This morning outside my work it was about 70 degrees and sunny. The weather was quite literally TOO good. So we turned off our air conditioning and opened the windows to air out the office. As the cool outside air came rushing in, my brain gears started turning, and I wondered to myself, “Self, if every house in the U.S. of A. turned off their A/C and opened their windows whenever the weather was nice outside, how much money and electricity would that save?”

Welp, let’s see. The average price in the U.S. for energy is 9.49 cents per kilowatthour. And the average home air conditioner uses “more than 2000 kilowatt-hours of electricity per year, causing power plants to emit about 3500 pounds of carbon dioxide and 31 pounds of sulfur dioxide.”

Okay, stay with me. According to the OFFICIAL ENERGY INFORMATION ADMINISTRATION, in 2005 there were about 93.3 million American houses with air conditioning. So let’s figure that those houses are in places that have nice weather (65-80 degrees) about 20% of the time, or 70 days each year.

That means that if all those houses turned off their air conditioning on those days and opened their windows to let in the fresh air, then:
400 kwh per house * 93.3 million houses = 37.2 billion kilowatthours saved!! That equals out to savings of over $3.5 billion each year! Ay chi wa wa.

Of course, the actual amount of nice days could vary, but still, if everyone did this whenever the temperature was nice outside, we’d be saving billions of kilowatthours. Dang, crazy.

So next time you’re at work or at home, and the weather is nice, instead of cranking on the ol’ air conditioning and wasting energy and money, why not just open the windows and let some fresh air in? You’ll be saving money and electricity while getting some fresh air in your cave.
