The Daily Telegraph - March 2, 2011: 'Era of Constant Electricity at Home is Ending, says UK power chief'
Excerpt: 'The days of permanently available electricity may be coming to an end, the head of the power network said yesterday. Families would have to get used to only using power when it was available, rather than constantly, said Steve Holliday, chief executive of National Grid. Mr Holliday was challenged over how the country would "keep the lights on" when it relied more on wind turbines as supplies of gas dwindled. Electricity provided by wind farms will increase six-fold by 2020 but critics complain they only generate on windy days.
"We are going to change our own behaviour and consume it when it is available and available cheaply."
