KUB will be participating in EarthFest on Saturday, April 21 from 10 a.m. - 5 p.m. at Pellissippi State, Hardin Valley Campus. Bring an old incandescent light bulb to the KUB booth and exchange it for a new compact fluorescent light bulb (CFL). This offer is good for the first 100 people. Limit one CFL per household, please.

KUB has been participating in EarthFest since it began in 2000. The annual EarthFest is a day of food, fun, entertainment, and lots of environmental education opportunities.Admission is free.

Eleven percent of your household energy bill goes to lighting, according to the Department of Energy. A quick way to save money on your electric bill is to switch to CFLs. A CFL can save you $40 or more in electricity costs over its lifetime. The bulbs use less energy than incandescent bulbs, produce the same light output, and last up to 10 times longer.

CFLs provide the greatest savings when they're used in fixtures that are turned on for more than 15 minutes at a time. The federal government's ENERGY STAR guidelines suggest using CFLs in open fixtures that allow airflow. Good examples of uses are in table and floor lamps, hanging lamps, wall sconces, and outdoor fixtures.
