That's one of my "gotos" I think their beer is excellent for what I can get at my corner store and I feel that they at least try to be a sustainable business.
"Sierra Nevada Brewing Co. won the US Environmental Protection Agency's "Green Business of the Year" award for 2010.
The brewery is powered by solar energy, having 10,000 photovoltaic modules covering its rooftops and parking lot. In all, the brewery uses 2.6 megawatts of solar electricity on premises. It also has built a charging station for electric vehicles on its premises.
The company uses a small-scale BioPro™ biodiesel processor to convert the used cooking oil from its restaurant for biodiesel use in its delivery trucks. In 2009, it reached an agreement with a local ethanol company to produce high-grade ethanol fuel from its discarded yeast. Spent grain is sold to local cattle ranchers for livestock feed; spent water is sent to the brewery's own water treatment plant, where it is reused, mainly as drip irrigation for its fields. Over 99.5% of the brewery plant's solid waste is diverted from landfill.
The company owns one mile of railway for use in intermodal freight transport, which aids in reducing the brewery's carbon footprint. Each rail car can hold the equivalent of four semi-trailers of grain; rail transport is more fuel efficient than road transport.
