Manufacturers and environmentalists are hammering out a nationwide energy-saving lighting standard that, if enacted by Congress, would effectively phase out the common household light bulb in about 10 years. That in turn could produce major cuts in the nation’s electricity costs and greenhouse-gas emissions.
It sounds like the move has bipartisan support. The article notes that manufacturers are involved not entirely out of altruism; there’s money to be made in CFL’s, and it’s better for the industry if there’s a single federal regulation, rather than a hodgepodge of state legislation governing the transition.
