Here's proof changing to CFL light bulbs worksTopping the list of most green tips is changing your incandescent light bulbs to compact florescent bulbs (CFLs).  Since most people who change to CFLs are also taking other measures to cut down and conserve, most people aren’t real sure how much it really works.  Dominion Virginia Power’s(DVP) compact fluorescent light bulb instant discount program is showing the savings.

Our CFL discount program is helping Virginians reduce the amount of energy they use, thereby saving money and helping the environment," said Paul D. Koonce, chief executive officer of Dominion Virginia Power. "It is an effective, easy way to practice energy conservation.

Dominion Virginia Power is offering the instant discount program as an incentive to its customers to promote CFL usage.  As such, the program has discounted individual CFL bulbs by $1.50 and packs of three CFLs by $3.00.  The discount program is offered through Home Depot stores in the DVP area.  Rather than issuing coupons either online or through the mail, the discounts are already reflected in the shelf price of the bulbs at participating Home Depot stores.  The program was begun in October of 2007 and is set to end December 31, 2009 but the power company expects it to be resurrected in 2010 because it is working so well.

About 3.8 million bulbs have been purchased through the program.  The energy savings from those bulbs is estimated to be one billion kilowatt hours.  Customers of DVP should save “$150 million in energy costs over the life of the bulbs”.  The 3.8 million bulbs purchased will the equivalent effect of:

  • 149,037
    cars off the road for one year
  • 854,725 ton C02
    life cycle air pollution reduction
  • 1,113,648,413 kWh
    life cycle energy savings
  • $160,006,033
    life cycle savings

Along with the CFL discount program partnership with DVP, Home Depot also provides CFL recycling nationwide.  Any unbroken CFLs that have run out of juice can be handed to the person behind the “Returns” counter.

Compared to other frequently mentioned methods, replacing incandescent bulbs with CFLs is one of the cheapest ways of cutting down on energy consumption.  Whether you live in Virginia or not, incorporating CFLs into your energy conservation and cost savings plans is well worth it.
