This Saturday, March 24, and next Saturday, March 31, the Bethany Neighbor to Neighbor Energy Challenge will hold two bulb swaps at the Bethany Transfer Station. Residents are invited to come exchange four working incandescent bulbs for four new energy-efficient CFLs, which could save an average Connecticut home up to $100 a year. CFLs start saving money and energy as soon as they are installed, and are an easy first step to reducing energy waste. Residents will also have the opportunity to sign up for a free in-home lighting visit from Neighbor to Neighbor at the exchange; they can then get up to 20 of the bulbs in their home replaced for free. To learn more about the program, visit www.CTEnergyChallenge.com/lighting or call the Neighbor to Neighbor office at 860-372-4406. Residents of Cheshire are also among the participating towns.
