Wal-Mart reached its goal of selling 1 million compact fluorescent light bulbs -- known as CFLs -- months ahead of schedule, and it's moving into phase 2 by launching its own low-cost bulb with General Electric.
Wal-Mart took the lead with a free-market approach to getting the energy efficient bulbs into more homes by stocking more, and stocking them at eye-level where hurried consumers are likely to see them. No doubt the extensive press about their benefits helped customers warm up to the bulbs too.
Whether or not Wal-Mart's bottom-up approach will work better than the top-down strategy that some other nations have employed -- namely, banning the old incandescent bulbs altogether -- remains to be seen, but it's a great sign to see the free market doing some good.
The Environmental Protection Agency, meanwhile, is drumming up support on a 10-city "Change a Light, Change the World" tour that kicked off yesterday.
