Quick Way to Cool Your Home

 
Fighting global warming may be as easy as painting flat roofs white. According to Secretary of Energy Stephen Chu, a white roof reflects solar heat back into space and could reduce electrical usage for air conditioners by 15 percent. Some states, such as California, are already requiring commercial buildings to have white roofs. This would also reduce the "heat island" effect found in many cities since roofs account for one-quarter of a city's surface area. Seems like a good idea to me. Thoughts?
