Dominion covers a $1.50 discount on single bulbs and $3 on multi-packs of the compact fluorescent light bulbs, which last up to 10 times longer, but are more expensive than regular bulbs. Dominion estimates that a 60-watt energy-efficient bulb will save a typical Dominion customer $54 before it burns out.
The Dominion discount comes off automatically at the register at 33 Home Depot stores, including the locations on the Peninsula. Dominion initially wanted to sell 1.4 million bulbs by the end of 2008, but it now plans on announcing a higher goal and more participating stores for the program in 2008.
