Nod Hill Brewery in Ridgefield is now fully powered by solar energy. Over the winter, the business worked with Smart Roofs Solar to install an array on the roof of its building, offsetting all of its electrical usage and making it the first brewery in the state to be entirely powered by solar energy. The solar panels also power the other businesses housed in the building and push a minimum of 56-hundred kilowatt hours per year back into the power grid.  Brewers Association chief economist Bart Watson says they benefit from having a reliable source of energy that reduces costs, particularly for heating boil kettles or hot liquor tanks, while also protecting the environment.
