his is the second edition incorporating additional footage. David and Sarah built a passive solar home in Upstate NY in 2002. Fifty percent of the heat the home needs is generated from the sun. Supplemental heat is obtained by burning 1 cord of wood over the entire heating season. All the needed electricity is produced by a 1 Kilowatt onsite solar electric system and a 1 Kilowatt windmill coupled with a battery bank to store power for when it is needed. This home is one of hundreds that open their doors every year for the Green Buildings Open House the first saturday in Ocotober.
