How much electricity does a typical coffee maker use?
A typical coffee maker uses between 600 to 1,200 watts during the brewing process. The wattage consumption depends on the model and features of the coffee maker. Standard drip coffee makers generally fall within this range, while specialty machines, such as single-serve pods and espresso machines, may use more energy.
To estimate the total energy consumption, consider how long the machine operates. For instance, if a coffee maker uses 900 watts and brews for 10 minutes (1/6 of an hour), it consumes about 0.15 kilowatt-hours (kWh) of electricity for that brewing session. Over time, this can add up, particularly for daily coffee drinkers.
Do coffee makers consume power when not in use?
Yes, many coffee makers consume a small amount of electricity even when they are not actively brewing coffee. This phenomenon is often referred to as “phantom” or “standby” power consumption. For example, programmable coffee makers that have a clock display or keep the heating plate warm may draw power continuously.
While the standby power usage is relatively low compared to active use, it can still contribute to your overall energy bill. To minimize energy consumption, consider unplugging the coffee maker when it’s not in use or investing in models with low standby power features.
