A Little Background

It all started in central Vermont back in 1997. Our founders were a tight-knit family of flannel-wearing, sandal-footed, long-haired, tree-huggers. But they were more progressive than throwback – blazing a trail of renewable energy converts from California to Pennsylvania, on the leading edge of a new industry.

We’ve grown up since then. Instead of afternoon beer & BBQ behind the office on Magic Wednesdays, we now share our “backyard” with hundreds of thousands of customers.

But some things haven’t changed. We are still passionate, driven idealists on the front line of energy’s future, and every day we’re joined by more dreamers who believe they can make a difference in the world by starting with one small, simple step – choosing renewable energy.
