Landfill Gas Cuts GM Natural Gas Consumption ...
GM lowers natural gas consumption through the use of landfill gas makes progress in its renewable energy goals. Sharon Morton, GM Communications, provides update on General Motors 
efforts. ...
... "General Motors has reduced its natural gas consumption by 21 percent since 2000 and is expected to achieve its goal of a 25 percent energy reduction by the end of 2006. The sum of landfill gas capacity at the seven GM operations using the fuel is equivalent to the energy needed to heat over 25,000 households, which represents about 1.6 trillion BTUs per year. Each landfill gas installation at a GM plant generates annual savings of greater than $500,000. " ...

DOE on Landfill Gas: "Methane, on the other hand, which is less soluble in water and lighter than air, is likely to migrate out of the landfill. Landfill gas energy facilities capture the methane (the principal component of natural gas) and combust it for energy. "
Environmental Protection Agency - LMOP: "Landfill gas is the natural by-product of the decomposition of solid waste in landfills and is comprised primarily of carbon dioxide and methane. By preventing emissions of methane (a powerful greenhouse gas) through the development of landfill gas energy projects, LMOP helps businesses, states, energy providers, and communities protect the environment and build a sustainable future.
