Whether you’re gut-renovating your entire kitchen or just considering switching out a few elements, knowing which appliances suck up the most electrical power can help you make smart purchasing and remodeling decisions.
Check out this list of common kitchen appliances and their electrical energy costs.
In terms of energy usage, microwave ovens range from 600 watts to a whopping 1500 watts, but because these appliances are used for short periods of time, their overall yearly energy use is lower than what their pull would suggest.
If you use a microwave for about an hour-an-a-half each week for forty-eight weeks, the overall yearly energy usage will be on average 90 kilowatt hours (kWh).

In contrast to microwave ovens, refrigerator/freezers pull anywhere from 150 to 400 watts, relatively small amounts. But because refrigerators are used 365 days a year, 24 hours a day, their yearly consumption can vary between 720 and 1800 kWh for older, inefficient models.
An electric oven can pull a blinding 2000 to 2500 watts of power, but like the microwave, it’s not used constantly. Assuming it is used as frequently as the microwave (for comparison purposes), an electric oven consumes about 160 kWh yearly.
Stovetop hoods are going to vary widely in energy usage, somewhere between 70 to 150 watts. Using the same frequency of use as ovens and microwave ovens, the yearly energy consumption of a stovetop hood would be about 25 kWh.
A dishwasher pulls about, on average, 1200 watts of electricity. Calculating the yearly consumption, however, varies greatly depending on whether you use an energy saver cycle or the ultra-hot, ultra-long scouring cycle, plus whether your household water is heated by gas or electricity. For comparison purposes, the yearly energy consumption, using the standard of 48 weeks of 1.5 hours of usage per week, will vary between 290 kWh and 790 kWh.
Whether you have a simple coffee maker or an elaborate espresso machine, your energy draw for such an appliance will vary between 500 to 1000 watts. However, coffee machines tend to be used minutes a day. Rough calculations for their yearly consumption depends on how much an addict you are, but can vary between 13 kWh and 42 kWh
Whenever you’re switching out old appliances, it’s wise to check out the Energy Star ratings for their replacements. Designed to work just as well but a lot more efficiently, Energy Star appliances offer long-term benefits, including lowering your home’s carbon footprint. In addition, even a small reduction in energy consumption can make a big difference, over time, in your electricity bill.
