Being awake with the aroma of freshly brewed coffee is the best start for your busy day at work. This helps you and your team get through to mornings and busy hours to stay alert and motivated. But do you actually know how much energy it takes to boil the billy?
How much energy does one pot of coffee require?
The recommended average heat to optimize coffee taste is from about 50 °F to 200 °F which takes about 1000 watts and takes about 5 minutes. Energy cost per coffee pot=0.083 kilowatt hours.
Breaking Down Different Brewing Types by Energy Efficiency
The exact energy cost depends on the exact coffee maker you use. To make it simple, let’s distinguish between the three major types of coffee machine: the regular drip machine, the single-serve alternatives like single-serving pods and the specialized espresso makers.
- Regular Drip Coffee Pot
This is the most common type of coffee maker used in office kitchens. It uses a heat plate to both heats the water and keeps the coffee in the pot warm for up to 2 hours. It takes approximately 750 and 1250 watts per pot of coffee. The automated warming plate including an auto shut-off after 2 hours adds some energy that might seem low but will slightly increase your energy bills.
1 pot of coffee- 0.083 kWh
1 kWh: about 12 pots of coffee
- Single- Serve Coffee Machine
Single serve machines are more convenient but come with increased costs. When turned on, this machine heats all the water in the base which takes about 200 to 400 watts for every cup. With the idle power consumption, an estimate of 300 watts per cup is consumed.
1 cup of coffee -.024 kWh
1 kWh: about 4 pots of coffee
- Espresso Machine
Coffee aficionados appreciate the taste of espressos. Different brewing styles add pressure to the way hot water is pushed through the grounds. The energy needed for most espresso machines needs to be considered by the cup. It takes between 1,000 and 1,500 watts to run the machine.
1 shot of espresso -0.0156 kWh
1 kWh: about 10 shots of coffee espresso
WINNER: For a typical office kitchen, the most efficient coffee machine to use is Regular Drip Coffee Pot.
Tips to Save Energy while Brewing Coffee:
- Turn – off the machine
Standby mode takes a large part of energy consumption regardless of the brewing method used. Turn-off the machine once the pot is empty and unplugs to minimize latent energy.
- Keep the machine clean
The water tank builds up mineral residue over time that impedes the heating function. Clean your coffee maker at least once a month.
- Buy an Energy- Efficient Machine
Look for machines that are energy efficient with automated shutoff function or has lower watt usage.
- Use Reusable Single Cup Filters
Single – serve machines use a lot of energy and wastes produced by pots and plastic pods. Go green by using reusable filters to minimize costs.
- Experiment with Cold Brew
During summer and warmer weather, it makes sense to combine coffee addiction and need for refreshments. Cold brew doesn’t require heat to make one.
Now that you know how much power it takes to brew your office coffee, you can take these steps to minimize its impact on your expenses without compromising your team’s comfort.
