternatives will become much cheaper. That is true, but it still carries an unspoken assumption that we are, in fact, running out of oil pretty quickly.
