Lakewood, Colorado [RenewableEnergyAccess.com] Ten government energy agencies and an Army base have recently teamed up to buy renewable energy credits. They will purchase renewable energy certificates for five years-accounting for 117,825 MWhs each year.The agencies include: – Berkeley Lab, Lawrence Livermore Lab and Stanford Linear Acceleratory Center, Calif.-25,000 MWh – Pantex Plant in Amarillo, Texas-2,500 MWh – Kansas City Plant, Kan.-4,500 MWh – Sandia National Laboratories, N.M.-6,700 MWh – Los Alamos National Laboratory, N.M.-12,000 MWh – Fort Carson, Colo.-40,000 MWh – Golden Field Office and Central Regional Office, Colo.-625 MWh – National Renewable Energy Lab in Golden, Colo.-11,500 MWh – Western Area Power Administration-15,000 MWh The certificates will come from biomass generation from the Sierra Pacific Industries’ sawmill sites in Anderson, Lincoln and Sonora, Calif. Certificates will also come from wind generation from Nebraska Public Power District’s wind farm in Ainsworth, Neb., and the Mountain View wind site in Palm Springs, Calif. All certificates are supplied by Sterling Planet, Inc., a third party marketer. Renewable energy certificates, also known as green tags, are the intangible environmental benefits associated with generating one MWh of electric energy by a renewable resource. They don’t require the energy to be physically delivered to the buyer, but instead offset the difference between cost of the renewable power and power from fossil energy sources. Purchasing green tags helps to meet the goals outlined in the “Greening the Government Through Efficient Energy Management” initiative. The initiative provides goals for Federal agencies to expand the use of renewable energy.
