It's no secret that auto manufacturing is a power and resource-intensive business. From the metals and plastics that go into new vehicles to the numerous machining and finishing processes, assembly plants consume tens of millions of dollars' worth of energy a year. Hoping to be a better environmental steward, General Motors has announced the installation of landfill gas generators at its Fort Wayne, Indiana, and Orion, Michigan, assembly plants.

The Fort Wayne plant, which manufactures the Chevrolet Silverado and GMC Sierra, has been using landfill gas since 2002, and with the upgrade will derive as much as 40 percent of its power from electricity generated with landfill gas. The Orion Assembly facility, which makes the Buick Verano compact sedan and Chevrolet Sonic subcompact hatchback, will get 54 percent of its energy from landfill gas once the upgrades are completed.

The installation of the on-site generators is part of GM's goal to increase its use of renewable energy to 125 megawatts by 2020. Fort Wayne and Orion combined will generate 14 megawatts. The Fort Wayne facility was recognized as an Energy Star-certified facility by the EPA for its energy management. The landfill gas power generators are expected to come online in May 2014.
