When reviewing power use with my Emporia Energy Vue I realized one highly overlooked power consumption item in homes – motors.
Motors are everywhere – ceiling fans, attic fans, sump pumps, furnaces, air purifiers, bath vents, etc. They’re easy to overlook but really should not be overlooked if you care about power use.
Take for example the ceiling fan. A common builder grade unit can draw 60 watts of power and while that’s still more efficient than an air conditioner and can help distribute cooling/heat in a room – its not very efficient. Look for an Energy Star ceiling fan with a DC motor and you’ll draw about 20 watts for the same air moving effect.
Obviously for occasional use that 40 watt difference isn’t a big deal. Run it constantly and you’re looking at about 350kWh difference a year – that could cost you on average $45 extra per year ($28-$122 depending where you live).
Once you take care of the obvious home stuff (LED lights, etc) motors may be one of the best ROI items for swapping out. Be sure to look for DC motors and/or Energy Star logos when buying things for your home with a motor, you’ll save a lot in the long run.
