Definition of renewable energy

Natural Resources

Man lives within a diverse natural environment surrounding him, with which he exchanges influences and influences, and this environment is characterized by its richness and the many wealth that God created, whether these riches are above the earth or in its interior in what is known as natural resources, such as sun, wind, water, etc., and man has tried all the time to exploit them with his mind and intelligence. Especially since this type of energy does not need highly complex or costly technologies in terms of operation and use, and these resources are among the most important basics of production processes in some countries, and the resources are of two types; The aforementioned natural and human resources that are based on the existence and energies of man and workers, i.e. the human element is its foundation.

sustainable energy

Renewable energy is an inexhaustible natural wealth that does not result in substances harmful to the environment, creatures, or humans after its use. It remains in a continuous state of existence and renewal, and it does not come to a time when it will run out. It is converted from one form to another before it is ready for use, and it does not cause any harm. A kind of inconvenience when used, and it is known by other names as clean energy and it is environmentally friendly, and it saves people the costs of obtaining other types of energy that they use in different areas of their lives, while other types of energy cause exhausts and toxic and harmful gases to humans.

Man uses and adapts the resources of his environment in order to benefit from them in his life. The wind generates electrical energy that drives giant generators, and thus benefits from electricity at the lowest costs and in the optimal way, through the presence of fans and windmills in vast fields, and solar energy is used to heat water in solar heaters on rooftops. Water for bathing, cleaning, washing and cooking purposes, and is also used to generate electricity through powerful waterfalls.

However, at the present time, some environmental phenomena negatively affect them. Such as the phenomenon of global warming, pollution, industrial waste, etc. Therefore, the users of these energies and resources must have sufficient awareness and culture that makes them realize their benefits, and not engage in wrong behaviors that destroy or harm them.

It should be noted that the concept of renewable energy is matched by the concept of non-renewable energy that will expire after a certain period of time, and scientists remain in a state of continuous appreciation for its length, such as petroleum or oil, which is present in the form of wells in the ground, and various petrochemical industries are made from it, and it is converted into Gasoline, diesel and other fuels that are used in the transport and communication sector, in addition to natural gas that is used for cooking gas uses, and many other types.
