I feel your pain, but justt a head's up about Green Mountain. We switched when they first came to Texas & got SCREWED royally! I really liked the idea of the wind mills & clearer air, too, however, like most socialistic tree huggers, they don't know how to be capitalists for flip & messed up our billing every single month for 6 months. THEN, when we'd had enough, they had the gaul to come back after 2 or 3 months & tell us we still owed them monney, even though they admited to messing up the billing! It was the most frustrating experience. So, unless they know how to bill now, I'd steer clear.
