Madrid Announces Largest
Energy-Efficient Street Lighting Project
New energy-efficient street lighting in Madrid, Spain.
The city of Madrid has announced plans
to renew its entire street lighting system with 225,000 new energy-efficient bulbs, the world’s largest street-lighting upgrade to date. The new lights, which will afford the city a 44-percent reduction in energy costs, will pay for themselves, according to Philips
, the company supplying the new system. In addition to drawing less overall power, the bulbs’ intensity will be controlled from a central command panel, resulting in less wasted energy. Of the 225,000 new lights, 84,000 will be locally manufactured LEDs, and the city is taking measures to ensure the safe recycling of heavy metals found in the old lamps. Similar, though smaller, projects have been undertaken in Argentina, Sweden, and the Netherlands.
