Currently technology is present at all times in our lives, to the point that we have become dependent on it and the great demand for electricity makes its costs increase. 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 in 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 knowing what the energy certificate is, continues to read this interesting ecology article in which we explain What is energy efficiency and examples of this.
What is energy efficiency
As a simple definition of what is the Energy efficiencywe can say that this consists of using equipment or facilities that They consume less energy To achieve the same performance or perform the same function, such as, for example, by providing a product or service.
In this way, energy is used much better, it is not waste or more resources are used to produce much more than it really is necessary.
What is the energy certificate
The energy certificate is a document in which the Effectiveness of a building with respect to energy consumption. This document includes data such as energy management and CO2 emissions, among others. The energy certificate is carried out with different objectives: reduce energy consumption and make the home owner or promoter know their energy consumption.
As for the Energy efficiency labelingdepending on the energy consumption of a building or product to this can be included the energy efficiency labeling to give information to the consumer.
In these labels a scale will be displayed that evaluates the Energy efficiency A, B, C, D, E, Fygthat is, it indicates them with letters, being “a” the most efficient and “g” the least efficient. Although this is the scale, really after the letter A there are three others. Do you know what energy efficiency means to+, A ++ and A ++? These three categories are those, depending on the amount of +, they save from 10% and 45% of the average.
Energy efficiency: examples
There are many actions or changes in our daily lives that can be made to be more efficient with the use of energy. These are some Energy efficiency examples In our day to day:
- Insulation of buildings thus reducing the need to use air conditioning systems.
- Change the light bulbs or lamps from the houses for LED lamps that are more durable and emit the mimas amount of light.
- The use of small lamps consumes less than the general lights, for example, when we see TV or read a book it is more convenient to turn on a small lamp.
- Do not leave electrical equipment such as televisions, loaders, DVD players, among other, connected. The fact that these are turned 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 bulbs. This type of architecture uses the bioclimatic energy of light and heat that comes from the sun.
- When we have the heating put that this does not exceed 20 ºC, as with the air conditioning that is not less than 26 ºC.
- When buying 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 greater price, but in the long term not only are energy saving, but also economic.
Energy efficiency: advantages and disadvantages
As with everything, we can also analyze the advantages and inconveniences of energy efficiency.
Advantages of energy efficiency
The advantages 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 with the outside.
- Expenses are reduced at a residential level and in tertiary sectors.
- Reduction in the emission of greenhouse gases.
Disadvantages of energy efficiency
- The efficient alternatives are more expensive, although in the long term it is profitable for the savings that it will mean, sometimes it is preferred to pay less at the time of purchase.
- It is a choice, that is, there are no laws that establish as mandatory the production of efficient products or the use of more efficient facilities in industries.
What is the importance of energy efficiency
The fact that they are important Efficiency and energy savings It is due to the fact that the consumption of energy worldwide grows excessively and, in addition, the Great energy dependence makes the cost of this increase.
In addition, the use of conventional energies, the most used, contributes to the acceleration of climate change since non -renewable natural resources are being exploited to produce it and greenhouse gases are emitted to the atmosphere.
