OK, scam might be a the wrong designation, but by inserting a 3rd party into your electric bill just does not sound like a good idea. I came from PA which is a deregulated state, and you can actually shop for your electric supplier. When I called SECO, they did not know anything about this "offer", which is why I initially thought scam. Now I did not go to the site, but the initial info, did not mention the additional costs. I am all for renewal energy, and in the deregulated states, this seems to work well.
Also, if the 3rd party (arcadia power) were to miss or be late on a payment, what happens, my guess your credit rating gets hit, and you may be required to make a deposit to the electric company. I believe a better solution would be to have the electric company offer a renewal rate for renewal energy.
Sorry if I caused any confusion in this matter. Bottom line if you are looking at this option, be sure you completely understand what you are getting into.
