There will be light
A new energy-saving lightbulb which lasts for 60 years and will retail at £2 has been developed. The bulb is 3 times more efficient than the best performing energy-saving lightbulb today and 12 times more efficient than a conventional tungsten bulb. It can cut lighting bills by 75% and if the new bulb was installed in every home and office it could cut the proportion of UK electricity used for lights from 20% to 5% a year. This is a reduction equivalent to the output of eight power stations.
The bulbs are made using Gallium Nitride (GaN), which is a manmade substance used in LEDs. Manufacturers have already begun work on production prototypes and the first units could be on the shelves within 2 years.
