Every year the American public wastes Billions of dollars on inefficient lighting. A simple switch to CFL (Compact Fluorescent Lighting) would save Billions of dollars and eliminate Millions of Tons of CO2 each year. The solution is really as easy as screwing in a light bulb. Here’s how you can get started and what you need to look for.
What is a CFL?
A CFL, or compact fluorescent light, is a significantly more efficient light source than a conventional incandescent light. That means less energy is required for the same brightness (lumens). In general, CFL bulbs use about 75% less energy. With proper care (see below), they should also last about 10 times as long as traditional incandescent light bulbs.
Where should CFL bulbs be used?
CFL bulbs can be used anywhere traditional incandescent light bulbs are used. They can be used throughout the household as well as outdoors. Depending on location, special care may be needed (see below).
How much money do CFL bulbs save?
Generally a CFL bulb will save about $30 to $60 a year compared to using equivalent conventional incandescent bulbs. Several factors determine the total savings. Go here to calculate what CFL bulbs would save you.
What’s the environmental benefit?
Using one CFL bulb prevents the emission of about 800lbs over the life of the bulb. These bulbs use less energy, so they require less energy generation. That savings is good for both your check book as well as the environment.

Energystar.gov provides excellent information on how to maximize the life of CFL bulbs.
Do the twist.
Screw in your CFL by holding the ballast(the white plastic part), NOT the glass tubing.
Don’t flip too fast.
You’ll maximize the lifetime savings and effectiveness of your CFLs by keeping them on for 15 minutes or more at a time.
Give them air.
CFL bulbs are sensitive to extreme temperatures, so place your CFL bulbs in open fixtures indoors. Using them in enclosed fixtures indoors can create a hot environment that reduces the lifetime of your bulbs. Note that covered reflectors are best used in recessed cans.
Protect them outside.
Protect bulbs from the elements by placing them inside enclosed fixtures outdoors. For colder climates, look at the packaging for optimal operating temperatures.
