Lighting
Energy saving lightbulbs use up to 80 per cent less electricity than a standard bulb, but produce the same amount of light. Using less energy means that less carbon dioxide is produced, one of the main causes of climate change.
One energy saving lightbulb could save you on average around £2.50 a year, and around £6 for brighter bulbs or those used for more hours a day. And because it will last around 10 times longer than a standard bulb, it could save you around £40 before it needs replacing. If you switch all your household bulbs you could save around £37 a year and £590 over the lifetime of all of the bulbs.
Energy saving light bulbs use between a fifth and a quarter of the electricity of ordinary bulbs to generate the same amount of light. So where you'd normally use a 60W bulb, you'll only need a 11-14W energy saving recommended equivalent.
