Closing the sustainability loop.

Energy Star Compact Fluorescent Lamps (CFLs) consume 75 percent less electricity than incandescent bulbs and last 10 times longer. One CFL can save $30 in energy costs over its lifetime, reduce coal consumption by 200 pounds, and prevent more than 400 pounds of greenhouse gas emissions.

But sustainability is about more than using energy efficient products. It also carries a responsibility to prevent waste of useful materials and to reduce the impact of manufacturing on the environment. For instance, producing an aluminum can from recycled cans consumes 95% less energy than making that same can with raw materials.
