Use fans. Moving air creates a wind chill effect that cools your body. Ceiling fans are a great option to take the edge off hot summer days and use less energy than air conditioning units. Ceiling fans make a room feel cooler for its occupants by circulating warm air up and cool air down.
A ceiling fan can actually help lower your electricity bill. By circulating air in a room, a ceiling fan can make a space feel cooler, so you may not need to run your air conditioner as often. That can lead to lower electricity bills in the summertime.
Ceiling fans use 0.6 kWh to 0.9 kWh per day in electricity and are an energy-efficient way to cool your home, typically costing less than 20 cents a day to run the fan all day long. Central air conditioning is a far more expensive cooling option, costing nearly 50 times more to run than a ceiling fan.
Ceiling Fans for Cooling
Since ceiling fans do not actually lower the temperature in your home, you may be asking what it is they can do. However, they can play a very important role in making your home feel cooler. In fact, turning on a ceiling fan can make your home feel about 4° cooler than what it really is.
Cooling yourself with a fan vs. an air conditioner is significantly more energy efficient and cheaper. Fans use around 1% of the electricity consumed by air conditioners. You could leave a fan running for 24 hours and still use less energy than 15 minutes of air conditioning.
During summer months, your ceiling fan blades should be set to spin counterclockwise. When your ceiling fan spins quickly in this direction, it pushes air down and creates a cool breeze. This helps keep a room's temperature consistent throughout the day and reduces the need for an air conditioner to run constantly.
Heating and cooling: 45-50%
The largest electricity consumer in the average household is your heating and cooling appliance. By a long shot. Central air conditioners and heaters use tons of energy in order to keep your home set to the right temperature.
Instead of running your AC at 72 degrees, a fan allows you to set your thermostat to 78, yet still feel as if it is about six degrees cooler. A fan costs pennies per day to operate versus dollars per day for the AC.
Generally, TVs use between 50 to 200 watts (W) of electricity, depending on the model. Most TVs use less than one amp and connect to a 120-volt outlet. Older TVs that use technology such as Plasma and CRT are much less efficient compared to newer LED and LCD TVs.
Although it could run for over a 24 hour period, it is still best to turn off your ceiling fan when you are at work or out of the house for an extended time to give the ceiling fans' motor a rest and reduce electricity use and cost.
In this case, the answer is easy: run your fans and air conditioning at the same time. The air movement from a ceiling fan helps to keep the air from stratifying into hot and cold regions. Therefore, you avoid the cold feet/hot head effect that can otherwise happen.
The living room is a perfect place for one. Ceiling fans are also valuable in bedrooms. Cool air circulating while you sleep can improve your rest.
The Disadvantages of Ceiling Fans
One of the downsides of ceiling fans is how noisy they can be. If you're trying to relax in a quiet room, the whirring sound of a ceiling fan can be distracting. And if you have a low ceiling, you may find the fan is too close to your head, making the noise even more noticeable.
The short answer is that it depends on your kind of television and how big it is. It's also important to consider how long you're leaving your TV on each day. The more hours it's on, the more electricity it's using.
They work by blowing air around your body, which lowers the temperature of your skin by about six to eight degrees. Because electric fans use electricity, you might be wondering if they can run 24 hours a day. The answer is Yes.
Unless you are physically in the room while the fan is on, it's not doing any good. If you're not there to benefit from the ceiling fan's air circulation, then you're just using more electricity. If your air conditioner isn't operating efficiently, then your ceiling fan isn't doing it any favors.
Heating and cooling are by far the greatest energy users in the home, making up around 40% of your electric bill. Other big users are washers, dryers, ovens, and stoves. Electronic devices like laptops and TVs are usually pretty cheap to run, but of course, it can all add up.
According to the U.S. Department of Energy, standby power accounts for as much as 5% to 10% of residential energy use, and homeowners could save $100 to $200 each year on utility bills by unplugging devices that aren't in use.
The ceiling fan direction in summer should be counterclockwise to help create a downdraft, which creates that direct, cooling breeze. Your fan direction in winter needs to be clockwise to create an updraft and circulate warm air around the room.
There is one good reason to leave the fan on, at least in summer. According to the Energy Star website, “dialing up the thermostat by only 2 degrees and using your ceiling fan can lower air-conditioning costs by up to 14 percent over the course of the cooling season.”
