...WIND ENERGY I. Concept: _ Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unevenly heats the surface of the Earth. As hot air rises, cooler air moves in to fill the void. As long as the sun shines, the wind will blow. And as long as the wind blows, people will harness it to power their lives. _ The terms "wind energy" or "wind power" describe the process by which the wind is used to generate mechanical power or electricity. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity to power homes, businesses, schools, and the like. II. Operating principle: _ Wind power is extracted from air flow using wind turbines or sails to produce mechanical or electrical power. Ancient mariners used sails to capture the wind and explore the world. Farmers once used windmills to grind their grains and pump water. Today, more and more people are using wind turbines to wring electricity from the breeze. Over the past decade, wind turbine use has increased at more than 25 percent a year. _ Most wind energy comes from turbines that can be as tall as a 20-story building and have three 200-foot-long (60-meter-long) blades. These contraptions look like giant airplane propellers on a stick. The wind spins the blades, which turn a shaft connected to a generator that produces electricity. Other turbines work the...

...Should the global super powers lead an effective way in developing renewable energy? Global super powers rely heavily on energy, so therefore they should develop and fund renewable energy sources. Small countries have a smaller need. They do not have as much capital, so they rely on the global superpowers. Renewable energy is the cleanest way to keep earth clean and free of pollution. Global powers have the resource to advance renewable energy quickly. They have professional people, machinery, technology, money know-how, etc. to make things happen. Different countries in different parts of the world use different kinds of renewable energy. Countries can share with other countries what they’ve learned. This is an effective way to increase renewable energy. The population of the world will greatly benefit from renewable energy. People will be healthier and pollution will be greatly decreased. There will be an ongoing supply of power for every facet of life. Renewable energy must be developed because nonrenewable energy is becoming expensive and environmentally damaging to retrieve. Renewable resources are constantly replenished and will never run out. A clean energy revolution is taking place among global super powers. This generates hundreds of billions in economic activity, and is expected to continue to grow rapidly in the coming years. This...

...results. An organization may choose to implement one plan or several incentive plans operating at once leaving employee’s to choose plans to pursue based on their individual goals. Despite the fact that all organizations would like to keep a staff that is highly motivated and productive it is not always possible to implement some of the plans based on factors that may be out of the organization’s control. For example, a non profit organization would find it impossible to implement a profit sharing plan. The selection of the incentive plan to use is dependent on the type of business among other factors and if properly implemented can provide a major boost to the organization. In this paper we will highlight the incentive plans at Pratt nursing home. We will attempt to understand why the incentive plans in place assist the organization in achieving objectives. We will also describe how we believe they are related to organizational goals and objectives. We Incentive Plan 2 will make reference to current examples in the public domain to stress our arguments. We...

...On October19, 1941 at approximately 6:56 pm a spinning two blade wind turbine began producing power on a hilltop known as Grandpas Knob in the town of West Rutland Vermont. This turbine ran for approximately 3.5 years, suffering numerous malfunctions and shutdowns. The project was abandoned in the spring of 1945 after one of the apparatus’s eight ton blades snapped off and crashing to the ground. While impressions on a whole deemed this pioneering experiment in wind power production a failure, the mountain top itself was spared from any massive destruction from this small scale wind project. Now Sixty-seven years later, a new generation of wind power turbines is being considered at this very same site and the surrounding area. Although this newly proposed wind farm along six miles of ridgeline is estimated to produce 50 megawatts of electricity and provide enough power for 15,000 households, this project will result in the irreversible destruction of this mountain top ecosystem. The environmental costs greatly outweigh any financial benefits that this proposed project offers. Background In early 2007 a renewable energy company named Noble power, a company that specialized in wind turbine construction, met with local officials to float the idea of a wind park on the Pittsford ridgeline known as Grandpa’s Knob. Noble ran into financial problems as a result of the 2008 recession and was forced to close its Rutland office in January 2009.Another event happened in 2008 when Vermont...

...produce enough energy that we would never have to use fossil fuels again. Alternative energy is the use of other energy sources instead of the use of fossil fuels or nuclear energy. Solar power can be used to operate cars and provide electricity to homes and businesses. Hydropower can be used to provide electric power to small towns and cities. Geothermal power can heat up buildings or water to power turbines to make energy. Wind power can be used to pump water and generate electricity. So let’s start with solar power since it is the most known of the group. Energy from the sun is one of the most abundant resources available today out of the alternative group. It is one of the most important of the non-conventional energy sources as well, because it does not pollute the earth. “One of the reasons for this is that the total energy we receive each year from the sun is around 35,000 times the total energy used by man”. (Alternative Energy Sources) One way to capture the sun’s energy is through the use of solar panels made out of Photovoltaic cells, which are commonly called (PV) cells. These panels can be used on homes, businesses, greenhouses, water heaters, traffic lights, or grouped together as a solar power plant. PV cells can transform the sun’s energy directly into electricity. Since solar power plants generate no air pollution during operation, the primary environmental, and safety issues involve how they are manufactured, installed, and disposed of. Since energy is needed to...

...Energy sources are used as fuels. Fuel is burned in machinery to create motion that we use in our cars or heat in a home energy system. When fuels are used for producing electricity, heat or motion causes a generator to rotate, creating electricity for everyday use in homes and businesses. Energy sources can be classified into two types: nonrenewable and renewable. Nonrenewable resources, such as fossil fuels and nuclear material. Fossil fuels were formed from the fossilized remains of tiny plants and animals that lived long ago. Most electricity used in the world is generated from power plants that burn fossil fuels to heat water and make steam. The highly pressurized steam is directed at turbine blades to make them spin. Nonrenewable resources cannot be replenished. We have limited supplies of them, and when these supplies are gone we will not have any more. These resources have been the most used type of energy in the modern era. Renewable resources, such as wind, water, solar, and geothermal, come from sources that regenerate as fast as they are consumed and are continuously available. Renewable energy resources can be replenished in a short period of time, so they will never be all used up. Some, such as biofuel produced from food crops and other plants, are replenished every growing season. In the early part of the twenty-first century, renewable sources have become more popular as nonrenewable sources have begun to be depleted. Energy companies around the country are...

...Waste and Energy Paper Team A ENV 100 February 13, 2012 Instructor - Onesimus Otieno Waste and Energy Paper Oil is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. Oil is then refined and separated into different products – such as gases, jet fuel, heating oil, diesel, and asphalt. Oil is also used to make petrochemicals, compounds used to make products such as fertilizers, plastics, paints, pesticides, medicines, and synthetic fibers (Berg & Hager, 2009). Most environmental problems associated with oil are caused by burning and transporting it. Burning oil produces carbon dioxide, which is a greenhouse gas, so it contributes to global warming. It can also lead to acid deposition because the combustion of oil is the leading cause of nitrogen oxides. Nitrogen oxides inhibit plant growth and they are involved in photochemical smog and acid deposition (Berg & Hager, 2009). They can also lead to acidification of soils, affecting the plant varieties that are able to grow in the soil. This leads to a decrease of diversity in the environment. Plants that cannot handle acidic soils die off. In turn, animal species in the area decrease as only the species that can live off of those particular plants will thrive. Others will move on to new areas looking for plants that they have become accustomed to. Another...

... and of course technology. Green Technology is becoming so widespread throughout the world. People are becoming more energy efficient in their homes by buying water-efficient showerheads that are low-flow models, adjusting their refrigerator and freezer temperatures, buying compact fluorescent light bulbs, buying energy efficient appliances, and by recycling rechargeable devices like cell phones or digital cameras. As awareness grows about environmental issues such as pollution, human impact on climate change, and depletion of natural resources, so is interest growing in environmentally friendly products and services. For example, the popularity of green cleaning products has increased in recent years. Nontoxic, biodegradable cleaning products are safer for use in the home meaning they are less likely to cause health problems. They also keep harmful chemicals out of the environment. Compact fluorescent light bulbs (CFLs) are another popular eco-friendly product; compared to traditional, incandescent light bulbs, CFLs use way less electricity. Here are a four of the many types of green technology used today; green energy, vehicles, building and appliances. Green energy as of today is produced by these forms of energy; solar, wind, and hydroelectric power. Solar power or solar energy is a technology that converts the power of the sun into usable energy. It is a resource that cannot be used up by us using it. Much of the world's...

...WORLD ENERGY OVERVIEW Most countries have set high goals for the utilization of renewable energy by the middle of the century, but present day usage of alternative sources of energy is dominated by the developed nations such as the United States, Germany, Spain and Denmark, with Brazil and China leading the leading nations. * Cause of using Possible Alternative Energy all over the World: * It does not seem quite sensible to keep on utilizing the same dirty sources of energy every time, and also keep worrying about them running out. If we think over this, we will come as funny. If we could tame the energy of the water, wind and the sun, we would be living in a world that had an inexhaustible and infinite source of energy. In addition to all these, the energy obtained would also be clean. Also, there would be no potential risks for the environment, and we could live in a world that would be completely free from any detrimental impact on the environment. It is our call to keep the pollution under check, since it is us who ever started the pollution in the first place. The technology that we created earlier was intended to make the energy sources we have now work for us. It is therefore now our responsibility to take proper care of the ecosystem. * The technology that is essential for the utilization of the alternative sources of energy has become quite affordable in these times. This is because more and more number of people is now using it. And for those who...

...Revolution John C. Ayers "In a sense, the fossil fuels are a one-time gift that lifted us up from subsistence agriculture and should eventually lead us to a future based on renewable resources." Kenneth Deffeyes (2001) "I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that." — Thomas Edison, 1931 We cannot create or destroy energy. We can only capture it. The sun provides either directly or indirectly nearly all of the energy available to us. Plants capture solar energy directly through photosynthesis. Fossil fuels contain the energy of sunlight captured hundreds of millions of years ago. Photovoltaic (PV) cells also capture sunlight energy directly. Other energy sources capture the energy of sunlight indirectly. Heat from the sun powers the flowing air and water. We usually capture the kinetic energy of wind and water by using turbines that transfer the energy to an alternator, an electrical generator that produces alternating current. Geothermal energy is different in that it captures flowing heat energy produced by radioactive decay in the earth’s interior. In this chapter we will see that Wind, Water, and Sun (WWS) energy sources are sustainable because they are renewable, clean, safe, and nearly carbon-free. Although they have low energy densities, meaning that they require large areas of land or water to produce energy, they are sufficient to meet the energy needs of the US...

...The Big Wind MGT-541 Advanced Marketing Management March 16, 2012 The Big Wind 1. What type of research should Urs do? Urs has many different issues that she is facing in making this windmill decision. Urs must first conduct market research. Market research has a variety of purposes and a variety of data collection methods that can be utilized for each purpose. What Urs needs to understand is that no small business can succeed without understanding who the potential customers might be, how those products and services affect the customers, and the market in general. Competition is often fierce, and operating without conducting research may give competitors an advantage. There are two ways to do market research, primary and secondary research. ("Market Research," 2010) As a general rule, a thorough research of the secondary data should be undertaken prior to conducting primary research. Using information gleaned from secondary sources, the owner can uncover all kinds of demographic information, including detailed income data and spending patterns. The secondary information will provide a useful background and will identify key questions and issues that will need to be addressed by the primary research. Performing secondary market research means obtaining information from sources such as trade journals and magazines where published papers, directories and even market statistics can be found. Useful qualitative...

...converted to useful forms by various means. Energy and its conversion between forms can be expressed quantitatively. When converting energy, a significant fraction of that energy can be lost from the system (in the form of heat, sound, vibration, etc.) For example: in a power plant burning coal will produce heat energy, heat energy transfers to the water causing water to turn into steam, steam move the turbine due to pressure, energy is now transfer from heat to mechanical energy, then mechanical energy is converted to electrical by the generators, here we have a good example of energy converted to another form. Another example: leave a stone from a certain height and it will fall straight down. all the potential energy has been converted into kinetic energy. (YahooAnswers.com, 2012). Define what we mean by fossil fuels and explain why there an attractive source of energy. Fossil fuel consists of the remains of organisms preserved in rocks in the earth's crust with high carbon and hydrogen content. They are attractive because they are or were, readily available, can be easily transported and can be refined to several grades of usable fuels such as gasoline, diesel fuels, jet fuels, and natural gas for home and commercial use. (ChaCha Search, Inc.2012). Gasoline and diesel have long been the predominant vehicle fuels in the United States, but today, concerns ranging from greenhouse gas emissions to energy security are spawning new interest in other sources of energy...

...I use a lot of is electrical energy. We use this energy for basically everything that we come in contact with; cell phone chargers, laptops, television, lamps, refrigerators and even your car’s battery. Even though you will always use this energy every day, the amount of the energy can vary. In 12 days we will be turning our clocks for daylight savings, and in this case this is help us save on energy because it will stay daylight out longer so you will not need to turn on the lights so early. Another way energy usage can change is with the seasons. When it starts to become colder in October, you are going to start to turn your heat up a little more. As it continues into the winter months you are going to use more gas and electricity to power your house. When the time of daylight savings start to approach, a whole new type of energy is going to be used. In the summers months starting around June, people are going to...

... transportation, lighting, heating and cooling homes, and manufacturing. Because of the limited amount of non-renewable energy sources, it is important to conserve our current supply or to use renewable energy sources so that our natural resources will be available for future generations. Renewable energy is natural resources such as sunlight, wind, water, and geothermal heat, which are naturally replenished. Renewable energy technologies range from solar power, wind power, hydroelectricity, biomass, and bio-fuels. Non-renewable energy sources are oil, natural gas, and coal. Non-renewable energy is energy taken from resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. Non-renewable energy cannot be replenished in a short period of time. In this paper I will discuss what energy resources we currently rely on for everyday use, what impacts have been observed on both humans and the environment as a result of increasing energy needs and usage, what new energy resource is best for your home and how can a few simple changes can make a big impact on our environment. Energy Resources for Everyday Use There are many energy resources that we rely on everyday that we do not even think about until we do not have them or the cost of them go up. One is Petroleum. Petroleum is a fossil fuel that we as Americans use every day. We use it to fuel our vehicles and heat our homes. A couple of years ago the cost of petroleum went...

...Examining My Communities Source Of Energy Aaron L. Hunt Argosy University July 11, 2014 Electricity, natural gas and solar energy are the three primary types of energy used in my community. Electricity is the only type of energy I use in my home. Dealing with any energy source, you are bound to have some type of negative impact on the environment. For example, the use of fossil fuels to create electricity omits dust, soot and other materials that are released into the atmosphere. In addition, the same solid materials along with chemicals that naturally occur in the atmosphere, assists in creating acid rain and negatively affecting my community. Pensacola, Florida deals with a low level amount of nuclear waste. Radioactive waste resulting from a nuclear medicine treatment, medical equipment that uses radioactive isotopes and cancer therapies are the extent of nuclear waste disposal in my community. , however, like many communities we dispose of toxic and hazardous wastes such as electronics, industrial waste and asbestos. Electricity and gas has been the two main energy sources for many years in my community. The demand for electricity is constantly growing with the expansion of my community so companies are attempting to generate electrical energies from The Straits of Florida. The installation of EPUs or Electrical Production Units can potentially damage sensitive coastal marine environments and are hazards to migrating mammals and fish. (Finkl, Charlier & Makowski...
