Energy Secretary Ed Davey has told the House of Commons that government policy is "designed to reduce consumer bills" as he sets out proposals to reduce demand for electricity - a move which critics suggest will increase households bills.
The long-delayed Energy Bill, formally published today, authorises ministers to almost treble investment in "green" power generation to £7.6 billion, up from £2.35 billion this year.
Davey added in a statement to the House: "The bill is good for Britain's economy and good for consumers."
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.
