Which electrical appliances consume the most energy at home?
Understanding household energy usage can help you make smarter choices and cut costs, say the experts from Spanish Energy
In Spain each property has a contracted potencia, which is linked to your standing charges. The higher the contracted potencia, the higher the standing charges. But you may not need such a high potencia. Reducing this down by just 1 kilowatt could save you as much as €70 per year on average!
As temperatures rise and electricity prices fluctuate, especially for those on the regulated tariff (PVPC) in Spain, many consumers are closely monitoring their energy usage. Knowing which household appliances consume the most electricity is the first step in making practical adjustments that can reduce bills without compromising on comfort or convenience.
Appliances with the highest consumption
The refrigerator is by far the most energy-consuming appliance in the average home. While it does not consume the most per hour, its round-the-clock operation accounts for around 20% of a household's electricity bill, averaging over 500 kWh per year. During summer months or family gatherings, its energy use may increase even more due to higher loads and frequent door openings.
The washing machine is another heavy consumer. Although it may only be used for about 30 hours a month, it still accounts for roughly 10% of the electricity bill. Consumption can rise significantly depending on the use of hot water, longer washing cycles or high-speed spins. Energy-efficient models and eco-wash settings can offer noticeable savings.
Completing the top three is the dishwasher, which makes up around 8% of electricity consumption. As with washing machines, the actual cost depends on how often it is used, the chosen programme and its energy rating. Notably, only about half of households in Spain have a dishwasher, which partially explains its slightly lower overall impact.
Other high-consuming appliances include ovens, dryers, televisions and computers. According to the SPAHOUSEC project, a study on energy use in Spanish homes, here is how electricity use is typically divided:
- Refrigerator: 28.9%
- Washing machine: 11.0%
- Dishwasher: 8%
- Oven: 7.9%
- Computers: 7.1%
- Tumble dryer: 4.0%
- Stand-by power: 9.1%
Interestingly, stand-by consumption (energy used by devices left plugged in but not in active use) is a surprisingly large contributor. Unplugging or switching off devices completely can make a real difference.
Power ratings and practical savings
Looking at the power ratings of typical appliances helps illustrate how much energy is required at any given moment:
| Appliance | Power (W) |
|---|---|
| Refrigerator | 350 – 1,000 |
| Microwave | 900 – 1,500 |
| Ceramic hob | 900 – 2,100 |
| Washing machine | 1,500 – 2,000 |
| Dishwasher | 900 – 2,300 |
| Oven | 1,200 – 2,300 |
| Heating | 1,000 – 2,500 |
| Air-conditioning | 900 – 2,000 |
| Television |
150 – 400
|
Devices with the highest power demands include ovens, washing machines, air conditioning units and electric heaters. Their impact on your bill depends on both their wattage and how long they are used.
At the lower end of the scale are appliances such as vacuum cleaners (approx. 38 kWh/year), irons (108 kWh/year), toasters and razors. However, even small devices can drive up consumption if used frequently or for extended periods. Hairdryers and straighteners are notable examples due to their high power requirements.
While every household is different, becoming aware of your appliance usage patterns is a simple and effective way to cut energy costs. Consider investing in energy-efficient models, using shorter and cooler wash cycles, avoiding stand-by mode and running dishwashers and washing machines only when fully loaded.
Even small adjustments, when made consistently, can lead to meaningful savings, especially as Spain continues adapting to new electricity pricing models.
