But, hey, on the plus side, while you’re sitting in the dark, you can revel in your planet-saving sacrifice. Telegraph:

Britain faces an increasing risk of power blackouts and higher electricity bills in the next four years, power regulator Ofgem has warned in a report.
An “unprecedented combination” of the eurozone crisis, tough EU environmental laws and the closure of ageing coal and oil-fired power stations, has increased “the risk to consumers’ energy supplies”, Ofgem said in its annual Electricity Capacity Assessment on Friday.
The regulator, which first highlighted the problems in its Project Discovery report in 2009, said: “Today’s report shows that these problems have not gone away.”
It said spare generation capacity – the margin the power system has to respond to increases in demand – could fall to 4pc by 2015/2016 from 14pc today and tightening electricity supplies “could lead to higher bills”.
“Coal fired-generation is likely to close earlier than expected under EU environmental legislation and the risk of a shortfall in electricity is highest in 2015/16,” the regulator said.
The threat of electricity shortages reinforced the need for energy reforms to encourage investment, according to the report.
