Though some commonly shared “energy hacks” could help you save money, there are still a lot of misconceptions out there that could be costing you. Let’s get to the bottom of some popular energy myths.
Myth 1
Leaving lights on uses less energy than turning them off.
A prevalent belief is that frequently switching lights on and off consumes more energy than leaving them on. In reality, the small amount of power needed to turn on a bulb is typically much less than what’s wasted by leaving it on.
Myth 2
Hand-washing dishes saves more water and energy than using a dishwasher.
Many people assume that washing dishes by hand conserves water and energy. However, modern dishwashers are designed to be highly efficient, using less water and energy than hand-washing. As it turns out, washing a typical load of dishes with a dishwasher uses 37% less water than hand-washing.
Myth 3
Electronics don’t use power when turned off.
It’s a common misconception that devices like phone chargers or laptops don’t consume energy when plugged in but not in use. In truth, many electronics draw “phantom” or “vampire” power even when turned off. Unplugging these devices individually or using power strips to turn off or unplug multiple electronics at once can help eliminate this unnecessary energy consumption.
Myth 4
Turning up the thermostat heats a room faster.
Some believe that setting the thermostat to a higher temperature will warm up a space more quickly. This actually wastes energy, making your HVAC system work harder to reach the higher or lower point. It’s best to set the desired temperature and allow the system to operate efficiently.
Myth 5
Closing vents in unused rooms saves energy.
Closing vents is not a good way to save on energy costs. Heating and cooling systems are designed to distribute air evenly; closing vents throws the system off balance. This causes pressure to build up, resulting in duct leaks that waste energy.
Myth 6
Smart devices waste energy.
Using more electronic devices to save energy may seem counterintuitive, but it works. Smart power strips, bulbs, and thermostats can adjust power and settings to help you save automatically.
Myth 7
Ceiling fans are only useful in the summer.
Heat rises. In the winter, your ceiling fan can help push that warm air back down to keep you cozy. Just make sure it’s spinning clockwise, which sucks the cool air upwards and pushes warm air down.
Myth 8
Lowering the thermostat when you’re away from home will save energy.
Well, that one depends. This is true for some HVAC systems, but not all. Boilers and furnaces can handle large temperature swings. But heat pumps are actually more efficient when they’re constantly running. Setting back your thermostat while you’re away could accidentally trigger your backup heating system, which is the most expensive way to heat your home. If you have a heat pump, set your thermostat to a comfortable temperature and don’t worry about turning it down when you leave.
