Halogen lightbulbs are to be phased out from this weekend as part of an EU-wide effort to improve energy efficiency and cut carbon emissions. From tomorrow, retailers will no longer be allowed to replace stocks of the lightbulbs, which use considerably more energy than alternatives such as LEDs or compact fluorescent bulbs. They also have a relatively short lifespan of about 2,000 hours, or approximately two years when used for about three hours per day. Halogen bulbs have stayed on the market until now because manufacturers said that LEDs were not yet a viable replacement because of higher upfront costs, particularly for the brighter 60W to 100W-equivalent bulbs. A government study found UK homes have an average of 34 lights, with ten halogen. Stewart Muir of the Energy Saving Trust said: “Halogen bulbs are now quite an old technology. They were first patented for commercial use in 1959, so they’ve been showing their age for a while – mostly by inflating your energy bill.”

There are lots of ways to make your home more energy-efficient, from adding more insulation to buying new appliances. Actions such as these reduce your energy use and save you money on your bills, but does it really make a difference for the climate? Recent reports suggest that it very well could. A recent report from the Natural Resources Defense Council (NRDC) and a group called Energy and Environmental Economics identified residential energy efficiency as the largest source of carbon dioxide (CO2) equivalent emissions from a single intervention. According to the study, it could contribute 550 million metric tons of CO2 equivalent emissions reductions each year by 2050. Many countries already require homebuilders to follow building codes that promote energy efficiency. According to research from Climate Action Tracker, if every country across the globe adopted the highest standards, energy demand would decrease enough that 1,000 coal-fired power plants could close. The study used the average size of coal plants, around 600 megawatts, to determine how many could close.
