The Pros and Cons of Hydropower

Published

pros and cons of hydropower

Hydroelectric energy, highlighted in the discussion on the pros and cons of hydropower, is widely utilized as a renewable energy source globally. A hydroelectric or hydroelectric generator, integral to this analysis, harnesses water flow to drive a turbine connected to a generator. The movement of the turbine rotates the generator, effectively producing electricity. Explore the benefits and drawbacks of this innovative energy solution to gain deeper insights into its role in sustainable power generation.

What is Hydroelectric Energy?

Hydroelectric energy is a renewable energy source like wind and solar energy. Among other renewable energy sources, the type of energy with the most well-established technology belongs to hydroelectricity. It is known that the power of water has been used since the early periods of civilization. People benefited from hydroelectric energy thanks to water mills and boats. Before the industrial revolution in the 19th century, water mills provided power for many production activities. However, due to technological inadequacies, the energy produced could not be stored and was insufficient for industrialization, which led people to turn to other fossil fuels, especially coal.

Hydraulic energy provides benefits in various fields such as modern agriculture, irrigation, tourism and sports activities. But the most important of all is the production of electricity. Today, thanks to water turbines, kinetic energy is obtained from the power of water. The first hydroelectric power plant was established in America in 1882. In 2016, the world’s largest hydroelectric power plant was established in China. It is known that this power plant has a production capacity of 22,400 MW.

How Does Hydroelectric Energy Work?

Water has high potential energy when stored behind the dam. When this water is released towards the turbines, this potential energy turns into kinetic energy. When water spins turbines, the turbines are connected to a generator and this rotational motion produces electrical energy.

How to Classify Hydroelectric Power Plants?

Hydroelectric power plants are classified according to 6 separate criteria. These criteria are as follows:

  • According to storage method
  • According to installed power
  • According to the typology of the dam body
  • According to the capacity to meet the needs of the national electricity system.
  • Depending on the location of the power plant building.

What are the Types of Hydroelectric Power Plants? 

Depending on the type of development, hydroelectric power plants can be divided into three types:

Water Retention Facilities: A large-scale water reservoir is obtained by establishing dams. The most common use of hydroelectric power plants is through dam installation. Electrical energy is produced by the water passing through the turbines in the dam.

Pumping Facilities: Pumping facilities are established as a second water reservoir at the bottom of the established dams. Pumping facilities are very similar to water retention facilities. Water stored for future use can be pumped to the upper reservoir when needed.

Stream Facilities: Electrical energy obtained from natural water flow. Part of the stream passes through turbines. Dam installation is not possible.

Part of a hydroelectric power plant

The hydroelectric power plant consists of the following parts:

Dams: These are responsible for intercepting rivers and maintaining water bodies (for example, reservoirs) before containment, creating a difference in the water used for energy production. Dams can be made of mud or concrete (most commonly used).

Spillway: They are responsible for releasing some of the water that stops passing through the engine room and can be used for irrigation needs. They are located on the main wall of the dam and can be bottom or surface. Huge amount of water is lost in the basin at the foot of the dam to avoid damage when the water falls.

Water intake : They are responsible for collecting the intercepted water and transporting it to the machine through forced channels or pipes. The water inlet has a gate to regulate the amount of water reaching the turbine and a filter to prevent the passage of foreign objects (logs, twigs, etc.).

Power plant : The machine (generator turbine, hydraulic turbine, shaft and generator) and control and regulation elements are located here. Has an inlet and outlet to leave the machine area without water during maintenance or disassembly.

Hydraulic turbines : They are responsible for using the energy of the water passing through them to produce rotational movement through their own axis. There are three main types: 

  • Pelton wheel, 
  • Francis turbine, and 
  • Kaplan turbine (or propeller).

Transformer – An electrical device is used to adjust the voltage in an alternating current circuit while keeping the power steady. This device can increase or decrease the voltage as needed.

Power transmission lines : cables that transmit the generated energy.

What are the Usage Areas of Hydroelectric Power Plants?

Electricity Production: Hydroelectric energy is mainly used to produce electrical energy. Hydroelectric power plants are favored due to their lower cost and less harmful impact on the environment compared to other energy sources. The installation of hydroelectric power plants is increasing because it does not pose serious threats to nature and human life, as in the installation of fossil fuels and nuclear power plants.

Agriculture: Thanks to hydroelectric energy, large agricultural areas can be irrigated. Flour can be produced by grinding grain with mills built with the power of water. The first civilization in history to establish hydroelectric power plants for the purpose of agricultural irrigation activities was the Egyptian civilization.

Industrial Use: It is known that bellows were driven by the establishment of hydroelectric facilities in the ancient civilization ages.

Use to Close the Energy Gap: As fossil fuels such as gasoline, coal and natural gas are becoming depleted, the trend towards other natural resources has increased to meet the energy needs. In addition to solar and wind energy, water power is also utilized in this context.

Pros of Hydroelectric Energy

There are a number of examples with the advantages of hydroelectric energy, also known as dams. Compared to fossil energies, this type of energy is a promising technology. Let’s see the advantages of this type of energy obtained from the movement of water.

It is a renewable and sustainable energy

The kinetic energy of flowing water is used to generate electricity from hydroelectric energy. Although it may cause some difficult and environmental climate problems, it is currently a strong and sustainable energy source.

It is an eco-friendly and clean energy source

The energy produced by hydroelectric power plants does not create toxic or greenhouse gasses that pollute the atmosphere. They release less greenhouse gasses than fossil-based power sources. This helps reduce climate change, acid rain and smog. It can also improve air quality because they do not emit air pollutants.

It is a useful system for sustainable development

Can develop in an economically viable, environmentally sound and socially responsible manner. Hydroelectric enterprises operated in this way represent the best concept of sustainable development. It attracts various industries and provides an overall boost to trade. 

It is the country’s domestic power source

Unlike fossil fuels, hydroelectric production does not require the system to be transported over long distances. There is no mining involved in the hydroelectric production in question. The power plant installed will convert water into energy.

Supports guaranteed energy and price stability

Despite expensive upfront building costs, hydroelectric power plants are a cost-competitive energy source. River water is a domestic resource that, unlike fuel oil or natural gas, is not subject to market fluctuations.

In addition, it is the single largest source of renewable electricity. The cost-benefit ratio, efficiency, flexibility, and reliability of thermal power plants contribute to optimizing their use.

Creates jobs and employment

Hydroelectric power plants are beneficial for regions with high unemployment rates. Building these plants provides job opportunities and enhances living standards for the local community. This leads to a rise in average income, boosting consumption and tax revenues.

Contributes to the development of remote communities

Hydroelectric power plants provide electricity to remote communities. It attracts the construction of highways, industry and commerce. All these activities are aimed at stimulating the economy of these remote areas and increasing access to education and healthcare. And it serves to improve the overall quality of life of residents.

Creates entertainment and tourism opportunities

The lake formed behind the dam can be used for activities such as fishing, boating and swimming. The water of the lake can also be used for irrigation purposes. Apart from this, large dams are becoming a hotspot for tourist attractions. It could provide an economic boost to nearby towns.

Cons of Hydroelectric Energy

Hydroelectric energy has advantages as well as disadvantages. The negative effects of these power plants are generally on the environment and local ecology. Here are some definite cons of hydroelectric power.

Environmental Impact

Disruption of natural water flow can have a huge impact on the environment and river ecosystem. Hydroelectric facilities may affect the lands in the dam area, forests, swamps and grasslands in the valley. Reservoirs can include people’s homes, natural areas, and farmland.

Areas that were previously covered with water may dry out, and dry ones may become covered with water. In turn, many animal and plant species may be mixed due to these changes in natural habitats. This may cause species to decline. It can also lead to imbalance in local ecosystems.

High construction costs

Constructing these plants and dams can be incredibly expensive. Additionally, projects take a long time to complete. It will need to be operated for a long time to earn back the money spent on construction.

Limited reservoirs

Although water is an unlimited resource, the conditions required to build a dam are limited. For the efficient production of hydroelectricity, large rivers or streams that will provide sufficient water are needed. It is difficult to find a suitable location that has a large water supply throughout the year, the right amount of water, and is close enough to existing power lines.

Drought potential is high

If hydroelectric energy is to be established, water abundance and drought cycles should be taken into consideration. This usually occurs in areas with local drought.

Border conflicts may occur

Rivers often represent the border between two countries. Decisions regarding the construction of hydroelectric power plants are in question. Both countries need to agree that this construction meets the goals of both countries.

If one country wants to build a hydroelectric power plant and the other country does not, this could even lead to wars between countries in the worst case.

May cause relocation due to flood risk

The local population living in the area may become vulnerable to floods due to possible water flows from dams. As a result, people are forced to relocate to facilitate the construction of the dam needed to generate hydropower. According to the report published in 2000, the World Commission on Dams   estimated that dams physically displaced 40-80 million people worldwide.

Causes deterioration of water quality

When dams are created, they limit water flow, which affects oxygen levels in the water. Lower oxygen levels behind the dam can also result in lower oxygen levels downstream. When there isn’t as much oxygen in the water, it’s harder for some fish species to survive, affecting river habitats.

Conclusion:

Do you think hydroelectric power plants should or should not be built according to their advantages and disadvantages? You can express your thoughts about the Advantages of Hydroelectric Energy in the comments. In this way, it can be determined whether the advantages or disadvantages of Hydroelectric Energy are dominant.

Ways to Identify Natural Raw Ruby Gemstone

Published

on

Natural Raw Ruby Gemstone

Recognizing the main types of fake jewelry is crucial when making a purchase, especially when considering Natural Raw Ruby Gemstone. In the following section, we will explore three methods for identification. One such method involves examining the color and luster to distinguish a genuine ruby from an imitation.

Signs of identifying the stone are the penetration of UV rays through the rock. One of the signs of recognizing the stone is the penetration of UV rays through the rock, and in various prosthetics these features are not Ruby . Generally, all Gemstones and jewelry have a similar and fake specimen which is much cheaper than the real specimen. How to recognize the main type of fake is always one of the most important things to consider when buying jewelry, and in the next section we will discuss three ways to identify this:

Color and luster

One way to identify the original ruby ​​is by imitating its color. Its main type is shiny and transparent in the light of lights and this is a characteristic of ruby ​​and in fake stones most of these colors are opaque. If the gemstone is dark red, it may be a garnet. Check everywhere for the solid red color of this stone and if you find spots that are scratched and have a different color, this indicates that it is fake.

Compare Ruby to a red glass

Gemstones and other types are forged using glass . If the glass and stone were similar, you can tell that the stone is fake.

Try to scratch its surface

Gemstones have a high degree of hardness and as mentioned above, one of the characteristics of Ruby is that only Diamond and one other stone can scratch it. Using the same feature of Ruby, you can largely distinguish the original type from the fake. Therefore, if everyone and objects except the above can scratch it, it indicates that the stone is fake and fake stones do not have this property of genuine ruby.

What are the characteristics of Natural Raw Ruby Gemstone?

Passioners may have heard the term Natural Raw Ruby Gemstone. This type of gemstone is also known as “red ruby ​​stone.” This is because rubies usually have a very distinctive color. 

Its beauty and bright red color make many people really want to own this gemstone. But unfortunately, real rubies are usually sold at very high prices. Therefore, it is not surprising that many people are looking for other alternatives by making imitations or imitations of real ruby ​​stones. 

Therefore, for those of you who like collecting gemstones and are planning to buy rubies, you must be careful and observant to see whether the rubies are genuine or fake. One way is to know what the characteristics of real ruby ​​are.

Check out the discussion below!

The durability of genuine ruby

Genuine ruby ​​has a very high level of durability. Its hardness reaches 9.0 on the Mohs scale. Ruby itself is a type of gemstone formed from the mineral corundum, namely a form of aluminum oxide crystal which turns out to be one of the strongest and most resistant minerals on earth.

If you try to scratch steel onto the surface of a real ruby, this gemstone will not leave the slightest scratch.

Real ruby ​​color

Genuine rubies have a bright red color and shine. In contrast, fake rubies usually have a dull red color. It does not produce a red glow. If you happen to see someone offering a gemstone that they call a ruby, but it is dark red, it is probably a garnet, not a ruby. 

Real rubies have stone grain

If observed using a magnifying glass, real rubies and fake rubies are very easy to distinguish.

Usually fake rubies, namely synthetic gemstones created in a laboratory, have no defects. The defect in question is in the form of stone fibers.

In contrast, real rubies consist of defects (cracks). This is very natural because real rubies are formed in nature. 

Another characteristic that can differentiate between real ruby ​​and fake ruby ​​is the bubbles in the stone. If you see bubbles in a ruby, it’s probably a fake ruby. 

Natural ruby ​​is light-transmitting

Try shining a flashlight at your ruby. If the stone transmits light and reflects light, it is most likely a genuine ruby.

Real ruby ​​reflects light

The reflection of light produced by genuine ruby ​​will sometimes form a six-point star or star-shaped beam, or three-ray. The form of light reflection is produced from the fibers contained in genuine ruby.  

Price of real ruby ​​stone

We tend to be tempted by cheaper prices for goods. Remember, real rubies are rare, strong and quality gemstones. Wherever it is, it will definitely be sold at a very high price. If you hear that someone is selling rubies at a low price, you should be careful. It’s likely a fake ruby. 

Certificate of authenticity

If you want to buy a real ruby, especially from a jewelry shop or from certain people, make sure the ruby ​​has a certificate stating its authenticity. Don’t spend a lot of money on fake gemstones!

These are some of the characteristics of real ruby ​​stones. Now you are interested and ready to buy real ruby ​​stones?

FAQs:

How can you recognize a real ruby?

Real rubies shine with a deep, vibrant, almost “traffic light” red.Fake gemstones lack radiance and may appear dull. For instance, if a gemstone appears dark red, it might be a garnet rather than a ruby.

What color is a real ruby?

The gemstone owes its red color to an addition of chromium and, in brownish tones, iron. From dark red to light red to an elegant pale red, rubies can be found in many variations.

How much does a real ruby ​​cost?

The price varies between a few hundred euros to a few thousand euros per carat , depending on the quality and rarity. On average, a ruby ​​of 1 carat in very good quality costs around €2,000; for special specimens in the premium segment, €5,000 is realistic in this size.

Hydroelectric energy has advantages as well as disadvantages. The negative effects of these power plants are generally on the environment and local ecology. Here are some definite cons of hydroelectric power.

Environmental Impact

Disruption of natural water flow can have a huge impact on the environment and river ecosystem. Hydroelectric facilities may affect the lands in the dam area, forests, swamps and grasslands in the valley. Reservoirs can include people’s homes, natural areas, and farmland.

Areas that were previously covered with water may dry out, and dry ones may become covered with water. In turn, many animal and plant species may be mixed due to these changes in natural habitats. This may cause species to decline. It can also lead to imbalance in local ecosystems.

High construction costs

Constructing these plants and dams can be incredibly expensive. Additionally, projects take a long time to complete. It will need to be operated for a long time to earn back the money spent on construction.

Limited reservoirs

Although water is an unlimited resource, the conditions required to build a dam are limited. For the efficient production of hydroelectricity, large rivers or streams that will provide sufficient water are needed. It is difficult to find a suitable location that has a large water supply throughout the year, the right amount of water, and is close enough to existing power lines.

Drought potential is high

If hydroelectric energy is to be established, water abundance and drought cycles should be taken into consideration. This usually occurs in areas with local drought.

Border conflicts may occur

Rivers often represent the border between two countries. Decisions regarding the construction of hydroelectric power plants are in question. Both countries need to agree that this construction meets the goals of both countries.

If one country wants to build a hydroelectric power plant and the other country does not, this could even lead to wars between countries in the worst case.

May cause relocation due to flood risk

The local population living in the area may become vulnerable to floods due to possible water flows from dams. As a result, people are forced to relocate to facilitate the construction of the dam needed to generate hydropower. According to the report published in 2000, the World Commission on Dams   estimated that dams physically displaced 40-80 million people worldwide.

Causes deterioration of water quality

When dams are created, they limit water flow, which affects oxygen levels in the water. Lower oxygen levels behind the dam can also result in lower oxygen levels downstream. When there isn’t as much oxygen in the water, it’s harder for some fish species to survive, affecting river habitats.

Conclusion:

Do you think hydroelectric power plants should or should not be built according to their advantages and disadvantages? You can express your thoughts about the Advantages of Hydroelectric Energy in the comments. In this way, it can be determined whether the advantages or disadvantages of Hydroelectric Energy are dominant.

Natural Raw Ruby Gemstone

Recognizing the main types of fake jewelry is crucial when making a purchase, especially when considering Natural Raw Ruby Gemstone. In the following section, we will explore three methods for identification. One such method involves examining the color and luster to distinguish a genuine ruby from an imitation.

Signs of identifying the stone are the penetration of UV rays through the rock. One of the signs of recognizing the stone is the penetration of UV rays through the rock, and in various prosthetics these features are not Ruby . Generally, all Gemstones and jewelry have a similar and fake specimen which is much cheaper than the real specimen. How to recognize the main type of fake is always one of the most important things to consider when buying jewelry, and in the next section we will discuss three ways to identify this:

Color and luster

One way to identify the original ruby ​​is by imitating its color. Its main type is shiny and transparent in the light of lights and this is a characteristic of ruby ​​and in fake stones most of these colors are opaque. If the gemstone is dark red, it may be a garnet. Check everywhere for the solid red color of this stone and if you find spots that are scratched and have a different color, this indicates that it is fake.

Compare Ruby to a red glass

Gemstones and other types are forged using glass . If the glass and stone were similar, you can tell that the stone is fake.

Try to scratch its surface

Gemstones have a high degree of hardness and as mentioned above, one of the characteristics of Ruby is that only Diamond and one other stone can scratch it. Using the same feature of Ruby, you can largely distinguish the original type from the fake. Therefore, if everyone and objects except the above can scratch it, it indicates that the stone is fake and fake stones do not have this property of genuine ruby.

What are the characteristics of Natural Raw Ruby Gemstone?

Passioners may have heard the term Natural Raw Ruby Gemstone. This type of gemstone is also known as “red ruby ​​stone.” This is because rubies usually have a very distinctive color. 

Its beauty and bright red color make many people really want to own this gemstone. But unfortunately, real rubies are usually sold at very high prices. Therefore, it is not surprising that many people are looking for other alternatives by making imitations or imitations of real ruby ​​stones. 

Therefore, for those of you who like collecting gemstones and are planning to buy rubies, you must be careful and observant to see whether the rubies are genuine or fake. One way is to know what the characteristics of real ruby ​​are.

Check out the discussion below!

The durability of genuine ruby

Genuine ruby ​​has a very high level of durability. Its hardness reaches 9.0 on the Mohs scale. Ruby itself is a type of gemstone formed from the mineral corundum, namely a form of aluminum oxide crystal which turns out to be one of the strongest and most resistant minerals on earth.

If you try to scratch steel onto the surface of a real ruby, this gemstone will not leave the slightest scratch.

Real ruby ​​color

Genuine rubies have a bright red color and shine. In contrast, fake rubies usually have a dull red color. It does not produce a red glow. If you happen to see someone offering a gemstone that they call a ruby, but it is dark red, it is probably a garnet, not a ruby. 

Real rubies have stone grain

If observed using a magnifying glass, real rubies and fake rubies are very easy to distinguish.

Usually fake rubies, namely synthetic gemstones created in a laboratory, have no defects. The defect in question is in the form of stone fibers.

In contrast, real rubies consist of defects (cracks). This is very natural because real rubies are formed in nature. 

Another characteristic that can differentiate between real ruby ​​and fake ruby ​​is the bubbles in the stone. If you see bubbles in a ruby, it’s probably a fake ruby. 

Natural ruby ​​is light-transmitting

Try shining a flashlight at your ruby. If the stone transmits light and reflects light, it is most likely a genuine ruby.

Real ruby ​​reflects light

The reflection of light produced by genuine ruby ​​will sometimes form a six-point star or star-shaped beam, or three-ray. The form of light reflection is produced from the fibers contained in genuine ruby.  

Price of real ruby ​​stone

We tend to be tempted by cheaper prices for goods. Remember, real rubies are rare, strong and quality gemstones. Wherever it is, it will definitely be sold at a very high price. If you hear that someone is selling rubies at a low price, you should be careful. It’s likely a fake ruby. 

Certificate of authenticity

If you want to buy a real ruby, especially from a jewelry shop or from certain people, make sure the ruby ​​has a certificate stating its authenticity. Don’t spend a lot of money on fake gemstones!

These are some of the characteristics of real ruby ​​stones. Now you are interested and ready to buy real ruby ​​stones?

FAQs:

How can you recognize a real ruby?

Real rubies shine with a deep, vibrant, almost “traffic light” red.Fake gemstones lack radiance and may appear dull. For instance, if a gemstone appears dark red, it might be a garnet rather than a ruby.

What color is a real ruby?

The gemstone owes its red color to an addition of chromium and, in brownish tones, iron. From dark red to light red to an elegant pale red, rubies can be found in many variations.

How much does a real ruby ​​cost?

The price varies between a few hundred euros to a few thousand euros per carat , depending on the quality and rarity. On average, a ruby ​​of 1 carat in very good quality costs around €2,000; for special specimens in the premium segment, €5,000 is realistic in this size.
