Details of the government's long-awaited energy bill has been published and does not include a target to slash emissions from the power sector by 2030.
A decision on setting carbon emissions for 2030 will now be delayed until 2016 - after the general election.
An estimated £110 billion is needed in the next decade to renew the UK's ageing electricity infrastructure, with much set to go into low-carbon power sources such as wind farms to cut emissions and keep the lights on.
It is the Government's long awaited light bulb moment. The Energy Bill published today envisages changes that would reach into our lives.
By 2020 we will be paying nearly £100 a year more for energy. But whether bills will come down again afterwards is still in dispute.
The coalition will announce plans on updating the energy infrastructure of pylons and power stations, and cutting our reliance on carbon.
