And people who insist that PV wind turbines are the only acceptable means to generate should be the first people to be switched off at night when there is no wind.
Tesla powerwalls are an interesting development for storing the generated energy. Expensive at present even though Tesla have indicated that they won't overly capitalize on the technology. Rightly or wrongly, Tories cutting the FIT subsidy have murdered this as a domestic innovation for the forseeable future. Commercial might still be a runner though.
