I say good thing! I don't have a system yet but I will  I live in a rural area with the space. Space being the key word. Thinking about it for the planet def..comes down to economic problems, but also the space prob. how much energy is produced related to the space it takes up...a single home needs at least 10 kw system to have heat in the climate you need it in and aircondition in the other climates. But right now rural areas def have the space in there back yards for a tower or panel room on the roof, cities yes wind power is impossible to have private systems on each residents but larger producing mills would work for subdivsions. and such... they pretty much pay for them selves in about 5 years. and have little maintenance. And of course are green energy....but yet they still seem quite expensive ...why?profit margine I would assume like anything else...Anyway people ! like to hear about your system and how good it works (pros and cons) and how much the power company's are paying you for unused power generation going back into the lines....
