The peak of heat in Abadan

This is one of the easiest ways to start making a difference. CFL and LED light bulbs cost a little more than traditional incandescent light bulbs, but they use 75% less energy and last much longer, so the extra cost is definitely worth it! CFL and LED light bulbs are easy to find—you can buy them at your local hardware, grocery, and discount stores.

• Changing 20 million light bulbs to CFLs would save $118 million in energy costs per year.
