Discovery Education: Fluorescent Lights

January 10 is National Cut Your Energy Day. In this video Bill Nye, the Science Guy, explains how the incandescent light bulb is an energy hog. He gives a little history about the bulb and how it works. He then explains fluorescence and how it works in a tube. He explains how the new compact fluorescence lights work and why they can help save tons of energy. He does talk about the mercury in the light and why that can be a problem, but he encourages us to find ways to use the CFLs and then recycle them responsibly.
