In five years time the lights go out

Because we don't have enough generating capacity to meet demand. For three reasons

1 EU environmental compliance (20% renewable and CCS)

2 Old and non serviceable power stations

3 We are running out of fuel

So we will lose

1/3rd of coal power stations by 2015
2/3rd of oil generation capacity by 2020
Closure of all but one nuclear power station by 2022

The only solution in the short term is imported gas. And maybe an Energy Tax, the Climate Change levy to get the carbon price up and stimulate power station investment.
