Renewable energy sources
There are various types of renewable energy sources such as solar energy, wind energy, tidal energy, bioenergy, geothermal energy, hydroelectricity, and biofuels.

Awesome Facts about Renewable Energy and Types of Renewable Energy Sources

Energy is one of the forms of existence and an essential component of the universe. Energy is usually derived from both natural and non-natural sources, so it is divided into two main types: renewable energy, which is dependent on natural resources, and non-renewable energy which is dependent on non-natural sources, both of them are formed over time and under a combination of factors. All these types of energy require special mechanisms, tools, and techniques to be extracted and harnessed to give benefits to humans. In this article, we will highlight renewable energy and everything related to it.

What is Renewable energy?

Renewable energy is a type of energy that is inexhaustible and does not run out. It comes from natural resources such as wind, water, and the sun. The most important characteristic is that it is clean and environmentally friendly; as it does not leave harmful gases such as carbon dioxide, does not adversely affect the surrounding environment, nor does it play an influential role in the temperature level.
Renewable energy sources are completely incompatible with their non-renewable sources, such as natural gas and nuclear fuel. These sources lead to global warming and release carbon dioxide when used. Based on the importance of renewable energy, a new type of business has recently emerged under the name of "Renewable Energy Trading". Most of its work focused on harnessing renewable sources of energy and exploiting them as a source of income and material benefit by promoting them. Despite the high cost of using renewable energy, the lack of sufficient mechanisms and technologies. However, there are a large number of countries that are preparing to start investment projects for renewable energy, taking care to draw the dimensions of the project policies and work to develop these projects.

It protects crops from chemical contaminants, thus raising agricultural productivity.

Types of Renewable Energy Sources

Renewable energy comes from several sources and has different types and can be divided into several categories:

Solar energy:
Solar energy is defined as the light and heat coming from the sun. It is exploited by humans in their interests and harnessed by technological means and techniques. The sun can be harnessed to generate thermal and electrical power, either electric power.
Solar energy was used in the prehistoric era when monks used the gilded surfaces to ignite the scale of the altar. In 212 BC Archimedes burned the Roman fleet by exposing the sun from a distance, using reflective mirrors. In 1888, Edward Weston came up with a way to convert solar energy into mechanical energy by using a so-called thermodynamic process, creating an effort between hot and cold contact points between two different metals, such as nickel and iron.
Solar energy is used by direct heating or by mechanical and optical methods to convert it into electrical energy through the use of thermal motors, solar cells, and photovoltaic (PV) solar panels. This harness has helped solve many energy-related problems all around the world.

Bioenergy is renewable energy which is derived from so-called biomass; organic matter that stores solar radiation and converts it into chemical energy. Biomass is fuel and bioenergy is the energy that fuels contain. The form of fuel can include wood, sugar cane, straw, manure, and many other by-products from various agricultural operations. 
Biomass used as fuel is classified into several types, such as animal, wood, fertilizer and grass waste and biomass has no direct impact on its value as an energy source.
Bioenergy, in its narrowest sense, is similar to fossil fuels and biofuels, which is derived from vital sources. In its broader sense, it includes biomass, biomaterials that are used as biofuels, as well as the social, economic, scientific and technical fields associated with the use of biogenic sources as energy sources.

Sustainable biofuels: 
Biofuel is a strong competitor to oil in light of its high prices, which effectively contributes to the reduction and moderation of oil prices. It also plays a role in providing health supplies from alternative sources of energy
Biofuels are energy derived from both plant and animal organisms. They are the most important sources of renewable energy, unlike other natural resources such as oil, coal, all fossil fuels, and nuclear fuel. Biofuels are also obtained from the industrial analysis of crops, and residues such as straw, wood, manure, rice husk, sewage, waste decomposition, and food waste, which can be converted into biogas by anaerobic digestion.
Some countries have begun to grow certain types of plants specifically for use in biofuels, including corn and soybeans in the United States,  turnip in Europe,  sugar cane in Brazil and palm oil in Southeast Asia.

Wind energy: 
People rely on wind turbines to extract energy from the wind, generate electricity from it and use wind energy to produce mechanical energy in so-called windmills. Approximately 2% of the sunlight that falls on the Earth's surface turns into wind energy. This is a huge amount of energy, which exceeds the world's need for consumption in any year.
Wind energy has multiple uses, the most prominent are:

Pumping water with windmills; Windpump irrigation systems are widely distributed in Australia, parts of Africa, Asia, and Latin America. Wind power may soon be used to generate electricity on farms and homes, at a lower cost than fuel.
➤It moves ships and pushes their sails. 
Wind energy is highly reliable as a good substitute for fossil fuels, and is available permanently and continuously, and is considered one of the cleanest and environmentally friendly sources of energy.

Tidal energy: 
This kind of renewable energy depends on the tidal phenomena, which occur under the influence of gravity between the moon and the sun, and rotation of the Earth around its own axis. These phenomena are exploited depending on the currents stored in the water during the occurrence of tidal phenomena.
During the process, the height of the tides must be at least 5 m. Therefore, there are 100 sites in the world where this condition is available. The use of this technique in salt water displays the metal parts used to rust and therefore it is necessary to care and permanent maintenance as this may raise the costs and therefore low profit.
Wave and tidal energy technologies are used in many countries to generate electricity. This process is done by building dams or turbines, in order to relieve pressure on thermal power plants to reduce pollution caused by coal-fired or petrochemical plants.

Hydroelectric energy: 
Water has been a source of energy for centuries. It was used to move flour mills and grains, pump water to the Nile. The term hydroelectric is a comprehensive term for electricity and water. This type of energy is used in the exploitation of hydropower to generate electricity, and it is very clean and widespread energy. In the process of exploitation of this energy, it depends entirely on the potential of water or the energy of the situation, and converted into kinetic energy through the fall of water and flow from top to bottom, to manage the turbines generation, the generator starts rotating, and thus produces electricity.
One of the most important advantages of the use of hydropower is that it is environmentally friendly. This is useful in the process of regulating irrigation, besides electricity generation, does not require high costs for maintenance as water turbines are easy to install and operate and this process only requires some money to build a dam or a reservoir.
The most important forms of hydropower are:
  • Irrigation channels
  • Tidal Energy.
  • Wave energy.
  • Electric power.

Geothermal energy:
Geothermal energy efficiency and stations are relatively low. The temperature of water extracted from the ground is the main determinant of the efficiency of geothermal power plants during power generation, as a result of the low water temperature being lifted. Geothermal power stations have been characterized by low efficiency.
The geothermal power plant produces this type of energy from the Earth's surface. Geothermal energy is considered an environmentally friendly species because of its cleanness and regeneration and it is characterized by high temperature, and increases the higher the depth in the ground, and depends heavily on the generation of electricity. This process needs to reach deep underground, up to five kilometers, through the drilling of pipes and can be exploited and harnessed for the benefit of the world to supply energy. The most important sources of heat include:
  • Radioactivity.
  • Geothermal power plants.
  • Hot dry rock geothermal energy.

Benefits of renewable energy

The benefits of renewable energy vary according to the field in which they are used.

Military Academy: The most important applications of renewable energy in the military academies and army training centers, which can be used to facilitate life in new military cities include:
Solar heating system for military colleges, to meet the needs of students.
Supply of units with hot water, through the use of Solar Water Heaters.
Water desalination by solar energy.
Fixed wireless broadband solutions for rural electric cooperatives.

Residential and Commercial Area: Renewable energy is of great importance to the lives of the population. 
Heating water for use for cleaning, bathing, washing, and so using solar collectors, without converting it to any other form of energy, is the cheapest energy types altogether.
Solar water heating by using the solar absorber plate.

Agricultural field: There are many uses of renewable energy in agricultural use such as:
Drying of agricultural products.
Solar greenhouses for cold climates.

Industrial area: There are various applications in the industrial area such as:
➞Water distillation.
Charging batteries in TV and wireless terminals.
Lighting of navigational passages.
Navigational alarms.
Operating system speakers.
Charging of electric batteries.
Electricity generation in remote villages.

Renewable energy is the energy that is not implemented, permanent and immature, available in nature and constantly renewable because it is derived from nature and its components, for example, wind, water, sun and wave movement, and different from other energy sources such as fossil fuels and nuclear and petroleum and their derivatives. It has many advantages that encourage its use, as the whole future is now turning to the use of renewable energy sources in all matters of life, and to dispense with other sources of energy because they will be depleted sooner or later.
