We explain what clean energies are, why they are important and what they are. In addition, examples and what are polluting energies.
It is known as clean energy or green energy to those forms of obtaining energy that produce a minimum or no ecological impact on the environment , during its extraction and generation processes. That is, it is ecological or eco-friendly energies.
In real terms there is not yet a way to obtain usable energy that is absolutely harmless in environmental terms. However, some pollute much more than others and leave an indelible mark of their presence in the ecosystem and in the health of living beings . Those that seem to be safer and more reliable in ecological terms , are the ones we consider as clean.
Clean energy should not be confused with renewable or sustainable energy . By the latter it is meant those that do not deplete the raw material of your process , or they do so slowly that you give room for nature to replenish them . Some of these renewable energies may be clean, but others are not.
In particular, clean energies often use the force and heat of natural elements , channeling them to generate usable electricity in homes and human industries. And they do so causing the least possible impact on their respective ecosystems, which does not mean that they do not have any kind of impact or negative consequences.
In view of the climatic changes and global warming that have been brewing since the beginning of the Industrial Revolution (17th century), there is an urgent need for an efficient, but sustainable energy system that does not end with the planet in the process.
Our world every day requires more and more energy, but fossil fuels and nuclear energy represent a threat rather than a solution , given its consequences on human health and the world’s climate balance. That’s when clean energies become tremendously necessary.
Strictly speaking, clean energies would be as follows:
Some examples of these energies are:
The polluting energies are those that are obtained at the cost of causing considerable environmental damage , whose consequences can be devastating for human and animal life, as well as for the planet’s climate balance. These include nuclear energy and the burning of fossil fuels (coal, oil ).
