Non-renewable energy examples
Renewable Energy is the energy obtained from natural sources that are virtually inexhaustible, either because of the immense amount of energy they contain or because they are capable of regenerating themselves by natural means.
The use of renewable energy sources by man is very old. Since many centuries before our era, renewable energies such as solar, wind and water were used by man in his domestic, agricultural, craft and commercial activities. This situation prevailed until the advent of the First Industrial Revolution in the 18th century, when renewable energies had to give way to fossil resources such as oil and coal, which at that time were offered as abundant and cheap sources of energy. The industrial revolution also triggered the social and economic changes that led to the subsequent development of the large hydroelectric industry, now considered a conventional renewable energy source.
Nowadays, when the availability of fossil resources plays a determining role in the global and national energy supply, and when environmental factors appear among the main concerns of contemporary society, Renewable Energies are re-emerging with increasing success in all latitudes of the planet, encouraged by the constraints of energy supply and the presence of favorable regulatory frameworks.
Non-renewable energy oil
There are two types of non-renewable energy, conventional and non-conventional. Conventional non-renewable energies include all fossil fuels, such as oil, natural gas and coal, which are frequently and widely used energy sources in the world.
These types of sources have a regular distribution all over the planet and produce a large amount of energy per unit of time, without forgetting that they have been the great protagonists of the industrial impulse since the invention of the steam engine.
The environmental problems caused by this type of energy sources, such as the greenhouse effect, rising temperatures and other consequences, are well known. That is why we are working every day to stop using this type of energy sources and replace them with renewable energies.
As non-renewable and non-conventional energy sources, we can find those that come from biofuels, agrofuels or cultivated fuels and nuclear fuels such as uranium and plutonium.
Harnessing non-renewable energy sources
Hydraulic, wind, solar, biomass and geothermal energy are clean and inexhaustible energies. As renewable energies, they play a predominant role in the energy transition. It is therefore essential to promote their development to combat climate change.
An energy is said to be renewable when its energy source is based on the use of natural resources, such as the sun, wind, water or biomass. Renewable energy is characterized by the fact that it does not use fossil fuels, but natural resources capable of unlimited renewal.
In addition to being inexhaustible energies, they do not produce greenhouse gases (GHG), the main cause of climate change, or pollutant emissions, so they have a very low environmental impact. It can be said that renewable energies are clean energy sources.
Why is nuclear energy not renewable? Nuclear energy is a decarbonized and non-polluting energy. It does not emit greenhouse gases into the atmosphere. However, uranium, the fuel used in nuclear reactors, is a limited resource. Therefore, nuclear energy is a clean but non-renewable energy.
Classification of renewable and non-renewable energy sources
We define non-renewable energy as energy resources that tend to run out. The rate of consumption of these resources is greater than the rate of their regeneration. Non-renewable energies are methods of producing energy from an exhaustible energy source.
Geothermal energy is generally considered a renewable energy. However, there is a specific type of geothermal energy that uses hot water. Depending on the regenerative capacity of these thermal sources, geothermal energy can be a non-renewable energy.
