• I read in the Weekly that coal demand fell in 2016 (23 June). That’s good news. But the language of the industry still dominates the discussion. The author says “energy demand growth globally was weak”. The word “weak” makes it sound as if it were a problem. A better description would have been “Despite our best efforts, energy demand globally continued to grow”.
We know we have to change our industrial and economic model. But it seems that the language we use is one of the big barriers to achieving this. Tim Swann Trelech, Wales
• In her review of Colm Tóibín’s House of Names (23 June), Kate Clanchy refers to Electra as having “a Freudian complex named after her”. In fact it is a neo-Freudian term, having been first used by Carl Jung. What is more interesting is that she then refers to Electra’s brother, Orestes “as the tormented young man who must murder his father”. Orestes did not murder his father, he murdered his mother who had murdered his father. This seems not so much a Freudian slip as a Freudian whopper. Josh Beer Ottawa, Ontario, Canada
