Sir, Although David Cameron’s intention to reduce energy prices is superficially laudable (report, Oct 25), he is simply shifting some of the burden from consumers to taxpayers. This does nothing to put our electricity supply on a more rational foundation. The next step should be the elimination of subsidies for renewable energy generation. If solar farms and wind turbines make economic sense, suppliers will invest in them. Until then, the government should focus on ensuring we have secure, affordable energy.
