This week President Obama's Energy Secretary, Professor Steven Chu, suggested painting roofs white in an effort to slow global warming.
As the article in the Telegraph states, white roofs (and other pale surfaces like concrete) would deflect the sun's rays "rather than allowing it to be absorbed by dark surfaces where it is trapped by greenhouse gases and increases temperature." Ultimately, by painting our roofs white, we would save on energy and air conditioning costs.
What do you think?
Would you paint your roof white if it meant slowing global warming?
