Energy Tip-Ceiling Fans

Do you know which direction your ceiling fan should turn in order for it to do its job and be economically efficient?

Just the other day I had a friend of mine ask me this question, she was wanting to know for her house about the direction of her ceiling fan. I thought I knew the answer, but did some research to verify.

My short answer was this: During the summer, you should run the fan so that the breeze blows downward. This will create a wind chill effect, just like you get when you roll down your car windows while driving to cool you off. During the winter you should leave the fan off.

Durning my research I did however find some ceiling fan manufacturers websites suggesting that you run the ceiling fan so it blows downward in the winter. This idea is based on the fan mixing the warm air collecting at the ceiling and moving it back down to the perimeter of room in the winter, which would make the room warmer and need less heat from your furnace. But not trusting this advice, (remember ceiling fan manufacturers want the fans running continuously so they will eventually fail), I dug on and found some information on consumer reports that suggest that the draft caused by the fan can have a chilling effect on people in a room, in the winter. This leads to them turning up the thermostat and using more energy. So they too recommend that you not bother to reverse the motion of your fan—just leave it off during heating season. Note that there might be some situations where reverse operation would be beneficial, such as in a room with a wood stove running or a very high vaulted ceiling.

If you’re looking to lower your energy bills during the cooling season, use ceiling fans in rooms you are occupying and turn up the temperature on your A/C a few degrees and let the fan go to work. Remember that ceiling fans cool you and not the space you’re in, so turn them off when you leave the room for an extended time so as to not waste electricity.

Here is a ceiling fan shopping tip I ran across: Consumer Reports found that while the pricier fans did have fancier finishes, they didn’t necessarily provide better performance. What’s more, most fans performed similarly in their air-movement tests. I will tell you though that my kids' rooms have cheaper fans and very rarely get used due to the noise factor, where as my living room and bedroom fan gets used quite often and are very quiet in comparison.

Thanks Marsha for making me do some research; I hope this is helpful.

Green Tip- Beverage Packing

Well summer is here and a lot of times nothing sounds better to me than a nice cold drink. This is also a Holiday weekend so I thought I would share some interesting information that I found out about beverage packaging.

Did you know that the energy required to produce a single twelve-ounce aluminum can from virgin ore (new aluminum) is enough to produce nearly two new twelve-ounce glass bottles. That's right it takes twice as much energy to make a can versus a bottle. So the next time you buy a six pack of your favorite frosty beverage, opt for glass bottles over aluminum cans. The manufacturing energy conserved could power my Brother-in-Laws television setup through two Sunday, NFL game days. If 10% of beer drinkers replaced a six-pack of cans with six glass bottles, the energy saved could fly thirty thousand US Soccer fans to South Africa to watch the USA take on Ghana. Maybe then with all those extra fans the US would have came out with a victory.

So if you are planning on stopping by my house this weekend and want to treat me to a drink, Coors Light (bottles) will do.

Have a safe and happy 4th.
