Mar 16, 2017: Only 10% of USA’s streetlights have been converted from the traditional sodium lights to LED lights in the past few years, despite the fact that LED lights can save up to 50% more energy than the sodium lights. Converting all streetlights to LED will also reduce coal consumption drastically.
The District of Columbia has 71,000 streetlights, and changing these to LED lamps will reduce 14,000 of fuel used currently. Washington’s LED transition will be smarter as it will have remote control system to dim or increase the intensity of lights according to the requirements.
City of San Diego is also becoming smartest. In partnership with Current, powered by GE City of San Diego announced a $30 million investment to implement the world’s largest smart city IoT sensor platform. San Diego will upgrade 14,000 light fixtures to LED luminaires, which is expected to save San Diego an estimated $2.4 million per year in energy costs.
The Department of Energy (DoE) estimates that if the whole country converts to LED lights from sodium lights over the next two decades, it could save up to $120 billion over that period.
Cities across Asia and Europe are already switching to LED lighting to save energy as well as maintenance costs. The Central Planning Agency of China is also discussing its LED conversion program for the whole country.
Transforming its street lighting into LED lighting and connected digital infrastructure, San Diego will collect real-time sensor data across the city that can be used to develop applications that benefit the community.
