Myths of Energy – Energy Efficiency Myths: Home Edition

Blog Post created by David Feldman Champion on Nov 10, 2017

Most of us want to conserve energy for a couple reasons.  One, to reduce the power bill.  Nobody likes being surprised by a sky-high power bill every month.  And two, we want to do our part to reduce our carbon footprint.  Both are good reasons to conserve energy.  But, let’s make sure when we try to save energy, we’re really doing it, and not “thinking” we’re doing it…


Myth 1: If I turn off my appliances, I’m saving energy.


This is somewhat true.  Turning your appliances off will help cut the energy they use, but remember, electricity is still drawn from appliances that are left plugged in.  They actually have a fancy name for this.  It’s called “phantom” load.  So, here’s what you do to stop it:  Plug your appliances and electronics into a power strip.  That way with the flip of a switch you can “really” turn everything off.  And it’s easy to turn off multiple things at once.


Myth 2: My water heater and AC unit are the biggest energy suckers in my home.


They used to be.  But now due to modern improvements in HVAC equipment, furnaces and AC units only use around 48% of your home’s average energy consumption.  The real culprit? Electronic equipment, such as computers, gaming systems, and televisions.  These are what’s causing your electric bill to soar each month.  As electronic entertainment systems get bigger and more sophisticated each year, your electric bill will follow suit. 


Myth 3: Space heaters will help reduce your heating bill.


It seems logical to think you’re spending less by just heating one room, but that’s not always the case.  As we mentioned earlier, modern HVAC equipment is getting more and more efficient every year.  Many times your space heater is extremely inefficient!  And that means the amount of power and electricity it takes to power a space heater will cost you much more than simply letting your central air regulate the home’s temperature.


Myth 4: By closing the vents in unoccupied rooms, I’m cutting down on my energy costs.


This is a big trap a lot of people fall into.  Contrary to popular belief, closing vents in unoccupied rooms make your AC or heater use more energy!  Here’s why:  When you close vents, you actually affect the balance of your AC and cause it consume more energy to regulate this balance.  Central air units are built to distribute air evenly when you disrupt this balance, it can cause pressure to build up and cause duct leaks and wasted energy.
