Advantages of Green Energy and Top Three Common Forms
Green energy is the energy that is obtained from inexhaustible sources and is often described as clean energy. It does not produce environmental pollution residues such as fossils like coal, petroleum, which produces carbon dioxide, or nuclear energy that emits toxic radiation, therefore, it is better for the environment.
There are many forms of green energy, including:
1. Solar energy
The energy that reaches the earth from the sun, because of the chemical reactions that occur on it, which produce enormous energy, and has been exploited in water heating systems that rely on solar panels. Also used in water distillation to be drinkable, and heating of houses and buildings through architecture.
One of the most complex applications is the conversion to electricity, using solar cells that consist of semiconductors, and when the fall of the sunlight on them are moving electrons, and moving towards the electrical connector on the other side of the solar cells, and thus running the electricity in it. Panel Source is currently exploiting this in many fields, like residential green energy.
2. Wind energy
This type of energy has been used to move windmills to grind grain and transport water. Today, it is used to generate electricity through the so-called turbines, which are large fans with high altitudes and different shapes, large farms housing such turbines are called wind farms and can be put on land on large tracts of land. These areas can be used for other activities such as agriculture.
For offshore wind farms, they are very expensive in construction and in maintenance but produce higher electrical power than land farms, and irrigation farms. It can serve an entire residential city of electric power, with the knowledge that the higher the turbine, the greater the electric power generated, given the wind speed at the top.
Is organic material that can be obtained from natural materials such as wood, natural fertilizers, oils, as well as methane, which is produced by organic waste. This energy can be used in animal pens, but this energy is not as clean as other forms of renewable energy. Methane increases global warming, and wood and fertilizer combustion produce carbon dioxide. There are other examples of renewable energy such as water, land, and tidal energy which all have green footprints and is not harmful to the environment.
Advantages of Green Energy
There is a range of features and advantages of green energy, including:
- Green energy is well established throughout the world.
- Green energy is environmentally friendly and clean.
- It is permanent and renewable.
- It is easy to use based on simple techniques and mechanisms.
- It is very economical.
- Is an important factor in environmental, social and all fields.
- Help creates new job opportunities.
- Helps to mitigate the damage of gas and thermal emissions.
- Prevent harmful acid rain.
- Limit waste collection in all its forms. The abandonment of crops from chemical contaminants, thus raising agricultural productivity.
- They use uncomplicated techniques and can be manufactured locally in developing countries.
Bonus: It can be used to generate electricity for residential homes.
Solar Energy and its Advantages
Humans have used solar energy since ancient times in many different applications, including the drying of crops before conservation and heating of houses. Archimedes used solar energy to burn the Roman warship in 212 BC. He concentrated solar radiation on the enemy army ships using many of metal shields. Babylonian women also used golden vessels to concentrate solar radiation and to obtain fire.
Many scientists have used solar energy to melt metals, heat the air, convert water to steam, and distil water, and there are global plants for irrigation using solar energy. Today man is still inventing renewable means to take advantage of solar energy by converting it to other forms.
The advantages of solar energy:
- Environmentally safe
- Decreases pollution
The technology used in solar energy is simple and uncomplicated compared to others more commonly used.
Solar energy conversion
Solar energy can be transformed into other forms of energy, such as electric power and thermal energy. Photovoltaic conversion is the conversion of solar energy directly into electrical energy using solar cells, in which case it is important to use materials that work on photoelectric conversion, known as semiconductors, the most important of which is silicon and germanium.
This phenomenon was known by 19th-century physicists to revolutionize the concepts of physics and the valuable information known at the time that light has the ability to release electrons that exist in some metals. Blue light has that ability more than yellow light, for instance. Einstein received the Nobel Prize for his ability to explain this phenomenon in 1921 AD.
At present, the presence of solar cells, whether in homes, roads, or institutions and companies, is obvious. The most important features of these cells are:
- They do not consist of moving parts
- They are stable
- They do not need any kind of fuel
- Don’t pollute the atmosphere
- Sustainable, it does not need frequent maintenance and is not expensive
The principle of work is very simple, and it does not consist of any kind of optical lenses or light concentrates. Solar panels are installed on the roofs of buildings in certain ways, for energy production, and their efficiency to provide electricity is equal to 20%, while 80% is used to provide heat.
Solar energy in homes
It is important to emphasize that the ability to benefit from solar energy is associated with its existence, and that is why scientists are busy finding ways to store this energy. There are many ways to store it such as thermal, electrical, mechanical, chemical, and magnetic.
Solar energy in homes is used for many applications, the most important of which are home heating, water heating, electric power conversion, and the use of some simple electrical appliances in homes.
We trust that you have enjoyed learning more about solar energy and how it is utilized in homes across the globe. Even though it is not readily available to all and installation costs a lot, we believe that this will change and become more available to all.
