An energy crisis is gripping the world, with potentially grave consequences

The economic recovery from the pandemic recession lies behind the crisis, coming after a year of retrenchment in coal, oil and gas extraction. Other factors include an unusually cold winter in Europe that drained reserves, a series of hurricanes that forced shutdowns of Gulf oil refineries, a turn for the worse in relations between China and Australia that led Beijing to stop importing coal from Down Under, and a protracted calm spell over the North Sea that has sharply curtailed the output of electricity-generating wind turbines.
