For your viewing pleasure I will combine two things I greatly enjoy: Beer and the Environment. When breweries make it a priority to reduce their impact on the environment and try to give back, only great things can happen. Here are a select few that are doing just that; enjoy, and feel free to suggest other breweries that are making a difference (I know there are many more out there).
- 1000 square feet of solar thermal collectors. The collectors produce around 2500 therms per year and Central Waters will save between $1.4 and $1.5 million over the life of the system.

- The brewery also uses a radiant floor heating system and more energy efficient lighting systems
- They also work with local farmers in order to recycle the grain used in the brewing process. The spent grain is taken by the farmers and used as feed for livestock, and also as a compost.
- In February 2012, Brewery Vivant was honored with the first Silver LEED certification awarded to a microbrewery in the U.S. and also published their first sustainability report. (triplepundit.com)
- The brewery offsets 100 percent of its energy usage through purchasing renewable energy credits (RECs)
- They choose to deliver their beer in aluminum cans. Cans protect the beer from light, oxygen, and other factors that could negatively affect the taste. Cans are also easier to transport and are more easily recycled (54% of aluminum cans are recycled in the US, vs 36% of glass bottles being recycled).
- Very aggressive economic, social, and environmental goals that put them on the fast track to being a leader in the microbrewery industry. Some of those goals include:
- Zero waste to landfill
- 50% of food inputs from within 250 miles and 25% of beer inputs from 250 miles
- 10% onsite renewable energy generation
- Employee profit sharing program
- They completed what is now one of the largest privately owned solar installations in the country in December of 2008. They currently have a carport array that has a potential output of 503 kW DC and they also have a rooftop array that produces an additional 1.42 Megawatts DC. They also have an array on the daycare facility that has a potential capacity of 5.18 kW DC and another array on the rail facility that can produce 14 kW DC. All-in-all, the solar systems at Sierra Nevada are capable of producing 1.94 Megawatts DC. (Sierra Nevada Environmental Stewardship)
- Sierra Nevada also produced another first when they installed hydrogen fuel cells in 2005, the first brewing operation in the United States to do so. This system consists of four 300 kW fuel cell energy units that can produce 1.2 Megawatts DC when combined. You can check out their real time power production here.
Fuel Cells at the Sierra Nevada Brewery
- Sierra Nevada implements many other energy efficiency and sustainable practices including:
- Ultra efficient lighting system and the use of daylighting
- The recycling of waste heat
- They divert 99.6% of solid waste from the landfill with a goal to reach 100%
- HotRot Composting System – providing compost for their hop field, restaurant garden, and employee garden area.
- Use homegrown ingredients in beer and restaurant.
- Transportation – They utilize a hybrid electric local route truck, constructed a rail car unloading facility near their plant to reduce the negative impact of transportation, and also utilize the spent vegetable oil from their taproom and restaurant to power their biodiesel transportation fleet.
