For Residents » Save Energy It takes just a little energy to save on energy costs. If you pay attention to the little things, the money you save will add up in a big way. The chart below gives you a good idea of energy costs per electrical appliance, kind of like nutrition fact labels on food.

An electric resistance heater has a COP of 1 GPM - Gallons per minute SEER - Seasonal Energy Efficiency Ratio (efficiency given to central air conditioning)

EER - Energy Efficiency Ratio (efficiency given to window/wall air conditioners) Solar and Green PowerAir conditioning is cool, but fans are cheap. When Willis Carrier invented the air conditioner in 1902, he sparked a national love affair with conditioned air that grows stronger every year. According to a decade of research conducted by a Florida state energy agency, only 1 percent to 2 percent of the population today would prefer to live without air conditioning. Of course, that’s just what people did for centuries. During the latter half of the 19th century, fans, particularly ceiling fans, were the creature-comfort technology of the era. Once the air conditioner came along, though — along with initially cheap electricity to run it — the populous was hooked. Today fans continue to provide home cooling -- and without sapping the large amounts of electricity needed to run air conditioners. The High Cost of Chilling Out Air conditioners, even the most efficient, newest models, occupy the top of the home energy consumption pyramid.

In a typical household on a normal summer day, no other single appliance consumes as much electricity as the air conditioner or comes close. During cooling season, fully one-quarter of the utility bill goes to fund the sole function of keeping cool. An average single family residence will consume just over 2,800 kilowatt-hours of electricity per year to run air conditioners. In the United States, air conditioning alone consumes 5 percent of all electricity generated in the nation and costs homeowners $11 billion per year. Truth In Numbers At the average national electricity cost of 12 cents per kilowatt-hour, a typical window air conditioner running 12 hours per day uses 335 kilowatt-hours per month and costs around $40 monthly to operate. A 2.5-ton common residential central air unit uses around 1,300 kilowatt-hours per month and costs just over $150. Now consider the humble fan. A midsize ceiling fan set on high for 12 hours per day costs just over a penny per hour in electricity or just about $3.50 per month.

A higher revolutions-per-minute box fan adds just about $4.40 to your monthly electrical bill. In many homes, the cost of powering either fan for half of each day can be offset by the savings gained from simply switching incandescent light bulbs to compact fluorescent bulbs. Circulation Vs. Cooling Consuming mass amounts of electricity to run an air conditioning compressor isn’t required for home comfort -- up to a point. Moving air in the home with a fan can keep occupants acceptably comfortable at temperatures up to 85 degrees. The effect of increased air circulation on a hot day is based on the same principle as chill factor on a cold, windy winter day. Fans augment the action of both convection and evaporation to cool humans. Moving air dissipates the heat of metabolism, convecting it away from the body. Meanwhile, the evaporative effect as perspiration dries cools the skin. The Combo Approach Fans and air conditioners are not necessarily mutually exclusive in today’s home. In fact, using a ceiling fan in conjunction with an air conditioner has a place in a strategy for both energy conservation and home comfort.
