Six-year-old Nick Keane sounded wise beyond his years as he informed one visitor at Yorkville's Green Fair about the difference between incandescent light bulbs and CFL bulbs. The Beacon-News reports he said "these aren't fuel efficient," pointing to the traditional bulbs. He then pointed to the compact fluorescent light bulb display and said, "these other ones are."

The distinction was easily apparent to Keane because of a light bulb exhibit at the fair last weekend. Visitors pedaled bicycles to see which bulbs were easier to light up using the bikes.

The Chicago-area community's second annual Green Fair offered visitors plenty of chances to have fun while picking up tips about the environment. The fair made it fun to learn about the environment with clowns who gave ecology jokes and balloon flowers, as well as recycled art-and-crafts stations.

The fair also showcased school children's projects that promote eco-efficiency. The Watershed Quilt was on display - a locally made blanket with patches created by students to depict wildlife in the area and advocate conservation.

Yorkville is not alone in its efforts to engage children with energy efficient behaviors. Schools across the nation are increasingly sponsoring teachers' e3 certification through the Ohio Energy Project and American Electric Power. Students of the certified educators receive environmentally-friendly kits including energy-saving light bulbs to start their eco-learning.
