Still using incandescent light bulbs? If so, you're wasting electricity and your electric bill will no doubt show it. Fluorescent lighting is far from new, but the way the bulbs are shaped, is. There was a time when you couldn't buy a fluorescent light bulb to fit many existing lamps and fixtures. Someone must have heard us complain, because now you can find fluorescent bulbs in almost any shape and size. A simple and effective way to watch your electric bill go down measurably is to simply change light bulbs from incandescent to fluorescent.

Many Americans began purchasing electric light bulbs in the late 19th century due to the widespread adoption of electric power infrastructure, particularly following the establishment of power stations. Innovations in electric lighting technology, such as Thomas Edison's development of a practical incandescent bulb in 1879, made electric lighting more accessible and efficient. Additionally, the promotion of electric lighting as a safer and more reliable alternative to gas lamps contributed to its growing popularity among consumers.
There are many ways to lower an electric bill. Turn off any computers, televisions, and other appliances and unplug them when not in use. Replace incandescent light bulbs with CFL or LED bulbs. When replacing large appliances, look for the Energy Star label.
