How much energy do LED streetlights actually save?

LED systems are increasingly being adopted around the world in a variety and increasing number of ways. They are being increasingly used in households and for bigger government infrastructure projects.

For several governments around the world the energy savings have inspired large projects aimed at replacing old inefficient streetlights with modern LED lighting. But how much energy does implementing this kind of technology actually save?

The Climate Group has recently released the findings of a two-and-a-half-year study which examined the use of LEDs in major cities, and how consumers view these lighting systems.

Titled “Lighting the Clean Revolution: The Rise of LED Street Lighting and What it Means for Cities”, the report is aimed at policymakers and city lighting managers who want to further explore the potential of LED technology in urban areas.

Piloting 15 separate schemes in 12 cities across the globe — including New York, London and Kolkata — the company found that in some cases, LED technology accounted for an 85 percent reduction in energy costs.

The LED lighting systems under trial indicated that those with a lifespan range of 50,000 – 100,000 hours provided the best return on investment for lighting urban areas and cutting costs. Furthermore, the rate of failure after providing 6,000 hours of lighting was far lower than traditional lights — at only one percent.

The programme also indicates that citizens of pilot cities prefer LED lighting, citing social and environmental benefits. In Kolkata, London, Sydney and Toronto, between 68 and 90 percent of respondents indicated that they approved of city-wide LED rollouts.

Mark Kenber, CEO, The Climate Group said:

“This report clearly highlights that LEDs are ready to be scaled-up in towns and cities across the globe. We are now calling on Governments to remove policy obstacles and enable a rapid transition to low carbon lighting.”
