Green energy supplier recommendations

I've done a bit of research on green energy suppliers for this area. Hve any of you had particularly good or bad experiences with a green supplier? Reviews on Clearview indicate low initial rate with huge increase afterf initial contract plus monthly add-on fee that seems to increase. I haven't been able to access other supplier reviews except ford ease of sign-up :( Thanks in advance, Diana Bloss (Duquesne Electric)
