The coalition Government is absolutely determined to help cut energy bills for consumers, reduce costs for businesses and bring down our emissions.
We need to make our energy supply fit for the 21st century, and in a world of rising gas prices we must power our homes and businesses in a much more efficient way.
If you look at all our energy policies together with energy efficiency for example and our reforms to tariffs, we believe that people's bills will be lower in 2020 than they otherwise would have been because of the way we're helping people save energy.
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.
