Green Light New Orleans is a grassroots organization that began by swapping incandescent light bulbs for energy-efficient CFL and LED bulbs in the aftermath of Hurricane. In 2015 expanded again to aid in water management by installing rain barrels. Using the same methodology that helped turn the light bulb program from a small grassroots initiative into a huge community movement, Green Light is aiming to provide households throughout New Orleans with 50-gallon rain barrels that are painted by artists. While the rain barrels combat subsidence and flooding, they also make people more mindful of storm water issues and how their individual, yet collective, actions can actually make a tangible difference.
