As always, @MLiebreich on the money in his latest. "Yergin and co. play several other games. They promote the so-called primary energy fallacy, by which the world’s apparent dependence on fossil fuels is inflated. The real figure is not 80% but 68%, because of the differential inefficiency of fossil fuels compared with clean energy, which is also missed by Lomborg, Smil, US Energy Secretary Chris Wright and others. If you think the difference between 68% and 80% is not that important, think about the difference between clean energy meeting 32% or of 20% of demand – instead of one fifth of energy demand being met by zero-carbon sources, it’s already one third. The transition is considerably more advanced than its detractors would like us to believe."
