So, we went along and did US taxes yesterday evening (oh joy :-) I noticed that there were credits for various home energy-saving measures; we claimed a few things such as new doors.
I was kind of surprised that they didn't want to know who made the doors, or the name of a professional company who installed them etc. - all that mattered was the receipt for the parts involved.
Does that mean in future I can homebrew my own solar heater or wind turbine (both of which were on the list) and claim for the parts used? Or for things like that do they in fact ask for a product name, company who came and installed it etc.? (I think for the doors it mattered that it was energy-star approved, so maybe that's how they "get ya")
Curious, anyway - I might get around to making a solar pre-heater for the water this year...
cheers
