Anheuser-Busch's Fairfield brewery has been working to improve energy efficiency for years, and they did not slow down in 2006. Two major projects were initiated that will save a combined 900,000 therms of natural gas and almost $1 million, an 11% reduction. Both projects involve unique heat exchange and recovery in the brewing process to provide steam heat, reducing the need for gas-generated heat. The upgrades were accomplished through a partnership with Pacific Gas & Electric (PG&E).
