US wants to paint the world white to save energy
Talk about every little bit helps! We’ve known for years that white reflects the light back out, but it might just take creative thinking like this to help us turn this thing around. I wonder if this would make my roof shingles last longer :)
“Making roads and roofs a paler colour could have the equivalent effect of taking every car in the world off the road for 11 years, Chu said.
It was a geo-engineering scheme that was “completely benign” and would keep buildings cooler and reduce energy use from air conditioning, as well as reflecting sunlight back away from the Earth.
For people who found white hard on the eye, scientists had also developed “cool colours” which looked to the human eye like normal ones, but reflect heat like pale colours even if they are darker shades.”
