If you want to go fully off the grid in Vermont, the local utility--Green Mountain Power--will help. In a first-of-its-kind service, the utility offers an energy-efficiency audit, suggests solar and battery technology, and then charges a flat monthly fee. Those who want solar and battery storage but want to stay connected to the grid can also work with the utility, which offers products like the Tesla Powerwall 2 in monthly billing rather than an upfront fee. By adding batteries to individual homes, the grid gets stronger--in times of peak demand, rather than turning on an extra power plant, the utility can draw from the network of batteries and avoid emissions. Green Mountain Power was also the first utility to be certified as a B Corporation, meaning it meets rigorous standards for social responsibility. It brought its second microgrid solar and storage facility online in June.
