Abstract
Abstract A heating and cooling system for an enclosure utilizing electricity generated from wind energy. The system may include a windmill mechanically linked to a plurality of low voltage electrical generators. The electricity is supplied to a plurality of thermoelectric devices which effect heating and cooling of the enclosure. The system is thermostatically controlled and can be employed with existing heating and cooling systems as the primary source of heating and cooling.
