What exactly is renewable energy?

Clean and renewable energy

The Earth has limited resources.  And it is in our hands to do our bit every day so that both our generation and that of our sons and daughters can enjoy the valuable natural resources.

Have you ever thought that taking care of the environment doesn’t just mean recycling at home or reducing energy consumption? It also means using green energy – find out what it is and how to use it!

If you are concerned about the deterioration of the environment in which you live, it’s time to learn about the existence of green energy. It is likely that you have heard the term green energy and do not know exactly what it is. We clarify it for you!

Green energy is the one that comes from non-polluting and environmentally friendly natural energy sources such as, for example, wind, water or sun. In this sense, wind, tidal or solar energy stand out. Those do sound familiar, don’t they?

First of all, you should know that it is possible for a house to be self-sufficient from the energy point of view, in such a way that it is self-sufficient without the need to consume external energy. How? Very simply, by combining several renewable energy sources.

Many people believe that renewable energies and clean energies are exactly the same, but both types have their own qualities and characteristics that differentiate them from each other. Do you want to know what they are? Read on! Atlas Energia explains it to you.

Renewable energies base their production and origin in a natural source, such as wind (wind energy) or sunlight (solar energy). The source of these energies is also characterized by being inexhaustible, hence they are considered renewable.

In fact, their own production process renews and regenerates them, since their main source is inexhaustible. For example, solar energy is renewable because sunlight is in constant action and renewal.

Despite the positive points of renewable energies, not all types can be considered non-polluting, environmentally friendly or clean. In particular, the renewable that does pollute is biomass energy.

The renewable energies that do pollute involve a problem similar to those produced with fossil fuels. That is, their consumption generates a quantity of carbon dioxide that is too high for the stability of the environment.

Do you know the advantages and disadvantages of renewable energies? Betting on them is a great decision with short and medium term benefits for the protection of the environment that we want you to know, but it is also important to know their cons.

Therefore, if you are wondering what renewable energies are, you will like to know what they are and the pros of wind, hydro or solar energy, among others that you can learn about in this article on the different types of energy.

Despite this definition of renewable energy it is easy to have problems to know what is renewable energy and what is not renewable. Therefore, we want to make clear the main characteristics of these before dissecting the advantages and disadvantages of renewable energies.

Non-renewable energy: conventional energies are those obtained from fossil fuels, such as oil and nuclear fuels. They are limited and emit polluting gases into the atmosphere.

There are many pros of green energies and we want you to know at least the most important ones. In this way, you will understand even more the importance of betting on them and you will be able to share it with your friends and family.

Non-renewable energy

Solar energy, as its name indicates, is the energy generated by the sun and which travels to the Earth through radiation. Its importance is unquestionable, since it is a renewable energy source, therefore, it is a real alternative to other energy sources that are being depleted. Another of its main characteristics is the efficiency in its use and exploitation, since it does not contribute to the deterioration of the environment, as is the case with oil, for example.

As mentioned above, the sun is responsible for heating the Earth via solar radiation. Radiation travels from the sun through space by means of particles called photons. These particles are what transport solar energy. The success of this renewable source lies in the fact that the energy the Earth receives is 5,000 times greater than the energy it consumes, which is why it is characterized as unlimited.

First of all, photovoltaic solar energy. This is the direct transformation of sunlight into electricity. It is achieved thanks to the transformation of photons into electricity by means of photovoltaic solar panels installed in fields, rooftops and terraces, among other areas.
