 Compact florescent bulbs (CFLs) are those swirley little guys
that look like soft-serve ice cream cones. Actually, they come
in a myriad of different shapes, sizes, and colors of light.
Economically speaking, they’re a great deal, too. CFLs cost a
bit more than an incandescent, but use about a quarter as much
energy and last many times longer (usually around 10,000
hours). It is estimated that a CFL pays for its higher price
after about 500 hours of use. After that, it’s money in your
pocket.
 How
much CO2 your lifestyle creates is called your "carbon
footprint." Home energy use, cars, and airplanes are how most
of us produce carbon. Is your footprint average? Answer a
