The Do the Math blog is interesting because his core assumption is that growth in energy consumption must keep up with economic growth, and therefore economic growth will run into the physical limits of energy consumption. As the Vox article shows, this is an erroneous assumption (you even see a bit of leveling off in the graph he posts). I don't know what it is, but there seems to be a whole genre of physicists jumping into a field their unfamiliar with and trying to crunch numbers to prove the experts wrong without ever bothering to learn the fundamentals of the new field.
