风力发电的利与弊英语作文

风力发电的利与弊英语作文The Pros and Cons of Wind Power。

In the modern era, as the world seeks cleaner and more sustainable sources of energy, wind power has emerged as a significant contender in the race to combat climate change. Harnessing the power of the wind to generate electricity offers several advantages, yet it also comes with its own set of challenges. This essay explores the advantages and disadvantages of wind power.Advantages of Wind Power:1. Renewable Energy Source:One of the most significant advantages of wind power is that it is a renewable energy source. Unlike traditional fossil fuels such as coal, oil, and natural gas, which are finite resources, wind energy is unlimited and will never run out. As long as the wind blows, electricity can begenerated, making it an essential component of sustainable energy solutions.2. Environmentally Friendly:Wind power is considered environmentally friendly because it does not produce greenhouse gas emissions orother pollutants that contribute to climate change and air pollution. Unlike coal and natural gas power plants, wind turbines do not emit harmful pollutants such as carbon dioxide, sulfur dioxide, or nitrogen oxides. This makeswind power a crucial tool in combating climate change and reducing the harmful impacts of air pollution on public health and the environment.3. Low Operating Costs:Once a wind turbine is installed, the operating costs are relatively low compared to other forms of power generation. Unlike fossil fuel power plants, wind turbines do not require fuel, and the cost of maintenance is minimal. As a result, wind power can provide a stable andpredictable source of electricity at a competitive price, making it an economically viable option for many regions.4. Job Creation:The wind power industry has the potential to create numerous jobs in manufacturing, installation, maintenance, and support services. As demand for wind energy continues to grow, so too will employment opportunities in various sectors of the economy. This can have significant economic benefits for local communities, helping to stimulate economic growth and development.5. Land Use Efficiency:Another advantage of wind power is that it requires relatively little land compared to other forms of power generation. Wind turbines can be installed on agricultural land, providing farmers with an additional source of income without interfering significantly with agricultural activities. Additionally, the land surrounding wind turbines can often still be used for farming or grazing,maximizing land use efficiency.6. Energy Independence:By investing in wind power, countries can reduce their dependence on imported fossil fuels, enhancing energy security and independence. Since wind energy is generated domestically, it reduces the need to rely on foreign sources of energy, thus reducing exposure to geopolitical risks and fluctuations in global energy markets.Disadvantages of Wind Power:1. Intermittent Nature:One of the most significant challenges of wind power is its intermittent nature. Wind is not always predictable or consistent, and electricity generation from wind turbines depends on the availability and strength of the wind. As a result, wind power may not always be available when electricity demand is highest, requiring additional energy storage or backup power sources to ensure a reliableelectricity supply.2. Visual and Noise Impact:Wind turbines, especially when grouped together in wind farms, can have a significant visual and noise impact on the surrounding landscape. Some people find the sight of wind turbines visually unappealing, while others may be bothered by the noise they produce. These aesthetic and noise concerns can lead to opposition to wind power projects, particularly in areas with high population density or scenic beauty.3. Threat to Wildlife:Wind turbines can pose a threat to birds, bats, and other wildlife, especially during migration or in areas with high levels of biodiversity. Collisions with turbine blades and disruption of habitats are among the most significant concerns. To mitigate these risks, careful siting of wind farms and the use of bird and bat deterrent technologies are essential.4. Initial Costs:Although wind power offers low operating costs, the initial investment required for the construction and installation of wind turbines can be significant. The cost of land, materials, and infrastructure can make wind power projects expensive and may deter investment in some cases. However, advancements in technology and economies of scale are helping to reduce these initial costs over time.5. Impact on Radar and Telecommunications:Wind turbines can interfere with radar systems and telecommunications networks, particularly those located near airports or military installations. The rotating blades of wind turbines can create radar reflections and disrupt radar signals, which can be problematic for air traffic control and national defense. Addressing these concerns often requires careful planning and coordination between wind farm developers and relevant authorities.6. Energy Storage Challenges:Energy storage is a significant challenge for wind power. Since the wind does not always blow consistently, excess energy generated during periods of high wind must be stored for use when the wind is calm. While advancements in battery technology and other energy storage solutions are helping to address this challenge, further research and investment are needed to develop cost-effective andefficient energy storage systems.Conclusion:In conclusion, wind power offers numerous advantages as a clean, renewable, and sustainable source of energy. However, it also presents several challenges that must be addressed to realize its full potential. By carefully considering the advantages and disadvantages of wind power and implementing appropriate policies and technologies, societies can maximize the benefits of wind energy while minimizing its drawbacks. With continued investment andinnovation, wind power can play a significant role in the transition to a more sustainable energy future.。

美国风机制造业的分布状况

Exploring the Wind Manufacturing MapAmerica's wind energy industry supports a growing domestic industrial base. Check out this map to find manufacturing facilities in your state.The growth of the wind energy industry in the United States includes an expanding domestic manufacturing base, with 13 facilities that opened in 2010 and an additional 16 in 2011. These and older facilities are visualized by the map above using data collected by the National Renewable Energy Laboratory (NREL). NREL has compiled a list of many of the wind manufacturing facilities in the United States, but there are a number of small component manufacturers that are not included in these data.According to Lawrence Berkeley National Laboratory’s 2011 Wind Technologies Market Report, a dramatic growth in domestic manufacturing has increased the percentage of U.S.-built wind turbines installed in the United States from 35 percent in 2005-2006 to nearly 70 percent in 2011. The American Wind Energy Association estimates that 30,000 American workers are employed at wind manufacturing facilities nationwide – part of the 75,000 total jobs in America’s wind industry.Both U.S. companies and major international manufacturers are investing in U.S. manufacturing and U.S. workers. For example, GE has a parts operations center near Memphis, Tennessee, while Vestas has built a series of turbine blade plants in Colorado.The symbols on the map show what type of manufacturing facility is in each location: “Blades” includes facilities that manufacture the massive fan blades used by wind turbines, with an average diameter of about 89 meters.“Nacelle Components”covers sites that create the internal pieces of the nacelle, or body, of the wind turbine. These include the drive train, cooling systems, andeverything required for generating electricity from wind.“Towers”indicates facilities that exclusively produce the towers used by wind turbines, which have an average height of 81 meters.“Turbines”marks businesses that build whole wind turbines, or assemble the turbines using components from other suppliers.“Other” is a catch-all term that includes manufacturers of tools and equipment used to install and maintain wind turbines, and other industrial components used by the wind industry.This map also illustrates the report’s explanation of where manufacturers choose to place their facilities. Although manufacturing wind turbines is a national industry, many manufacturers choose to place their facilities in the areas of greatest wind power capacity or near other established manufacturers. This map shows installed wind power capacity by state, and the areas of highest installed capacity tend to contain the highest concentrations of manufacturing facilities, as do adjacent states like Michigan or Ohio. According to the report, other considerations, including the availability of a skilled workforce, transportation costs, and state and local incentives for manufacturers, help explain why states that may not have major wind energy resources themselves, such as South Carolina, Georgia, and Alabama, have also seen recent investments in wind turbine and component manufacturing facilities.All the facts and figures used in this article are from the 2011 Wind Technologies Market Report, and more maps and data about the U.S. wind industry can be found at NREL and “Wind Powering America”.美国风机制造业的分布状况王莉编译美国风能行业越来越支持国内工业基地建设。

风能发电项目经济效益分析作者：韩顺行刘广斌来源：《中国经贸》2015年第11期【摘要】我国面临节能和减排的双重压力，发电企业首当其冲。

可再生能源政策要求发电企业必须承担一部分可再生能源发电责任，但总体经济效益如何还不明确。

本文采用项目评价理论方法，结合我国财税政策从宏观层面研究了我国总体风能发电项目预期经济效益，得出现阶段全国总体风能项目经济效益情况。

这一结论的得出，将为相关企业投资风力发电项目提供指导。

【关键词】风能发电折现率；经济效益我国发展可再生能源已经刻不容缓，一方面我国政府承诺到2020年我国碳排放强度较2005年下降40%-50%，另一方面我国能源外部依存度逐年上升，能源安全受到严重威胁。

作为高能耗高排放的发电行业首先受到影响，而可再生能源配额制的即将实施使这种影响落到实处。

风能作为重要的可再生能源之一，风能发电已经在可再生能源发电占比达到71%，但风能项目总体经济效益究竟如何，是否能达到企业预期还是我们现阶段需要解决的问题。

一、项目情况和数据准备1.建设期成本风电场建设期投资成本主要包括风电机组购置成本，接网成本，建设成本，其他成本（安装，技术指导等）。

风力发电项目中风电机组购置成本占比最大，并且风电机组交易存在外部完全竞争市场，因此本文以风电机组购置成本作为计算各项成本投入基准，估算建设期各项成本。

风力发电项目建设、发电、并网等成本由于不同地区自然条件交通状况不同，统计数据来源经常是一种区间，为了保证计算的简洁性和普遍性，本文涉及的区间数据均以平均值代替。

风电机组购置成本=总装机容量×单位装机容量价格风电机组装机容量=风电机组年发电量÷风电机组年利用小时数根据中国电力企业联合会《2012年电力工业统计快报》可知风电机组年平均利用小时为1893小时/年。

2010年中国风力电发电机组平均价格658美元（4154元）/kw，2011年595美元（3755元）/ kw，2012年630（3976元）美元/kw。

Now, use wind power has become the main form of wind, the world's attention, and the fastest.Wind energy technology is a high-tech; it relates more than a dozen of subjects, including meteorology,aerodynamics, structural mechanics, computer technology, electronic control technology,material science,chemistry, electrical engineering, electrical engineering, so the difficulty of a system technology may beyond the difficulty of space technology. First, The division of wind energy technologies:Wind energy technology is divided into large-scale wind power technology and small and medium sized wind power technology, although both are wind energy technology, working principles are the same, the two industries are completely different: specific performance of the "policy orientation is different in different markets, different applications, applied technology is different, totally belong to the same kinds of industries in the two sectors. Therefore, in China machinery industry meeting on the wind to large wind power and wind power to distinguish between small and medium treated separately. In addition, to meet different market needs, extending from the wind and solar technology has not only promoted the development of small wind power technology, but also for the small wind power opens up new markets.1. Large-scale wind power technology:The technology of large-scale wind power in China still has a certain gap between international.The technology of large-scale wind power technology originated in Denmark and some other European countries, the wind power industry propelled by the government, because of the local wind resource-rich,large-scale wind power technology and equipment ahead of the international development. Our government has also started to boost the development of large-scale wind power technology, and a range of policies to guide industry development. Large-scale wind power technology are for the large-scale wind turbine design,wind turbine applications for large area on the very strict environmental requirements are applied to limited resources, wind energy resource-rich wind field, to accept a variety of perennial bad environment that something was the complex nature of the environment, high demands on the technology up on the line.Currently large-scale wind power technology in general is not yet ripe, the core technology of large-scale wind power still rely on foreign, national policy guidance to the domestic wind power project launched in various places, like crazy, all overlook forward to slice. Worthy of the name "mad electricity" through the wind began to Negative effect and Precaution policy. Although wind power projects have been started, but more as complementary type, complete with independent intellectual property rights of large-scale wind power systems technology and core technology few. The test environment needs to have been a large-scale wind power technology to mature. In addition, the large-scale wind power generation technology and network technology has also improved a number of issues still restrict the development of large-scale wind power technology.2. The technology of small wind power:The technology of small wind power in China could compare with the international technology.In 1970s, the small wind power technology in China had been developed which has wind resources for a better situation, including Inner Mongolia, Xinjiang areas, the first small wind power technology is widely used in power transmission project to the Township for a one of farmers and herdsmen household power supply, continuously updated as the technology improvement and development, not only alone but also with the combination of complementary optical has been widely used in distributed independent power supply. These years as Chinese exports of small and medium wind steadily. Internationally, China's small and medium sized wind power technology and wind and solar technology have leapt to international leadership.Small wind power technology is mature and relatively small by natural resource constraints, distributed independent power as a significant effect not only connected, but also the formation of more stable and reliable combination of optical complementary technologies scenery Moreover, technology is completely self-localization. Both from a technical or price in the international arena are very competitive; with international has now started a small wind power in China brand; "wall flower wall Hong" has intensified. In the country's most technical advantages and competitiveness of small and medium wind power has always been forgotten by the government and policy in a corner of reasons, in the early states has been to locate the small and medium sized wind power in Inner Mongolia, Xinjiang, farmers and herdsmen in remote areas to use and return into the agricultural class, low cost, shoddy, low-performance reliability, security, no security of land mostly sparsely populated areas, most of the domestic market are subject to loss of reliability of large price war; in people subconsciously form a poor understanding of So get national attention and development.Domestic small wind power technology in the "low wind start, low wind speed generation, pitch moment, multiple protection, and a series of technical attention by the international market and international clientsunanimously approved, has a leading position. Moreover, the small and medium Wind power technology is ultimately distributed independent power supply to meet end-market, rather than large-scale wind power generation and network technologies to meet the domestic monopoly market, technology, update rate must be adapted to a broad and rapidly growing market.3. wind and solar technology:Wind is the integration of technical skills and the Small and Medium Wind Energy Solar Energy Technology, combines a variety of applications of new technology, and it covers many areas, the wide range of applications, technical differentiation is so great that a variety of techniques which can separate match.Wind and solar power is currently the world in the use of new energy technology the most mature, most large-scale and industrial development of the industry, separate and individual solar wind has its drawbacks of development, but both wind and solar power complementary combined to realize the two new configuration of energy in natural resources, the technical programs of integration, performance and price compared to aspects of the new energy source for the most reasonable, not only reduces the demand to meet under the same unit cost and expand the scope of application of the market, also increases the reliability of the product.In addition: solar and wind power are both new energy, solar energy than the wind started to be late more than 30 per solar PV / W by the general public about the price of recognition can be converted to a 15% rate;while the price of small wind power conversion rate is only 1/5-1/6 of the same 60% -80%, only the low price Worse still suppressed, photoelectric production of pollution on the environment greater than wind power, than substantial development in wind energy, this comparison contrast twist of meditation ......, if people use the energy from the point of view, our goal is to meet the electricity from wind power generating capacity to measure the cost of solar energy economy than many .Wind, solar and wind power integration advantages, not only for the "energy saving, emission reduction,"opened up new horizons for the application of science to meet human needs, for the world to open a fourthRevolution.Second，Wind power has three kinds of operation mode:one is independent operation mode, usually a small wind generators to one or a few families to provide power, storage battery energy, to ensure the electricity without wind, Second is the wind turbines and other power mode (such as engine power), combining to aunit or an village or an island power supply, Three is wind power into conventional power operate and to provide electric power grid, is often a wind tens or hundreds of sets installed wind generators, this is the main development direction of wind power.Wind power system in the two main parts is wind machine and generators. Wind turbines to change from adjusting technique, plasma generator toward VSCF technology, this is the development trend of wind power technology is the core technology nowadays wind turbines. The following simple introduction of this two respects.1 the change of wind plasma from regulationWind turbines impeller, will capture the wind by converting wind effects on the mechanical wheeltorque.Change is the change from adjustment with vertical axis wind leaf surface of Angle, thus affecting the force and the blade, when the wind resistance increases, the output power of the fan is kept constant power output. By regulating mode, fan from the output power curve is smooth. In the rated wind leaf Angle of attack,controller will be placed near zero, do not change, approximate distance equal to adjust for pulp. In the rated wind above, variable structure control function from pulp, adjust the blade Angle of attack, the output power control in near ratings. Change from the wind plasma starting from wind speed is set slurry machine downtime at low impact stress relative ease. The normal work, is mainly adopts power control, in practical applications, power and speed is directly proportional to the set. Small changes will cause the wind changes of wind.Due to the change of wind from pulp by adjusting the impact than other wind from small, can reduce material utilization rate, reduce overall weight. And the change of wind from accommodation type at low speed, can make the blades, keep good Angle of attack than accommodation type stall wind turbines have better energy output, therefore is suitable for low average speed of the region.Change from another advantage of regulation, when the winds reach a certain value, stall type of wind and downtime, must from type machine can gradually changes to the wind load without a blades of open mode, avoid wing, increase of wind turbine.Change is to adjust the defect is sensitive response requires gusts. Because the wind accommodation typestall fan vibration power pulse are small, and accommodation type from wind turbines is bigger, especially for the change from the constant speed windmills way, this kind of circumstance, this does not require more obvious change in the fan is the response speed of wind system to fast enough, can reduce this phenomenon.Third, the development of wind energy technology requires constant innovation:At present, China's wind energy development in technological innovation is still very weak, the lack of core technologies with independent intellectual property. Thus, much would import technology from abroad.Although the arrival of knowledge economy era, all countries take full advantage of global resources and international cooperation through the introduction of technology to bridge the gap and improve competitiveness. But if there is no capability of independent innovation, not know what the introduction of advanced technologies, are not able to absorb the future, can not carry out another record, which is on the one hand; on the other hand, the core technology is the introduction of foreign countries cannot, and must be rely on innovation to master the core technology; Moreover, the domestic policy of independent innovation of technology needs to supporting, guiding, supporting, with the core technology of wind energy products to be increasing support, such a "wall flower wall incense" situation can be change, innovation and power can come from constant innovation.In short: the wind power industry continuing to creating in a single generation from wind energy technology to power the various areas of need ,its additional products have emerged such as: street, landscape, traffic control, communication, irrigation, planting, breeding, sea water desalination , fire, alarm, islands, mountains and so on. Shows the development of wind energy in this new industry can be brought aboutnumerous development and transformation of traditional industries, but the application of wind energy technology in various fields has become the industry's benchmark. World revolution will be caused by wind energy technology from the New Energy and Industrial revolution.风力发电技术风能是非常重要并储量巨大的能源，它安全、清洁、充裕，能提供源源不绝，稳定的能源。

风力发电原理英语作文

风力发电原理英语作文Title: The Principles of Wind Power Generation。

Wind power generation, a renewable energy source, harnesses the kinetic energy of wind to produce electricity. Understanding the principles behind wind power is crucialfor comprehending its significance in the renewable energy landscape.At its core, wind power generation involves the conversion of wind energy into electrical energy throughthe operation of wind turbines. These turbines consist of several key components, including blades, a rotor, a generator, and a tower.Firstly, the blades are designed to capture the kinetic energy present in the wind. Their shape and angle are optimized to maximize the efficiency of this process. Asthe wind blows, it exerts force on the blades, causing them to rotate.Next, the rotating blades turn a rotor connected to a generator. This rotor spins within a magnetic field, inducing an electric current in the generator's coils through electromagnetic induction. The generatedelectricity is then transmitted through cables connected to the turbine and subsequently integrated into the electrical grid for distribution.The height at which a wind turbine is positioned playsa crucial role in its efficiency. Wind speeds tend to increase with altitude due to reduced surface friction, making higher turbine placements more advantageous. Therefore, wind turbines are often installed on tall towers to capitalize on stronger and more consistent winds.Several factors influence the amount of electricity generated by a wind turbine. Wind speed is a primary determinant, as the power output of a turbine increaseswith higher wind speeds. Additionally, the size and designof the turbine, as well as the site's geographical location, terrain, and local weather patterns, all impact itsperformance.One of the key advantages of wind power generation isits sustainability. Unlike fossil fuels, wind energy is abundant and inexhaustible, making it a renewable resource with minimal environmental impact. By harnessing wind power, we can reduce our reliance on non-renewable energy sources and mitigate climate change.Furthermore, wind power is a form of clean energy, asit produces no greenhouse gas emissions or air pollutants during operation. This aspect is particularly crucial in combating global warming and air pollution, contributing to a healthier and more sustainable environment for future generations.However, it's essential to acknowledge the challenges associated with wind power generation. One such challengeis intermittency, as wind is not always predictable or consistent. To address this issue, advancements in energy storage technologies, grid integration, and forecasting methods are continuously being pursued to enhance thereliability and stability of wind power systems.In conclusion, wind power generation harnesses the natural force of wind to produce electricity, offering a sustainable and environmentally friendly alternative to conventional energy sources. By understanding the principles underlying wind power, we can appreciate its role in transitioning towards a cleaner and more sustainable energy future.。

比较潮汐发电和风力发电英语作文

比较潮汐发电和风力发电英语作文Tidal power and wind power are two renewable energy sources that have gained significant attention in recent years as alternatives to traditional fossil fuels. Both technologies harness the power of natural forces to generate electricity, but they have different advantages and limitations. In this essay, we will compare tidal power and wind power in terms of their efficiency, environmental impact, and potential for widespread adoption.Tidal power, also known as tidal energy, harnesses the energy of ocean tides to generate electricity. This is typically done through the use of tidal turbines that are placed in strategic locations where tidal currents are strong. Tidal power has a number of advantages over other forms of renewable energy, including its predictability and reliability. Tidal currents are regular and constant, which means that energy production can be accurately forecasted and planned. Additionally, tidal power is a highly efficient form of energy generation, with some projects boasting efficiency rates of over 80%.On the other hand, wind power utilizes the kinetic energy of the wind to turn turbines and generate electricity. Wind power is one of the most developed forms of renewable energy, with a global capacity of over 600 gigawatts. Wind power has severaladvantages, including its low cost and abundant availability. Wind power is also a clean source of energy, producing no greenhouse gas emissions or air pollutants. However, wind power does have some limitations, including its intermittent nature. Wind is not always constant, which means that energy production can fluctuate depending on weather conditions.In terms of environmental impact, both tidal power and wind power are considered to be relatively low impact forms of energy generation. Tidal power has minimal environmental impact, as it does not produce any emissions or waste products. Tidal turbines can also be designed to minimize harm to marine life and ecosystems. Wind power is also considered to be low impact, but there are some concerns about its effects on birds and bats. Wind turbines can sometimes be a hazard to flying animals, especially in areas with high bird populations.In terms of widespread adoption, wind power has seen much more success than tidal power. Wind farms can be built on land or offshore, and many countries have invested heavily in wind power infrastructure. Wind power is also cost-competitive with traditional forms of energy generation, making it an attractive option for many utilities and governments. Tidal power, on the other hand, is still a relatively new technology with limitedcommercial viability. There are only a handful of operational tidal power projects around the world, and the cost of tidal energy is still higher than that of wind power.In conclusion, both tidal power and wind power have the potential to play a significant role in the transition to a more sustainable energy system. Tidal power has the advantage of predictability and efficiency, while wind power has the advantage of cost-effectiveness and widespread adoption. Both technologies have low environmental impact compared to fossil fuels, making them attractive options for reducing greenhouse gas emissions and combating climate change. As technology continues to improve and costs come down, it is likely that both tidal power and wind power will become more prominent sources of renewable energy in the coming years.。
