It's funny that being "green" is a thing.
It's FANTASTIC and socially/environmentally responsible and great, but economically it can seem a little unattainable! I know that having a solar powered house lowers your energy bill, if not diminishing it entirely, but do you know how much solar energy costs to install? A lot! I think it's a wonderful idea to insulate your house with natural materials that are easy to breath and safe to install, but Honey, go to Lowe's and compare the difference between regular rolls of the itchy throat pink stuff and the "green" stuff...
I think being green, for me, means to use everything you have. Try and get salvaged materials and build wisely. Not only is it cost effective, duh, but it's less wasteful, duh.
Some of the down sides to buying land without an established home are obvious; no bathroom, no kitchen etc. We were lucky to have 3 existing structures, all with electricity and one with a well, a pump, a septic tank and a foundation. (Sounds like a home to me!) Another pretty miraculous thing was the junk left on the land, which they offered to clean for a few extra thousand dollars and we politely and cheaply declined. Some of that junk is junk and some of it is INCREDIBLY useful building material! (Not to mention shovels, rulers, nails and screws, other tools we don't understand yet, cool old signs, windows, doors, machinery, bric-a-brac AND a possibly working lawn mower!)
Cause we are living in a raw material world, and I'm a raw material girl.
