When it comes to saving energy and electricity, there is a ton of information available online. But many of the things you read are absolutely not true. Here are the most common myths when it comes to saving energy and electricity.
Myth: During the summer, leaving your air conditioner on all day will actually cost less than turning it on periodically to cool down your house.
Truth: Many people believe that during hot weather, the solution is to leave the A/C running all day at a higher temperature (around 78 degrees). But the truth is, running your air conditioner all day will consume far more energy than just turning it on periodically to cool down the house. The opposite is true as well (using the heater during cold conditions).
Myth: Taking a bath wastes more energy than taking a shower.
Truth: It depends, actually. The most important aspect in this debate is the type of showerhead being used. If you are using a less efficient older model showerhead, you could consuming as many as five gallons of water per minute. Doing the numbers, if you take a seven minute shower, those 35 gallons would equal the amount of water you would use in an average bath. On the flip side, if you are using a low-flow showerhead, the water usage would be cut in half.
Another important aspect to consider is how much hot water you are using during your shower. While you may be using less water because of the low-flow showerhead, you could be using more energy from your hot water heater depending on how steamy your shower is. Chance are, the amount of energy used to heat an actual bath would be less than taking a long steamy shower.
Myth: Turning light bulbs back on after they have been off actually consumes more electricity than just leaving them on.
Truth: This statement is absolutely false. Some people believe that the surge of electricity consumed when turning a light back on is far more than the amount of energy consumed while it is powered on. But truthfully, the amount of electricity consumed when you flip a light on is not measurable. In the end, it is absolutely always cheaper to turn off the lights when they’re not needed.
Myth: When it comes to using the washing machine, there is no real difference in using hot or cold water.
Truth: This is absolutely false and it may (should) change the way you do your laundry from this point forward, especially if you do many loads a month. An average load of laundry using the hot or warm setting costs about $0.69. Doing that same load using cold water costs about $0.14 — a savings of $0.55 per load.
We have all been taught that hot water works best when washing white clothing so it would be difficult for many to switch to cold water just to save half a dollar. However, you can now purchase laundry cold water laundry detergent which would eliminate the need to use hot water altogether.
How much energy are you wasting by using hot water during an average laundry cycle? If you were to run one load of laundry per day using the hot water cycle, that would waste as much energy as leaving the refrigerator door open 24 hours a day for an entire year.
