Lights go down on the roads in bid to save cash
GROUND breaking technology is helping cut street lighting energy costs and save the planet.
Durham County Council is piloting a revolutionary system in Chester-le-Street on a three-mile section of the A167, one of the busiest roads in the North East.
Street lights can be dimmed and monitored for faults using the internet, doing away with the need to send out patrols at night. Depending on traffic flows, lights can be dimmed by 30% between midnight and 5am but lights at key junctions are kept on full power.
The system, called Leafnut, has been designed by West Yorkshire based Harvard Engineering plc and has the potential to save up to £46 in energy costs and 100 kilograms of carbon emissions for each light.
Light levels on the A167 are reduced when traffic volumes are low but areas leading to the road are unchanged.
