Here are some stats on why tiny houses are fantastic energy savers. What this does not take into account is the HUGE reduction in additional building materials (outside of lumber) and the huge reduction in STUFF needed to fill the house.
I don’t cool THO and will being next year in burning wood scraps in my mini 12. Because I was not there this year I cannot do the carbon footprint for 2014, but in 2013 it was 1.1 carbon tons – however with 10 acres of untouched forest we contribute back far more than we could ever use even with having two houses. Our forest, I estimate covers the foot print for 10 normal homes plus our own footprint.
