1. Reducing contracted power, a double-edged sword
Your contracted electrical power, also called "fixed term", is measured in kW (kilowatts) and is the maximum amount of energy you can consume at any one time. The more power you have contracted, the more appliances you can run at the same time. The less power you have, the more likely it is that “the switch will trip”.
If you analyse your habits and decide that you don’t need to run so many appliances at once (maybe you can live without using the oven and the vacuum cleaner at the same time), you might consider reducing your contracted power. The less contracted power you have, the lower your electricity bills.
For an average household, reducing power by a decimal (from 3.4 to 3.3 kW, for example) will save about 40 euros a year . Let's look at a specific example:
- A customer who switches from 5.75 kW to 3.3 kW and has the Tempo Happy Rate will save about 118 euros every year.
The problem is that lowering the power is not a decision you should take lightly . It is true that the lower it is, the more you will save on your bill. But reduce it too much and your electricity will cut out whenever you turn on the ceramic hob. If you rush in and reduce the power too much, then you will have no choice but to increase it again to live a normal life. All these procedures can be expensive and eat up any savings you have made in other ways. We recommend the following content to learn how much it costs to change contracted power and how to do it.
2. Concentrate the energy in your house
Most of us give little thought to the way we use our homes. We just use the different rooms according to a series of cultural habits passed from generation to generation. So, most of us eat in the dining room, living room or kitchen, and wouldn't consider eating in our bedrooms.
Other people leave doors open, close the curtains at noon and always set the thermostat at 22ºC, all habits to which we don't give a second thought.
That’s why we want to set you a challenge: stop thinking of your house as a whole that is always on or off. Think again and consider it as a set of different rooms, with different uses that consume energy differently. If you heat only the room you are using and close all the doors, you can halve your bill. After all, what is the point of heating the bathroom or the guest room if you are going to spend the afternoon in the living room? Let's look at a specific example:
- A person who works at home and wants to save energy. In a 75 m 2 home, the difference between heating the whole house and heating only the 15 m 2 room where you work means a saving of 80% on the most expensive item in the bill, the 50% spent on climate control that we mentioned at the beginning of the article.
3. Closed doors, open mind
It is very important to close doors, even in parts of the house you don't use. If a room opens onto a corridor that has a door to the main hallway (common in large houses), keeping both doors closed creates an intermediate air chamber similar to those found in high quality windows. Artificial insulation that absorbs losses.
We’ve already mentioned our grandmothers, who not only turned off lights around the house but also kept unused rooms closed. These habits are common in the elderly, particularly if they lived in rural areas highly dependent on a central fireplace for air conditioning: each open room cooled the heart of the house.
