Twin Oaks seeks to be a model of sustainability.[3] The average Twin Oaks member consumes fewer resources than the average American due to the community's practices of resource sharing[1] and self-sufficiency.[16] Members hold all resources in common except for the personal items they keep in their bedrooms. For instance, members share housing, a fleet of 17 vehicles, and a large "clothing library".[1][3][12] Twin Oaks members consume 70% less gasoline, 80% less electricity, and 76% less natural gas per capita than do their neighbors.[
