What is Wind Turbine? How Wind Turbines Works and uses

Wind energy is a teeming energy source which never seems to expire. Hence human race can not go out of it unless we exist. This plentiful and powerful natural resource can replace conventional electricity production procedures. Moreover the power generation from wind turbines does not pollute the air. It is one of the world’s fastest emerging energy sources for electricity production.

Building Renewable Energy Turbines
The traditional methods of producing electricity have resulted in climate changes because of high rate pollution it discharges. Wind power turbines can provide clean electricity which can cover its cost in 5 to 6 months easily. Wind turbines have been most popular energy source in Europe because of its environment nature and no harm to animals and human beings. Wind mills are also liked by their aesthetic features, because they tend to increase the beauty of the land. A windmill gives us great impression, even If we observe it from miles. This is the only power plant that has so far killed no human being during the process of electricity. The design and structure of wind mills is equally sturdy and beautiful. They are designed so well that they can even withstand tornadoes. Thus we need to build more wind mills in suitable regions as a substitute for conventional and expensive electricity power houses to rectify and recover the climate disasters.

Types of Wind Turbines 
There are many types of wind turbines but most commonly used wind turbines are horizontal and vertical wind turbines. The purpose of the wind generators is to convert the kinetic energy of the wind into usable electricity. These turbines are often implanted in wind farms to generate large amount of electricity. The basic structure of modern wind mills is same but they constitute many different components like pitch, rotor, blade, gear box, pod, and generator, high and low speed shafts, yaw drive and yaw motor, tower, controller, wind vane, nacelle and brake. The horizontal axis wind turbines contain a generator, rotor shaft along with a gear box. The gear box converts the slow rotation of the blades into quick and efficient rotation again. The vertical axis wind turbines on the other have rotor which is placed vertically. The vertical axis wind turbines are used in areas where the direction of wind is highly variable. The structure of vertical axis wind turbines makes them simple to use because they do not need be adjusted again and again. These renewable energy source is completely safe and environment friendly.

Cost of Wind Turbines & advantages of wind turbines
The cost of deploying wind turbines is dependent upon many factors. The main factors may include initial financing, type of wind turbine, installation and maintenance charges, location of the project and the brand which is being used. Users who are currently using the wind power turbines for years are enjoying the benefits because now they say that the cost of electricity produced by wind turbines is equal to traditional methods. However the use of these wind turbines is environment friendly and safe for human health. No reason how useful these wind turbines are they are still an expensive project. This is the reason why most of the underdeveloped countries are not still utilizing this alternative energy source. The cost of deploying wind generators also vary with per mega watt generation of electricity. The wind turbine which generates approximately 100KW electric power cost almost $ 3000 to $6000.that means a 10KW energy machine costs $15,000 to $25,000. governments are capable to overlook the cost of these wind turbines by looking at the ability of these wind mills. The most obvious reason of using wind mills for producing mechanical and electrical energy is their security and safety to use.

What is Wind Power or Wind Energy

Wind power or wind energy just like solar energy and falls in the category of renewable energy source. Wind pressure is a renewable energy source because it can be used again and again without the fear of it being diminished or become scarce. The quality of wind power to exist in abundance without depletion along with its environment friendly nature makes it desirable to use as an alternative source of energy.

Types & Structure of Wind Turbines
The wind turbines have three basic components, The Mast, a Rotor and a Pod. The mast is made up of steel and it is foundation on which other components of the wind turbine work. It is inserted into the soil and a solid concrete base supports its unyielding grip. The wind turbines are installed very high in the air in order to utilize the very high wind pressure. Wind mills are almost 80m to 100 m tall. The purpose of implanting high wind mills is to receive uninterrupted wind pressure at all times. The rotor on the other hand holds the blades of wind mill. These turbine blades are made up of material which has strong resistance against changing weathers. The material which is usually used is fiberglass or carbon fiber. It is this rotor which converts the kinetic energy of wind into mechanical energy for further uses. If the mechanical energy is sued to support cutting of woods it is termed as windmill. However if this mechanical energy is converted to electricity it is known as wind generators. The pod third and last important component which helps the rotor wings to convert the kinetic energy into electricity.

How electricity is produced by Wind Power, How Wind Energy is Produced
The useful and unique energy resource can be utilized in different ways to generate electricity. However the most common way is to wind turbines for this purpose. A wind turbine is a rotating machine, this machine works by converting the energy from the wind into kinetic energy which is further changed to electric current. The energy from the wind is converted to electric current in aero generators. Modern wind turbines are really fast and they are controlled by computers. Any modern wind turbine can work on a speed of 200 miles per hour. Electricity is produced with the rotation of axle of rotor. This electricity is transferred to users with the cables inside the base of the mast. The structure of wind turbines is often supported and controlled by automatic computer system. This system ensures the orientation of the blades at a 90 degree angle to the direction of wind. This automatic system also improves the efficiency of the wind turbines by adjusting the angle in order to take full advantage of wind power.

Research & development in Wind Power and Wind Energy
The windmills power generators have very low fuel cost. Moreover they produce electricity in an environment friendly way. Therefore the potential market for these wind turbines exists. The initial cost of installation is the first consideration which can effect its market growth. However the long term benefits and low maintenance cost makes it desirable to deploy. The development and research in this sector has already helped in improving its structure and efficiency. According to the facts and figure the wind power demand in USA and Germany in 2008 was 4150 MW and 585 MW. However the challenge of installing wind turbines come with the wind power in countries. USA still has the highest wind power utilization of about 52 MW per hour. The problem with all renewable energy sources is that most of the countries of the world lack the basic infrastructure and resources needed to deploy this technology. The major problems like annual production and capital requirements need to be addressed in order to promote renewable energy sources.

What is Wave Power or Wave Energy, How Wave Power Works

When the power of the waves present on the surface of the ocean is used to convert it into useful form of energy it is known as wave power. Wave power is different from tidal power and ocean currents. Wave power can be converted into electricity, water pumps and water desalination. This is not a very popular form of energy. The energy from the ocean waves is extracted by devices either from the motion of waves or movements in the deep sea level.

History of Wave Power
The history of wave power is very old; it was in 1799 when Girard and his son for the first time presented a proposal to have patent rights to use this power. Then in 1910 in Paris again Bochaux Praceique asked government to use this power to light his house. Scientist realized its importance but it was in 1973 when the growing oil crises arouse the desire to find alternative sources of power. Many research scientists from renowned universities started working on this project like Stephen Salter, johnnes Falnes, Micheal E and John Newman. However this development fell drastically in 1980’s when the problem of oil was resolved.

Disadvantages of Wave Power, Challenges to Wave Power
Deployment of wave power technologies has many downsides and challenges. The devices require regular and strong wave energy in order to operate efficiently. The typical wave power ratio is 4 whereas the peak power capacity should be ten times more than that. The fluctuations in wave powers sometimes due to storm in ocean might result in project failure. The working of the device has to be fast and it requires fast transformation of waves into electric current. The major challenge is to align the fast electricity generators with steady turbines. The wave power is high but the speed is low hence the electric generator has to work accordingly. The damage to devices is obvious because the devices have to withstand the tough conditions like high salt content in changing waves and storms. The cost of producing electricity is high and so as the cost of maintenance and replacement of equipments. The total capital cost of wave power projects is high and it includes power take off system, mooring system and electricity delivery cost. Here are some hazards to nature as well by deploying wave power houses. The wave power plants generate high noise pollution and it tends to affect the marine life. It can also snatch the bread and butter of local fisherman.

What are Wind turbines and How Wind Turbines Works
It is important to understand the working of the electricity generating wave power devices; the reason is that this would help in overcoming the deficiencies in the process. The working of the electric wind turbines can be described by simple example of swimming pool. When the air is blown in and out of the water chamber it helps in generating waves. This movement of waves forces the air present in the chamber of the air to turn on the wind turbine. A wind turbine is placed in the hole of the air chamber and it is operated when the pressure of air increases due to the movement of water. This wind turbine is connected to the generator, which is then used to produce electric current. The energy and power we draw from the movement of waves in and out of the chamber is a renewable energy sources. This process produces much noise pollution but it can be controlled by installing silencers at both ends. There are many methods of installing the wave power plant like off shore project, on shore project and shoreline etc. one example of shoreline energy converter is situated in Isaly Island Scotland known as Limpet.

What is Tidal Energy or Tidal Power, How Tidal Power Works

The energy of the tides which is transformed into useful electricity and other power sources is known as tidal energy or tidal power. The term tide means rise and fall of ocean and sea level due to gravitational strength from moon and rotation of earth. This is a renewable energy source which is under development and not many people know about it. Tidal energy or Tidal power is more efficient and reliable way of generating electricity as compared to wind mills and solar energy systems.

How Tidal Power or Tidal Energy Works, Electricity Generation from Tidal Waves
Tidal waves are a way different process to generate electricity from the movement of moon and its effect on ocean level. The energy is generated by the movement of water when the tides are produced in the ocean by the gravitational movement of moon and sun. The magnitude of tide is dependent on the movement and change in the position of sun and the moon. The tidal force is infinite as long as the sun and the moon survive. The energy of tidal waves can be converted to electricity by making dams and barrages. The energy from the tidal wave is stored by installing a tidal generator. The greater the velocity of the tide, greater would be the electricity generation. There are three broad categories & types of tidal power.

How Tidal Power Works, How Tidal Energy Generated
Fig: How Tidal Power Works Tidal Stream System

The tidal stream system uses the kinetic energy generated by the tides and carries it to power turbines which result in electricity generation.

Tidal Stream System, Offshore Tidal Turbines
Fig: Tidal Stream System also knows as offshore turbines

The Tidal barrages are designed to utilize the potential energy created due to the difference in the level (height) of the tidal waves.

Tidal Lagoons
Tidal lagoons are a kin to barrages except for their ability to produce power in constant flow.

how tidal lagoon works

Fig: How Tidal Lagoon Works

Tidal power plants are also an environment friendly way of generating electricity. Minor climate changes are predicted by using the tidal energy of the earth over the period of centuries.

How Tidal Power Works, How Tidal Power Plant Works
A tidal range of about 7mm is required for the economical and smooth operations of electricity generators. The tidal power plant constitutes of a barrage along an estuary in order to block the incoming and outgoing tide. The areas like pacific northwestern region are an ideal location to deploy power generators. The reason is the steady fluctuation of tides up to 12 feet in a day. The coast of Alaska and Washington are considered to have exceptional tidal pressure. The biggest tidal power generator is situated at La Rance River in northern coasts of France. This project produces about 240 MW of electricity. This station was built in 1996. More and more studies re conducted to analyze the potential of rivers and oceans in different parts of the world. Tidal power plants are an expensive way of generating electricity but this is highly efficient.

Advantages & Uses of Tidal Energy
Tidal energy is a renewable energy source and it does not release any acids, harmful fluids and gases while generating electricity. Tidal energy is also a reasonable substitute for nuclear energy. Hence it can also protect us from harmful radiations of nuclear. Change in tidal flow by deploying barrages is however tend to affect the shoreline and related eco system. However scientist says that the impact of these tidal waves is different in different regions. The change in the local tides near LA Rance is negligible but near Fundy Bay it is more which can reduce the tidal wave to about 15 cm. tidal power generators can be also helpful in increasing the efficiency of traditional power grids. This tidal power can be used to replace conventional power projects which release greenhouse gases and dangerous acids. The emission of the dangerous gases tends to quickly affect the environment as compared to the tidal waves. The climate changes caused by the tidal waves require centuries to slow the process of local tides.

Sustainable Vs Renewable Energy

It is generally considering that both are the same. These are two names for one concept. But this is wrong perception by the common folks. It is supposed that present sources of energy are continuously decreasing so there should be an alternate solution.

There is also another perception that present energy sources are less safeguard for environment. This concept results into renewable energy sources. Some of the examples of renewable energy are tidal, wave, geothermal and wind energies. As oil and gas are present at large scale and sustainable energy sources they are emitting carbon dioxide. This carbon dioxide is polluting the environment. In polluted environment energy consumed double as compared to clean environment. All the renewable energy resources are considered clean and safe technologies for energy consumption.

Following are the differences between sustainable and renewable energy;

Fundamental Difference Between Sustainable & Renewable Energy
Coal, oil and gas all are fossil fuels and are sustainable but they are not renewable. All renewable energy sources are sustainable. In fact they are designed for the abundance and sustenance features.

Energy Level
Fossil fuels for example coal, oil and gas are the sources of energy which give one part of energy while rest of the two parts are waste. This waste is in the form of carbon dioxide which is harmful gas for our environment.
All the renewable energy sources are considered free from harmful effects.
Nuclear Energy
Nuclear energy is sustainable.
Nuclear energy is not renewable source.

Pollution Factor
Some of the sustainable sources like coal, gas and oil when consume energy they also emit carbon dioxide in the atmosphere. In short, they make environment pollutant. Renewable energy sources do not produce carbon dioxide. There pollution factor is nearly zero.

Energy conservation
The term sustainable energy is introduced for the sake of conservation of energy reservoir in the long run. It is considered that coal and oil would become scarce in the near future. This supposition originates the concept of energy conservation. Nuclear energy is a sustainable energy and a big reservoir of energy for the long term usage.
Renewable energy sources are developed with the concept of abundance and presence. It is considered that present energy sources are going to be finish soon. Therefore some sort of energy reservoir should be there for the future consideration.

Natural existence
Mostly sustainable energy sources are natural like fossil fuels. For example coal, oil and gas are produced naturally no human arrangements are needed. All the renewable energy sources are artificial. They exist when special arrangements are there for them.

Theory of Abundance
Theory of abundance is applied to the renewable energy as basic concept behind their origin is the availability of energy in the future. Sustainable energy source like fossil fuel is considered enough for the coming few decades.

Energy Level

Some of the sustainable energy sources are consist of one part of energy and two parts of waste. Renewable energy sources emits less than zero % waste. They are like energy tablets which has no side effects.

We are comparing two terms;
Sustainable Energy Source
Renewable Energy Source

Look at last two parts both are same. It means both are the carriers of energy. Environment concern regarding global warming put forth the concept of alternative energy which results into clean and hygiene source of energy like renewable energy. This renewable energy lessens the fear of polluted environment and gives surety for the future availability of energy. Sustainable energy gives the concept of enough reservoirs for future prospects.


What is Sustainable Energy

With the terrific increase in population a relatively new approach is introducing for the consumption of energy. Environment is the focal point for the better survival of living beings on earth. There is need of taking some precautionary measurements. From this scenario comes the concept of sustainable energy.

Energy is the basic ingredient of life. Spending a healthy life is dependent on energy to consume it properly. We need energy to perform different tasks and activities. We need energy to run industries, and to fulfill other necessities of life. Now the question is where does this energy come from? Till now the greatest source of energy is fossil fuel and is considered reliable for the coming century as well. But the dilemma of the situation is if this source of energy will be consumed by the present speed it will soon come to an end. There is need to give specific consideration towards the sustainable use of energy.

But what is the meaning of this sustainable energy? If we see the constituent of sustainable energy, we will get the idea about what actually it is. Sustainable energy is the renewable energy with efficient use. Now there are two things which we have to consider when consuming energy. First thing is to explore and preferred to use renewable energy resources and while using renewable energy its consumption should be proficient. So sustainable energy means consumption of energy from the present resources wisely so that it does not harm the future prospects.

We are still depending upon the energy getting from fossil fuel. Fossil fuel is the most widely used energy source but its continuous use is a threat to the environmental pollution. As the demand of energy consumption is increasingly continuously, there is need to explore some more energy resources. These energy resources are in the form of renewable energy. These renewable energy resources are produced primarily from solar energy. Similarly there are wind and wave energy sources available. There is one disadvantage of these energy sources even though they are substantial in energy supplies they are not reliable due to dependent on weather. If weather is fine they are doing well but in bad weather they are not reliable source even stop working. There are other sources like hydro-power and bio mass if used wisely could be reliable and long lasting. Here comes the time for energy efficiency.

To utilize energy efficiently makes it sustainable. Everything live on this planet needs some sort of energy. This energy comes from different sources. It is estimated that these sources are going to be end if used unwisely. There should be some proper arrangement so that every single unit of energy should be consumed. And while consumed every bit of energy from different sources it should be kept in mind that remaining amount is the treasure for future generation.

Coal, oil and gas which are fossil fuels are supposed to be enough till coming two centuries if used properly. There is only one drawback that they make the environment polluted and this is a dangerous one. Next is the nuclear which is reliable also as a sustainable source of energy but it is even 10 time dangerous than fossil fuel in respect of pollution whereas sustainable energy is a peculiar term for the clean and safe source of energy.

The clean, pure, non-pollutant and safe energy is called sustainable energy available for the future generation as well without harming the present objectives and good source for future as well. As fossil and nuclear energy are not considered renewable so they are not sustainable. As we know that renewable energy with efficient use is considered sustainable so there is need to pay attention to the renewable energy resources. These are wind energy, concept of windmills is not new; tidal energy produced through turbine, wave energy produced by the process of oscillation and geothermal found in the deep recesses of earth. All are used as renewable energy sources and considered sustainable. Now there is only need to make the environment less polluted by using renewable energy sources. Because more pollution more energy consumption less pollution less energy consumption. So we can make the environment free from pollution by using renewable sources and this will enable us to use energy efficiently.

What is Steam Power

Steam power is a good source of energy. It has been using at industrial level since very long. Invented by Thomas Newcomen in the seventeenth century, concept of steam power has been revolutionized the industrial platform. Previously, steam power was used at larger level and did not consider suitable for residential level. Even nuclear units were run through steam power but little consideration given to other application where steam power could be utilized.

Technology development has changed most of the things in our surrounding. Steam Power technology is not only changing our ways of life but also making easy and convenient. Till now this steam power is a new thing and people are hesitating as how does it work at small level. The installation of steam power may be very difficult. Therefore it is necessary to understand the mechanism of steam power engine.

Steam Power Setup

To utilize the steam power on a small level is based on

  1. A boiler
  2. Furnace
  3. Steam engine
  4. Re-circulator point

Note= There is no specific design for steam power setup. This system takes the shape according to the location and surrounding.

Arrangement for Steam Power

To build a steam power system, the first consideration you have to pay is to the furnace. You have to decide which type of fuel you are going to use for fueling the furnace. There are different types of fuel like gas, wood, or oil. Every type of fueling needs its own separate arrangement. It’s according to the environment of the area, home location etc.

The next step is selection of the type and size of boiler for steam power setup. There are two different types of boiler; fire-tube boiler and water-tube boiler. Fire-tube boiler is an old design which is not very reliable. There is always danger of its leakage or especially boiler explodes. It should keep in mind while arranging fire-tube boiler that its material should be heavy-duty. There is one more drawback in this module that it cannot endure the pressure more than 250 psi. As fire-tube boiler is not a success, it always avoids using in home environment.

The second option is much more reliable and prevailing swiftly on a residential level is known as water-tube boiler. Due to its durability and work efficiency it is getting popularity. As it is designed directly in a tube shape instead of tank shape so is effective. This shape is an additional advantage of this module survival. This module has many plus points;

  1. The steam is easily and quickly collected in a tube than tank or drum.
  2. Tube can endures pressure up to 5000 psi two times more than tank.
  3. Tube takes less time to turn water into steam than tank. Where tank makes steam in half an hour where tube makes steam not more than five minutes.
  4. Water-tube boiler is cost-effective.
  5. Water-tube boiler has not threat of exploding. It can leak sometimes but not explodes.

Although water-tube boiler has many plus points yet there are couples of negative points as well to be mentioned here.

Pressure fluctuation is not possible in water-tube boiler but in fire-tube boiler.

In case of water-tube leakage, breathing in that environment is dangerous for lungs system.

All these precautionary measurements should be considered before the installation of any type of steam power engine.

This boiler is attached to the steam power engine. The steam engine is made up of two parts; outer and inner. At the outer part steam reaches near to the inner part as a career of energy or power. This outer part is the combusting engine where the steam as a source of energy is kept. The inner part of the engine is called the chest. This chest is consist of a valves further attached to the piston. With the movement of valves when allows steam passes from whole it pushes the piston back and forth motion. The chest is the cylinder then piston connecting to the crankshaft with the help of rod. Crankshaft is the point where drives are attached whatever you want to activate with the help of steam power. These drives could be a generator to produce electricity for the household or just attached to the water pumps.

Applications of Steam Power

Steam power is used to run water pumps to irrigate the crop fields.

  1. Steam power engines when attached to generator are able to produce electricity. It could be used at household level or industrial level depends upon the size of the steam engine.
  2. Steam boats are also designed to utilize steam power.
  3. Factories are run by steam power engines.
  4. Locomotives are steam power-driven.

What is Solar Renewable Energy? Uses, Types & Comparison

Solar energy is the term used for the heat and light which the sunlight contains. Sunlight reaches to earth in the form of photons. Photons are energy packets that contain light in it. Solar energy is considered as a renewable energy source because it does not destroy our eco system and is present naturally in the environment.

Comparison of Renewable Solar Energy with other renewable energies

Solar renewable energy has edge over all other renewable energy sources. This competitive edge is because of the abundance and availability of this natural resource. Other renewable energy sources like wind, rain and bio fuels have many constraints. For example wind is either weather specific or it is limited to coastal regions, Rainfall varies with region to region. While sun is everywhere and it is the free resource. No one can stop sunlight to travel its way to earth, because this energy source is not the property of any state or person. Another attribute which makes it desirable to use is that it is available both in developed and under developed countries of the world in equal intensity. There is no licensing and constraints to use it. Moreover there are no production tools or strategies required to avail this abundant natural resource.

How to generate electricity from Solar Power?

Solar power is the form of energy that helps in generation of electricity from the sun rays. There are many methods to generate electric current using sunlight but the most common methods are photo voltaic and concentrated solar power. Photo voltaic contains an array of solar cells which are pressed in solar panels. These solar panels are protected and framed by a glass sheet. This sheet does not allow any impurities to pass in. hence only sun rays can make their way in. These solar panels are made up of conductive materials like impure silicon and copper indium mostly. These conductors help and support the flow of electrons, thus the heat present on the solar panels is able to generate direct electric current. This electric current cannot support the electrical devices. Therefore it is converted to alternative current by using inverter and battery. Photo voltaic energy is growing rapidly and it is so far the only rapidly progressing renewable energy technology. Concentrating solar power systems work on the principle of converging the sunlight form many kilometers to single focal point. The concentrated energy stored in this form is converted to thermal energy which is utilized to support photo voltaic then. The solar energy stored by CSP is also helpful in running steam turbines.

Uses & Applications of Solar Renewable Energy

Solar renewable energy is considered most environments friendly for cooking purposes. The rural or poor areas where there is abundance of sunlight and forests solar cookers have been introduced. This overture will prevent the process of deforestation and the smoke resulting from burning wood. This renewable energy source is used to provide heating and cooling space facilities. Also this precious energy is a safe substitute for electric lights. The installation of solar street lights can save useful electricity in light and can help us to lower utility bills. Therefore the applications of solar energy are unlimited now solar energy is supporting military operations. It is providing portable power systems to travelers. It is used to run wind turbines, steam turbines hence reducing the pollution effect. Solar energy is used as passive and active energy forms for ventilation to heating water collectors respectively. Solar energy is the safest energy source which has no side effects to human health whether it is used to generate electricity or cooking food. Active and solar heating processes are both renewable energy sources because both work on utilizing natural resource sunlight in combination with wind mills.

What is Soft Energy

If a man from past comes here, he will really be surprised as it is the same planet where he lived once. We are now living in a technology saturated zone. Soft Energy Technology is the latest edition. Soft Energy Technology is more advanced more sophisticated in use. Soft Energy is comprises of five features. These five features basically define the Soft Energy Technology.
Energy is called as soft if;

  1. It is renewable
  2. It is in diverse form
  3. energy efficient
  4. It is essentially simple and supple
  5. It does not compromise over quality and quantity


Soft Energy Overview

An appropriate example of soft energy is solar energy. It is recognized as soft energy because it is renewable. Living things are using solar energy as it is a major source of vitamin D. When it is renewed it is used in the form of heat and electricity so it is renewable energy as well. Another aspect of this solar energy is its freedom of use. No one can stop you if you arrange personal set up in the form of large or small solar panels. Solar energy is achieved in two forms;
Express Solar energy

In this way energy is directly used with the help of radioactivity or convection or conduction phenomenon. In this way there is no need of any mechanical device for its conversion.
Circuitous Solar Energy

For this method you have to put solar panels which are directly attached to the driver like generator to produce electricity or to the machines dependent on solar energy.
Important Aspect of Soft Energy

An important aspect of Soft energy is it freedom of use. All the soft energies are not only beneficial but also open to all. A person with sufficient investment can set up his own Soft Energy Point to get benefit from it either using it directly or by mechanical set up. It is not the property of any community, group, and country. This freedom of use makes the soft energy more popular and non-political source of energy.


Advantages of Soft Energy

Soft Energy according to its feature is very advantageous for all not nationally but internationally as well.

  1. It is an easy to use source so anyone can use it which indirectly helps in developing equal races.
  2. It helps to divert the load of prime energy users to supple and sophisticated soft energy source.
  3. Raise the economy level of average citizens.
  4. Energy is very important factor in daily life so soft energy is there to save the people from compromise on their basic need.
  5. Developed countries can raise their economy by consuming soft energy sources. This would secure and enhance their monetary level.
  6. Soft energy sources cannot be monopolized by any sector, group or region.
  7. Soft energy sources are pollution free so are welcomed heartily.
  8. It compensates the other sustainable and non-sustainable energy sources in the long run.
  9. All the soft energies are energy efficient.
  10. It gives satisfaction and relaxation as are free from tax, excise duty or other Government obstacles so are non-political source and socially compatible.


The concept of soft energy is relatively new and most of the people are not aware from its unlimited benefits. It is presumed that in the future all the energy consumption will divert to soft energy sources. The reason behind this assumption is its non-pollutant feature. Global warming has been reached its alarming stage. There is need to aware the people and forcefully direct them to the use of soft energy to save the earth from destruction.

What is Renewable Energy technology, Types & Uses

Renewable energy technology is under the phase of development. There are many technologies which are associated with the use of renewable energy sources like solar power, wind power, tides, hydroelectric power, nuclear power and geothermal energy. These energy sources are able to fulfill the energy needs.

Technologies Associated with Solar Energies
The solar energy is the most widely used form of energy. This is the reason why there is more development in this field as compared to other forms of renewable energy source. The widespread solar technologies include solar panels, concentrated solar power plants, and updraft solar towers, concentrate photo voltaic and portable solar technologies. Solar panels are the most popular way of generating electric current form the small solar field usually deploying 15 to 20 solar panels. This technique is known as array of photo voltaic panels. Concentrated solar power plants are based on the principle of converging the light from many miles at one point for focus. This technique is helpful in increasing the overall efficacy of the plant. The portable solar technologies are another way ofs increasing the demand for solar technologies. The portable solar technology chargers, solar traveler and hand bags, mobile solar kits are some important inventions of the century. All these renewable technologies are in the early stage of their development. Hence the cost associated with these renewable technologies is very high which is expected to lower down in 5 years.

Uses of Renewable Technologies
Renewable energy sources like biomass are associated with the invention of environment friendly engines. These engines are not only bio fuel friendly but also they are environment friendly. The bio fuels such as ethanol and methane have helped in the development of environment train engines, car engines moreover the production of these bio-fuels have to undergo many technological processes like digestion, fermentation and gasification. The power from the wind energy is available by deploying automatic wind turbines. These wind turbines are based on the technology of using kinetic energy of wind and converting it to electricity by using motor present in the windmill. The modern wind turbines are based on the aero technologies and are not operated manually. These wind turbines are operated and controlled largely by computer systems. The use of computer system helps the wind turbines to adjust the position of blades in correct direction with the wind. The use of geo thermal energy is highly technology dependent because one cannot make use of this technology if does not have the drilling facility. This direct heat is extracted form the earth using earth tubes, heat ex changers. Hydroelectric power plants are based on the two basic types of water storage criterion like pumped storage hydroelectricity power plants and large electricity generators implanted on the dams.

Renewable Technologies in the World, Renewable Technology Used In Different Countries

Different types of renewable technologies are used in different parts of the world depending upon the climate conditions in the different parts of the world. For example USA has the largest solar power plants. European Union possesses most of the largest wind power plants in the world. The biggest tidal power project is situated at La Rance River in France. China is the leading country which has the maximum number of hydroelectric power plants. In addition to these major multinationals are also investing in making renewable energy technologies like LG, Samsung and Solar tech. more awareness bout the use of these technologies created through internet, TV and print .media. The use of renewable technologies improves health. These technologies are environment friendly because of them does not involve any burning processes. Though till now these technologies are very expensive now but government projects can help and support to promote the use of important renewable technologies.
