We all know how cool science is. But look how easy and logical it can be, too! Why does it take putting a Nobel Laureate into a position of power to bring ideas like this to the forefront of the discussion?
LONDON(AFP) (AFP) – US Energy Secretary Steven Chu said Tuesday the Obama administration wanted to paint roofs an energy-reflecting white, as he took part in a climate change symposium in London.
The Nobel laureate in physics called for a "new revolution" in energy generation to cut greenhouse gas emissions.
But he warned there was no silver bullet for tackling climate change, and said a range of measures should be introduced, including painting flat roofs white.
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.
And painting cars in cool or light colours could deliver considerable savings on energy use for air conditioning units, he said.
Speaking at the start of a symposium on climate change hosted by the Prince of Wales and attended by more than 20 Nobel laureates, Chu said fresh thinking was required to cut the amount of carbon created by power generation.
He said: "The industrial revolution was a revolution in the use of energy. It offloaded from human and animal power into using fossil fuels.
"We have to go to a different new revolution that can severely decrease the amount of carbon emissions in the generation of energy."

Save the world!
Fascinating stuff. Thanks for posting!
Iiiiiiiinnteresting!
What an incredible idea! I hope they have taken into consideration the energy cost of producing all of this paint, especially the 'special' paint they mentioned.
I absoluetly agree, the climate issue needs to be attacked from a variety of angles. I sure like the idea of green roofs better, but painting them white is alt easier and cost efficient for those who cannot plant greens on their roof!
This is very cool! I love this.
Would it make it harder for car air conditioners to offset the heat radiating from the road and cool the interior?

Cool! (er, so to speak.)
Bumping you.
