The former news magazine US News and World Report explains to the world why we can no longer have incandescent light bulbs:

The End of the Light Bulb as We Know It

The incandescent light bulb, one of the most venerable inventions of its era but deemed too inefficient for our own, will be phased off the U.S. market beginning in 2012 under the new energy law just approved by Congress. Although this will reduce electricity costs and minimize new bulb purchases in every household in America, you may be feeling in the dark about the loss of your old, relatively reliable source of light. Here's a primer on the light bulb phase-out and what will mean to you:


Why are they taking my light bulbs away?

Moving to more efficient lighting is one of the lowest-cost ways for the nation to reduce electricity use and greenhouse gases. In fact, it actually will save households money because of lower utility bills. Ninety percent of the energy that an incandescent light bulb burns is wasted as heat. And yet, sales of the most common high-efficiency bulb available-the compact fluorescent (CFL)-amount to only 5 percent of the light bulb market. Earlier this year, Australia became the first country to announce an outright ban by 2010 on incandescent bulbs. The change in the United States will be more gradual, not mandated to begin until 2012 and phased out through 2014. However, don't be surprised if some manufacturers phase out earlier.
