Hello K.,
I say 'google' NSTAR Green and read up on the company. It does appear viable, but there are still questions to ask of them. The 'down side' to wind power is the loss of flying creatures that are struck down by these fans. Our nation's bat population is being wiped out in many parts of the country...one may think, "bats? Yuck. No big deal" that is, until we notice the rise in all sorts of virus and bacteria disease carried by billions of uneaten mosquitos. Harmony. Nature has it all figured out if we would only respect the basic laws of BALANCE. There are solutions the wind powered companies are fully aware of BTW. There are ways for them to modify the turbine speeds during times in the early evening hours to allow for less damage to the flying creatures such as swallows and bats that feed in early evening...it becomes a community grassroot project however, as any monitoring of the environment means more cost to the company, and like any big business, green or not, money is most often the focus. I'd like to believe that we will some day change this attitude. It begins with people like you and I...one blade of grass side by side makes a meadow...;) Good luck. Be Peace, N.
