BACKGROUND: Operational since December 2005, the 380-foot-tall windmills are a source of alternative energy for the Atlantic County Utilities Authority. Five towering turbines produce 1.5 megawatts of energy each and omit no pollution. It's estimated the wind farm saves a total of 23,613 barrels of crude oil each year and provide enough energy to power 2,500 homes.

INSIDER INFO: The windmills work best in winds between 12 and 45 miles per hour. The blades rotate between 10 and 20 times per minute.

WHERE: The windmills are located on the ACUA's wastewater-treatment plant. Drivers can glimpse the mills from Routes 30 and 40 in Atlantic City or schedule a tour. CLICK HERE FOR DIRECTIONS.

HOURS AND COST: Tours are free and take place by request Mondays through Fridays during business hours. Schedule a tour of the windfarm or the entire treatment facilities at 609-272-6950.
