The family farm owned by Luke, Mike and Tony Brubaker has approximately 850 cows and 700 young stock, producing 20,200,000 pounds of milk last year. It has 13 full-time employees and more than 1,500 acres of farmland. This heifer barn with it's 720 photovoltaic (solar panels), and two other buildings, have a total of 777 panels that produce 150 Kw of electrical energy. This was made possible with the help of the Dept. of Treasury. Additionally, Brubaker Farms has a methane digester can handle more than 41,859 metric tons of organic waste, to capture methane which fuels a low emission generator producing 225 kW that powers the digester and farm operations.

This provides additional revenue for the farm, and creates environmentally friendly community partnerships. USDA Photo by Lance Cheung.
