Energy Efficiency
Air conditioning can only be accomplished by using electricity.
On the other hand, there are many ways to heat your home. You can burn wood or pellets, which release heat energy; you can use natural gas or propane, which is a fuel that is burned in a furnace to release heat; you can use electricity in baseboards, wall heaters, or electric furnaces, or you can use electricity in a heat pump, which is essentially an air conditioner that can be operated in reverse (moving heat inside instead of outside).
