Human Development and the Importance of Wind Energy Conversion

With no doubt in mind the wind power plants are safer than most power providing resources. Providing clean energy for the human race and having a positive influence on climate change, the wind power industry is on a rise. With help from the government and with companies becoming more prominent on efficient energy, we could see an even bigger demand for wind power. Environmentally, the wind farms are one of the safest because of the low carbon and emission levels. Continuing are efforts to a safer future, the world is looking into wind farms more and more to help generate enough energy for the human

One of the fastest growing energy sources in the world, wind power is a globally advantageous renewable resource.

In today’s world, there are many different sources of energy that can be used to generate electricity. When you think of the word energy, what comes to mind? For me, I think of having the ability to do wok, whether it is moving an object from one place to another, compressing a gas, producing heat, sound, or light, and having the ability to power something. One very important source of energy that has become very popular in todays world for a means of power generation is wind energy, wind power, or also known as a wind turbine.

Have you ever driven down highway 30 in west central Iowa at night, looked out the window and seen hundreds of red flashing lights? How about driving through north Lincoln and seeing two enormous white turbines spinning in the wind? If you did not know previously, the red flashing lights at night and white turbines are windmills used for generating power. These windmills can produce 2.5 to 3 megawatts of electricity daily. Wind power can be easily used to generate electric for both personal and public use. Looking at the benefits of wind power over fossil fuels, uses of wind power for personal and public use, and the effects of global warming on wind power, you can decide if using wind energy is a good option or not.

Just as there are positive benefits from utilizing this renewable source, there are also some key disadvantages associated with wind energy generation which should be considered. Firstly, the effect of visual impacts depends not only upon the outward appearance of the turbines, but also the individual's personal attitudes to their presence (G.M Shafiullah, 2012). Similarly, a study conducted by Gourlay (2008) showed that the majority of the UK population (approximately 70%) had displayed a positive outlook

We live in a world that is frantically searching for alternative energy sources to reduce our dependence on fossil fuels and offset our negative environmental impacts. In recent years, wind production has presented a very appealing argument in favor of renewable energy. Wind energy is not associated with the typical negative environmental impacts that stem from our traditional energy sources such as air pollution, water pollution, mercury emissions, and climate change (NWCC 1). Wind power’s promise as a clean, free energy source is not the only reason why it has gained modern popularity. Many factors have fueled the wind energy movement. Due to ambitious big wind companies, support from the government and public consent, wind farms have become

Wind energy is a clean, alternative source of energy that does not produce greenhouse gas emissions and can be produced domestically. While wind energy accounts for a small overall portion of the energy produced in the United States, the potential for wind energy is significant. Nevertheless, there are some obstacles that delay the widespread use of this technology, including intermittency of wind, cost, and public policies that deter their implementation.

Everyone knows that the wind is one of the most significant factor of weather and climate because of its role in influencing the distribution of energy and moisture between the parts of the globe. Recently, people have begun to exploit the wind energy which is witnessing the fastest growth in the world. In fact, this source of energy is growing rapidly in all parts of the world. So, most of governments are trying to use wind power for different aspects. In addition, two decades of efforts to achieve technical progress has led to the production of very sophisticated wind turbines which are adjustable, easy and quick to install. Wind power may have many disadvantages, but the advantage of wind energy is more than the disadvantages. So, there are many environmental advantages of wind power such as renewable source, reduction of greenhouse gases, reduction of water consumption, and taking a small space in the land.

“Environmentalists have long argued that renewable energy sources . . . are preferable to fossil fuels,” says H. Sterling Burnett ([1-2]). Environmentalists have long promoted alternative energy sources, especially wind energy. Debra A. Miller says “wind is the most promising alternative source of energy” (56). One author wrote “development of 10% of the wind potential in the 10 windiest U.S. states would provide more than enough energy to displace emissions from the nation’s coal-fired power plants and eliminate the nation’s major source of acid rain” (Kaleen 71). Understanding how the wind is turned into electricity will assist in our comprehending why environmentalists place such value in wind energy. How Is Electricity Generated gives a detailed description of how the wind is converted into electricity. The first step entails the wind turning the blades and generating energy. The second step consists of the spinning blades turning along with the blades. The spinning blades are attached to a hub, and a low-speed shaft that is connected to a gear box that connects to a high-speed shaft. The third step consists of attaching the high-speed shaft connected to an electrical generator to convert the mechanical energy into electricity ([1]). James Taylor says that once electricity has been produced, it is then transmitted to population centers via expensive transmission lines ([2]). With all these supports in favor of using wind energy, environmentalists fail to recognize the

Electricity is a necessary part of our daily lives. Americans rely on it to perform many common tasks, such as cooking food, heating homes, and powering computers. For many years fossil fuels have been the primary energy source, but due to climate change concerns and dwindling supplies it is time to change direction and focus on a new energy source. Other possible energy sources are biomass, geothermal, hydropower, nuclear, and solar, but the most promising source for the future is wind energy because it is renewable, cost-effective, clean, widely available, and good for the

Later, wind energy served mankind by energising his grain grinding mills and water pumps. During its transformation from these crude and heavy devices to today’s efficient and sophisticated machines, the technology went through various phases of development….The earliest documented design of wind mill dates back to 200 B.C. The Persians used wind mills from grinding grains during this period." (Sathyajith Mathew 2)

We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.

Wind turbines make kinetic energy and transform it into mechanical energy. This big device is mainly used at power plants. Turbines can range from small too big. There are

Wind energy is a renewable source of energy, that is harnessed through wind turbines. Wind turbines are placed in wind farms, which consists of multiple wind turbines aligned in a row, that are built in certain locations in order to take advantage of local wind patterns. The use of wind energy can be traced back to Ancient Egypt time. The people would use wind energy to power their sailboats along the Nile River. The first windmills were used in Persia, in the Middle East Region, 1500 years ago. Windmills were mainly used to for drawing water from wells and grinding grain(“Wind Energy.” ). Western Europe later modified it and made the commonly known propeller style with blades made out of blades. Wind turbines today are strong, sleek, and well suited for converting wind into energy. The rotor blades are aerodynamically shaped to make them more efficient. As the rotor blades rotate they convert energy into a rotation energy called torque. The amount of torque produced depends on wind density, wind speed , and the length of the rotor blade. A generator in the wind turbines converts the movement into electricity. Electricity is then sent through power lines. The widely used wind turbines in the U.S. is the GE 1.5 megawatt model. It is a two hundred feet tower with one hundred sixteen blades atop, coming in at a humongous height of three hundred twenty-eight feet(“Wind Energy.” ).
