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 weren’t just a throwback – this team was on the leading edge of a new industry.

In between beer & BBQ on Magic Wednesdays and strolls in nearby apple orchards, they blazed a trail of renewable energy converts from California to Pennsylvania.

We’ve grown up since then. We’re now headquartered in a LEED® Platinum office space in the live music capital of the world. Instead of grilling out behind the office on Wednesday afternoons, we share our “backyard” with hundreds of thousands of customers.

But some things haven’t changed…we’re still on the front line of energy’s future. You won’t see many flannel shirts or sandals at our office, but we’re still passionate, driven idealists.

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 – supporting renewable energy.
