- Each kilowatt reduction in contracted power enables a monthly saving of 5 euros to be made, while a degree of difference in air conditioning or turning off appliances that are not being used allow an 8% saving in a home's consumption to be achieved.
Efficient energy consumption is essential not just to reduce our ecological footprint, but also to achieve savings in our energy bill, especially in the summer months.
By following simple advice it is possible to achieve a significant saving in household energy consumption and Endesa has provided several useful tips at: this link.
Consejos para alcanzar la eficiencia energética en el hogar en verano.
Adaptation of contracted power
Knowing what power we really need in our home is essential, because each kilowatt of unnecessary power equates to a monthly saving of 5 euros. There are many platforms that enable us to find out what power we really need, but it is very easy because what matters is not the size of the home, but how many electrical appliances we require at once.
The average of the electrical appliances that consume the most is as follows: refrigerators (22.4%), freezers (19.1%), washing machines (8.6%), dishwashers (8.3%), dryers (8.6%), oven (7.8%), TV (8.9%), computers (5.8%), standby (7.8%), others (2.6%).

Air conditioning
Keep the air conditioning thermostat at 26º. Lowering by one degree increases energy consumption by 8%. In addition, if we use fans instead of our air conditioning, we are reducing energy consumption by 10%. On top of this, an energy saving of up to 60% can be achieved by installing awnings over windows and insulating the walls of your home.
In summer: "disconnect" your habitual residence
The best advice is to unplug all unnecessary electrical appliances. The list of devices to consider can be very long indeed: microwave, oven, blender, coffee machine... and in the living room: TV, router, phone and laptop chargers, etc. These are all devices that consume power even when they're not being used. This is what is known as phantom consumption and can account for between 7% and 11% of a home's total energy consumption.
In the case of your refrigerator, its consumption can be cut even if it cannot be disconnected because there is food inside . Both fridge and freezer are most energy efficient when they're almost full. So it's advisable to fill the gaps with tupperware filled with water and set the thermostat to the lowest possible cold setting. As the door won't be opened on many days, the cold will be kept inside, keeping the food nice and fresh. In this way it is possible to achieve around a 6% energy saving for each degree increase.
The same goes for your electric boiler. If hot water comes from an electric boiler, switching it off can save up to 25% of your household's consumption during holidays.
Changing habits
We all have to be responsible and consume the energy we need, without wasting and being efficient. This efficiency involves changing when we use some appliances, such as our washing machine or dishwasher, which can be programmed in off-peak hours, at night or first thing in the morning.
