Essay on energy: essay examples, topics, questions, thesis statement
Ensure you create essays of professional quality, perfect in all aspects. The world ecological condition is a phenomenon that worries many people around the globe. One of the thesis statement wind energy important issue in the context of an environmental state of the planet is energy sources. There are two main problems related to them.
The first problem is pollution caused by the extraction and using some of the energy sources. The next question is that extraction of some sources has increased dramatically in recent years, which leads to their depletion. In this way, there appeared a necessity to find green and renewable energy sources. Mulugetta and Drake conducted a study of wind potential for Ethiopia, Djibouti, and Eritrea.
Their results indicate the highest potential for wind development along the Eritrean coastline. But none of these studies provided much detail or thesis statement wind energy with regards to the suitability of the wind resource for large-scale development. This study provides a more detailed account of the wind potential in Eritrea and discusses the feasibility of wind power integration at the southern Eritrean port city of Aseb.
To do this, we first define the problem at hand, and then proceed to provide detailed background information on the history, benefits, challenges, economics and technology of wind energy. Eritrea has the potential to incorporate wind power in its energy mix. Since that time, great gains have been made in the efficiency and reliability of wind turbines.
Currently, wind currently contributes less than one percent of electricity production worldwide Gipe but its gross production is rapidly increasing. One factor which inhibits the widespread use of wind power is the difficulty encountered in selecting promising sites. This is because the economics of wind energy development depends sensitively on the nature of the resource.
This thesis statement wind energy that a cheap paper writing large initial investment in studies and investigations needs to be made for wind energy, and that the uncertainties in the wind resource can add an element of risk to wind thesis statement wind energy developments.
There is, however, no thesis statement wind energy model. argumentative essay topics for the scarlet letter wind potential assessments are site specific, they tend to be very thesis statement wind energy consuming and costly. This makes wind power unattractive for most developing countries, whose economic situations force them to find the most inexpensive and expedient means of energy production available.
This thesis hopes to help break down some of these wind energy development barriers for the particular African thesis statement wind energy of Eritrea. We do this by investing thesis statement wind energy and expertise in a more detail, abiet still preliminary, evaluation and analysis of Eritrean wind data. As in introduction to our study, we provide a fairly detailed background on the current status of wind power, and the advantages and disadvantages of wind. We also provide a basic description of wind turbine technology, and wind development economics.
Finally, we discuss thesis statement wind energy energy assessment methods in general before moving on to the country-specific component of our study. History and Current Status of Wind Power In the thesis statement wind energy two decades, utility-scale wind power has been transformed from an expensive thesis statement wind energy energy technology into an economically viable, mature energy option.
Installed wind capacity worldwide has increased from 10 theses statement wind energy in to nearly 5 gigawatts by the end of See palembangpolaroid.000webhostapp.com 1: This thesis statement wind energy growth in thesis statement wind energy capacity was spurred by large reductions in the real cost of wind power.
However, new fossil-fuel technologies have also lowered the cost of new power generated with natural gas or gasified coal. Cost estimates for new combined-cycle natural gas generation are as low as 2. It is important to thesis statement wind energy that the cost estimates given above apply to countries with an installed infrastructure for coal and natural gas, which Eritrea does not have. Furthermore, although fossil-fuel thesis statement wind energy generated with combined cycle technology is less damaging to the thesis statement wind energy than conventional generation from fossil fuels, it is far more damaging than wind power.
Therefore, these costs reflect neither the environmental or public health damage from emissions of carbon dioxide and volatile organic compounds. In addition, wind power decommissioning costs, ultimately paid by society, are low compared to decommissioning costs for other sources, especially nuclear power. Early development of modern utility-scale wind machines occurred primarily in California, spurred by state and federal tax credits and creative writing prompts for first graders for the environment.
Up untilCalifornia still maintained over half of the world’s utility scale wind power. Germany, Denmark, the Netherlands, and the United Kingdom. Recently, a booming market has materialized in Asia, particularly in India, and to a lesser extent, in China. The majority of Asia’s current installed capacity is in India. A number of analysts are concerned that the development in India may be too rapid to ensure that an adequate institutional structure is in place to protect the long term stable development of the industry.
While the European and Asian markets have cover letter bilingual customer service booming, the US market has been declining for several years. This decline has been attributed to various factors including a sharp fall in wind energy purchase prices in California, after the termination of many year power contracts signed in the early ‘s.
These low revenue levels that could not justify new investments, and even made it economically unjustifiable to replace old equipment.
This has resulted in a large number of used and refurbished wind machines being available for relatively low prices. The net effect of the great instability in the California and US markets has been punishing for US wind turbine theses statement wind energy and wind power companies. Although the rapid growth in the European market is expected to slow soon as public objections to wind thesis statement wind energy appearance and noise cardiovascular drugs thesis [Garrad ], the growth in the Asian Market is expected to remain strong.
The number of recent wind energy assessments for lands near the Mediterranean and Red Sea alone suggests growing interest among many smaller energy consumers in the region Radhwan ; Habali et al. Advantages and Disadvantages of Wind Power The theses statement wind energy and technologies required for using wind as an energy source differ considerably from those used in traditional energy sources.
In determining the thesis statement wind energy of the large-scale use of wind energy for a given region, the costs and benefits of the technology must be carefully weighed.
This section discusses the issues that must be taken into account when considering the development of wind as an energy source. We describe qualitatively the factors influencing the costs and benefits of wind power below.
Resource Availability Traditional fuels such as coal and oil, are found only in limited geographical areas. These fuels can be harvested, processed, shipped, essay topics for college texas and used as needed.
This allows production of energy whenever and wherever the demand exists. Good wind resources critical thinking questions 3rd grade math over the earth’s surface than traditional fuels and are essentially inexhaustible.
A major liability, however, is that the resource itself cannot be stored or shipped. After conversion to electricity wind- generated energy can be stored thesis statement wind energy ways. See section on storage, below. Power management and Integration Even in best sites, the wind does not blow continuously.
Although wind power sometimes parallels demand, the correlation is unlikely to be perfect. Large-scale theses statement wind energy at low wind penetration create fewer problems for wind integration than those with higher penetration. If the installed wind capacity is larger than this, then the intermittence problem may be reduced by having many wind turbines spread out among different sites in different wind regimes.
This will smooth the overall output. In addition, if energy demand is not well correlated with the timing of wind supply, financial incentives can be used to shift demand to periods of larger wind power supply. Below this level the supplied energy provides a variable, negative load, and as such reduces the fuel consumption requirements on the other generators in the system. Since wind power is an intermittent energy source, some method of storing energy is desirable for high wind penetration systems to ensure adequate supply during peak thesis statement wind energy.
At present, such storage may be advanced higher english dissertation structure costly for large-scale projects.
Batteries are the simplest method of storing smaller amounts of energy, but these can be large and expensive. Other help to write a personal statement for a job methods include using excess energy to pump water from a low reservoir to a high reservoir during times of low demand, and then allowing the water to flow back down through a turbine to generate electricity when it is needed.
Storing excess energy as compressed air in subterranean chambers has also been shown to be feasible, and may be less costly than storage using the elevation of Business plan to open a car dealership Cavallo, Other possibilities for future utility-scale wind generation include fly-wheel storage for short term variations or chemical energy storage in the form of hydrogen fuels.
The latter may be a particularly promising application for how to write a poem analytical essay wind plants in the long-term future.
Back-up Systems and Additional Power Generation. Another thesis statement wind energy to the intermittence of wind energy is the installation of additional power sources, either as backup systems or to work in conjunction with the wind system. This increased diversity increases system thesis statement wind energy considerably. Consistency is thesis statement wind energy improved through the use of hydropower generators and gas turbines when available.
Because they can be quickly turned on and off in response to wind power fluctuations. Diesel generators can also be run when wind velocity is low and stored electricity is not available, but their response time is not as quick as hydropower and gas turbines. Environmental Issues Compared to most other sources of energy, wind energy is environmentally benign. No air pollutants, radioactive theses statement wind energy or any hazardous theses statement wind energy result from the production or use of thesis statement wind energy turbines.
That is not to say, however, that wind energy does not have any negative qualities. Following is a list of negative environmental impacts commonly associated with wind farms.
Because of the nature of wind, many machines must be installed to intercept a large amount of power. In addition, these machines must be spread out over a large area, to ensure that the turbines do not interfere with each other. Turbines in large thesis statement wind energy farms are typically separated by 5 to 10 thesis statement wind energy diameters, each turbine occupying an area of about 50 square diameters of land. Although these requirements seem demanding at first glance, they actually compare favorably with land requirements for coal or nuclear generation when the full life-cycle requirements of mining, processing, transportation, and waste disposal are considered.
Field studies in California indicate that wind purchase research paper occupy about 7. Using these figures, a wind farm which theses statement wind energy power at the rate of an average nuclear power plant about 1 gigawatt may require an thesis statement wind energy of over 70 square kilometers. Because wind turbines are typically between 30 and 50 meters in height, a significant impact of a large number of turbines in an open area is unavoidable.
Surveys have shown that uniformity of size and thesis statement wind energy improves aesthetic acceptability considerably Clarke, In addition, tolerance of thesis statement wind energy large structures such as pylons, utility towers and telephone poles suggests that negative opinions may be more essay my hero in history allama iqbal matter of habituation than the appearance of the objects involved.
Noise created by gearboxes and blades can be a problem in densely populated areas, and can limit settlement within audible range. This issue has received considerable focus in densely populated Europe where wind development has been very rapid in recent years. Recent studies show that the use of large wind turbines over medium sized turbines limits noise output per thesis statement wind energy, but these large machines have many other drawbacks See Background: Although people do not generally choose to thesis statement wind energy in areas with unusually high wind speeds anyway, care should be taken to ensure a distance of several hundred meters between the turbines and the nearest habitation for both noise and safety reasons.
To avoid problems of interference with vital radio transmission services such as aircraft navigation systems, the relative locations case study in organizational behaviour such facilities and wind turbines should be studied carefully.
Where potential for problems exists, careful choice of turbine design and materials can reduce radio interference. At this point, birds seem to be the only wildlife adversely affected by wind turbines, and even this disturbance is rarely a problem.
Studies show that, in most cases, the effect is negligible under conditions of good visibility. In fact, studies in the United States and Europe indicate that bird deaths attributable to collisions with wind turbine rotors are significantly lower than deaths from collisions with motor vehicles and windows.
At Altamont Pass in California, however, bird strikes occur at a rate of about one per month, which is often enough to raise concerns over the issue. This problem can be limited by avoiding known bird migration routes, and perhaps more importantly, locations of known rare and endangered species. Considerable research is underway on rotor and tower modifications that might be used to limit the disturbance.
When social and environmental costs are included in the price comparison, oil combustion, nuclear fission, and coal are among euthanasia should be legal thesis statement highest cost, whereas efficiency, wind, and biomass are among the lowest-cost technologies See Table 2.
Optimal conditions for the economical development of wind power include high wind speeds, low interest rates, and low labor costs. Due to the high capital costs write my essay for money with wind development, no thesis statement wind energy has successfully built up a thesis statement wind energy generation industry without subsidies. Because wind power is a clean energy source, loan subsidies may be obtained from industrialized countries to help in financing development.
The relatively low cost of decommissioning of a wind power plant is one of its often unaccounted for economic advantages. In addition, the wind decommissioning costs cited here may be overestimated by not taking into account the fact that older turbines can be replaced by modern turbines at the end of their useful lives, reusing the api2017b10.000webhostapp.com and platforms, as well as recycling many of the other parts.
