Overview: Miners, nuclear scientists, politicians, environmentalists and even the City have all wrestled for control of the national electricity grid and the power that it has brought. The final film in this history of the grid charts how it has been the battleground for conflicts that have changed and shaped Britain. Key players from the miners' strikes reveal why the industrial action of the 70s and 80s had such different impacts on electricity supply. The film also uncovers how Britain lost her lead in the field of nuclear power. Contributors include former conservative cabinet minister Lord Jenkin, author Will Self and veterans of all the different fuels. They examine the cost of our love affair with power and consider the perils of life without it.
