Energy is not created from nothing, and it is always transformed from one form to another according to the laws of energy and conservation. For example, in electric power plants, energy from various sources is converted into electrical energy.

Energy can be renewable, such as solar or wind energy, and it can also be non-renewable, such as coal or oil energy. This transformation between different forms of energy occurs when using a specific technology that depends on the type of source and the technology used to transform it.

We derive electrical energy from a variety of sources, ranging from traditional generation plants such as steam, gas or nuclear plants, to renewable generation plants such as wind mills and solar cells.

In addition, electrical energy can be stored in batteries in the form of chemical energy, which is converted into direct current electrical energy when needed.

Since energy sources are of great importance in meeting our daily needs in various fields, humanity cannot currently do without them. Global efforts are currently moving towards keeping pace with and adopting renewable energy sources, by trying to make them a sustainable alternative to traditional sources.

Energy sources: between conventional, renewable and nuclear

Energy sources are the cornerstone of meeting the needs of daily life and supporting economic progress and sustainable development. Energy sources can be divided into three main categories: conventional, renewable, and nuclear.

Traditional sources:

These include traditional sources such as fossil fuels, which are extracted from the remains of living organisms that have been buried in the ground for thousands of years. Fossil fuels consist of coal, oil and natural gas, and are used in power plants to generate thermal energy that is later converted into electrical energy.

Renewable sources:

Renewable sources include solar energy, wind energy, bioenergy, and geothermal energy. These sources rely on the use of solar energy as the primary source, and are considered environmentally friendly and sustainable in the long term.

Nuclear Energy:

Nuclear energy is a unique resource, as it arises from nuclear reactions. Energy is generated through the fission of nuclear atoms, converting them into thermal energy that can be used to generate electricity. Although it is not entirely renewable, it is an important alternative.

In conclusion, these sources come with different challenges and benefits, and achieving a balance between relying on sustainable sources and taking advantage of traditional sources with an environmental impact represents an ongoing challenge for the global energy future.
