Did you know that fridges are the most energy-consuming electrical appliance in the home? That the television Standby consumes as much as a fully operating computer? And that the iron is the small appliance which produces most power peaks?

Electrical appliances are responsible for more than 50% of electricity consumption in the home. Being aware of the cost of each one of them will help us take efficient measures to save on our bills.

According to the “Study on energy consumption in the residential sector in Spain” of the IDEA (Institute of Energy Diversification and Saving), Spanish homes spend an average of 990 euros per year on energy consumption, of which 546 euros correspond to electrical appliance consumption. The appliance that consumes the most of all?

The fridge: using 30% of the total energy.

Choosing an efficient fridge when we first purchase it can help us save a lot of money. Even though the initial outlay is higher, the investment is paid back in a short period of time as it is compensated with electricity saving throughout the appliance’s useful life. To give one example: a class A+++ fridge may consume approximately 80% less energy than a class D fridge>/span>. Throughout the appliance’s useful life, this means avoiding the atmospheric emission of one and a half tons of CO2 and a saving of more than 1,000 euros.

The television is another appliance which consumes most in the home with more than 12% of energy. And one of the main guilty parties of this consumption is the Stand by. This ‘phantom load’ -in the television alone- uses as much electricity as a fully operating computer.

As regards other electrical appliances, the oven consumes 8.3% of the total energy bill, the washing machine and the dishwasher 11.8% and 6.1% respectively, and the computer 7.4%. Choosing a class A+++ washing machine may consume almost half the energy as a class D. This translates into a saving of more than 500 euros in the electricity bill. Furthermore, it would avoid the emission into the atmosphere of half a ton of CO2, and the consumption of more than 35,000 litres of water.

In terms of kilowatts-hour, the Organization of Consumers and the User (OCU), details that the electrical appliances that consume most are: the fridge with 662 kWh, the freezer with 563 kWh, the television with 263 kWh, the washing machine with 255 kWh, the tumble dryer with 255 kWh and the dishwasher with 246 kWh.

Learn to save in your electricity bill

Once we have identified the electrical appliances that consume most in the home, it is vital to take simple and routine measures that will make us save many euros in our electricity bill.

  • Fridge. It is important not to leave the door open to avoid the motor from overworking. Putting in very hot food increases the effort the fridge must make to cool it down and consumes more. Keeping it in good condition allows us to save 25% of the energy consumed.
  • Televisions and computers. Those appliances incorporating LED technology consume 25% less than LCD and up to 40% less than plasma screens. It is very important to always switch off the standby.
  • Washing machine. Using short programs and cool washes or up to 30º (most of the energy is used to heat the water) will help us save electricity and use less water. It is better to put the washing machine on when it has a full load.
  • Oven. Try not to open the oven when it is switched on. Every time the door is opened it loses at least 20% of the energy accumulated inside. Another piece of advice: cook the largest number of foods at a time.
  • Dishwasher. Use short programs and at a low temperature to save energy. Do not forget to always fully load it and regularly clean the filter.
  • Tumble dryer. Try to switch it on just occasionally and with a full load. The best thing you can do to reduce your costs: hang your clothes out to dry in the sun.
  • Cooker. You can take advantage of the residual heat of the electric cooker or glass ceramic: switch it off five minutes before finishing the cooking and you will save energy.
  • Iron. The iron is one of the small electrical appliances whose high power can give rise to significant consumption in the bill. Try to iron the largest amount of clothes at the same time.
