Economic factors Wind power is cheaper now than most of conventional energy sources and able to rival with new generation of natural gasses due to new innovations in technology. According to U.S. Department of Energy, the cost of wind power in America fell to more than 90 % since 1980, and this is one of the reasons of becoming wind the top source and comprised approximately 45 % of total generation capacity in 2012.”Wind Energy Foundation” .These changes made a huge leap in Renewable energy’s development as lots of businessmen investigate generous contributions. A good example is Warren Buffett’s company that acquired approximately 1 billion wind turbines, the largest industry order to date. On the other hand, each contemporary wind machine, that produces 2 megawatts annually and able to supply the Lilliputian-size village, costs $ 3.5 million. If somebody installs 400 wind turbines which are enough to provide a city, it will cost $ 1.4 billion. Also we have to consider operation and maintenance (O&M) expenses, which have a direct impact on firm’s productivity and competitiveness. ...
College football is one of the most exciting sports organizations in the sporting world. Not only is it thrilling on the field, but also off the field as well. This particular sport organization brings in a ton of money that benefits itself, as well as other sports organizations at the college level. There is a huge demand for success for this organization and if the standard of winning is not there, even for a year, anyone working for that particular school may lose their job. A job I aspire to have is being a college football coach. This job is extremely thrilling as well as displeasing compared to any other job in the organization. The spotlight is not only on the players, but also it is on you as a coach. It is very difficult to keep a job in this organization if as a coach you do not produce a winning record. College football may be the best sports organization to work in and also the worst at the same time.
In “God, Design, and Fine-Tuning”, Robin Collins argues for the Intelligent Design of the universe from the Fine-Tuning Argument. Collins’ argument is probabilistic in nature; however, it fails due to its misuse of probability theory. Aided by the work of both Bradley Monton and Mark Colyvan, I will show why Collins’ argument fails. It can be shown that this line of reasoning concludes that the existence of a life permitting universe is zero. Essentially, Collins’ argument does not prove what he claims it does and is too strong to account for the existence of a life permitting universe because it not only misuses probability, but is rendered useless due to the paradoxes inherent in probability theory.
Pyotr Ilyich Tchaikovsky is widely considered the most popular Russian composer in history, who has added major contributions to the world of music in his time as well as in ours. His most influential as well as prominent works include The Sleeping Beauty and The Nutcracker.
There is physics involved in these wind turbines as they change wind into mechanical energy and then into electricity. The energy produced depends on the volume of the air, the density, and the wind speed. The mass per unit time is the mass times the density times the wind speed or m = mass, p = density, A = area, and v = wind speed; m = pAV. Because the function of the wind turbine is to transform the wind’s kinetic energy into electricity the equation for kinetic energy is needed; KE = ½ mv2 or kinetic energy equals one half the mass times the velocity squared. Then, using substitution, the power in the wind depends on the density of the air, area swept out by rotors, and the cube of the velocity or ½ pAV3. Using Betz’ law the theoretical energy model for extracting 59% of the energy is power = 16/27(½ pAV3) .
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.
Ignorance is a characteristic that has befallen many great political leaders. With this characteristic many leaders have lost their power, through a disaster or simply not enough people voted for him/her. Although many key characters in Julius Caesar are in their own way all sensible, a majority of them do not consider their peer’s opinion, displaying ignorance which creates their own demise caused by their own ignorance.
“Do not judge me by my successes, judge me by how many times I fell down and got back up again.” – Nelson Mandela. The quote by Nelson Mandela, sums up my personality,← a better way to say this? Explains the type of person I am? I am persistent. I do not give up, and I am determined to succeed in my academics. I have overcome a lot of struggles throughout the undergraduate years. Which lead to my falling, but over the years I picked myself back up and showed that I am able to succeed with my degree in Sociology. ***←- how can I show this without saying I am determined to succeed.
In the words of writer Richard Whately, “It is the neglect of timely repair that makes rebuilding necessary”. However, to the owners of broken ceramics living in 19th century Japan, the process of timely repair is no longer an option. Nevertheless, the restoration process of kintsugi is an alternative to broken ceramics. We cannot know for certain whether the owners of our piece were of means or skilled artisans themselves, but we do know the same process was used to restore the ceramic this paper will try to focus on. The piece shown in figure 1, being a doubtless example, has a larger story to tell than the fact that it was mended. The special characteristics that make it stand out from the hoard of other ceramics would be the radical changes in Japanese society in the 19th century when this piece was restored, the poetic origins of the decorations, and how the entire process of kintsugi reflect the mentality of the artisans. Of course, if we consider the entire wide pool of ceramics there is bound to be a piece similar to this, however, the fact that this piece is well intact and how well it represents 19th century Japan is worth our attention.
First and foremost, unlike power plants that rely on combustion of fossil fuels, wind turbines do not produce atmospheric emissions. Strangely enough, wind is a form of solar energy. Winds are caused by the irregular heating of the atmosphere by the sun, the variations of the earth 's surface, and rotation of the earth. This wind flow, or kinetic energy, when "harvested" by modern wind turbines, can be used to generate electricity. There is an abundance of wind to meet our needs, “the potential of [the total] wind power [in the world] is… 20 times more than what the entire human population needs” (Maehlum). Currently, wind power is one of the lowest-priced renewable energy technologies available, costing between four and six cents per kilowatt-hour, depending upon the wind
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.
