The Orion, Mich., plant has actually used landfill gas since 1999 to heat a portion of the paint shop. By the time the new equipment is installed, landfill gas will account for 54 percent of Orion's energy usage. At the Fort Wayne, Ind., facility, the gas will cover 40 percent of the plant's energy usage.
"...allows us to act as our own utility," explains Bill Mortimer, GM co-generation project manager. "Not only does this help us save on energy costs, but it limits the amount of greenhouse gas released into the atmosphere."
GM has previously explored other green energy technologies to reduce costs and emissions. At the automaker's Detroit-Hamtramck facility, which produces the Chevrolet Volt, a 264,000 square-foot solar array helps power portions of the plant, saving an estimated $15,000 per year.
Other automakers such as Honda and Nissan have also explored alternative energies at their factories -- such as solar arrays and wind turbines.
