Renewable energies are considered the future of energies and, in fact, are already very present today. Every day it is more urgent to bet on green, ecological or environmental energies with the environment that allow us to reduce the impact of climate change, which we have accelerated through our activities, among which the extraction and use of non -renewable energies stand out.
Therefore, and to generate greater awareness about the need to bet on sustainability, in this article in Ecology Verde, made in collaboration with Tech, we tell you everything about the renewable energies, its advantages and disadvantages. Tech is a digital university that offers us a variety of courses, masters, postgraduate and specializations, including university renewable energy courses. If you are interested in training in this interesting topic of renewable energies, do not hesitate to know these courses and continue reading this summary.
What are renewable energies
The energies are classified into two large groups: renewable energy and non -renewable energy. The first, Renewable energiesSometimes they are also called clean energies, that is, those that have their origin in Clean, inexhaustible resources and that are generated naturally, such as Hydraulic energy, solar or windand that, generally, during the process they can contaminate less than those obtained from non -renewable resources.
While the latter, Non -renewable energiesare conventional energies and although they also come from nature, come from limited natural resources And its extraction is increasingly complicated, such as fossil fuels (oil, coal or gas) or nuclear.
In summary, we can say that renewable energies are those that are obtained from the use of inexhaustible natural resources, such as sun, wind or water. If you want to expand this information, we recommend you read these other articles about what renewable energies and examples are and about the differences between renewable and non -renewable energies with examples.
Advantages of renewable energy
Now that you know what renewable energies are, it’s time to talk about the advantages of using them.
They respect the environment more
The main benefit of betting on renewable energies is, without a doubt, that most of them when used do not produce CO2 emissions or other harmful gases, that is, of gases that produce a greater greenhouse effect or polluting emissions for the atmosphere, as it occurs with fossil fuels. Thanks to renewable energies, the environment is more cared for, because they are more sustainable and reduce pollution that can have consequences both in our environment and our own health.
They are unlimited energies
If renewable energies are characterized by something, it is precisely because of that: because they are renewable and unlimited, that is, in principle They are not exhausted. We can always resort to them to continue producing energy without fear that their natural resources are over, as with fossil fuels, for example.
They are safer
Renewable energies, in addition to being environmentally friendly, are generally also much safer, since they do not generate waste during their exploitation and do not generate pollutant emissions harmful to health.
Facilitate autonomy
We talk about economic independence and even self -consumption. With renewable energies, foreign dependence decreases because production based on the natural resources of the area can Promote the economy of each region. In this way, not only the country’s resources are used, but you can also develop their own technologies and even be able to manufacture energy from our own homes, for example, through the installation of solar panels.
They create jobs
Renewable energies can generate many more jobs than conventional energies. Taking into account the projection of the demand and the implementation of this type of energies that must be happening in the medium term, it is estimated that these energies can generate up to five times more jobs than non -renewable.
Disadvantages of renewable energy
Without a doubt, renewable energies have more advantages than disadvantages, however, there are some inconveniences to take into account.
A part of them does contaminate
As is known, there is nothing that does not contaminate at all, since everything has a result when created, when used or destroyed that entails the production of gases or other elements. Therefore, it is true that renewable energies also contaminate, specifically and as an example, we can say that it contaminates the construction of the facilities to produce these energies from renewable natural resources. However, it is much lower pollution than that produced in general by non -renewable energies.
Obtaining energy is irregular
Since obtaining renewable energies depends 100% of the inexhaustible or renewable natural elements, When optimal conditions are not given. It all depends on atmospheric phenomena and these are not controllable. For example, in the case of wind energy the wind is needed to produce energy or, in the case of solar energy it is needed to be a fairly sunny area, which cannot always occur. In this sense there are energy storage means that seek to save large amounts of energy to supply the network when environmental conditions are not the most appropriate.
Resources are not the same according to the geographical area
One of the big problems of renewable energies is that Not all regions have equal natural resourcesso not everyone has access to the same amount or the same type of energy. It is a development and long -distance field that will need adaptations that allow anyone to have access to them.
Require investment and space
Renewable energies face great challenges, such as the installation of solar panels or energy storage and the tendency to carry out sustainable habits, such as the use of the electric car. Generating environmental awareness is basic to be able to bet on this type of energies, but it also requires an important investment that not all users, a priori, can be allowed. While this type of energies are profitable in the long run, at first they require remarkable economic disbursement, in addition to needing a large space that can negatively affect visual impact.
