ways of save energy英语作文:

Energy shortage is a very serious problem in the world. Many people worry that energy resources on the earth will be exhausted if we use them in an unchecked way. This, most people agree, will cause serious problems and even crisis and jeopardize the survival of mankind .

On the one hand, most people agree that the problem can be solved in one way or another. One is to conserve and save our energy. Energy refers not only to coal, oil, or natural gases but also to goods, land and water, etc. Most countries have realized the wastefulness in their using of energy. They are trying to conserve energy.

For example, some countries have a daylight saving system to use less electricity for lighting. Some cities have enforced water savers at public such as restrooms and bars. Some have enforced serious penalties on overuse of electricity, water, and farming land. By these means, people hope the drain on energy resources could be slowed down.

However, conservation alone cannot solve the problem. Another way, perhaps the best I think, is to develop new energy resources. Obviously, no matter how hard we try to save energy resources and how abundant they are, we will use them up sooner or later. I think there are many energy resources that we can develop and utilize.

We don’t have to depend only on the current conventional energy resources. There are many other energy resources that we can develop such as nuclear power, waterpower and solar power. These resources, if developed, can completely replace the conventional energy and thus solve the problem of energy shortage.

能源短缺是世界上一个非常严重的问题。许多人担心地球上的能源资源将被耗尽,如果我们在一个未经检查的方式使用它们。这一点,大多数人同意,将导致严重的问题,甚至危机和危及人类的生存。

一方面,大多数人同意,可以以一种方式或另一种方式来解决问题。一个是保护和拯救我们的能源。能源不仅是指煤炭、石油、或自然气体,也是商品,土地和水等大多数国家已经意识到使用能源的浪费。他们试图节省能源。

例如,一些国家有一个日光节约制度使用更少的电力照明。一些城市实施水储户在公共休息室和酒吧等。有些执行严重惩罚过度使用的电力,水,和农业土地。通过这些手段,人们希望在能源资源的消耗可能会放缓。

然而,保护本身并不能解决问题。也许最好的我认为,另一种方法是开发新的能源资源。很明显,无论我们如何努力节约能源资源和他们有多么丰富,迟早我们将使用它们。我认为有许多能源资源,我们可以开发和利用。

我们不需要只取决于当前常规能源资源。还有许多其他的能源资源,我们可以开发,如核能,水力和太阳能。这些资源,如果发达,完全可以替代传统的能源,从而解决能源短缺的问题。

environmentally friendly renewable energy

环保可再生能源

President Jimmy Carter, in an address to the nation, proposed that by the end of the century, 20% of the electricity used in the U.S. should be derived from the sun. At the time he made the statement, it seemed like an environmentally friendly vision that could be accomplishedhowever, as we enter the year 2002, solar and wind generated power only supply about 2% of the nation’s demand for electricity. In the past, the barrier that separated wind and solar energy from fossil fuel energy was cost efficiency. Recently, many advances in technology may have broken that cost barrier, and it may no longer be an obstacle for industry and consumers to have cheaper access to renewable energy. Some officials comment that the prices of renewable energy are about 1/8 of what they were 12 years ago, and they expect solar and wind powered energy to be the fastest growing energy source for individual buildings and houses over the next few decades. In fact, in some areas, wind farms are growing in demand because they are cheaper to add than non-renewable fossil fuel energy sources. Some energy analysts are optimistic that by the year 2020, wind and solar energy may supply 10% of the nation’s energy demands. Other renewable energy sources such as hydroelectric dams, which currently generate about 8–10% of the nations electricity, are not expected to grow in demand. Although hydroelectricity is viewed as a clean energy source, it does come at a high price of altering the natural flow of river water, nearby plant and wildlife habitats, and forcing some fish species near extinction. The worksheet includes the URL for the U.S. Department of Energy web site.

Preserving Natural Resources

Through the changes in the ways of making a living in a family over several generations, man has been warned against waste of natural resources and emphasizing the urgent need to preserve these resources.

Ever since man appeared on the earth, man's survival has been heavily relied on nature. Almost everything we use in our everyday life comes from notate, ranging from the food we eat, the water we drink, to the wood which is tm'ned into furniture.With the development of technology and population growth, the amount and range of materials used has increased at an alarming rate.However, natural resources are not inexhaustible. Some reserves are already on the brink of exhaustion and there is no hope of replacing them. The widespread water shortage is an example in point. If man continued to squander natural resources with no thought for the future, the later generations would be in danger. It is up to us to take effective measures before the situation gets out of hand.

保护自然资源

经过几代人谋生方式的变化,人类已经得到警告,要反对浪费自然资源,急需保护这些资源。

自从人类在地球上出现以来,人类的生存就一直依赖自然。我们日常生活所用的一切,从吃的东西、喝的水到做家具的木材,几乎都来自自然。随着科学技术的发展以及人口的增长,所用物品的数量和范围以令人担忧的速度在增长。然而,自然资源并不是无穷无尽的。一些储量已经到了穷尽的边缘,而且没有希望替换它们。分布广泛的水的缺乏就是一个例子。如果人类不为将来着想继续浪费自然资源,后代就会受到威胁。我们应该采取有效措施,防止形势恶化。

08四川 What can I do for our environment? Everyone can do something for our environment. For me, I should try to save electricity in my daily life. For example, if I am the last person leave the classroom in the evening, I will always remember to turn off the lights. In order to protect our forests, I will use paper wisely. I should try to use both sides of paper whenever it is possible. I will not use things like paper cups and disposable chopsticks because they are made of wood. I believe that doing all these *** all things will improve our environment and help make our world a better place to live in. 08陕西Notice Our monitor suggests that we have “Friday News Hour”. But some clas *** ates do not agree. We will have a class meeting in English tomorrow afternoon to discuss this suggestion. Please prepare your talk and take an active part. May 6th, 2008 Dear fellow students, Our monitor suggests that we have “Friday New Hour”. I think that it is a good idea. Everyone knows that we are busy all day. Seldom do we know what is happening both at home and abroad, let alone what we can do for our country. By reading newspapers we can get more information about the world outside. So I think “Friday New Hour” can broaden our mind and enrich our school life. What's more, it will help us improve our reading skills. As for my suggestion, I think it's better to have it ice a week. And we should make a choice about what we'll read. I am sure everyone will benefit a lot from this activity. 08福建Dear sir, I'm Li Hua from Fujian. When I was reading the advertisement , the aim of this activity impressed me greatly, I think it instructive to learn to live together by living together. It is a good opportunity for the only child like me to learn to share and work together. Therefore I remend myself to you without hesitation. As a boy of 17, I am outgoing, good at English and have experience of working well with children aged from 7 to 12, I think it is a kind or win-win activity. For one thing, I can help take care the children. For another thing, I can improve my English, make more friends, and enrich my life during the summer vacation. I am looking forward to your early reply. Sincerely yours, Li Hua 08安徽Dear David, I'm glad that you've noticed our efforts directed towards environmental protection. Thank you for your concern. As too much use of plastic bags has caused serious white pollution, our govenment encourages us to use environment-friendly shopping bags. These bags are made of a variety of material that can be easily treated when they bee rubbish. Besides, they can be reused. More and more people in China have realized the advantages of such bags and started using them. I believe that the wide use of these shopping bags can greatly improve our environment. This is one of the many steps we are to make our country an even cleaner place. Yours, Li Hua 08湖南Sample 1: Thomas Edison Born in American, Thomas Edison was a great scientist and inventor. He once thought to be a boy who was not worth educating. In fact, he was a man full of imagination. I admire Edison a lot because of his great contribution to the world. He had more than 1000 inventions. In his little time, he was always eager to know how things worked, which helped him to earn the nickname “the Wizard of Meio Park”. He was also so diligent that he worked day and night. And this explained why he had so many inventions. What impresses me most is his famous saying, “genius is one percent inspiration and niy-nine percent perspiration”. Probably I cannot be an Edison myself, but I can be a hardworking learner. From him, I realize the secret to success is not when and where you were born, but what you are doing and how you do it in your life. Sample 2: Helen Keller Every time I read “…if I had the power of sight for three days, I cannot help being moved by its author Helen Keller, an ordinary but great American woman. I admire Helen because she is optimistic about life. She became deaf and blind when she was 19 months old. Since then she lived in a world of darkness and silence, and munication seemed only a dream for her. But she never gave up and struggled to lead an active life. Under the guidance of her teacher, Ms. Sulliven, Helen learned to read and write, and became a famous writer. For a disabled person like her, this was really a wonder. Helen has set an excellent example to all of us. Her story tells us that we should value what we have and try our best to overe any difficulty in life. Sample 3: William Shakespeare Do you know Hamlet? Have you read the Merchant of Venice? ...

“活化石”是在种系发生中的某一线系长期未发生前进进化,也未发生分支进化。更未发生线系中断(绝灭),而是处于停滞进化状态的结果。并须仍是现生的种类。

在生境不变,成种率极低的情况下,这些生物在几百万年时间内没有发生什么变化。于是相应的就形成了一些延续了上千万年的古老的生物,同时代的其他生物早已绝灭,只有它们独自保留下来,生活在一个极狭小的区域,被称为“活化石”。

1938年在非洲东南部海中,首次发现残存的总鳍鱼类矛尾鱼,是世界闻名的1种活化石。我国现在的裸子植物银杏、水松和哺乳动物大熊猫等,均被世界公认为珍贵的活化石。

另一些在地史时期,曾广泛分布而长期生存至今的动物,如腕足类的海豆牙等,也是“活化石”,但它们不是孑遗生物。

总之,孑遗生物一定是“活化石”,但“活化石”不一定都是孑遗生物。

化石是埋藏在地层里的古代生物的遗物。最常见的化石是由牙齿和骨骼形成的。古代动物死后,尸体的内脏、肌肉等柔软的组织很快便会腐烂,牙齿和骨骼因为有机质较少,无机质较多,却能保存较长的时间。如果尸体恰好被泥沙掩埋,与空气隔绝,腐烂的过程便会放慢。泥沙空隙中有缓慢流动的地下水。水流一方面溶解岩石和泥沙内的矿物质,另一方面将水中过剩的矿物质沉淀下来或成为晶体,随着水流会逐渐渗进埋在泥沙中的骨内,填补牙齿和骨骼有机质腐烂后留下的空间。如果条件合适,由外界渗进骨内的矿物质在牙齿和骨骼腐烂解体之前能有效地替代骨骼原有的有机质,牙齿和骨骼便完好地保存成为化石。由于化石中的大量矿物质是极为细致地慢慢替代其中的有机质,所以能完整地保存牙齿和骨骼原来的形态,连电子显微镜才能看清的组织形态都能原样保存。天长日久,骨骼的重量不断增加,由原来的牙齿和骨头变成了还保存牙齿和骨头原有的外形和内部结构的石头,这个过程被称作“石化过程”。

除了牙齿和骨骼外,有的动物的粪便也能成化石。例如,有的肉食动物吃肉时是连着碎骨一起吞下的,粪便里有许多没有被消化掉的碎骨,碎骨不容易腐烂,所以也能成为化石。脚印也能成为化石。人或动物踩在泥沙上,造成脚印。泥沙干后,脚印又被另外的物质填满。两种物质都被后来渗进去的矿物质石化后保存下来,但是两种物质的性质不同,软硬不同,容易风化或破坏的程度也不同。一种物质被风化或破坏后,另一种物质便表现为脚印化石。

化石形成的条件

形成条件:

虽然一个生物是否能形成化石取决于许多因素,但是有三个因素是基本的:

(1)有机物必须拥有坚硬部分,如壳、骨、牙或木质组织。然而,在非常有利的条件下,即使是非常脆弱的生物,如昆虫或水母也能够变成化石。

(2)生物在死后必须立即避免被毁灭。如果一个生物的身体部分地被压碎、腐烂或严重风化,这就可能改变或取消该种生物变成化石的可能性。

(3)生物必须被某种能阻碍分解的物质迅速地埋藏起来。而这种掩埋物质的类型通常取决于生物生存的环境。海生动物的遗体通常都能变成化石,这是因为海生动物死亡后沉在海底,被软泥覆盖。软泥在后来的地质时代中则变成页岩或石灰岩。较细粒的沉积物不易损坏生物的遗体。在德国的侏罗纪的某些细粒沉积岩中,很好地保存了诸如鸟、昆虫、水母这样一些脆弱的生物的化石。

新能源汽车的优点:

1、节约燃油能源。一般是用天然气、石油气、氢气、电力作为动力。2、减少废气排放,有效的保护环境。电动汽车不产生尾气,没有污染。氢能源汽车尾气是水,对环境没有污染。因为基本属于零排放,所以也在限号范围外。3、效率高。一般新能源汽车采用新技术,新结构,使它的效率更高。4、噪声低。新能源汽车缺点:1、因为新能源汽车处于起步阶段,技术还不是很成熟。所以充电比较慢,需要数小时。2、车辆保有量低,充电、加气、维修等不太方便。而且新能源汽车充电难,因为普及面小。3、续航里程短。一般车辆排量较小,动力不足,不适合长距离行驶。4、价格不低。现在价格在5-10万的新能源汽车,只有纯电动汽车有批量生产,选择性不是太大。

扩展资料:新能源汽车是指采用非常规的车用燃料作为动力来源(或使用常规的车用燃料、采用新型车载动力装置),综合车辆的动力控制和驱动方面的先进技术,形成的技术原理先进、具有新技术、新结构的汽车。新能源汽车包括纯电动汽车、增程式电动汽车、混合动力汽车、燃料电池电动汽车、氢发动机汽车、其他新能源汽车等。

新能源汽车两大阶段:第一阶段是以混合动力汽车为主,燃料电池车等新能源汽车为辅的发展方向,开拓新能源汽车市场。第二阶段是在纯电动汽车技术成熟的'基础上,纯电动汽车逐步替代混合动力及燃料电池汽车以至于完全占据新能源汽车市场,实现零排放的阶段。中国新能源汽车产业始于21世纪初。2001年,新能源汽车研究项目被列入国家“十五”期间的“863”重大科技课题,并规划了以汽油车为起点,向氢动力车目标挺进的战略。“十一五”以来,我国提出“节能和新能源汽车”战略,政府高度关注新能源汽车的研发和产业化。

新能源汽车的优点一:环保

纯电动汽车在运行过程中可以做到零污染,完全不排放污染大气的有害气体。即使按所耗电量换算为发电厂的排放,造成的污染也少于传统汽车,因为发电厂的能量转换率更高,而且集中排放可以更方便地假装减排治污设备。

新能源汽车的优点 二:省钱

2014年,国家和地方政府给予电动汽车最高11.4万元的补贴,这一举措使电池成本居高不下的电动汽车的售价能够下降到与传统汽车相当的水平。而在油价高企的今天,电动汽车的运行费用是要远小于传统汽车的。

新能源汽车的优点 三:噪音小

电动机在运行中的噪音和振动水平都要远远小于传统内燃机。在怠速和低速情况下,电动汽车的舒适性要远高于传统汽车,随着速度的提升,胎噪和风噪成为噪音的主要来源,两者才回到同一水平上。电动汽车的这一特点对于提升汽车的NVH性能无疑会有很大的帮助。

新能源汽车的优点 四:节能

电动汽车的百公里耗电量为15-20kwh,算上发电厂和电动机的损耗之后,百公里的能耗约为7公斤标准煤。传统汽车按百公里耗油量10L计,能耗约为10公斤标准煤。并且在城市的拥堵环境里,电动汽车的节能优势会进一步放大。

新能源汽车的缺点 一:充电难

在国内充电设施建设滞后的情况下,充电是电动汽车所面临的的一大难题。公共场所充电桩的缺乏严重影响了电动汽车的出行。

新能源汽车的缺点 二:续航里程短

受限于电池的容量,目前大多数的纯电动汽车续航里程都在100-200公里。虽然一再有专家说90%的人每日行驶距离不超过50公里,但是中国消费者对续航的要求比美国人更高,因为很少有中国家庭拥有超过1辆汽车,而美国人可以做到一辆纯电动汽车通勤,一辆传统汽车旅行。纯电动汽车可以满足老百姓平时上下班,但是周末外出,节假日出游的需求,又该如何解决呢?

新能源汽车的缺点 三:充电慢

目前大多数充电桩都是慢充桩,一辆车充满需要5-8小时。虽然可以利用夜间休息时间充电,但是如果遇到什么突发情况,纯电动汽车的充电慢的缺点就会凸显无疑。

新能源汽车的缺点 四:售后服务有待加强

电动汽车结构虽然简单,但是由于动力部分和传统汽车相去甚远,在维修起来还是会遇到一些麻烦。第一个问题就是维修技师的缺乏,现在绝大部分的技师能够修传统汽车,但是缺少电器方面的知识,贸然维修电动汽车不但可能造成车辆的损坏,还有一定的危险性。第二个问题是零部件的稀缺,电动汽车生产量和保有量都少,因此零部件少,价格还高。

以上就是由电动邦我给您分析得关于新能源电动汽车的四大优缺点 。 不知道是否对你们有所帮助,不过时代在更新,相信新能源电动汽车以后的发展肯定会越来越好,并且完善功能。

When talking about renewable energy, we refer to an abundant range of technologies that can provide energy services in the form of electricity, heating and cooling as well as transport solutions. The questions to be addressed to the renewable energy sector should not concentrate solely on whether it is desirable to have a centralised or decentralised energy system or on which source of renewable energy will dominate in the world of tomorrow. The two concepts and all types of energy harnessing the forces of nature must be considered as

interdependent if energy supply, climate mitigation and competitiveness are to be secured and increased in a sustainable manner.

Changes in renewable energy markets, investments, industries, and policies have been so rapid in recent years that perceptions of the status of renewable energy can lag years behind the reality. By 2010, renewable energy had reached a clear tipping point in the context of

global energy supply. Renewables comprised fully onequarter of global power capacity from all sources and delivered 18 percent of global electricity supply in 2009. In a number of countries, renewables represent a rapidly growing share of total energy supply—including heat and transport.
