The Tipping Point for Compact Fluorescents

Fast Company magazine has an article on how Wal-Mart wants to sell at least one compact fluorescent light bulb to each of its 100 million customers ...

Last year, conversations started in Wal-Mart around the potential of swirls to save customers money on utility bills. "Somebody asked, 'What difference would it make if we changed the bulbs in the ceiling-fan display to CFLs?'" says Kerby. A typical Wal-Mart has 10 models of ceiling fans on display, each with four bulbs. Forty bulbs per store, 3,230 stores.

"Someone went off and did the math," says Kerby. "They told me we could save $6 million in electric bills by changing the incandescents to CFLs in more than 3,000 Wal-Marts. I couldn't believe it. I didn't know I was paying $6 million to light those fixtures. I said, that can't be right, go back and do the math again." The numbers came out the same the second time: savings of $6 million a year. "That, for me, was an 'I got it' moment."
