LONDON, January 19 /PRNewswire/ -- Saturday 19th January 2008 is The Great British Light Switch. In just 24 hours over two million people will receive a twin-pack of energy-saving lights free from Southern Electric.

These lights will potentially cut total CO2 emissions by over 350,000 tonnes and save Britons up to GBP20.25million per year on energy bills. Changing all the lights in the average home means households could save up to GBP600 over the bulbs' lifetime.

"The Great British Light Switch campaign is a moment in time when people can act together and make a real difference to cutting carbon emissions," commented Nic Frances, CEO, Cool nrg.

"We hope this giveaway encourages as many people as possible to act now and install energy-saving lights; but also to think about next steps they could take to save energy."

Energy-saving lights use one fifth of the electricity of an old-fashioned incandescent light bulb to produce the same amount of light.

Of the millions of lights in our homes it was estimated that, at the beginning of 2007, only 10 percent of those that could be switched to energy-saving lights have been.

According to the Energy Saving Trust, changing all the lights in people's homes would cut Britain's total CO2 emissions by 3.86million tonnes per year and save Britons GBP1.1billion on their energy bills. The electrical saving is equivalent to the output of almost four 700MW power stations.
