Currently technology is present at all times in our lives, to the point that we have become dependent on it and the high demand for electricity increases its costs. In addition, its generation is bringing consequences to the environment with the overexploitation of natural resources and greenhouse gas emissions. To avoid these impacts of technology on the environment, it is important to bet on energy efficiency.

If you want to know more about energy efficiency, its advantages and disadvantages, as well as what the energy certificate is, continue reading this interesting article by Green Ecologist in which we explain what is energy efficiency and examples this.

What is energy efficiency

As a simple definition of what is energy efficiency, we can say that this consists of using equipment or facilities that consume less energy to achieve the same performance or perform the same function, such as when providing a product or service.

In this way, energy is used much better, no more resources are wasted or used to produce much more than is really necessary.

What is the energy certificate

The energy certificate is a document in which the efficiency of a building with regard to energy consumption. This document collects data such as energy management and CO2 emissions, among others. The energy certificate is carried out with different objectives: to reduce energy consumption and make the owner or promoter of the house know its energy consumption.

Regarding the energy efficiency labelingDepending on the energy consumption of a building or product, it may include energy efficiency labeling to provide information to the consumer.

These labels will show a scale that evaluates the energy efficiency a, b, c, d, e, f and gIn other words, it indicates them with letters, "a" being the most efficient and "g" the least efficient. Although this is the scale, really after the letter A there are three more. Do you know what energy efficiency A +, A ++ and A ++ mean? These three categories are those, depending on the amount of +, they save from 10% to 45% of the average.

Energy efficiency: examples

There are many actions or changes in our daily lives that can be carried out to be more efficient with the use of energy. These are some examples of energy efficiency in our day to day:

  • Building insulation thus reducing the need for the use of air conditioning systems.
  • Change the bulbs or lamps of the houses for LED lamps that are more durable and emit the same amount of light.
  • The use of small lamps consumes less than general lights, for example, when we watch TV or read a book it is more convenient to light a small lamp.
  • Do not leave electrical equipment such as televisions, chargers, DVD players, among others, connected. The fact that these are off, continues to consume since it is in Stand By mode.
  • Take advantage of the sun, for example, avoid the use of electric dryers and dry our clothes in the sun. Or also, design houses with large windows to illuminate the houses, thus avoiding lighting light bulbs. This type of architecture uses the bioclimatic energy of light and heat that comes from the Sun. Here you can see more about the Advantages and disadvantages of bioclimatic homes.
  • When we have the heating on that it is not higher than 20 ºC, as with the air conditioning that it is not less than 26 ºC.
  • When buying electrical appliances, it is advisable to look at the energy efficiency label, which indicates the efficiency of the product. With the label we can know which are those that have low consumption or even those that allow you to save. These appliances have a higher price, but in the long term they are not only energy saving, but also economical.

Energy efficiency: advantages and disadvantages

As with everything, we can also analyze the advantages and disadvantages of energy efficiency.

Advantages of energy efficiency

The benefits of energy efficiency interfere with both the natural environment and society.

  • Reduction of environmental pollution and the use of natural resources.
  • The production costs of companies decrease, being able to be more competitive.
  • Decrease in energy dependence on the outside.
  • Expenses are reduced at the residential level and in tertiary sectors.
  • Reduction in the emission of greenhouse gases.

Disadvantages of energy efficiency

  • Efficient alternatives are more expensive, although in the long term it is profitable for the savings it will entail, sometimes it is preferred to pay less at the time of purchase.
  • It is a choice, that is, there are no laws that make the production of efficient products or the use of more efficient facilities in industries mandatory.

What is the importance of energy efficiency

The fact that they are important efficiency and energy saving It is due to the fact that the consumption of energy worldwide is growing in a disproportionate way and, in addition, the high energy dependence causes the cost of this to increase.

In addition, the use of conventional energies, the most widely used, contributes to the acceleration of climate change since non-renewable natural resources are being exploited to produce it and greenhouse gases are emitted into the atmosphere.
