Types of renewable and non-renewable energies

Energy sources are a series of resources that exist in nature and which have learned to be human to use to make life easier, depending on the one chosen will have a different durability in the weather. In this lesson from a TEACHER we bring you the types of renewable and non-renewable energies, with which you will learn how they are produced and which ones can replace those that are normally used. So we will have to know from the beginning that the so-called Non-renewableThey are those energies taken from resources from nature that are limited. While the renewable They are taken from elements of nature that regenerate and therefore never end.

Within our lesson on types of renewable and non-renewable energiesWe will first stop at non-renewable energies, which are the ones commonly used on our planet today.

Thus we will have to divide them into two large groups: fossil fuels (such as coal, natural gas and oil) or nuclear energy (in which we find nuclear fusion or fission). Next, we will break down each of the two mentioned:

Fossil fuels

These are formed by the accumulation of large amounts of remains of living beings, which remain enclosed in lakes or sedimentary basins and it is from these places that they are subsequently extracted. Within this group is:

• Coal: it is a black substance that comes from the fossilization of organic plant remains, there are four types: coal, peat, lignite and anthracite. Formerly it was a widely used energy as was the case of steam engines on trains or ships, although today it is It is used in thermal power plants, in some industries and there are even traces in some domestic heating systems (especially in peoples).
• Petroleum: it comes from the decomposition of the remains of microscopic organisms, being a liquid substance that has a density lower than that of water. It is currently used for the creation of gasoline, diesel, fertilizers, explosives, plastics, colorants, medications... Due to its great versatility it is very necessary today and therefore it is necessary to control its Bookings.
• Natural gas: it is usually found together with oil in the same bags, as it is a reaction of the particles that are in the liquid mass. Its main component is methane. When this energy was discovered, it was soon used to replace coal, because it was easier to transport and produced more energy, as well as being less polluting with the environment.

The nuclear energy

They are energies that are used in industry, above all, to heat water, move generators, produce electricity that later reaches our homes…. These come from the reaction of the atoms that materials have, such as uranium. They are very dangerous energies to use, as a simple failure can cause very dangerous radiation for living beings in general.

Next, in this lesson on renewable and non-renewable energy types, it is the turn of the renewable energies, which are currently being investigated to compete with those explained above, They are much less polluting with the environment, in addition to being unlimited. Within these we can find several groups such as:

Tidal energy (produced by the tides)

This is generated when the movements of the waters due to the rise and fall of these, although energy can also be drawn from the waves. Therefore, the turbines that are responsible for the production of this type of energy have to be introduced in places where the tides and waves are intense to obtain benefits quickly.

Hydraulic energy (generated in the reservoirs)

As a rule, the power plants located in the reservoirs introduce a series of turbines precisely by the place where the water precipitates when it is expelled at the moment the reservoir is reaching a high point of its ability. When the water is expelled it falls, thereby driving the turbines, which generate a large amount of kinetic energy.

Geothermal energy (produced by the heat of the earth)

We will usually find it related to hot springs or with the places where we find magma. Currently it is an energy that is in the process of investigation, due to the difficulty of finding places conducive to this (in this way it is quite expensive energy and does not leave many benefits to day of today). Even so, the use of its electrical source for heating homes, industrial uses, uses in agriculture and even to generate electricity is known.

Solar energy

It is one of the best known today and we relate it to the solar panels that we find today in many parts of the world, These convert the energy from the rays into clean energy that is later used with other purposes. It is one of the cleaner energies and that depending on the place (in our case it is exceptional) it produces a lot of energy, which can be used for heating both water and air.

Wind power

We can say that, together with solar energy, they are the two best known. Is is collected by the force of the wind, which moves the blades of the mills distributed throughout the geography. Inside they have a coil that, as it moves, generates energy that can be used for electricity as well as other uses.

Biomass energy

It is obtained by decomposition of organic compounds of living beings, whether they are plants or animals. From there elements such as alcohol, oil or even methanol can be produced; the problem is that it takes a lot of scraps to generate enough power. The studies at present are related to the well-known biogas, which wants to compete in the future with natural gas.

To end our lesson on the types of renewable and non-renewable energies, we must say that, although today the most used energies are non-renewable. A great deal of capital is being dedicated to the study of renewables, so we can already see how today they are beginning to bet on cars and motorcycles powered by electric motors.

The problem in many cases is that, in order to generate these energies, a large amount of capital, since they are much more expensive energies to produce in the beginning, because they need more machinery and control.

Even so, we should be aware that not everything we have on our planet is eternal If it is not taken care of, therefore we must abide by the laws towards the environment to leave a legacy to the next generations.
