高分英语作文1:Wind energy

Common energy types and energy classification [point] the understanding of common energy types includes: coal, oil, natural gas, ethanol, hydrogen, solar energy, nuclear energy, wind energy, electric power, chemical industry, water, tide and geothermal energy. The classification standards are different. Now, the following four categories are mainly described in different subcategories: renewable energy in the In nature, some of them can be recycled, called renewable energy, such as wind energy, solar energy, hydraulic power, biomass energy, geothermal energy, ocean energy and other non fossil energy.

Some non renewable energy in nature is called non renewable energy (once consumed, it can not be regenerated for hundreds or even thousands of years, such as coal, oil, natural gas and other fossil fuels At present, the most widely used energy on our planet can be divided into: clean energy, which does not pollute the environment in the process of energy use, is called clean energy, such as solar energy, wind energy, ocean energy, hydropower and geothermal. Non clean energy, which pollutes the environment in the process of energy utilization, is called non clean energy, such as coal, oil and natural gas With the development of science and technology, human can be a kind of non clean energy. The ultimate goal of human energy utilization is carbon free economy.

According to the degree of processing energy, it can be divided into: primary energy in nature; unprocessed natural energy conversion is directly called primary energy, such as coal, oil, natural gas, solar energy, wind power, hydraulic power, geothermal energy and nuclear energy The products that people need are called secondary energy, such as electricity, gas, steam and various petroleum products.

Many cities in the world are facing increasingly serious air pollution. A method to solve the problem of urban air pollution is suggested. In my opinion, reducing air pollution is facing a tough battle.

This war has led to a series of health hazards. The real way to solve air pollution is to replace fossil fuels with clean energy such as solar energy and wind energy, and to produce clean energy by solar energy and wind energy, and pollution of fossil fuel and other polluting energy can be greatly reduced. The excessive use of fossil fuels such as coal has led to the emission of pollutants such as nitrogen oxide and carbon dioxide.

According to official statistics, this is a major threat to air quality. The emission of carbon dioxide is up to million tons, which poses a serious threat to air quality. Therefore, using Taiyang energy and wind energy can effectively reduce the emission of pollutants from fossil fuels and significantly improve air quality; Secondly, renewable energy such as solar energy and wind energy are pollution-free and environmental protection well known.

Solar energy and wind energy are clean, free and inexhaustible energy, which provide energy for cooking, lighting, heating and refrigeration, and there is no direct emission. Therefore, to win the fight of air pollution, we must take some urgent measures immediately. Replacing fossil fuels with sustainable clean energy is a feasible alternative to fossil fuels.

New clean energy can greatly reduce air pollution in some parts of China, which deserves great attention.

世界上许多城市都面临着日益严重的空气污染。建议一种解决城市空气污染问题的方法。在我看来,减少空气污染正面临着一场艰苦的战斗,这场战争已经导致了一系列的健康危害,解决空气污染的真正办法是首先用太阳能、风能等清洁能源替代化石燃料,利用太阳能和风能生产清洁能源,化石燃料等污染能源的污染可以大大减少。

煤炭等化石燃料的过度使用已经导致氮氧化物和二氧化碳等污染物的排放,根据官方统计,这是对空气质量的一个主要威胁,二氧化碳排放量达百万吨,对空气质量构成严重威胁,因此,利用太阳能和风能可以有效减少化石燃料的污染物排放,显著改善空气质量;其次,太阳能、风能等可再生能源是无污染、环保的众所周知,太阳能和风能是清洁、免费、取之不尽的能源,它们为烹饪、照明、取暖和制冷提供了能源,而且没有任何直接排放。因此,要打赢空气污染的战斗,必须立即采取一些紧急措施,以可持续的清洁能源取代化石燃料是当务之急作为化石燃料的一种可行的替代品,新型清洁能源可以大大减少空气污染中国部分地区的空气污染状况明显严重,值得高度关注。

满分英语范文3:风能

With wind turbines, wind energy is constantly put into our homes. This paper uses the low-speed rated 5kW wind turbine permanent magnet. Due to the small amount of instability of the wind turbine, it starts to turn from the work, converting wind energy into mechanical energy, and then converting mechanical energy into electrical energy.

Its output voltage and current are constantly changing. The controller must be rectified by the regulator, and then be converted into DC power to charge the battery When the chemical energy is converted into AC, the battery can be used as long as the DC voltage is output to the corresponding voltage, which ensures the stable use. In this paper, the SCR trigger circuit is used to complete the selection of rectifier circuit to inverter power supply, and SG integrated inverter is used to realize the conversion process.

利用风力涡轮机,风能是不断地投入到我们家中使用的。本文使用的是低速额定为5KW的风力发电机永磁,由于风力发电机的少量不稳定,它开始从工作中转向,将风能转化为机械能,然后将机械能转化为电能,它输出的电压和电流是不断变化的,控制器必须经过调节器的整流,变成直流电再给电池充电,风力发电机将电能转化为化学能然后有逆变器的功率保护电路,电池在化学能转化为交流电的情况下,只要将直流电压输出到相应的电压即可使用,这就保证了稳定的使用本文是用晶闸管触发电路来完成整流电路到逆变电源的选择开关控制器SG集成逆变器来实现的实现转换过程。
