Hi Foks - I had several kind folks reply to my request for experience using green energy suppliers. 4 folks using and happy with Green Mountain -I signed up with them though they are a bit expensive (100% wind, pollution free 8.89c / kWt) One used Green Mountain then switched to Arcadia for lower rate One uses Brighten Energy (100% green - 7.39/kWt) - not long enough for a review A friend of mine rents solar panels which not only pays for her household electrical use but often results in a profit - - benefit of ranch style houses with flat roofs and S SW sunlight :) Thanks to all who responded.
