In her renewable energy project, Phillips got help from the Vermont solar company SunCommon and Vermont's major electric company, Green Mountain Power.
GMP has been pushing to be a leader in the search for the Holy Grail of renewable energy — economical batteries to store energy from wind farms and solar panels for those times when the sun doesn't shine and the wind doesn't blow.
In an interview last year, the company's CEO, Mary Powell, told The Associated Press that batteries would be a linchpin in a newly envisioned future for electrical energy. They would store solar energy and provide backup power during outages and put electricity on the grid at times of peak demand and recharge electric bicycles.
All signs are that it's happening.
Phillips is one of 20 GMP customers to have installed Tesla Powerwalls — 70 more are in the queue. GMP charges $37 a month over the life of the battery, or allows customers to buy them up-front for about $7,000 installed.
