With respect to renewable energy types and characteristics, there are several options and below we will know the most important ones.
Many experts agree that the future of humanity lies in renewable energy and that this type of energy is taken from sources that are practically indefinite and that also produce practically no environmental pollution.

Renewable energy types and characteristics
Hydraulic energy, also known as hydroelectric renewable energy, is one that takes advantage of the great force that water has in rivers and seas to convert that force into electrical energy.
In order to carry out this conversion, large facilities (usually dams) are necessary to help make the most of a renewable natural resource such as water.
Studies show that approximately 20% of electricity is currently produced worldwide with this type of renewable water energy.
While hydroelectric solar energy uses the water that runs through the seas as a renewable and inexhaustible resource, hydroelectric wind energy uses the wind to generate energy and electricity.
It is one of the cheapest forms of energy today and simply consists of taking advantage of the large wind currents that move the “propellers” or blades of a wind turbine, thus generating electricity with a process that is not polluting, that is low cost and that uses a resource that is clearly inexhaustible.
Geothermal renewable energy is one that takes advantage of the natural heat of the earth to generate electricity.
Usually the use of this type of energy is done in large installations that are commonly called district heating systems.
It is one of the least known energies, but among its great advantages we can find that it respects the environment, that it is very good for residential use and that it has a fairly low cost.
Biomass renewable energy is one in which some of the waste that human beings produce daily is used. It is truly excellent to take advantage of that waste that is wasted.
It is important to understand that this energy can be obtained from both animal and plant waste and that there are different types of biomass (natural, residual and produced).
It is also known as renewable energy bioenergy and is usually more used in remote places that do not have as much access to industrialization.
Renewable wave energy is also known as wave energy since it is the one obtained from the movement of the air in the sea, producing waves of great force.
Let us remember that the waves in the large oceans usually have a large amount of energy accumulated by the action of the strong winds that move them and that this energy can finally be converted into things of interest, such as electricity.
It is currently highly studied and there are thousands of scientists around the world looking for the possibility of taking advantage of much more of this energy and getting more out of it.
Clearly one of the great “obstacles” or complications that have been found is the possibility of storing that energy to be used later and it is a problem that will seek to be addressed in the future.
Although they are very similar, tidal renewable energy is different from wave energy. In this case, tidal power uses the tides (when the sea water rises) for the generation of energy, something totally different.
In any case, tidal power is much more similar to hydroelectricity in that dams and turbines are also used to take advantage of the force of the tide and generate energy.
It is quite regular and renewable, but the disadvantage is that it is usually a bit intermittent (the tides only occur in the morning and at the end of the afternoon) and can be somewhat expensive.
Solar renewable energy is one of the most widely used in the world and is becoming increasingly important thanks to its great advantages that make thousands and millions of people around the world disconnect from the electricity grid and become sustainable.
One of the great advantages of this energy is that it clearly uses a resource that is inexhaustible and that appears every morning without fail and lasts for a good number of hours so that it is possible to accumulate all the energy necessary to spend the nights without problems.
Regardless of the type of solar energy that is being used, the key elements to be able to take advantage of the energy are the solar panels, elements that can be of different types (solar, photovoltaic or external collectors).
There are different ways to take advantage of solar energy, two of the most recognized today are: photovoltaic renewable energy and thermal renewable energy, we will learn more about them below.
Photovoltaic Solar Energy
To generate this type of energy, you must have photovoltaic solar panels that are made up of cells that take energy from the sun and convert it into electric current.
After obtaining such electrical current (direct) it must go through a converter to finally obtain the alternating current that we use in our homes, businesses and more.
The capacity of this type of solar energy to generate autonomy in houses, homes, apartments and even factories and companies is really surprising.
Thermal solar energy
On the other hand we have solar thermal energy that is used primarily to heat water and that can be used for heating, for domestic uses or even to generate electricity by producing water vapor.
passive solar energy
Passive solar energy is also known, which simply consists of the good use of available resources and architecture to use solar radiation and, for example with the use of solar panels, heat a space in a home.
Possibly not all the types of renewable energy that exist today are mentioned above, we have simply commented on some of the most important types and characteristics of renewable energy so that you know a little more about the ways of generating energy that could change the world.
