Energy Bill to create 'low carbon economy', says Davey

Energy minister Ed Davey has unveiled the government's much-trailed Energy Bill, setting out the roadmap for the UK's switch to "a low-carbon economy".

Energy firms can increase the "green" levy from £3bn to £7.6bn a year by 2020, potentially increasing annual household bills by £100.

However, big, energy-intensive companies could be exempt from the extra costs of the switch to renewable energy, as John Moylan reports.
