Context
There are several ways to produce energy, from the oldest and most traditional, such as energy from burning coal or oil, to the most modern and sustainable, such as solar and wind energy. Energy sources can be classified into two main groups: non-renewable and renewable. Non-renewable energies are those that have been accumulated in nature over millions of years, such as oil and coal. On the other hand, renewable energies, the central theme of this project, are those that have the capacity to renew themselves, meaning they do not deplete.
Renewable energies present significant advantages over non-renewable ones, such as reducing the emission of polluting gases, diversifying the energy matrix, and promoting energy independence. Furthermore, renewable energy is a viable alternative to meet the growing demand for energy and combat climate change. To better understand how renewable energies work, it is necessary to understand the concepts of energy, energy sources, energy matrix, and sustainability.
Energy is a physical quantity that associates the capacity to perform work. In other words, energy is the ability to produce movement or action. Energy sources are the natural or artificial resources used to produce energy. The energy matrix is a set of energy sources that a country or region has and uses to produce energy. Sustainability is a concept that involves the balance between economic development, the environment, and social well-being.
In this project, you will learn about the main renewable energy sources, such as solar, wind, hydroelectric, tidal, and biogas energy. The proposed practical activity will help you better understand these concepts and the importance of renewable energies for our planet.
The energy issue is one of the great challenges of the 21st century. The intensive use of non-renewable energy sources has resulted in numerous problems, such as pollution, deforestation, and intensification of the greenhouse effect. However, renewable energies are a viable and sustainable alternative to minimize these problems. They are clean energy sources that do not emit polluting gases and do not contribute to global warming. Furthermore, they are inexhaustible energy sources that can be harnessed worldwide, contributing to the diversification of the energy matrix and energy independence.
