l have always loved robots since I was a little boy. I remember back in the days of “Transformers” and “Voltron”, I used to wait impatiently for those shows to come on. Then when the show finally starts I was glued to the TV like gum stuck in ones hair. No one could piy me away from my precious robot showsl As the years passes my body grew and my intellect grew too. A lot of things I cherished in my childhood fated, things like playing handball, making cities. With my Legos, draWIng battles that were fought With stick figures and riding my bicycle. Now I cherish things that are more complex like my relationship With friends, my computer, my car and classical music. But one thing that love now and in my childhood is my love for robots. I don‘t know why, but they never cease to spark my imagination With their complicated components and their power to do things regular humans can‘t. What Will it be like to be strapped to a five-story giant robot of unbelievable firepower?

There is this one popular anime series called Gundam, It is about these seven giant robots piloted by seven kids that fight for freedom and injustice. I have collected two of the seven robots. I will be describing my favorite model of the two, Wing Zero. Every time I look at my Wing Zero Model my imagination flows with what technology would bring people in the future. Wing Zero is piloted by the leader of the seven children his name is Iowa. Iowa is a small-framed child in his early teens. He has brown hair that combed to one side and sticks out like the bill of a baseball cap. He usually Wears a black tank top and sweat shorts like any boy you would see in our schools. But Atowa is no regular boy. He Was trained since he was a kid in the artificial space colonies to be a stand-alone fighter and pilot.

He has large cold unemotional brown eyes that stare at you Without any fear. He moves With the speed of a cheetah and strikes. With the power of a dragon to take down his enemies. Easily taking down many Men that are twtce his size. He is able to dodges bullets and he is able to fire back with deadly accuracy. Iowa speaks very little, What he says are well thought out and is law to his peers. He cares for nothing and no one. The only thing he cares for is completing his objectives for the space colonies. Altova is even more deadly in his Gundam “Wing Zero”, the robot five stories tall are made of gundamlium a rare and super strong metal that is only found in space. But my 8-inch tall model of “Wing Zero” is made of plastic, Wing Zero is the most powerful of the seven Gundams, able to lay waste to anything in the path of its energy cannon for hundreds of miles. It is the only Gundam that is able to transform into a jet.

It can jet thru great distances in the atmosphere or space. The robot form is used when maximum firepower and untility is required. Wing Zero‘s most noticeable characteristic is the giant golden V that protrudes out the top of its head. The V is stationed on its forehead and protrudes almost the whole vertical height of its head. The head its self is very small compared to the rest of its body. The head is grayish and looks like a samurai helmet from ancient Japan, On the both sides of its head were a persons ears should be are two holes housing two rapid fire cannons able to tear thru even the toughest armor. The face of Wing Zero looks well fortified and protected by the rest of the head. It has two eyes that are well imbedded below the forehead and glow wtth amber green that gives you hints of the robots massive firepower. It has no nose but two black horizontal slits and no mouth but something that looks like the medical masks doctors wear when performing surgery.

But instead of it been round the protrusion is an elongated square. The main torso is comprised of two sections. The upper torso is white colored the front extends outwards. On the left and right sides of the upper torso are two yellow colored jet intakes. The lower torso has one large protective piece of armor in the front, one white piece on the back and two dark blue side armor plates that shield the hips. 0n Wing Zero‘s shoulders are two giant blue-colored jet engines used in its jet mode. The two arms of the robot are white and are connected by gray-colored Joints. The black hands carry two massive energy cannons that when combined creates one super colossal energy cannon able to destroy whole armies. The cannons themselves are gray colored and each of the cannons is about half the height oi the robot its self. The legs of the robot are white. The lower portion is noticeably wider and thicker than the upper half above the knees joints.

The knees joints are gray like its other joints and are protected by two blue vertical extensions. one for each knee. The feet are dark blue and look like women’s high heel shoes but the arch is way in the back and the heel’s width is the Whole Width of the foot and is not small and pointy like high-heeled shoes. The Front of each foot there is an overhang of two white flaps of armor. This Robot Model is a scaled-down model of Wing Zero an awesome testimony of power and of man‘s creative mind to create super complex technologic wonders to accomplish. What the human body cannot do in the Gundam universe. My model of Wing Zero brings out the imagination in me of the future, Maybe one day we will be able to buy a real-life Wing Zero in the local giant robot dealer, maybe glorious battles for injustice and freedom would be fought in these technological marvels or maybe there will never be giant robots. One can only imagine about robots now, It is a childhood romance that Will follow me till then end of my days.

The manufacturing of photovoltaic cells is diverse in the photovoltaic power industry. Many participants have developed their own proprietary manufacturing processes to construct their own proprietary technology. Several technologies of manufacturing photovoltaic systems exist in the industry. These technologies arguably represent the past and future of the photovoltaic manufacturing industry. Methods used in the industry include: 1. Monocrystalline and multicrystalline production, 2. String Ribbon Technology, 3. Copper Indium Gallium Selenide (CIGS), and 4. Thin-film Technology.

The ability of a company to utilize the most cost effective manufacturing method will lead to a competitive advantage. Being the low cost manufacturer is essential to success in the photovoltaic manufacturing industry. Regardless of the technology used in the manufacturing process, there exist uniform manufacturing steps for all companies within the industry. These steps include silicon crystal growing or casting plants, photovoltaic cell manufacturing, module assembly, and systems assembly. Silicon crystal growing or casting plants refers to producing the silicon for photovoltaics.

This involves converting sand into silicon bricks and finally into wafers. Photovoltaic plant assemblies take the finished silicon wafers through a high technology semiconductor process to create working photovoltaic cells. Module Assembly refers to combining the silicon wafers into a laminated photovoltaic module. The final step, Systems Assembly, refers to the mechanical and electrical component of the finished product. Although some companies have vertically integrated all steps, typically, companies specialize in one or two steps.

This analysis is focused on companies involved in the second and third steps of the manufacturing process. The most important material for making photovoltaic cells is silicon. Although there are other photovoltaic technologies that rely on other semiconductors, like amorphous silicon, cadmium telluride, copper indium diselenide, and organic cells, silicon remains the dominant raw material used within the industry. Crystalline silicon technology is the earliest form of manufacturing and continues to be the dominant technique in the market, representing approximately 94% of solar market sales in 2005 (Fast Solar Energy Facts).

Conventional crystalline silicon technology involves sawing thin wafers from solid crystalline silicon blocks. Crystalline silicon products are known for their reliability, performance and longevity. However, factors such as high waste from wafer cutting, complex processing procedures, high energy requirements, and high initial capital expenditures have limited the ability of these manufacturers to decrease costs and maximize outputs. Monocrystalline production requires taking a seed of single-crystal silicon and placing it in contact with the top surface of molten silicon.

Atoms of the molten silicon solidify in the pattern of the seed and extend the single-crystal structure. The final product is a thin monocrystalline wafer (How BP Makes Solar). The complementary silicon production technique is multicrystalline production. This is a casting method where pieces of silicon are melted in large ceramic crucibles to form an ingot, or brick of silicon. Each ingot is cut into smaller bricks, which are cut into wafers. The wafers go through a series of chemical coatings and metallization processes to complete the assembly.

Ultimately, both methods produce silicon wafers that are consolidated to form a photovoltaic cell (How BP Makes Solar). Companies using these techniques include BP Solar, Kyocera, Solar Power Industries, GE, Sanyo, Sharp, Shell Solar, and SunPower. Another manufacturing technique in the industry is String Ribbon technology developed by Evergreen Solar. Conventional silicon techniques such as monocrystalline and multicrystalline manufacturing are based on energy intensive processes used to melt the silicon into ingots and then cut the ingots into silicon wafers.

String Ribbon technology uses surface tension to form silicon wafers. The making of a string ribbon wafer is like making a soap bubble. Instead of a ring forming the bubble, this technology uses two parallel wires to form a thin-film of silicon. With this proprietary technique, two heat-resistant wires are pulled vertically through a silicon melt, and the molten silicon ps and solidifies between the strings (String Ribbon). This technique creates a thin silicon wafer and minimizes the typically energy intensive process.

A fourth manufacturing technology is Copper Indium Gallium Selenide (CIGS). This technology represents a competitive advantage for the main developer of this technique, HelioVolt. Copper Indium Gallium Selenide (CIGS) is the best solar-absorbing material (Thin Film). With high yields from their substrate, HelioVolt is able to claim higher watts per cost when manufacturing this technique. In addition, this technique allows solar film to be applied to many different materials, such as glass, steel, metal, composites and some polymers.

This places them in a good position for the emerging building integrated photovoltaic (BIPV) products market, where photovoltaic cells are incorporated into building materials. The final method for photovoltaic cell manufacturing is thin-film technology. While most major photovoltaic power manufacturers currently rely on crystalline silicon technology for their photovoltaic cell production, thin-film technology allows for decreased costs due to less consumption of raw materials.

Thin-film technology involves depositing several thin layers of silicon on a substrate to make a photovoltaic cell. Although thin-film techniques generally use materials more efficiently than traditional crystalline manufacturing techniques, the high capital costs, low manufacturing yields, lower conversion efficiency, and reduced product performance and reliability have hindered the adoption of this technology. Despite these obstacles, thin-film technology manufacturing represents a potential method for the production of photovoltaic cells in the photovoltaic manufacturing industry.

Companies in the industry using this technology include Energy Conversion Devices (ECD), EPVSolar, and PowerFilm Technologies. Despite these manufacturing technique differences, general trends in the industry have emerged to facilitate manufacturing. The ability to produce photovoltaic cells cheaply is integral to success in this industry. The strategies used in the industry include cost reductions enabled by increased line efficiencies, vertical integration, improved economies of scale, and expansion of manufacturing capacity to low-cost manufacturing locations.

Companies use lean manufacturing and other continuous improvement strategies to streamline their manufacturing. Because this is an emerging industry, plants are engineered with state-of-the-art technology to increase efficiencies and eliminate waste. This forward thinking strategy is aligned with the technology and industry mission. Vertical integration is accomplished by producing wafers, cells and panels in one location. These silicon products can be sold individually or integrated into a finished photovoltaic module or customized system.

Although some industry members purchase silicon ingots from outside manufacturers, the optimum situation is to perform all the necessary steps of producing photovoltaic cells at one location and within one company. Economies of scale and low-cost manufacturing are achieved through reproducing identical plants throughout the world in order to meet the rising demand. Participants in the industry have assembled plants around the world, not only to be in close proximity to demand, but also to seek competitive edge through low-cost manufacturing.

With the advent of technology everything in this world has changed in some or little ways, in the field of automobile human beings has made a tremendous progress which is implausible. With increase in consumption of fossils fuels it has become a global issue to reduce pollution, moreover to reduce the dependency of countries on other countries for fuel sources. So, car companies came up with idea to make cars which run on an alternative power source. They used natural gas and more sources to run cars and ended up to a result of chargeable cars. More information about electric cars will be given in the subsequent paragraphs.

Thesis: Electric cars are not as bad as people think they are. Firstly this essay will tell about one of the global problem air pollution, which is not created by electric cars, then about the maintenance cost of the electric cars that is much lesser than gas powered cars and finally about safety which is the major thing to be considered and it will change the mindset of individual’s regarding electric cars. Even though electric cars sound like a bad idea but in reality they aren’t that bad.

First and the foremost thing about electric cars is that they do not make as much pollution as the gasoline cars do, in comparison the electric cars make 60% less pollution than the gas powered cars. According to (EIA, 2015) in 1990s, the government of transportation measured the highest emission rate of carbon dioxide of US economy and the transportation sector is projected to generate nearly half of the 40% rise in US carbo dioxide emission forecast for 2025 (as cited in Romm, 2006).

The biggest argument against electric vehicles in most cases is that to run these vehicles the electricity produced will cause some emissions, but it is clear as water that electric vehicles do not have exhaust pipes. So, there is no chance of any carbon emissions in any conditions.

Moreover, the electric cars are facing a tough competition from improved gas power vehicles indeed two decades ago when tailpipe emissions standard were being developed requiring 0.02 g/mile of nitrogen, few expected that this could be achieved by internal combustion engine vehicles running on reformulated gasoline but new generation hybrid cars like Toyota prius have raised the bar for future of electric cars, a 30% to 50% reduction in greenhouse gas emission and a 90% reduction in tailpipe emission ( as cited in Romm, 2006)

Secondly, maintenance price is another important thing that masses take car about when they buy a new car or any other vehicle. An internal combustion engine has number of different parts moving in different directions which is a complex mechanism, so it needs serious machinery and regular services which pinch owners pocket badly, electric cars are simple with only one moving part that means no complex structure and less service cost.

Last but not least is the safety, which is the first priority of every car owner as gasoline powered cars are dangerous from this point of view. Sometimes due to overheating of engine or any other mechanical problem in the car engine can cause an engine bore explosion, due to which the car can catch fire which is a serious danger. On the other hand in case of electric cars there is no piston in the engine so the person and his vehicle both are safe from this danger.

Nearly all electric vehicles sold in North America meet or exceed the safety ratings of the leading gas-powered vehicles in their class. Thanks to massive battery packs required to store energy that makes them go, plug-in vehicles are significantly heavier than gas cars. This in itself is a major advantage. This helps to prevent rollover, which is particularly deadly and at the times unpredictable variety of accident (as cited in McDonald, 2016).

To conclude it can be said that in future these cars will become the basis of transportation, because people are using fossil fuels at a high rate that it will become extinct. Moreover, it is also the duty of every individual to save these resources for the upcoming generations.

One of the biggest causes of air pollution in cities is motor vehicles. Traditional vehicles run on diesel and petrol, which emit hydrocarbons, carbon dioxide, and nitrogen oxides. These substances contribute primarily to global warming, an effect whose impact is being felt increasingly in the world today. Inhaling these gases also causes health problems such as lung cancer, brain diseases, and heart attack. A first step to reversing pollution would be to stop the primary cause, which is the emission of toxic gases by motor vehicles. Electric vehicles are the world’s safest alternative to conventional cars, as they are one of the most eco-friendly solutions to pollution.

Electric vehicles (EV’s) are vehicles that use an electric motor to run instead of an internal combustion engine. The vehicle uses a large traction battery pack to power the electric motor and must be plugged into a charging station or wall outlet to charge. Because it runs on electricity, the vehicle emits no exhaust from a tailpipe and does not contain the typical liquid fuel components, such as a fuel pump, fuel line, or fuel tank. [Afdc, 2019]. Plug-in hybrids (PHEVs) combine an electric motor with an efficient petrol or diesel engine, and so usually produce some tailpipe emissions throughout a journey; although on average at a far lower level than conventional petrol or diesel cars.

There are many benefits that come from switching to electric cars. The main one is reducing air pollution. Clean air is one of the most crucial requirements of a clean and healthy environment. Pure electric vehicles do not emit hydrocarbons and other harmful chemicals, which are harmful when inhaled and can cause diseases such as lung cancer. Electric cars are also much quieter than traditional ones, which means they produce less sound, hence lesser noise pollution.

Moreover, electric cars use renewable energy. The car is powered by an array of rechargeable batteries which use solar energy and green power, hence do not have greenhouse gas emissions. This reduces reliance on fossil fuels, which are likely to become exhausted shortly. Also, carbon emissions produced these fossil fuels lead to climate change and global warming. By switching to an electric car, a person would be contributing significantly to taking care of our home planet.

Recently, eco-friendly materials have been adopted for the production of EV’s. For instance, the Ford Focus Electric is made up of recycled materials and the padding is made out of bio-based materials. The Nissan Leaf’s interior and bodywork are partly made out of green materials such as recycled water bottles, plastic bags, old car parts, and even second-hand home appliances. [Ergon.com, 2019]

It must be noted. However, electric cars are not a perfect solution to pollution. They run on electricity, which is still produced by burning fossil fuels. Batteries used are sophisticated and therefore require a lot of energy to produce. While the car itself will not emit carbon gases, the power plants that charge the batteries produce a substantial amount of it. This has led many critics to argue that the carbon footprint of an electric car is similar to that of a traditional vehicle. Batteries are also made from metals which must be mined. The mining process poses a whole new set of ecological problems such as deforestation, water, and noise pollution and contamination of soil. A solution would be to produce cars that run on renewable resources instead of batteries produced using fossil fuels.

While electric cars may not be entirely eco-friendly, they are the best alternative to conventional cars as a solution to environmental pollution. They do not pollute the environment, can run on with renewable materials and can be produced using eco-friendly materials. The switch to electric cars is inevitable if the world is to make any significant difference in protecting the environment.

Electric cars uses traction or electric motors to propel the engine. The cars may be powered via a system by the means of electricity that comes from “off vehicle sources”, an electric generator, solar panel or a battery contained within the car that converts fuels to electricity. The traditional needs fuel simply because the car need the power and it can only obtain it from the engine. Electric cars are slowly becoming popular around the globe as opposed to the traditional cars. The electric cars have advantages and demerits over traditional cars and vice versa.

The rising in technology and the need to protect our environment is constantly supporting the individuals to buy electric cars as compared to the traditional cars. The sue of electric improves on the battery life of the car but it Is also associated to a few drawbacks for example, charging it for a long period time, issues on performance, high cost, limited range and the scarcity of charging stations tend to fade away.

Previous results have shown that countries like Denmark, Italy, and Belgium do differ in the way they develop positive attitudes and intentions towards the electric cars basis of their green self-identity (Barbarossa, 2015). Automotive giants are committed to convert to the production of electric cars only in the near future, as the customers are able to get affordable options. Therefore changing the public opinion that electric cars are associated with the elite.

The electric cars require low maintenance as opposed to traditional cars that require quite moderate maintenance. This is because electric cars have very few moving parts and most of the moving part in electric cars rarely break and do not need fixing on a regular basis. For the many years to come, this will help save on money and time, no of renting cars when ones car is being services or when there is a failure in transmissions. Despite all these, there are brakes that need to be maintained, but they do last longer compared to the brakes in traditional cars. The biggest issue with electric cars is changing of the battery, but the newest models today comes with a battery that has a warranty of eight years. These batteries in a mild climate can be used up to fifteen years.

Virtually, there are no vibrations and the engine produces very little noise in electric cars. In traditional cars, the vibration and the noise produced by the engine is quite significant, hence having a different experience. Driving electric cars is really interesting one the immediate thing you notice when driving an electric car is the lack of noise. The electric cars are very quiet both on the inside and on the outside.

The traditional cars are really noisy both from the outside and the inside, when one steps on the accelerator on an electric it makes a slight noise that fades away but in a traditional cars stepping on the accelerator reduces a continuous noise that only stops once the accelerator is not stepped on. Since the noises produced by electric cars are quite low, the future that we are looking into will be silent and peaceful.

The charging and recharging of electric cars can be done either in a charging station or at home and the physical presence of anyone is not needed in the 0cahrgingor recharging process. But for the traditional cars, refueling and fueling can only be done in any petrol station and one need to be physically present for the whole process to take place. For refueling processes of the electric cars, you do not to change oil or even buy gas, you only need to plug in either at work, at home or on the road and charge.

Electric vehicles are considered to be one of the most important ways for any country to solve a series of energy problems such as urban smog, energy supply security and turning to green development (Lin et al, 2018). The power from renewable sources gets into the electric car batteries. Charging your car with non- renewable electricity can be domestically generated.

In conclusion, the generation to come will have to make a decision on whether to go with electric cars or not. Soon those with habitual doubts on technology that do criticizes over high cost, issues on performance, limited range, charging for a long period of time, and the inadequacy of the charging stations will fall upon deaf ears. We are looking for a future that will be filled with calmness and peace, we will be able to achieve this if we choose the electric cars that virtually makes no noise over the traditional cars.

Renewable Energy Essay – 1 (200 Words)

Renewable energy is a sustainable source that is not very harmful to both the environment and human health. In fact, renewable energy is generated from natural energy sources such are the sun, wind, water, earth and plants.

At present, the cost of fuel is increasing due to the continuously increasing population of the world and in parallel the conventional fuel reserves are also getting reduced continuously. In such a situation, all the people have started searching for alternative sources of energy. Renewable energy with immense potential for future is becoming a necessity of today.

In the last three decades, research and development has taken place in renewable energy. The latest technologies are coming out, which are enough to reduce people’s dependence on traditional energy sources like coal, oil and natural gas. It is gradually becoming clear that renewable energy sources can prove to be a better alternative than fossil fuels.

Another great thing is that green energy options have far fewer side effects on the environment than fossil fuels, because they do not emit greenhouse gases.

The supply of the renewable energy becomes uninterrupted and it also becomes cost effective. Thus renewable energy resources are purely simple, ubiquitous and readily available throughout the world, including rural and remote areas where electricity has not yet been reached.

Renewable Energy Essay – 2 (300 Words)

Introduction

In the last few decades, due to the ever-increasing average population of the world, modern technological developments and the increasing rate of electrification, the demand for energy has increased globally. Environmental experts believe that this demand can be met through various renewable energy options.

Importance of Renewable Energy

With the expansion of wind, water power and solar energy in the world, as well as power generation from geothermal energy, the world’s maximum power needs can be met. By adopting renewable energy, air pollution can be reduced by improving the quality of the world environment. Renewable energy sources are safe, self-sustaining and reliable, with huge amounts available year-round.

Most of the world’s energy is derived from petroleum, natural gas, wood, sunlight and uranium. In the coming few thousand years only, our traditional energy sources will be exhausted. We have finished it in a few minutes, which nature has spent millions of years in making. Environmental pollution, social and economic pressures and political upsets make the problem more serious. Therefore, the development and use of renewable energy sources and having strong will power for this is the need of the day.

This requires massive use of renewable energy as well as strengthening of its storage capacity. To adopt renewable energy voluntarily, it has to be emotionally and socially connected. To increase their credibility, more control over renewable energy resources and better performance will have to be ensured.

Government assistance of 210 billion rupees (US $ 3.1 billion) is planned to the solar panel manufacturing industry to increase India’s photovoltaic capacity. Under this scheme, India is committed to generate 40 percent of the total energy by 2030 with green energy.

Conclusion

In view of limited energy resources and high cost of imports, Prime Minister wants to focus on innovation and research in renewable energy sectors like solar and wind energy. This will provide electricity to every family at a reasonable price.

Renewable Energy Essay – 3 (400 Words)

Introduction

Renewable energy is being used as an alternative to conventional energy. Due to development of technology, renewable energy can be used easily in daily life and for commercial consumption. This type of energy does not pollute the atmosphere; hence it is also called clean fuel. This fuel or energy will never run out, it can be replenished. Unlimited reserves of renewable energy resources are available everywhere in the world. It requires less expenditure and less capital investment.

A Stable Solution to Energy Requirement

We all know that mineral and fossil fuels are rapidly ending and the day is not far when petroleum and coal will be completely extinct from the earth. Many oil wells around the world have started drying. Apart from this, many coal reserves are rapidly depleted, due to which it has become a big problem for some countries that are completely dependent on coal and petroleum for energy production.

In contrast, renewable energy sources such as sun, wind and biomass are stable and sustainable solutions for energy derived from them is very important. That is why a need to adopt these sources of renewable energy to solve energy needs. The production and use of solar energy requires photovoltaic cells and solar panels, and the production of hydroelectric power requires the construction of hydroelectric plants. Similarly, wind mills and wind turbines are required for the production of wind energy.

A Pollution-free Energy Resource

The energy generated by the combustion of fossil fuels such as petroleum, crude oil, natural gas and coal produces polluting gases and increases global warming. On the other hand, renewable energy does not cause pollution in the atmosphere.

It protects our Earth from catastrophic problems like pollution and global warming, so we need to make every effort to adopt pollution-free renewable energy generated by the sources of renewable energy.

Conclusion

At present, the entire world is largely dependent on sources of non-renewable energy, which is derived from fossil fuels like crude oil and coal. Due to which the fossil fuels are getting depleted rapidly and the oil wells of the oil producing countries are drying up rapidly and the coal mines are also coming to an end. Which is a global concern and the day is not far when fossil fuel reserves will be completely exhausted from the earth. Due to which many activities and economic activities will come to a standstill.

Energy is directly related to the environment. Conventional sources of energy like coal, gas, petroleum, etc. are limited and are very harmful to the environment. On the other hand there are energy options which are reputable and which do not harm the environment. It also avoids global warming and climate change

Conclusion

In conclusion, it can be said that India will quickly achieve an outstanding position in the world in the field of renewable energy and the recent “International Solar Alliance” summit held in New Delhi is a great proof of this. The form of the 21st century is going to be determined without fossil energy.  All over the world, the development and research on carbon-free energy sources have now come out of the lab walls and become industrial and business reality.

Long Essay on Renewable Energy – 5 (600 words)

Introduction

Such energy, which is infinite in nature and freely present, is called renewable energy. In other words, we can say that renewable energy is the energy that we get from those sources, which are available in plenty in nature. Sun, wind, and running water are sources of some energy that will never end, because they are regenerated by nature. All these renewable energies are converted and stored in the form of electricity and transported to us for our use.

Sources of Renewable Energy

Most of the world’s energy is derived from coal, petroleum, natural gas, wind, sunlight, and uranium which are non-renewable resources.

Renewable sources of energy include those sources which, once used, become usable again. Names of renewable energy sources are Sun energy, watermill energy, geothermal energy and biomass (this includes ethanol, biodiesel). According to the data released by the Ministry of New and Renewable Energy, India’s total renewable energy generation capacity is 896602 MW. India has the capacity to generate 900 GW of renewable energy from renewable energy sources such as solar energy, wind energy, hydro energy and bio-energy.

Types of Renewable Energy

Different types of renewable energy are available in this world, which provide clean and sustainable energy for our various needs. Such as wind, sunlight, and ocean are also examples of various renewable energy sources.

At the macro level, we can classify these renewable energies based on their sources.

• Hydropower: Hydropower is the energy that is generated by stopping the flowing water of the river by building dams and driving turbines using its flow. Pumped-storage-hydropower and run-of-river-hydropower are two different ways in which electricity is produced by hydroelectric projects.
• Bio-energy: It originates from biomass bio-energy, which is a renewable energy source for the production of liquid fuels, in which fuel is obtained from the decomposition of various types of agricultural wastes.
• Geothermal Energy: Geothermal energy is a renewable energy that emanates from the heat inside the earth. Geothermal power plants generate electricity by absorbing the energy of earth and hot rocks. Apart from this, geothermal energy can also be used to keep water and buildings warm as per the requirement.
• Solar Energy: This energy is generated by the heat of the sun; solar energy is produced by absorbing sunlight from all types of solar energy resources. Solar energy is a widely used as renewable energy in India.
• Ocean Energy: Ocean energy is also one of the major sources of renewable energy, in which energy can be generated by tidal waves and ocean waves. Although there is no significant development in the field of ocean energy, but because about 70 percent of the Earth is surrounded by oceans, there is a lot of potential for energy production in this area.
• Wind Energy: Wind energy is an excellent example of renewable energy, in which energy is produced by wind. When the wind blows in the wind turbines, renewable energy is generated by its rotational speed. For the manufacture of wind energy, large scale windmills are constructed on the seaside, where the wind blows very fast.

Conclusion

Renewable energy sources are safe, self-sustaining and reliable, with the huge amounts available throughout the year. Also, equal distribution of renewable energy is also possible. There are huge amounts of bio-mass, solar energy, wind energy, biogas and small hydroelectric producing sources in India. We have made considerable progress in the field of solar energy in the last few years, in which it has been widely publicized with the help of the government in the solar energy projects, so now the private companies in this field has also started manufacturing products like solar batteries and solar panels.

We believe that the Three Gorges Dam project will be beneficial to the people of Chinese people and will also increase China’s economic economic contribution to the world economy. The Three Gorges Dam will have a reservoir capacity of 22.15 billion cubic meters, with sufficient reserve to store excess water during floods. By keeping water in the dam, clean water will be accessible to all parts of the country, including those affected by drought, which often do not have enough water to survive. This creates better life opportunities for millions of people. The work associated with the dam’s construction and maintenance, as well as the much larger crops that can be harvested due to the increased amount of water available, will create many more jobs.

Although many say that the dam will far exceed the official cost estimate, and that the money spent will never be recovered, the dam is actually within budget. The dam will also generate 1768 megawatts, producing 84.7 billion kilowatt hours per year. This hydroelectric power is relatively cheap and is cleaner than coal burning, so greenhouse gases will be reduced as well.

This means that more power, one-ninth of all China’s power, will be available locally, for new industry and towns, and that the electricity created will eventually pay for itself. The rapid waters of the Yangtze will be calmed down when the lock system is installed, making shipping faster, cheaper and safer, increasing prosperity.

The dam will also have a positive effect both nationally and internationally. For example, internal trade from Chongqing to Shanghai will increase, which will also increase profitability. Products like coal, oil, silk and agricultural products can be shipped from southwest China to Shanghai and the world, which would amplify China’s standing in the global economy. As the world’s biggest dam, The Three Gorge Dam is being as the “super project” that will prove to the world the Chinese supremacy in the hydroelectric field and will put China on the map as a model developing nation. The Three Gorges Dam Project will not only benefit the workers, but everyone in China, and will help to increase China’s standing in the world and in the global economy.
