I would guess that town code frowns at the idea of residents actually painting their roofs a lighter color to reflect the heat of the sun.
Still this article about using lighter colors for roofing materials and car paint is food for thought.
It goes to show that a simple shift in thinking — backed up by a commitment from various industries and the public — can made a huge difference in our energy consumption.
So … the next time you have to replace your roof (or automobile) — go light on the color. Your checkbook and the environment will be glad you did.
