Every year, we spend thousands of dollars on energy, but in the past few years, newer, more energy friendly light bulbs have started to show up on the shelves. So, what makes these different from the others? Starting this year, the United States may no longer manufacture or import 60-watt incandescent light bulbs. The Energy Independence and Security Act, signed in 2007 by President George W. Bush, has slowly outlawed energy-hungry lighting. Stores may still sell what's in stock, but that inventory will soon be gone forever. Halogen: These bulbs closely resemble traditional incandescents. Technically, they are incandescent. But the filament is surrounded by halogen gas, which glows just as brightly while using less electricity. The full story on the Christian Science Monitor.
