Challenge Details

  • Refrigerators and air conditioners are the largest consumers of energy in American homes today.
  • The average home air-conditioning system costs $280 per year to run

Hot enough for you? Soon we’ll be staring at the dog days of summer. That’s the brutally hot part of the season when seas boil, wines sour, dogs grow mad, and everything else living slows to a sweaty crawl or slow slither. The sun is high in the sky and the days are long. Locusts buzz, asphalt softens, and children beg for freezer pops. Sounds like an ideal time for that technological marvel — air conditioning. But instead of refrigerating your house enough to make you put on a sweater in July, how about cooling it just a little less, saving some electricity, and cutting down on your carbon emissions? You and the kids can still have the freezer pops.

This Featured Challenge is based on a number of great Challenge suggestions from our Challenge Workshop. We particularly want to give credit to Elizabeth Elephant, meriicheri, and jacky4president_60546 for their Challenge suggestions.

The Carbon Connection
It takes a lot of energy to cool things down. So it should be no surprise that refrigerators and air conditioners are the biggest users of electricity in the typical American household. Air conditioning alone is responsible for about 16% of the average household’s annual electricity bill. That comes out to nearly 2800 kilowatt hours (kWh) of electricity per year for homes with central air conditioning and 950 kWh for households using room air conditioners (i.e., window units). At an average nationwide cost of 10 cents per kWh, that average air conditioning system costs $280 to run each year. Many systems cost much more.

Of course, how much you use air conditioning partly depends on where you live and how many days a year you need your home cooled. New England has short summers. A home in New England with central air might only use 1500 kWh per year. However, Florida can be downright hot most of the year. A home in Florida with central air might use over 4000 kWh of electricity each year. And the more electricity you use, the more carbon dioxide gets released into Earth’s atmosphere.

Remember, electricity most often comes to you from power plants that burn coal, oil, or natural gas as fuel to generate electricity. Burning that fuel releases CO2 into the air. So in terms of your own personal carbon impact, the biggest users of electricity have the greatest negative carbon impact. That average American household central air conditioner uses enough electricity each year (2800 kWh) to cause the release of over 2 tons of CO2 into the air.

Getting It Done
One way to reduce the carbon impact from air conditioning is to do without. However, that sounds drastic — and honestly rather uncomfortable. Using the air conditioner for fewer hours can cut down on the amount of electricity it uses. So can turning up the thermostat. Each degree higher you set your air conditioner’s thermostat allows it to use 1 to 3% less electricity.

Need help meeting this Challenge? Here are a few suggestions:

  • If your house or apartment has central air with a programmable thermostat, you won’t have much problem carrying out this Challenge. Simply raise the temperatures that you already have programmed for the summer months by two degrees. For example, if your thermostat is set at 74 degrees F. during the day, you want to raise that to 76 degrees.
  • If you don’t have a programmable thermostat, get one! It will control your furnace in the winter and your air conditioner in the summer and allow you to use the right amount of heating or cooling when you want it. For example, if you aren’t home during the day, don’t use the air conditioner! Don’t believe the old myth that leaving the air conditioner on all day, even while you’re away, uses less electricity than turning it on when you get home. Not true! Program the thermostat to turn the air conditioner on an hour before you get home. The house will be nice and comfy and you will have saved hours of wasted electricity cooling the house for just your philodendrons.
  • Some room air conditioners (window units) also have programmable digital thermostats. However, if your room air conditioner does not have a thermostat with specific temperatures, just do your best to turn the Hi/Low or Warmer/Cooler settings so that the air conditioner runs a little less.

There are many other ways to reduce your electricity needs during the summer. Here are a few other ideas for keeping cool and reducing CO2 emissions:

  • Help your air conditioner run more efficiently. Clean or replace your air conditioner’s air filter every month when it’s in use. The harder the air conditioner has to work sucking air through that filter, the longer it runs and the more electricity it uses. If possible, put your room air conditioners in windows that are either facing north or are in the shade from trees or an overhang. A window air conditioner that is sitting in direct sunlight uses 5% more electricity than it would if it were shaded. For other ideas on making the most energy-efficient use of your air conditioning, see Mr. Electricity’s 32 Super Tips for Saving Money on Cooling.
  • Work with the weather, not against it. In many parts of the country, nights are cool even in July and August. If the air temperatures outside gets colder at night than the temperature set on your thermostat, then you are better off shutting down the air conditioner and opening the windows. Buy a thermometer so that you know the air temperature outside. When you see it’s cooler outside the house than inside, it’s time to open those windows.
  • Fans are your friends. A ceiling fan doesn’t use much electricity and the added air circulation it provides can help you keep your air conditioner set at a higher temperatures. Make sure the ceiling fan is reversible and that it blows down in summer and up in winter. Window fans and floor fans also make you feel cooler by getting the air moving or by helping move cooler outside air into the house at night. A large fan running for 24 hours might only use 2 kWh of electricity. Your central air uses 42 times that amount! Clearly it’s OK to run that second fan.
    How do you keep cool in the summer and still save on electricity? Have you tried any of these methods yourself? What sort of difference did you see in your electric bill? Share your experiences with fellow Rallyers in the Discussion section below.

Rules of the Challenge
This Challenge asks you to raise the temperature setting on your air conditioner by 2 degrees for one week. For instance, if you normally have your thermostat set at 74 degrees, you would raise that to 76 degrees. Those of you who have window air conditioners without digital thermostats will need to approximate by turning the cooling setting “back” a click or two. Carbon credits for this Challenge are for one house or apartment; if members of your team all live in the same place, only one of you should sign up and take credit for this Challenge. This Challenge is repeatable until the AC season in your area comes to an end.

See the Math
Due to the big differences in how people use their air conditioning in different parts of the country, the numbers were a bit harder to crunch this time around. Let’s look at the known or estimated numbers being used for this Challenge:

  • According to the Department of Energy’s Energy Information Administration, the average American household (house, condo, or apartment) with central air conditioning used 2796 kWh of electricity in 2001. A household using window air conditioners used an average of 950 kWh.  source
  • However, the above numbers are a national average. And we all know that people living in Tallahassee, Florida need air conditioning more hours a day and more days a year than they would if they lived in Nashua, New Hampshire. So we’re striking a balance and spending our statistical summer in the Heartland. For the purposes of our calculations, we are using data from EIA’s East North Central region, which includes Indiana, Illinois, Michigan, Ohio, and Wisconsin. The average household in that region used 1621 kWh of electricity for central air conditioning or 712 kWh if they had window units.  source
  • No matter where you live in the continental United States, summer is still summer. And that means that the months with the greatest needs for air conditioning are June, July, and August. For Atlanta, 24% of the energy needed for cooling is used in August. For Dallas, that number is 22%. And for South Bend, Indiana that number is 26%.  source
  • In the East North Central region, 71% of the households with air conditioning have central air and 29% use window units. Based on those percentages, we will use a weighted average of 1356 kWh of electricity used per year for cooling in the East North Central region, which includes South Bend.  source
  • Now let’s calculate the amount of electricity used for cooling by the average household in South Bend in the month of August. Multiply the weighted average yearly electricity use for air conditioning (1356 kWh) by the percentage electricity used for air conditioning in August (26%), which gives you 353 kWh.
  • Setting your air conditioner one degree higher allows your air conditioner to use 1 to 3% less electricity. Let’s average that number to 2% per degree and then double it to 4% since the Challenge asks you to raise your thermostat by 2 degrees. (Feel free to go for more! If you normally run your central air at 73 degrees and raise your thermostat by 5 degrees to 78 degrees, you could save up to 15% of the electricity you would normally use for cooling.)  source
  • Applying the 4% savings to the 353 kWh of electricity normally used for air conditioning in August gives you a savings of 14 kWh, or 3.5 kWh per week. At a national average of 10 cents per kWh, that’s a dollar savings of $0.35.
  • On average, generating 1 kWh of electricity results in 1.55 lbs of CO2 emissions.
  • Saving 3.5 kWh of electricity therefore reduces carbon emissions by 5.4 lbs of CO2 (14 kWh x 1.55 lbs CO2/kWh) for the week.

We know all of you Rallyers don’t live in South Bend, so your numbers will vary. (And don’t worry! We’ll run a heating Challenge next winter and you can all iron out the regional scoring inequities!) No matter where you’re drinking your lemonade this summer, we think you’ll find that 2 degrees warmer isn’t that big of a difference to your overall comfort. Try 4 degrees, and see if you can live with that. Over an entire year of cooling, you could be save hundreds of pounds of CO2! And that’s a chill that fits the Rally bill.

I'm joining late to this challenge; it's Sept. right now and the temperatures are slowly cooling. I live in Florida however, so this challenge still applies as we are having 90- 93 degree weather right now. I'm going kind of extreme with my thermostat set on 80 instead of 76/77.

Croe about 6 years ago
Here in Bonnaroo Country it is hot(100+) & humid(85%)but we use our programmable thermostat and only have the AC down to 75 or 76 when we are home to enjoy...when you come in from the heat such a temperature feels rather good! I hate seeing folks jack the air down then put on a sweater or wrap in a blanket... we do similarly in the wintr, keeping the temp low and wearing clothes!
carbonkat about 6 years ago
ok I live in Arizona and it has been averaging around 105-110 degrees for the past few's HOT, but I usually keep my air at 80 and have moved it up to 85 degrees and just aclimated to it! No Problem!
MarylandGreenPower.Com about 6 years ago
Ha! We keep our air conditioner set at 78-80 when it's this hot (today it 99 degrees!) outside. We've got some great tips for further increasing the efficiency of your air conditioning on our blog at Maryland Green Power dot com. One of them is a very simple water misting device which cools the air near the AC condenser by 10 degrees by using a mere cup of water per day! That adds up to a huge efficiency increase. Google "Maryland Green Power" for more tips!
CerridwynEldritch over 6 years ago
I hate the heat - and I live in Southern California so I'm constantly getting hot. I wish it would rain a lot instead. I'm told I should move to Seattle. Maybe some people say you "get used to it" and "don't even notice it after a while"... bull. I always notice and I often get a headache as well. We haven't been turning on the a/c for a while though (here, it's common to turn the a/c on in January - no joke.) So... I figure I might as well take this challenge while it's still a tiny bit cool so I don't die of heat stroke or something in the actual summer months.

Well it is October, I think I will just not cool the house. We don't turn on the heater until November 1st... California weather
kjw3214 about 7 years ago
I keep my house at 80 degrees during the day when I am home, 82 if we leave and 78 at night with a programmable thermostat. I am use fans to cool the house and always try to remember to turn the fan off when leaving the room.
rallyer29107 about 7 years ago
I don't ever use my programable thermostat because it would cost me more. I turn the A/C on when I wake up or get home, and turn it off when I leave. Thus, its never running when I'm not there, or when I'm asleep and don't need it. Sure, my house can be a bit hot when I get home, and it can take 30 - 45 minutes to cool down, but that's much better than cooling it for an hour before I get home, or before I wake up. Plus we get home at such different times that I don't want it on for hours when we stay out late after work. Why use a programable thermostat when you can save much more without one?
i'm really going to try and stick to this. i can do this but my family might complain. oh well. i have a programmable one and a lot of times when it's cool outside we open windows instead of fans or AC.
EM-Assistant over 7 years ago
This challenge only lasts 7 days? C'mon, can't you make it last 28 days like other challenges. I like the 28 days because it helps remind me to do things. But every week is a bit much. I have a programmable thermostat. No need to check it every week.
hyperlocavore over 7 years ago
I don't use AC...
deedeeddd over 7 years ago
seeing how i am 8 month pregnant and ready to pop going with no ac at all is a little far fetched for now. we do go with out the ac or heat in the winter but Florida summers can be hot. During the day we always keep the ac at 78 so it never goes above 80. we do use fans to help cool it off a bit. at night we do splurge a little and set the ac at 74 so now we will be moving it up to 76 at night
Stan over 7 years ago
No more AC for us! We just moved are ready to kick the habit with this challenge. It can be a little toasty at night, but nothing a fan can't solve. In fact, I remember being in 90+ degree temperatures at night (in other lands) and I just learned to deal with it, and/or I directed a fan right on me when doing to sleep and slept fine.
peacerally14 over 7 years ago
I open the windows because fresh air is better. We don't have an AC anywhere in our house for the effect that it destroys the ozone. So when we're not home we turn off our central air
arashi_cloud over 7 years ago
I usually open the windows and or doors to let a circuit of air waft through my room.... I also use a window fan in place of air conditioning when it gets too hot for even those to work- it works great.
scarletrox17 over 7 years ago
73 to 76 :D
kj over 7 years ago
I finally stopped using the air conditioner completely during the week. I open the windows when I get off of work at night, and close them when I go to bed. The breeze cools the house off just fine for most of the hot summer nights and feels more natural than having an air conditioner blasting anyway.
Lilcoco over 7 years ago
da only time i use my AC is during night time, and i always turn it off as soon as i wake up and open the windows=]
Enviro_Geek over 7 years ago
I replaced my (apparently) broken thermostat with a digital, programmable one. Immediately I noticed results - and now my home maintains an even, comfortable temperature - all for about $40!
janlcg over 7 years ago
I don't have AC in my house, but I pledge not to use AC in my car.
activist_hippy over 7 years ago
I accept this challenge and I will continue to not use my AC!!!! Honestly, it's not that hard. Go swimming, have a cold drink, sit in the shade where there's a breeze. I survive every summer without AC and I know you can too!!!
aschram13_75060 over 7 years ago
We started the AC about a month ago, and the thermostat is set at 78 for now. But when the temperature rises above 100, we also raise the thermostat to 80. Also, if the temperature is under 80 at bed time, I open the windows until I get up.
Stinkbug over 7 years ago
No AC in San Francisco. The fog is my AC.
rallyer25030 over 7 years ago
We do not use an AC either. People try to give us their old ones but we always turn them down. I like having active, outdoorsy kids. When you have AC people do not want to be bothered by the heat and tend to stay inside. I will never have my kids say to me they don't want to play outside because it is too hot! (I have actually had people say they don't want to come to visit because we don't have AC and it's too hot. HOW PATHETIC!)
rallyer27745 over 7 years ago
I have not used my AC yet, I'll raised the temperature to 76 degrees when I use it.
Bubble Butt over 7 years ago
I always keep our AC at like, sixty five degrees. But when it is really hot, we just open the windows, and put on all our ceiling fans.

I never use my Air Conditioning, it utilizes gas and reduces milage. If you live in an area like Bonners Ferry you shouldnt need Ac anyways, its to cold this time of year and in the summer its good enough to just roll down your window a little.

greengiant about 8 years ago
Having our thermostat at 78 is sufficient. It is usually 80-mid 90s outside in the summer months in Durham, NC so 78 seems comfortable. On nights that the temp is below 70, we turn the AC off and open the bedroom windows and use the ceiling fan. WE are glad to minimize our carbon footprint. Greengiant
pghinaudo1_78217 about 8 years ago
The cost of electricity almost doubled about two months ago and, after my roommate and I picked ourselves up off the floor, we raised the temperature on the AC up about 8 degrees. I have since bought 4 air purifiers and a couple of fans. Now we can put the AC up above 80 even in Central Texas and it is cool. The air purifiers also help with my allergies. More than anything the amount of energy we are using was cut in half and our cost is back down.

ZD about 8 years ago
I guess I can accept this too, although I don't need to change much for it---I almost always turn the AC off when I am away during the day, and have it running for three hours or so after I get back from work. Also, I get cold very easily---_very_ easily---so I keep the thermostat at 80. At 75 I would be uncomfortable. (No, really.) I cannot turn it up to 82, because my rental agreement actually says "keep it between 72 and 82". It will be harder for me to do the winter challenge, but I'll try.
yeseniaemt about 8 years ago

john_wuenschel about 8 years ago
Just replaced the 30% efficient heating unit-A/C with an 80% efficient heating unit-A/C, installed a programmable thermostat, replaced the sliding door and single pained window and added insulation in the attic. 2 tears ago I started keeping the thermostat at 78 in the summer and 65 in the winter (the dogs and cats are fine with this). All of the changes made a big difference. The gas bill is almost half of what it was last summer. This was easy, expensive but easy. The hardest thing to do was to trade in my p/u truck but the FORD is getting 29 mpg in the city, which is almost double.
MsAnneThrope about 8 years ago
This one is easy - we don't have our window unit hooked up right now. We would have except the windows in our new place are funky and we haven't figured out a way to safely put the window unit in yet, and we haven't been in big rush to figure it out. IF we had it in, it would only be on for a couple of hours per day on low to bring the temperature down a bit, not to make the house a refrigerator. I don't like extreme heat or cold in the first place, so running the AC 24/7 isn't for me. I can make it a bit more of a challenge by not running the AC in my car at all....which I only do to cool the interior when I first get in the car anyway. This challenge is easier for me than for some of you though, as I'm in Michigan, not in Florida or Texas. It'll even out during the winter months.... :0)

This one was so easy I am taking it again. Go to bed with your windows open, folks! You'll never get a better night's sleep!!! Carry on....
greeen sheeep about 8 years ago
I try to use the AC as little as possible. I am lucky to have a yard full of large shade trees that help cool the house. I keep all curtains on the east windows closed in the morning until the sun has passed. Since these two 10 foot wide windows are in the main living spaces it really helps us stay comfortable without the air on. Keeping the doors to the solarium closed is also a huge help. It's at least 20 degrees warmer in there! If I could figure out a way to keep the upstairs bedroom cool we could ditch the AC all together.

Queen of Green about 8 years ago
Once again, I am confused. I thought we were only supposed to accept these challenges if we were going to alter our behavior to align with the suggestion. Therefore, I thought that I can not participate in this Challenge as I do not use air conditioning. Never have. Never will. Thankfully I live in Maine, so air conditioning is unnecessary. Recently I discussed this proposition with our local supermarket, but to no avail. Now that I have specific numbers, I shall try again. Stay green and keep the challenges coming.
Son_of_the_Celts about 8 years ago
I was able to convince my roommate to adjust the thermostat higher [by at least 7 degrees!] when we are both away during the day. We started this a couple of Months ago! We usually get home around the same time, so then it is adjusted back. Figured that we didn't need to have the whole place cool the entire day, and the temp inside the place is cool enough for the cats.

Houston, we have a Rallyer! Nice work Crazedkitty for being the first to adjust your AC.
