Using Wind Power as an Alternative Energy
Energy is the ability to do work. It surrounds us in all aspect of life. However, the ability to harness it and use it, as economically as possible, is the challenge before mankind. Alternative energy refers to energy sources, which are not based on the burning of fossil fuels or the splitting of atoms. The renewed interest in this field of study comes from the undesirable effects of pollution both from burning fossil fuels and nuclear waste by products. Fortunately, there are many means of harnessing energy that have less damaging impacts on the environment. One example wind power. Wind energy is a clean and renewable source of electric power and is also the world's fastest growing energy source.
More then five thousands years ago, the Egyptians used the wind to sail ships on the Nile. Later, people built the first turbines and used the wind to grind grain. These machines looked like paddle wheels and were used in Persia as early as 200 BC. By the fourteenth century, the Dutch had taken the lead in improving the design of windmills. They invented propeller type blades and used wind power to drain the marshes and lakes of the Rhone River delta. In America, Early European settlers used windmills to grind wheat and corn, to pump water, and to cut wood at sawmills. By the early twentieth century, small windmills were used for pumping water and electric power generation in Europe, the United States, Africa, and elsewhere. In addition to thousand of small wind electric generators, a few larger systems were built in North America and Europe.
In the 1970's, the increase in oil and fossil fuel prices helped wind power return as an economical alternative energy source. Governments all aroun...

Wind power has an expansive future according to experts. In the 1990's wind energy was the fastest growing source of electricity in the world. However, the majority of this growth has been in Europe. This is where government policies and high conventional energy costs favor the use of wind energy. The U.S. Department of energy recently announced that it hopes to power at least 5% of the nation's electricity with wind by 2020. The department also wants to increase federal use of wind energy to 5% by 2010.
Although the world may never be able to fulfill all of its energy needs through renewable energy sources, it is a goal worth trying to achieve. And people are working toward that goal. Many advances in the field of wind generated power have been made in recent years, and research efforts continue to press forward on numerous other alternative energy fronts.
With concern over global warming growing, people are starting to turn a more serious eye toward cleaner sources of energy. Instead of solar power making a comeback as the ideal form, we are seeing a growth in the use of wind power. Wind farms are beginning to crop up all around the country. This new trend has gathered significant attention. Questions are being raised concerning the effects wind farms may have, from critics and supporters alike. Michelle Nijhuis, in the article “Selling the Wind” discusses the arguments on behalf of and in opposition to the increasing use of wind power, addressing what the consequences may be on the United States.
2. Personally i am for wind farms and in my opinion. I think that wind energy has a great potential not only is wind energy very reliable and sustainable. it is also not as expensive as some at the other types of renewable green energy sources.
I personally do not like windy days. However, wind could be helping us more than we realize. We could be using the wind to produce energy. This is what wind turbines do and now I will be researching them to determine the physics involved with them and how they work, their history, along with some statistics from the United States. Then I will go in-depth for the wind turbines of Texas, Washington, and Kansas and compare them.
As time would go by many people had hard time doing many things due to the fact that they took really long to either finish or create. People were finding alternative ways of making life much easier for people, these were called scientists. Ideas to creating new things were being shared in scripts and these ideas were spread throughout Europe. One of the top man made invention was the vertical windmill. This windmill would help grind grain and some even pumped salt water for salt making. These machine only worked when one force was applied to it, wind. Wind would be the biggest source energy during the medieval time since electricity wasn’t yet being used. Other than the windmill the watermill was a great invention as well. Watermills were applied to boats to help move in water a quicker than just rowing. These mills had to be improved from the ancient manuscript due to the bad translations by others through centuries. Another invention that would be used would be the mechanical clock. The clock wo...
Alternative energy sources are renewable, and are most commonly referred to as free energy sources. There are many alternative energy sources such as hydro power, solar power, wind, biomass, and geothermal. Using alternative sources is more expensive in the long run, but it is the much safer option for our environment compared to fossil fuels. Although everything used is completely free, such as water and wind, the equipment used to generate these things is expensive. There are several pros and cons that come with the utilization of alternative energy sources.
Morality is the principle concerning the distinction between right and wrong, or good and bad behavior. The book “To Kill A Mockingbird,” displays a number of characters who are willing to do the right thing morally, but also a lot who won’t. Of those characters who won't, the one worst is Bob Ewell, the main antagonist of the novel. He is known as a drunkard and abuser who is despised throughout the community and even his own family. Bob Ewell falsely accuses black man, Tom Robinson, of “raping his daughter,” Mayella Violet Ewell.
In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.
Wind Energy is a viable industry that has become a valuable energy source. The energy generated from wind is clean and efficient. The wind energy industry helps to ensure that electric demands are met, wildlife impact is minimal, the environment is not devastated, as well as creates new jobs during the construction of wind farms, daily operations, manufacturing components, and exporting components to foreign countries.
Wind turbines are a great source of energy around the world. Wind turbines produce wind energy that can be used to power our homes. Wind turbines convert kinetic energy into mechanical power. Then this mechanical power gets generated into electricity. Wind turbines make energy by the wind turning the large blades, which spin a shaft that is connected to the large blades, which then operates the generator making electricity.
In the search for alternatives to fossil fuels, scientists and policy makers have focused on three options: nuclear power, energy from biomass; and a combination of wind, water, and solar power. Nuclear power, however, is much more costly and runs the risk of having it fall into the wrong hands where it could be turned into a weapon of mass destruction. The third option entails wind turbines, photovoltaic power plants and rooftop systems, concentrated solar thermal power plants,...
Understanding the environment would help you recognise the appropriate energy production system to use. Renewable energy is an alternative natural source to fossil fuels like sunlight, wind and geothermal heat. Wind turbines and photovoltaic panels are examples of energy production systems where the conditions of a particular environment has to be taken into account. If a building is located alongside or near
For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
Wind power is one of the most sustainable ways of generating electricity as no toxic emissions are produced; it does not add to global warming and is one of the most available sources of renewable energy and theoretically it is an infinite source of energy. On sufficiently windy areas, wind turbines are one of the most economical methods of generating electricity, which makes it appealing to many individuals, governments and organizations. Due to this it is the fastest growing source of electricity in the world (Union of Concerned Scientists, 2014) with a 10% increase in yearly additions installed in 2012 compared with 2011 (Global Wind Energy Council, 2012). However the proportion of energy that can be harnessed through wind power is restricted by the cost of the infrastructure needed, construction, the amount of wind that occurs and that there are only a narrow number of sites within the UK that are windy enough for the wind turbines to be worth installing.
Wind is a form of solar energy. The term wind energy describes the process by which the wind is used to generate electricity or mechanical power. Wind turbines convert mechanical energy from the wind into electrical power. Wind turbines usually have three main parts. There are blades that connect to a central hub, a box behind the blades that contains the generator, and a long stem that connects to the ground. The way how it works is that the wind turns the blades, which spins a shaft that connects to a generator making electricity. After the electricity is produced it is sent through transmission lines to a substation that is sent to business and homes. For the sake of our planet, we must promote a renewable energy economy. Wind power can be a foundation of that sustainable energy future because it provides jobs in states that are building wind turbines, is a renewable energy source, and does not damage our environment. The environment will not be damaged by the pollution, the natural resources will not be used up, and there won’t be generating of hazardous wastes. Welcoming wind energy today will lay the foundation for a healthy tomorrow that will affect everyone in the United States. There are obstacles and challenges that will make it more difficult, but the environmental impact is well worth it to invest more money into wind energy.
