John Noble, a sixth generation dairyfarmer, got his first taste of the benefits of biogas about a decade ago, when he installed a small system on his Wyoming County farm.Now, Noble and a host of investors, including a handful of local farm families, are getting into biogas in a big way. Synergy Biogas, an entity owned by Florida-based renewable energy company CH4 Biogas, last week took the wraps off its new biogas power project, located on the 1,850-cow dairyfarm that Synergy owns in Wyoming County.
