Knowing the energy cost of our appliances is crucial to make informed decisions about how we can save energy and reduce the electricity bill. There are different methods to measure the consumption of the washing machine, dishwasher and air conditioning, among others, accurately.
How to know the energy consumption of household appliances
On the market there are devices called “electric consumption meters” or “energy meters” that are connected between the plug and the appliance. These devices measure the amount of electricity consumed by each device in real time and display the results in kilowatt-hours (kWh).
Many appliances, such as refrigerators, washing machines, and air conditioners, come with energy labels. These labels provide information about the energy efficiency of the device and its estimated consumption in kWh per year. By comparing labels, you can choose more efficient appliances and save energy.
In some cases, the manual for the appliance may contain information about its energy consumption. Look for the technical specifications section or check the manufacturer’s website for more details.
In the case of Spain, household appliances are subject to energy labeling regulations in accordance with Directive 2010/30/UE and Royal Decree 110/2015. These establish the requirements for the energy efficiency labeling of different devices, allowing consumers to make informed decisions about their purchase.
Some electric companies offer online programs or applications that allow you to calculate the consumption of your appliances based on their use and the time of operation. These tools can be useful to get an approximate idea of the energy consumption of your devices.
Smart devices, such as smart plugs and smart bulbs, can provide data on electricity usage and control the run time of your appliances remotely.
In addition to the energy consumption in kWh, it is important to take into account the power factor of your appliances. It indicates how an electrical charge converts energy into useful work. Appliances with a low power factor can consume more energy than necessary.
Additionally, it is essential to adopt habits of efficient use to reduce energy expenditure. Some helpful practices include turning off appliances when not in use, taking advantage of low-power programs on washing machines and dishwashers, and using energy-saving LED light bulbs.
National Energy Efficiency Action Plan
In Spain, energy efficiency is a priority and is promoted through the National Energy Efficiency Action Plan 2021-2030 and other initiatives. These plans seek to reduce energy consumption and promote the responsible use of resources.
Some power companies offer rebate programs for efficient energy use. These programs can provide financial incentives to consumers who reduce their consumption during certain hours of the day or during periods of high demand.
Regulations on energy efficiency
Appliances are also subject to requirements to reduce consumption in standby mode. According to Directive 1275/2008/EC, devices must consume less than 1 watt in standby or off mode. This helps avoid wasting energy and lower your electric bill.
In addition to regulations for household appliances, Spain also has regulations on energy efficiency in buildings. Royal Decree 235/2013 establishes the minimum requirements for energy efficiency in buildings, which include aspects such as the thermal envelope, lighting, and heating and cooling systems.
In short, know the electrical consumption of your appliances that allows you to make informed decisions to save energy and money in your home. Use electricity meters, energy labels and calculation programs to obtain accurate information. In addition, adopt efficient use habits and take advantage of the energy efficiency regulations and programs in Spain to contribute to caring for the environment and reduce your electricity costs.
