Want to learn a little bit about how your roof is taxing your wallet (higher energy bills) and the environment (air pollution) -- and how you could change it?
This six minute segment from KQED covers the urban heat island effect (how asphalt roofs, blacktop roads, and parking lots absorb heat, causing higher energy bills and air pollution) and how scientists at Lawrence Berkeley National Lab are working to fight it.
Scientists are developing engineered roofing shingles in a variety of colors (not just the traditional white cool roof) that will keep buildings cooler. The shingles are on the market; they're just not cheap or widely available ... yet.
Listen to the story here.
