The switch to LEDs at the HMP Elmley prison in Kent could save the Ministry of Justice £115,000

Siemens Mobility replaced incandescent traffic signals with energy efficient LEDs across 161 crossings and junctions throughout the capital for Transport for London

The campaign focuses on raising public awareness about the potential benefits of switching energy suppliers or tariffs and educatingpeople on how to best make homes more energy efficient

The move forms part of a larger scheme to update infrastructure, which will replace 270,000 lights in total, making up 85% of streetlamps across the city

The course claims to be the first in Europe to be lit using LED technology

The project is expected to help the city save around £54m over 20 years

The supermarket’s lighting provider GE Lighting has helped make the switch to greener bulbs

It replaced its old lighting with LEDs at five large warehouses

It upgraded to LED lights at its car parks in Terminal One

The facility enables researchers to grow crops in environments that are similar to the majority of global climate conditions
