How to Reduce Energy Consumption

The incandescent lightbulb should be a called a "heat bulb," because 90 percent of the electricity we put into it comes out as heat. Light is only the byproduct. Changing to compact fluorescent lamps (CFLs) will save about $70 per bulb. To maximize the benefits and reduce the chance of buying a bulb that won't fit, take the following approach.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Lighting Catalogs
• Paper And Pencil
• Tape Measure

1. Take a lighting inventory of your home. Write down the fixture location, number of bulbs and wattage, size limitations (measured from end to end), control needs such as dimmability or three-way, and any other requirements such as outdoor use.

2. Review lighting manufacturers' catalogs, which are widely available online or by calling toll-free customer-service departments.

3. Write down suitable compact fluorescent lamp substitutes for the fixtures on your inventory list. For the greatest payback, make bulbs used more than 4 hours a day your priority.

4. Shop your list at local sources such as home centers and lighting stores. For your remaining lightbulb needs, search the Internet.

Tips & Warnings

• CFL models now include reflectors, three-ways, globes, dimmables, bug lights, outdoor floods and many other styles. You should be able to replace one-third to one-half the lights in your home.
