How much energy can I save by using a compact fluorescent light bulb?
A. The savings are generally five times the regular incandescent light bulb. CFLs are such a source of energy savings that some countries, such as Australia, have announced plans to ban incandescent light bulbs as part of their strategy to reduce emissions linked to global warming. In Wisconsin, 14% of homes have CFLs, but only 6% of the light fixtures in those homes have the energy-saving bulbs, according to the Energy Center of Wisconsin.
