Currently, renewable energies are gaining importance within the energy models of different countries and, in fact, more and more countries are producing their energy from natural sources. An exemplary case is Costa Rica, which bases practically all of its electrical matrix on renewable energies.
To vindicate this type of energy, we will dedicate this post by Green Ecologist to talk about What are renewable energies. If you want to learn everything about this topic, we encourage you to continue reading and learn from what these energies are to their importance, several examples, their advantages and disadvantages and their differences with non-renewable energies.
Let's start this section by defining what renewable energy is. These are defined as the energy obtained from renewable or inexhaustible sources. The fact that they are inexhaustible is due to the fact that they exist in immense quantities or because they have the ability to regenerate through natural processes at a higher rate than they are consumed.
Its main peculiarity is that its obtaining and subsequent use does not generate serious polluting products or emit greenhouse gases that contribute to climate change. Therefore, many refer to renewable energies as clean or green energies, since they are friendly to the environment. It does not mean that they are innocuous, everything has its impact on the environment, but it is much less and different from that of energies that are not renewable.
So why is renewable energy important? As we mentioned before, renewable energies themselves do not emit greenhouse gases into the atmosphere, therefore they are carbon neutral and do not contribute to climate change. Taking into account that we are going through an unprecedented climate crisis and that one of the causes that triggered this crisis is the exploitation of fossil fuels for power generation, renewable energies are the environmentally friendly replacement for fossil fuels. For this reason, renewable energies are of enormous importance worldwide when drawing up energy plans. climate change mitigation. Undoubtedly, renewable energies are and will be fundamental in the sustainable development models that countries must design to combat climate change.
Fortunately, depending on the characteristics of each site, there are several types of renewable energy. Here we will give some examples:
In the case of nuclear energy, also called nuclear fission, we want to mention it separately because it tends to cause confusion. It is the one that is released as a result of a reaction where heavy atomic nuclei are divided, in general uranium is used. A) Yes, nuclear energy is not a renewable energy, since the presence of uranium on Earth is finite and does not get to regenerate in the quantities that are required. However, it is considered a clean energy, since its obtaining does not emit greenhouse gases into the atmosphere, that is, it does not emit polluting gases in the process of obtaining and using it (although this is not the case when it is necessary to build the facilities and other aspects). On the other hand, if the waste it can generate is polluting.
If you want to know more about these examples, here you will find information about renewable energies: which are the most important?
Next, we will mention the advantages and disadvantages of renewable energies in order to know them a little better:
You can learn more by reading this other post about the Advantages and Disadvantages of renewable energy.
When we talk about renewable energies, it is impossible not to name those that are not renewable. That is why, to clarify concepts, here we will talk about their differences.
Learn more about their differences by reading this other article on renewable energies and non-renewable energies: examples and differences and with the video that you will see below. In addition, we recommend you read about the state of renewable energies in Spain.
