What are the advantages of renewable energy?

The idea aims to use renewable energy in reaching sustainable and more clean development, and renewable energy has several benefits whose benefits belong to man and the environment, in the following is an explanation of the most important of these advantages:^(٢)

• Renewed and cannot be executed: It remains with a person staying on the face of the earth, as water flows constantly, and the sun shines every day, and light winds do not stop, while strong winds are permanent in some places that provide the world with a large energy source.
• Environment friendly: Unlike fossil fuel that produces carbon, the cost of installing some types is somewhat low.
• You do not need maintenance and the cost of maintenance is appropriate: Energy generation from wind and solar energy using photovoltaic panels is less expensive than gas generation.
• Safe on man: They are not flammable, and their use helps the world get rid of these dangerous and durable materials need to maintain.
• Provide money: With progress, increased efficiency and spread among people, their costs will become simple, as they reduce monthly electrical bills.
• Not produced greenhouses such as carbon dioxide: This means reducing the phenomenon of global warming and stopping their consensus, as abnormal materials created what is known as the climate crisis, specifically after the industrial revolution, forest fires, and the speed of melting ice.
• Raise the country’s economy level: This is because it reduces the import of energy from the producing countries or its purchases, which means the country’s self -producing energy.
• Maintains human health: Since it does not send harmful gases in the atmosphere, which means reducing the percentage of diseases spread among people.
• Provides new jobs for job seekers: Its installation and maintenance operations require a great effort, which means reducing unemployment levels among the world’s population and creating new job opportunities.

Types of renewable energy

Renewable energy is derived from a variety of sources, and each source produces a kind of energy below for it:

Solar energy

Solar energy (Solar Energy) is the energy that is stretched from the sun, and this solar energy is large as the energy that reaches the Earth in one hour is greater than the energy that the world consumes in a year, and solar energy is produced from the sun using solar panels, as these panels contain cells that absorb heat and turn them into consumption energy.^(٣)

It is characterized by being reliable as it depends on the sun, provides new job opportunities for young people, as it is not polluting the environment, and produces sufficient electricity for the place where it is installed and sometimes more.^(٣)

Biological energy

Bionergy Basics It is the energy that derives from more than one source of organic materials, which is known as the vital mass, is used to produce fuel, heat, and electricity, and is characterized by being safe on the environment and human, constantly renewed, and raises the level of the country’s economy, and the most important sources are: agricultural crop waste, forest waste after cutting trees, microalgies, wooden waste, and hypocrisy.^(٤)

The productive energy of it has many uses such as gasoline and aircraft fuel, in addition to the reuse of carbon and waste in the manufacture of fuel, trucks, planes and ships, all of which are small emissions.^(٤)

That is, the biomass is transforming into liquid state called BiofuelsAnd this fuel has two types: ethanol and vital diesel, which is characterized by being low carbon emissions, and vital energy is produced through several methods: combustion, bacteria analyzing, and converting mass to gas or liquid, and one of its most important characteristics is that it benefits from harmful substances to the environment and transforms them to energy such as plastic materials, chemicals and fertilizers, which means that it is a healthy alternative to fossil fuel.^(٤)

Wind energy

Wind Energy It is the most common type of energy at the present time, and its use is still increasing because its costs are relatively simple and large, specifically in the countries of the world that include areas with strong strong winds, and this energy is derived by fixing large and giant turbines in the wind areas, then its feathers move with the wind move to produce large energy such as electricity.^(٥)

The use of wind energy for the first time in Denmark, and the winds have the ability to generate electrical energy from kinetic energy, that is, the amount of electricity produced depends on the speed of the movement of the turbine feathers.^(٥)

Aramatic energy

Hydroelectric power It is one of the energy forms that are produced from water sources, specifically the dam tanks and flowing water flowing. With the movement of water, the installed turbines move and rotate, then turn the resulting mechanical energy into electrical energy.^(٦)

It appeared in the past, but begins in the grain mills, where the water energy was responsible for operating these mills, and it is one of the most used and most important energy, as it constitutes 17% of the total electricity production, it is abundant in China, Brazil and Canada.^(٦)

Earth thermal energy

Geothermal Energy It is the heat that is stretched from the Earth’s heat, and is used to warm buildings, generate electricity, and shower.^(٧)

It was classified as renewed energy due to; Because the earth contains permanent flammable and heat materials, resulting from slow decomposition processes of radioactive particles in the ground and rocks, and these fascinated materials approach the ground specifically the places of volcanoes, then their temperature absorbs rocks and groundwater found in tanks below the earth, so that their temperature rises and is used for productive purposes by man.^(٧)

The energy of the tide and the islands

Either Tidal Energy Energy It derives from the rise and lower seas and oceans, and this energy is somewhat modern, and it was established for the first time in France, and the engineers are still searching for techniques to benefit from them without significant costs with a simple effect on the environment, and produced by placing turbines in the areas of tidal occurrence, then the kinetic energy is converted into electrical energy, and it has several types that differ in the method of production of energy.^(٨)

Renewable energy uses

Renewable energy is used today in many areas, and it is as follows:

In the military field

Renewable energy is used in the military field as follows:^(٩)

• Reducing wars and conflicts based on the occupation of areas that contain oil, fuel and gases.
• Benefiting from renewable energy resources and electricity resulting in the operation of homes and military buildings, in order to preserve a permanent energy source that is not affected in the event of wars, conflicts, or disasters.
• Reducing the phenomenon of global warming, which causes drought, climate change and duties, which constitute a security threat to the country.

In the commercial home field

The uses of renewable energy are in the field of homes and trade as follows:^(١٠)

• Providing free electricity for homes and large stores and reducing expenses for paying electrical bills.
• The increase in projects that include the production of renewable energy, which means the emergence of new mechanisms and new pieces, the percentage of sales also increases to benefit the competent shops.
• The use of vast lands in the installation of energy production means, which are rented or bought from their owners to get them off with profits.

In the agricultural field

And its use in this field as follows:^(١١)

• Shipping batteries and large generators with renewable energy, for use in remote agricultural areas instead of expensive diesel generators.
• Use it in the areas of agriculture, such as irrigation with solar energy and drying food.
• Reducing agricultural production costs such as harvesting, storage, cooling and drying.

In the industrial field

And in what follows its most important uses:^(١٢)

• Reducing industrial costs by providing electricity in sufficient quantities to operate these mechanisms without significant costs.
• Reducing the prices of produced materials; Due to the low production costs.
• Increased job opportunities centered on the manufacture of energy production mechanisms.

Disadvantages of renewable energy

As for the defects of renewable energy and its negatives, they are several problems, the most important of which are:^(١٣)

• The productive capacity of electricity is still sufficient for entire human consumption.
• Some see it unreliable because it depends on changing sources such as the sun that partially disappears in the winter, and the winds that calm down from time to time.
• You need great efficiency when installing it well without you need a lot of maintenance.
• You need a relatively large financial amount to install due to the high level of its equipment and the difficulty of installing it.
• You need a large space that can accommodate its huge equipment.

Summary

Renewable energy appeared after the great world went towards the non -renewable energy that is about to exist, which threatens the entire humanity, and this explains the resort of researchers and engineers to harness renewable energy such as the sun, wind, the heat of the earth, the semints, the islands, rivers and organic material Military, industrial, commercial, and home.
