Barcelona’s amazing smart lightning idea

The city of Barcelona and Spanish utility Endesa have been installing smart LED lightning systems that automatically switch themselves off when no one is around. This enables the city to cut by 30 percent its electricity consumption.

I really would like this idea to spread across Europe and even the entire world. Indeed, how many plants are used only to light streets unnecessarily? This would drastically cut costs and would go far beyond the Earth Hour

Last but not least, this would also improve the night sky quality drastically. As we have seen previoulsy, darker skies would benefit Nature and astronomers alike.

Here is the video presenting the project. Enjoy !
