Types of renewable energies

Types of renewable energies

We say that an energy is renewable when it comes from a natural source and does not run out over time. In addition, it is clean, does not pollute and its resources are very varied. There is a wide variety of renewable energies on our planet and, as technology advances, more ways are discovered to harness the energy of our planet without having to resort to Fossil fuels and continue with the effects of climate change.

In this post we are going to show you all the types of renewable energy that exist so that you can see and analyze the capacity we have to generate green energy without damaging our planet and promoting quality employment. Do you want to know what are the types of renewable energy? Keep reading.

Biofuels

biofuels

Starting with transport, we must mention that it is a sector of society that consumes a large amount of fuel and, therefore, pollutes the atmosphere. To avoid excess pollution, rising oil prices and oil depletion, biofuels were developed.

These are liquid or gaseous fuels that are produced from biological plant or animal raw materials. It is a renewable energy source that does not run out and can meet the demand in transport. Thanks to the use of these green fuels, our dependence on oil can be reduced and the environmental damage it produces can be reduced.

Among the most important biofuels we find biodiesel and bioethanol. The first is obtained from fresh vegetable oils and the second from raw materials rich in sugar or starch such as sugar cane.

Biomass energy

biomass energy

Another type of renewable energy is biomass. It is the organic matter that is used to generate energy. It collects a set of organic matter that is characterized by having heterogeneity and different origins. Biomass can be considered as organic matter that is generated in biological processes and that can be used as a source of energy.

For example, we find agricultural and forestry remains, sewage, sewage sludge and the organic fraction of urban solid waste. There are different processes by which to take advantage of biomass energy. Heat and electricity can be harnessed and generated by combustion, anaerobic digestion, gasification and pyrolysis.

Energía eólica

wind power

Basically this type of energy is based on collecting the Kinetic energy It has a mass of air and generate electricity from it. It has been an energy used since ancient times by man to power ships with sails, mills to grind grains or to pump water.

Today today they are used wind turbines for generate electricity from the wind. Depending on the force with which you blow you can obtain more or less quantity. There are two types of wind energy, marine and terrestrial.

Geothermal Energy

geothermal energy

It's about the energy that is found stored as heat under the surface of the earth. And it is that our planet is full of energy that we can take advantage of to generate electricity. It is a production that is active 24 hours a day, so it is inexhaustible and does not pollute at all.

Geothermal energy It has two types: high and low enthalpy.

Marine energy

marine energy

This type of energy does not have a single way to extract itself. It happens as with solar energy. It is a set of technologies capable of harnessing the energy of the oceans. Depending on the weather at all times, the force of the oceans can be unstoppable, but also very good to take advantage of energy.

Waves, tides, currents and temperature differences between the surface of the seabed they can be used as a source of energy. In addition, it has the advantage that it does not generate environmental or visual impacts that we have to take into account. Although it is not an energy that provides great strength in the energy mix of the countries, it does serve as a good and considerable reinforcement.

Small wind energy

mini wind energy

The operation is the same as wind energy, except that it is intended to harness the wind with wind turbines with a power less than 100 kW. The sweeping area of ​​the blades cannot exceed 200 square meters.

This type of renewable has some advantages such as supplying electricity to more isolated areas that are far from the electricity grid. In this way we can enhance self-consumption and avoid losses in the transport and distribution of fossil energy.

Hydraulic energy

hydraulic energy

Hydraulic power It is one that takes advantage of the kinetic energy that a body of water has. Thanks to the waterfalls caused by the difference in level, the force of the water can move a turbine that generates electricity. It should be mentioned that this type of renewable energy was the main source of large-scale electricity production until the middle of the XNUMXth century.

They work thanks to a hydraulic power station and it is recognized as the most environmentally friendly energy of all.

Solar energy

It is about taking advantage of solar radiation to generate electricity. There are three types of solar energy.

Photovoltaic Solar Energy

photovoltaic solar energy

It is the direct transformation of incident solar radiation into electricity through the use of solar panels. Thanks to photovoltaic cells, the solar radiation that falls on them can excite electrons and create a potential difference. The more solar panels you have connected, the greater the difference in potential.

Solar thermal

solar thermal energy

It is a variety of solar energy that is responsible for supplying the thermal demands in buildings, industry and the agricultural sector. It is a fairly efficient way to harness the energy of the sun.

Thermoelectric solar energy

thermoelectric solar energy

This type of energy uses lenses or mirrors capable of concentrating solar radiation on a smaller surface. This is how they are capable of obtaining higher temperatures and, therefore, converting heat into electricity through a fluid.

These are all the types of renewable energy that exist. I hope you can get to know them better.
