Myth or Reality? We hear more and more about energy efficiency. We reveal truths and hoaxes so you know what to expect.
WHAT IS ENERGY EFFICIENCY?
It is an efficient use of energy. Any appliance or installation must consume less than the average amount of energy to carry out an activity if it is efficient and committed to the environment. “It also seeks to supply itself, if not completely, with as much renewable energy as possible (also called alternative energy),” according to Factor Energía.

AN EFFICIENT HOUSE PROTECTS THE ENVIRONMENT
Energy wants to protect the environment by reducing its intensity. It is important that as users we become aware of consuming what is necessary and not more.
ENERGY EFFICIENCY: HOW MUCH DOES A HOUSE SPEND?
“When we buy or rent a home we are concerned about its price, but not about the number of expenses it will entail. We should ask ourselves if the energy consumption figures can be reduced with the installation of efficient and sustainable insulation,” they explain from Rockwool. , a manufacturer of rock wool-based insulation, a material that reduces the electric bill by up to 90%.
1. FALSE: ENERGY EFFICIENCY IS ONLY FOR NEW CONSTRUCTION.
It is false that an efficient house has to be exclusively new construction. It is possible to adapt a house in rehabilitation or reform so that its consumption is reduced on a daily basis. “In Spain, more than half of the residential park dates from before 1980. Its rehabilitation presents a potential saving of up to 80% in energy demand”, indicate from Rockwool.
2. FALSE: EFFICIENT INSULATION MATERIALS ARE MUCH MORE EXPENSIVE.
Actually, this aspect of the energy efficiency of a house is a lie if you look at it in the long term. Although it is true that the initial costs to make an efficient house are slightly higher (not much more expensive), over time they lead to significant savings in the factor. You have to do a long-term study.
3. TRUE: ENERGY EFFICIENCY IS WELL-BEING.
Correct insulation makes a house more efficient and, in turn, affects people’s well-being by achieving a quieter and more thermally comfortable environment. Efficient houses also preserve health in terms of air quality, for example.
4. FALSE: ENTIRE BUILDINGS MUST ALWAYS BE REHABILITATED.
For a house to be energy efficient it can be rehabilitated “separately”. The entire building does not need to be rehabilitated. It is possible to achieve good interior insulation, which leads to savings and energy efficiency, although only the reform of a house is undertaken.
5. TRUE: ENERGY SAVING IS A GREAT ECONOMIC BENEFIT.
According to data from IDAE (Institute for the Diversification of Energy Saving), the electricity bill represents about $3,000 per year per address. With the use of suitable sustainable and ecological materials, the user would not pay more than € 300 per year. ” The cheapest and most efficient energy, and at the same time the least polluting, is that which is not needed, ” advises Miguel Ángel Gallardo, from Rockwool. Energy efficiency saves on bills month after month.
