Earlier, Chicago officials confirmed plans to replace 85% of street lights with LED lights in the next four years, making Chicago one of the largest cities in the world to turn street lights into LEDs.
The plan replaces 270,000 high-pressure sodium lamps with more energy-efficient and long-lasting LED lights.
The plan, starting last year, is expected to cost 160 million dollars (about 1 billion yuan). However, it will also generate energy costs for the Chicago Parliament.
Led manufacturers say that LED technology can reduce energy consumption by 60% to 80% and achieve return on investment in two years or less.
The plan also includes a smart grid that can be instructed when the lamp is not working so that residents can no longer report the failure.
Chicago Mayor Rahm Emanuel said: "This project is a win, not only one of the largest lighting modernization projects in the United States, but also reduce the number of residents to call 311 (Note: 311 is the Public Service Center hotline)." ”
"Under this proposed project, we will provide modern, reliable and high-quality lighting that will improve the quality of life in every community in Chicago," he said. ”
Replacing streetlights with LED lights is a global trend, with more and more cities around the world turning to LEDs to cut costs and carbon emissions.
