Keith Anderson, the Chief Corporate Officer for Scottish Power, told ITV News that the targets set in today's Energy Bill for a 40% electricity reduction by 2020 were "achievable".
"What's been announced today really sets the framework to allow the industry to come forward with the investment the country needs to deliver a low-carbon future for the UK.
"Those targets are very ambitious but certainly achievable."
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.
