Carbon emissions could be cut by 50% in two decades by switching to LED lighting, recent research suggests.
A report by management consultants McKinsey & Company reveals that the switch could be the most cost-effective way to tackle global warming, using existing technology.
The findings, featured in the New York Times, states that LEDs are more than twice as efficient as compact fluorescent bulbs, currently the standard for greener lighting.
LEDs, unlike compact fluorescents, turn on quickly and, importantly, are compatible with dimmer switches.
Indeed, separate evidence suggests that adding dimmer switches to your home could significantly reduce your carbon footprint.
While fluorescent bulbs contain mercury, which requires special disposal, LED bulbs contain no toxic elements, and last much longer. This means that disposal is much less of an issue.
Colin Humphreys, a researcher at Cambridge University, quoted in the New York Times, described LED lighting as “fit-and-forget lighting that is essentially there for as long as you live”.
While the cost of LED lighting may initially be higher, savings are made in the long term because of LED longevity.
Leading retailers, such as the online store Lights2Go include a range of LED lighting suitable for indoors and outdoors. They also stock dimmer switches suitable for the whole house including bathroom lighting.
