Traffic lights surely require a lot of juice, especially when you’re talking about big metropolises like New York or London. And while cities are rolling out more energy-efficient LED traffic lights, the end result is still a significant drain on the power grid.
The solution: why not rely on solar power? Batteries can always store energy for the night or cloudy days, and utility electricity can become a last-resort back-up. The problem is that the initiative seems to be taken by so-called second- or third-world countries like Turkey, South Africa, and India. (Image and source: treehugger.com)
