Electricity is crucial to modern life - and in the digital or electric vehicle age, that dependence is going to grow even more. But will we all get the power we need? Chris Bowlby discovers what life is like when power suddenly fails, and how a revolution in the way we generate electricity is posing huge political questions. This could give everyone secure, cheap power - or leave society divided between those with a bright future, and those left increasingly in the dark. Producer: Chris Bowlby Editor: Hugh Levinson.
