Accelerating the switch to LED
Lighting accounts for 13% of all electricity usage worldwide. By moving to energy-efficient LED lighting, lighting-related energy consumption could drop to 8% globally by 2030, even while the total number of light points continues to rise. It’s a fast, non-disruptive intervention that can act as a frontrunner for deeper and more complex renovations. Given that two-thirds of professional light points around the world are still conventional, the energy-savings potential of switching to LED lighting is enormous.
LED lighting reduces energy consumption significantly over conventional alternatives—well over 50% in most cases. When connected and properly managed, monitored, and controlled, LED lighting systems can push energy reductions to as much as 80%, producing startling results. In addition to enhancing its efficiency, connecting LED lighting to a network and introducing sensors and controls lays the groundwork for digital smart building and smart city frameworks that bring together multiple functions and applications.
If businesses and cities converted all of their conventional light points to LED or connected LED, global electricity savings could total as much as 1,132 TWh per year, equivalent to the annual electricity consumption of 494 million households. The switch would save a total of €177 billion per year in electricity costs while taking more than 553 million tons of CO2 out of the atmosphere. That’s equivalent to the amount of carbon that 25 billion trees could sequester in a year.
The results can be significant even on the local level. In a mid-size European city of 200,000 inhabitants, for example, switching all conventional lighting to LED could save over 78,000 MWh, over €26 million, and over 18,000 tCO2 per year.
