Can white roofs save the world?

Probably not, but check out the cool info (pun intended) at White Roof Alliance.  The simple explanation is this:  much of the worlds industrial (and personal) roofing is black as are our roadways.  Black surfaces trap heat, warm up, and create heat islands.  And it's not only black roofs!  So the idea is to change the color of our rooftops and road surfaces and thereby cool things down.  Of course they explain it much better than I do, along with the science, but it makes a lot of sense me thinks.

According to the site permanently changing the worlds rooftops would have the same effect as cutting out a full year of man made CO2 (in decreased cooling and heating costs).  Cool.

Check it out.

Color plays a role in heat absorption. Dark colors absorb heat. Light colors reflect it.

We personally think that black roof could help trap the solar energy and this energy could be utilised to to do daily activities. To know more about us read our blog http://zeduniverse.wordpress.com

Thanks for this insights,very interesting because I can try this option to help decrease the cooling and heating costs.

There are facts that also consider dark color roof can absorb heat. Imagine how it can ruin you if you feel so much heat in you environment even inside the house.

Colors can really warm up and cool down the temperature. It has a big effect on the environment. I agree with the white roofs.

This is a great idea.A white roof or road actually reflect the sun's rays back into space, keeping the atmosphere cooler and also keeps buildings cooler, reducing the amount of energy required for air conditioning.This effort will surely reduce global warming.
