Chicago is set to become one of the largest cities in the world to switch its street lighting infrastructure to LEDs, after officials confirmed plans to replace 85 per cent of its street lights with energy-saving alternatives over the next four years. The plan will see 270,000 high pressure sodium lights, which give a distinctive orange glow, switched to significantly more energy efficient and longer lasting LED lights. The scheme, which began last year, is estimated to cost $160m. However, it is also slated to deliver major energy costs to Chicago City Council. Manufacturers of LEDs typically claim the technology can curb energy use by between 60 and 80 per cent, delivering returns on investment in two years or less.
