10 Examples of Renewable and Non-renewable Energies

Obtaining Energy It is a process that is fundamental for most of the activities that human beings carry out on earth and also for the goods that it has produced for consumption and production. For example: electric power, wind power, hydro power.

The human body itself is capable of producing energy for the activities it performs, but not for the operation of the equipment and machinery that have been built throughout the extensive process of the civilization.

The Energy sources are the sum of the existing resources in nature, from which people can obtain energy to run various equipment and machinery, and are fundamentally divided into two groups: renewable and non-renewable.

Examples of non-renewable energies

The non-renewable energy or conventional is that obtained from limited natural resources, which once consumed in their entirety do not offer the possibility of being substituted. There are a number of reserves in the world for this form of energy production, but nothing beyond that.

It is usual that the means to produce energy is the burning of

fossil fuels, which releases large amounts of greenhouse gases that contribute to the global warming.

Some examples of non-renewable energies are:

1. Natural gas. It is a fuel of fossil origin, which consists of a mixture of hydrocarbons light compounds mainly of methane, nitrogen, carbon dioxide and ethane. It is located in the subsoil or under the sea, and must go through a double transformation from its extraction to its possibility of effective use.
2. Petroleum. Organic compound present in different deposits, whose formation takes hundreds of millions of years. After extraction, it must be separated from gas and water through a process known as refining.
3. Coal. Mineral of organic origin, consisting mainly of carbon. Its formation also takes millions of years and its energy use is carried out in thermal power plants or thermoelectric plants to generate electricity: its steam can reach a temperature close to 600 ºC.
4. Nuclear fuels. Materials that through fission or fusion release different types of energy, usually thermal. The technology using these sources of energy is called nuclear technology. The main nuclear fuels are uranium and plutonium.

Examples of renewable energies

The renewable energy It is one that is obtained from potentially inexhaustible natural sources, due to the amount of energy they contain or because they are capable of regeneration through the natural environment itself. It is not an unlimited source, so its use must be subject to the timing of the renewal.

Energies of this type began to be considered as alternatives to conventional ones around the 70s and their developments were fundamentally motivated by economic necessity, although for now conventional energies are still generally more cheap.

It is also common for renewable energy to need a very large space to be able to develop, which is not always guaranteed.

Some examples of renewable energy:

1. Biomass energy. Energy is obtained from the dry weight of organisms, after having completely extracted the water that is in them.
2. Solar energy. The projections of the energy flow released by the sun are used to transform them into energy.
3. Wind power. By means of the wind, it is possible to move different devices, usually wind turbines.
4. Seawater energy. They take advantage of the differences in the average height of the seas according to the position of the Earth and the Moon, and with this electricity is generated. It is the energy obtained from the tides.
5. Geothermal energy. The energy comes from thermal phenomena inside the earth's crust.
