I have had this advice offered to me several times by several people:

 

”Don’t turn off your AC but set thermostat to a higher temp like 74F but leave AC on to save electricity.”

 

This is a myth. You don’t save by maintaining constant temperatures. Turning off AC or setting thermostat temp to very high like 88F - which is same as turning off AC - will save you in energy costs.

 

Same is true for cold weather with temperature values/settings in reverse. Programmable thermostats are convenient feature will not necessarily reduce power usage.

 

What are some perpetuating myths that you have heard.

 

Temperatures here are very high this week. I got burnt by my own watch yesterday. :-(

Programmable thermostats can save you money if you program them right. At the $DAYJOB we have Nest thermostats throughout the building, all set to turn on at 7 AM and shut down at 5 PM. We set an eight degree temperature swing summer and winter. Seems to work well and according to Nest we do save money.

 

One myth that I saw busted on Mythbusters was lowering the tailgate of a pickup truck to "decrease drag" and get better gas mileage. One that could be considered a myth now but was true up until the 1980's was you burned more gas when driving with the AC on instead of rolling down the windows. Now, AC compressors are highly efficient and don't drag on car engines like they used to.

I never believed that AC reduced gas mileage significantly. Some people leave the AC always on in cars even in winter with heat on or climate control on auto.

I read that he wasn’t short but 5’7” is still below average for France.

And see that is how myths get perpetuated.  5'7" was above average height for males in France in 1800 which is when he ruled.  Obviously modern day heights in France are irrelevant to the time period he lived/ruled in.

 

In 1800, the tallest race on Earth was the Cheyenne Plains Native Americans.  And they averaged like 5'9".

I'm old enough to remember the "Carter Gas Lines" and announcements in the papers and on TV telling people to not use their AC in the cars, but to roll down the windows. Of course that was back in the days of R-12 freon.

When we were in high school it became obvious that you could separate the guys who were going somewhere from those that weren't by observing them driving on a hot day.  

 

The guys with promise had the AC running in the car.  The ones without much of a future were driving around with the windows down and their shirts off.

Are you saying/predicting poor guys remain poor?

 

What happened to guys driving around shirtless with AC on? :-)

When  I was in high school the only kids with cars were the ones good with mechanics that bought junkers and fixed them up. They made money on the side by fixing up other's car's.  And back then AC was pretty much non-existent. I learned to drive with my dad's '46 black Ford but that was at the end of my senior year. Didn't have a car of my own until after college. My 60 CC scooter busted a chain and I walked into town to get another one. Saw a Mazda dealer and left with an RX-2.
