A small drip coffee maker (4 or 5 cups) typically uses 550 to 900 watts, while a larger model uses 750 to 1200 watts. A single-serve brewer that uses coffee capsules (like a Keurig or Nespresso) uses 900 to 1500 watts of power. And an automatic espresso machine uses between 1000 and 1500 watts.

Tip:A modern coffee maker will use approximately one watt of power in addition to the energy used for brewing. This equals to 24 watts a day and 8.76 kWh a year, which is not a significant amount of energy use. Coffee makers are energy efficient, you can save some energy by brewing a larger amount of coffee and storing it in a vacuum flask or Thermos, instead of making single cups throughout the day.
