This unnoticed energy drain can lead to higher electricity bills over time. Coffee makers can contribute to phantom load, especially those with built-in clocks or programmable features. Even when not brewing, they use a small amount of energy.
How Much Energy Does a Coffee Maker Use?
While the amount of electricity consumed may seem negligible on its own, consistent power drain can add up. Most coffee makers use about 800 to 1200 watts when brewing coffee, but a plugged-in coffee maker can draw only a few watts when not in use. This may seem trivial, but it becomes significant over time, especially in households with multiple appliances plugged in.
Estimated Annual Cost
To give you an idea of how costs can accumulate, below is a simplified table of estimated annual costs based on a coffee maker with an average phantom load of 5 watts:
| Usage | Cost per kWh | Annual Cost |
|---|---|---|
| 5 watts plugged in continuously | $0.12 | $5.26 |
While $5.26 annually may not sound like much, factoring in multiple devices can lead to a more significant expense over time.
Impact on Coffee Quality
Another essential aspect to consider is how leaving your coffee maker plugged in can affect the quality of your coffee.
Heating Elements and Freshness
Coffee makers typically have a warming plate to keep your coffee hot after brewing. However, prolonged exposure to heat can adversely affect the flavor of coffee.
- Bitter Taste: Over time, coffee that sits on a warming plate can develop a bitter flavor from constant heating.
- Aroma Degradation: The warmth can cause the natural oils in coffee to evaporate, leading to a decrease in aroma and taste.
Best Practices for Optimal Coffee Quality
If you love great coffee, consider these suggestions:
- Brew only what you need: To minimize waste, brew coffee in smaller batches that match your consumption.
- Transfer to a thermal carafe: Instead of leaving your coffee on the warming plate, transfer it to a thermal carafe to maintain the temperature without exposure to heat.
