An accelerated deployment of smart energy meters to help tackle climate change is now supported by enterprise minister, John Hutton.
Hutton told the Times he supported a scheme that proposes that smart meters should be installed in all homes within seven years.
Such meters give clearer information to customers about how much energy they are using and how much it is costing them, encouraging them to cut their energy use.

Hutton told the Times, "The energy-efficiency benefit that meters will bring is really necessary if we are to meet our climate change targets."
British Gas also supports an accelerated smart meter roll-out across the UK, which could cost an estimated £6.1bn.
The government is expected to reach an official position on smart metering early next year. Consumers will be concerned that the cost of the meters will be passed on to them through more expensive bills.
