solar energy(英语简介)
太阳能英语知识点总结
太阳能英语知识点总结History of Solar EnergyThe use of solar energy dates back to ancient times when people used magnifying glasses to concentrate sunlight to light fires. The first recorded use of solar power was in the 7th century BC when mirrors were used to concentrate sunlight to light torches. In the 3rd century BC, the Greeks and Romans used passive solar design to heat their homes and bathhouses.The modern era of solar energy began in the 19th century with the development of solar cells by French physicist Alexandre-Edmond Becquerel. In 1954, Bell Laboratories invented the first silicon solar cell, which was the precursor to today's photovoltaic cells. Since then, solar energy technology has advanced significantly, making it an increasingly viable and accessible energy source.Technology of Solar EnergyThere are two main technologies for harnessing solar energy: photovoltaic (PV) and concentrated solar power (CSP).Photovoltaic Technology: Photovoltaic cells, commonly known as solar cells, convert sunlight directly into electricity. When sunlight strikes the semiconductor material in the solar cell, it creates an electrical current. Solar panels consist of multiple solar cells connected together to form an array. The electricity generated by the solar panels can be used directly or stored in batteries for later use.Concentrated Solar Power Technology: Concentrated solar power uses mirrors or lenses to concentrate sunlight onto a small area, which generates heat that can be used to produce electricity. The concentrated sunlight heats a fluid, such as water or molten salt, which then produces steam to drive a turbine and generate electricity.Benefits of Solar Energy1. Renewable and Sustainable: Solar energy is an abundant and inexhaustible source of energy. The sun has been shining for billions of years and is expected to continue shining for billions more, making solar energy a sustainable and reliable source of power.2. Environmentally Friendly: Solar energy produces no greenhouse gas emissions or air pollutants and has minimal impact on the environment. By using solar energy, we can reduce our reliance on fossil fuels and mitigate the effects of climate change.3. Energy Independence: Solar energy provides a decentralized source of power, allowing individuals, businesses, and communities to generate their own electricity and reduce their dependence on the grid.4. Cost-Effective: The cost of solar panels and related technologies has decreased significantly in recent years, making solar energy more affordable and accessible. In many regions, solar energy is now cost-competitive with traditional sources of energy.Challenges of Solar EnergyDespite its numerous benefits, solar energy also faces several challenges that hinder its widespread adoption and use.1. Intermittency: Solar energy is dependent on sunlight, which is not constant and varies with weather and time of day. As a result, solar energy production can be intermittent and unreliable, requiring energy storage or backup power sources.2. Land Use: Large-scale solar farms require a significant amount of land, which can be a challenge in densely populated areas or environments with competing land uses.3. Energy Storage: Energy storage technologies, such as batteries, are necessary to store excess solar energy for use during periods of low sunlight. However, current energy storage solutions are expensive and limited in capacity.4. Resource Limitations: The production of solar panels and related technologies requires raw materials, such as silicon, silver, and cadmium, which are limited in availability and can have environmental impacts.Future Prospects of Solar EnergyDespite its challenges, the future of solar energy looks promising. The ongoing advancements in solar technology, such as the development of more efficient solar cells and energy storage systems, will continue to drive down the cost of solar energy and increase its accessibility.In addition, the increasing awareness of climate change and the need for sustainable energy solutions has catalyzed a global shift towards renewable energy, with solar energy playing a leading role in this transition.Furthermore, government incentives, policies, and regulations aimed at promoting renewable energy and reducing carbon emissions are driving investment in solar energy and spurring the development of large-scale solar projects.ConclusionSolar energy is a clean, renewable, and sustainable source of power that has the potential to revolutionize the way we produce and consume electricity. With ongoing technological advancements, decreasing costs, and increasing environmental concerns, solar energy is poised to play a key role in our transition to a more sustainable and low-carbon future. As we continue to harness the power of the sun, it is important to address the challenges andlimitations of solar energy to realize its full potential and maximize its benefits for generations to come.。

Solar energySolar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used.Solar powerSolar power is the generation of electricity from sunlight. This can be direct as with photovoltaics (PV), or indirect as with concentrating solar power (CSP), where the sun's energy is focused to boil water which is then used to provide power. Solar power has the potential to provide over 1,000 times total world energy consumption in 2008, though it provided only 0.02% of the total that year. If it continues to double in use every two to three years, or less, it would become the dominant energy source this century. The largest solar power plants, like the 354 MW SEGS, are concentrating solar thermal plants, but recently multi-megawatt photovoltaic plants have been built. Completed in 2008, the 46 MW Moura photovoltaic power station in Portugal and the 40 MW Waldpolenz Solar Park in Germany are characteristic of the trend toward larger photovoltaic power stations.Much larger ones are proposed, such as the 100 MW Fort Peck Solar Farm, the 550 MW Topaz Solar Farm, and the 600 MW Rancho Cielo Solar Farm.Solar power is amazing. On average, every square meter of Earth's surface receives 164 watts of solar energy. In other words, you could stand a really powerful (150 watt) table lamp on every square meter of Earth's surface and light up the whole planet with the Sun's energy! Or, to put it another way, if we covered just one percent of the Sahara desert with solar panels, we could generate enough electricity to power the whole world. That's the good thing about solar power: there's an awful lot of it—much more than we could ever use.But there's a downside too. The energy the Sun sends out arrives on Earth as a mixture of light and heat. Both of these are incredibly important—the light makes plants grow, providing us with food, while the heat keeps us warm enough to survive—but we can't use either the Sun's light or heat directly to run a television or a car. We have to find some way of converting solar energy into other forms of energy we can use more easily, such as electricity. And that's exactly what solar panels do.Solar cellA solar cell is a device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight such as solar panels and solar cells, while the term photovoltaic cell is used when the light source is unspecified. Assemblies of cells are used to make solar panels, solar modules, or photovoltaic arrays. Photovoltaics is the field of technology andresearch related to the application of solar cells in producing electricity for practical use. The energy generated this way is an example of solar energy.History of solar cellsThe development of the solar cell stems from the work of the French physicist Antoine-César Becquerel in 1839. Becquerel discovered the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution; he observed that voltage developed when light fell upon the electrode. About 50 years later, Charles Fritts constructed the first true solar cells using junctions formed by coating the semiconductor selenium with an ultrathin, nearly transparent layer of gold. Fritts's devices were very inefficient, transforming less than 1 percent of the absorbed light into electrical energy.By 1927 another metalÐsemiconductor-junction solar cell, in this case made of copper and the semiconductor copper oxide, had been demonstrated. By the 1930s both the selenium cell and the copper oxide cell were being employed in light-sensitive devices, such as photometers, for use in photography. These early solar cells, however, still had energy-conversion efficiencies of less than 1 percent. This impasse was finally overcome with the development of the silicon solar cell by Russell Ohl in 1941. In 1954, three other American researchers, G.L. Pearson, Daryl Chapin, and Calvin Fuller, demonstrated a silicon solar cell capable of a 6-percent energy-conversion efficiency when used in direct sunlight. By the late 1980s silicon cells, as well as those made of gallium arsenide, with efficiencies of more than 20 percent had been fabricated. In 1989 a concentrator solar cell, a type of device in which sunlight is concentrated onto the cell surface by means of lenses, achieved an efficiency of 37 percent due to the increased intensity of the collected energy. In general, solar cells of widely varying efficiencies and cost are now available.StructureModern solar cells are based on semiconductor physics -- they are basically just P-N junction photodiodes with a very large light-sensitive area. The photovoltaic effect, which causes the cell toconvert light directly into electrical energy, occurs in the three energy-conversion layers.The first of these three layers necessary for energy conversion in a solar cell is the top junction layer (made of N-type semiconductor ). The next layer in the structure is the core of the device; this is the absorber layer (the P-N junction). The last of the energy-conversion layers is the back junction layer (made of P-type semiconductor).As may be seen in the above diagram, there are two additional layers that must be present in a solar cell. These are the electrical contact layers. There must obviously be two such layers to allow electric current to flow out of and into the cell. The electrical contact layer on the face of the cell where light enters is generally present in some grid pattern and is composed of a good conductor such as a metal. The grid pattern does not cover the entire face of the cell since grid materials, though good electrical conductors, are generally not transparent to light. Hence, the grid pattern must be widely spaced toallow light to enter the solar cell but not to the extent that the electrical contact layer will have difficulty collecting the current produced by the cell. The back electrical contact layer has no such diametrically opposed restrictions. It need simply function as an electrical contact and thus covers the entire back surface of the cell structure. Because the back layer must be a very good electrical conductor, it is always made of metal.How do solar cells workA solar cell is a sandwich of n-type silicon (blue) and p-type silicon (red).1.When sunlight shines on the cell, photons (light particles)bombard the upper surface.2.The photons (yellow blobs) carry their energy down through thecell.3.The photons give up their energy to electrons (green blobs) inthe lower, p-type layer.4.The electrons use this energy to jump across the barrier into theupper, n-type layer and escape out into the circuit.5.Flowing around the circuit, the electrons make the lamp lightup.Solar Power - Advantages and Disadvantages Solar Power AdvantagesThere are many advantages of solar energy. Just consider the advantages of solar energy over that of oil:· Solar energy is a renewable resource. Although we cannot utilize the power of the sun at night or on stormy, cloudy days, etc., we can count on the sun being there the next day, ready to give us more energy and light. As long as we have the sun, we can have solar energy (and on the day that we no longer have the sun, you can believe that we will no longer have ourselves, either).· Oil, on the other hand, is not renewable. Once it is gone, it is gone. Yes, we may find another source to tap, but that source may run out, as well.· Solar cells are totally silent. They can extract energy from the sun without making a peep. Now imagine the noise that the giant machines used to drill for and pump oil make!· Solar energy is non-polluting. Of all advantages of solar energy over that of oil, this is, perhaps, the most important. The burning of oil releases carbon dioxide and other greenhouse gases and carcinogens into the air.·Solar cells require very little maintenance (they have no moving parts that will need to be fixed), and they last a long time.· Although solar panels or solar lights, etc., may be expensive to buy at the onset, you can save money in the long run. After all, you do not have to pay for energy from the sun. On the other hand, all of us are aware of the rising cost of oil.· Solar powered lights and other solar powered products are also very easy to install. You do not even need to worry about wires.Here are the disadvantages of solar energy:•The initial cost is the main disadvantage of installing a solar energy system, largely because of the high cost of thesemi-conducting materials used in building one.•The cost of solar energy is also high compared tonon-renewable utility-supplied electricity. As energy shortages are becoming more common, solar energy is becoming moreprice-competitive.•Solar panels require quite a large area for installation to achievea good level of efficiency.•The efficiency of the system also relies on the location of the sun, although this problem can be overcome with the installation of certain components.•The production of solar energy is influenced by the presence of clouds or pollution in the air.•Similarly, no solar energy will be produced during nighttime although a battery backup system and/or net metering willsolve this problem.Development, deployment and economicsBeginning with the surge in coal use which accompanied the Industrial Revolution, energy consumption has steadily transitioned from wood and biomass to fossil fuels. The early development of solar technologies starting in the 1860s was driven by an expectation that coal would soon become scarce. However development of solar technologies stagnated in the early 20th century in the face of the increasing availability, economy, and utility of coal and petroleum.The 1973 oil embargo and 1979 energy crisis caused a reorganization of energy policies around the world and brought renewed attention to developing solar technologies.Deployment strategies focused on incentive programs such as the Federal Photovoltaic Utilization Program in the US and the Sunshine Program in Japan. Other efforts included the formation of research facilities in the US (SERI, now NREL), Japan (NEDO), and Germany (Fraunhofer Institute for Solar Energy Systems ISE).Between 1970 and 1983 photovoltaic installations grew rapidly, but falling oil prices in the early 1980s moderated the growth of PV from 1984 to 1996.Photovoltaic production growth has averaged 40% per year since 2000 and installed capacity reached 10.6 GW at the end of 2007,and 14.73 GW in 2008.Since 2006 it has beeneconomical for investors to install photovoltaics for free in return for a long term power purchase agreement. 50% of commercial systems were installed in this manner in 2007 and it is expected that 90% will by 2009. Nellis Air Force Base is receiving photoelectric power for about 2.2 ¢/kWh and grid power for 9 ¢/kWh.Commercial concentrating solar thermal power (CSP) plants were first developed in the 1980s. CSP plants such as SEGS project in the United States have a levelized energy cost (LEC) of 12–14 ¢/kWh.The 11 MW PS10 power tower in Spain, completed in late 2005, is Europe's first commercial CSP system, and a total capacity of 300 MW is expected to be installed in the same area by 2013.In August 2009, First Solar announced plans to build a 2 GW photovoltaic system in Ordos City, Inner Mongolia, China in four phases consisting of 30 MW in 2010, 970 MW in 2014, and another 1000 MW by 2019. As of June 9, 2009, there is a new solar thermal power station being built in the Banaskantha district in North Gujarat. Once completed, it will be the world's largest.。

环保资源—太阳能英文翻译Environmental resources - solar energy
环保资源—太阳能随着城市人口的增加，城市面积的不断扩大，红绿灯安装在各个道口上，已经成为疏导交通车辆最常见和最有效的手段。
但这一技术在19世纪就已出现了。
1858年，在英国伦敦主要街头安装了以燃煤气为光源的红，蓝两色的机械扳手式信号灯，用以指挥马车通行。
这是世界上最早的交通信号灯。
1868年，英国机械工程师纳伊特在伦敦威斯敏斯特区的议会大厦前的广场上，安装了世界上最早的煤气红绿灯。
它由红绿两以旋转式方形玻璃提灯组成，红色表示“停止”，绿色表示“注意”。
1869年1月2日，煤气灯爆炸，使警察受伤，遂被取消。
1914年，电气启动的红绿灯出现在美国。
这种红绿灯由红绿黄三色圆形的投光器组成，安装在纽约市5号大街的一座高塔上。
红灯亮表示“停止”，绿灯亮表示“通行”。
1918年，又出现了带控制的红绿灯和红外线红绿灯。
带控制的红绿灯，一种是把压力探测器安在地下，车辆一接近红灯便变为绿灯；另一种是用扩音器来启动红绿灯，司机遇红灯时按一下嗽叭，就使红灯变为绿灯。
红外线红绿灯当行人踏上对压力敏感的路面时，它就能察觉到有人要过马路。
红外光束能把信号灯的红灯延长一段时间，推迟汽车放行，以免发生交通事故。
总之，信号灯的出现，使交通得以有效管制，对于疏导交通流量、提高道路通行能力，减少交通事故有明显效果。
但是，目前随着世界各国石油、煤炭等自然资源的匮乏，全国大部分地区为了对付缺电，实行了分地区分时段的拉闸限电措施，而交通灯作为重要的指挥工具也由于市电的断电而不能工作，造成了交通安全隐患。
随着全球能源危机和环境恶化，太阳能以其无污染、无噪声、拆装移动简易、不会破坏市容环境、不受地理位置限制等特有的优势，将代替传统的不可再生能源，成为人类社会取之不尽、用之不竭的低成本环保清洁能源，太阳能发电将走入普通老百姓的日常生活，节约电费和能源，保护环境，造福人类。
因此，利用太阳能对交通灯进行供电，通过带有蓄电池的太阳能电池板跟普通交通灯相连，来实现利用太阳能给交通灯供电，不仅能够节约资源，而且使其在市电断电情况下也能正常工作。

With the advancements in solar technology, photovoltaic (PV) panels have become more efficient and cost-effective, making them a viable option for both residential and commercial use. Solar panels can be installed on rooftops, deserts, and even floating on water bodies, harnessing the vast amount of solar radiation that reaches the Earth's surface.Electric vehicles, on the other hand, offer a clean and silent mode of transportation. Unlike traditional gasoline-powered vehicles, EVs do not emit harmful greenhouse gases or air pollutants, significantly reducing the environmentalimpact of transportation. With the development of battery technology, EVs now have a longer range and faster charging times, making them more convenient and practical for daily use.The combination of solar energy and EVs creates a virtuous cycle. Solar panels can be installed at charging stations or even integrated into the design of EVs, allowing them to be charged directly from solar power. This not only reduces the carbon footprint of transportation but also reduces the demand for fossil fuels, further promoting the adoption of renewable energy.Moreover, the integration of solar energy and EVs creates new business opportunities and jobs. The manufacturing, installation, and maintenance of solar panels and EVs require skilled workers, driving economic growth and creating sustainable employment. Additionally, the widespread adoption of EVs will lead to the development of a robust charging infrastructure, further stimulating economic activity.In conclusion, the integration of solar energy and electric vehicles holds the key to sustainabletransportation. By harnessing the power of the sun and adopting clean modes of transportation, we can reduce our carbon footprint, protect the environment, and create a better future for ourselves and our planet.**太阳能与电动汽车：可持续交通的未来**面对能源危机和环境保护的紧迫需求，太阳能与电动汽车的结合已成为可持续交通的一种有前途的解决方案。
Solar Energy太阳能英语作文
Solar EnergyName: IsabellaSchool: Inner Mongolia University of Science and Technology Academic adviser: Andrew MilanekDate: 2013/12/08Imagine a world where sunlight can be captured to produce electricity anywhere, on any surface.
