Blue Spruce Farm


In 2005, Blue Spruce Farm began generating power from their anaerobic digester as the first dairy in Vermont to participate in Central Vermont Public Service Corporation’s (CVPS) Cow Power Program. Today, the methane gas from their 1,300 cows is sold to the grid to supply over 300 surrounding homes with electricity.

In 2013, the Audets became the first VT farm to adopt a wind turbine, which produces 2.5MW of electricity for the farm operation and surrounding community. They also recently added a 2MW solar array on leased land. In an attempt to further reduce their fossil fuel usage, this past fall most of their corn crops were land injected. Thanks to their innovation and creative energy cycling, the Audets receive large numbers of visitors for farm tours each year, and are considered a poster child for environmental farm operations. They attribute their family culture and organized management to their willingness to experiment with new ideas and technologies.
