The Daily Telegraph reports that the UK’s attempt to ‘decarbonize’ its energy supply is going just swimmingly (my emphasis added):

Ofgem [regulates the UK’s electricity and gas markets] warned there could be energy shortages in the middle of this decade as the UK has failed to build enough new wind farms and nuclear powers stations to replace old fossil fuel plants. It also believes demand for energy may not fall as much as originally expected, as fewer households are insulating their lofts and switching to green appliances than predicted. Ministers are so concerned that factories and large businesses may be asked to switch off their power during energy emergencies in return for compensation from bill-payers…. The supply crunch is the result of Britain forcing old coal and oil plants to switch off in favour of new green wind farms and nuclear plants. Ministers are trying to encourage companies to spend more than £100 billion on new green energy infrastructure by offering huge subsidies. However, the new powers stations will not have arrived in time to avert the possible squeeze in 2015. Ofgem said that the risk of blackouts in that year has trebled from the one-in-12 it estimated in October to just one-in-four, if Britain’s energy demand remains at current levels.
