We are renovating a 28 year old house and wanted to go eco friendly. Through my extensive studies I found it would take 8 to 10 years to pay for itself using geothermal or solar/wind and at that time it would most likely need to be replaced. Our plan now is to ensure we are capable to go this route in the future when its 90% cheaper and the Govt. is willing to jump in with some major contribution, instead of a few hundred $ here and there. Let us know what you decide and pics for the inquiring mind.
