This report examines the broad topic of energy use and its relationship to lifestyles. The emphasis is on three energy conserving lifestyle models: (1) the rural alternative lifestyle; (2) new towns; and (3) energy conserving subdivisions in existing cities. The first chapter presents an introduction. Chapter two examines the back-to-the-land movement, looking both at individual homesteads and communal living. Chapter three examines developer-designed new towns, such as Reston, Virginia and Irvine, California for energy conservation possibilities and lifestyles. Chapter four considers energy conservation in existing communities including: (1) voluntary conservation measures; (2) insulation of buildings; and (3) the microclimate within the subdivision. The final chapter identifies and evaluates obstacles to the wider adoption of energy conserving lifestyles. (Author/MR)
