Pointless and expensive political gesture

Yesterday was the first day since coal-fired power stations came into use in 1882 that Britain has spent without electricity produced from coal. Was that something to celebrate? Not really, given that coal remains the cheapest fuel and that all yesterday’s energy was coming from gas, nuclear, a bit of ‘occasionally availables’ (wind and solar) and imports from France – all at a greater, going up to a significantly greater, cost compared to electricity from coal.
