Pat Shingleton: "Keeping Cool, Staying Hot..."
Experts recently analyzed three variables: heating and cooling degree days, appliance efficiencies and power plant efficiencies. Their investigations verified that air conditioning runs almost entirely on electricity, while heating is fueled by oil and natural gas. Environmental Research Letters reports that when comparing the energy necessary to keep homes livable, residing in a warm climate is more efficient than cold locations. Comparisons were made of Miami and Minneapolis whereby Minneapolis uses 3.5 times as much energy as its Florida counterpart. A typical air conditioner is four times more energy efficient than a typical furnace. Researchers contend that it takes less energy to cool a room to one degree than heating it by one degree.
