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.

可再生能源英文：Renewable energy。

可再生能源是指自然界中可以不断利用、循环再生的一种能源，例如太阳能、风能、水能、生物质能、海洋能、潮汐能、地热能等。 随着世界石油能源危机的出现，人们开始认识到可再生能源的重要性。

人类历史进程中长期依赖的能源都是可再生能源，如薪柴、秸秆等属于生物质能源，另外还有水力、风力等，这些能源大部分都来自太阳能的转化，是可以再生的能源资源。

人类近代社会大规模开发利用的煤炭、石油、天然气等化石能源，其能量来源实际上也是源自太阳能的转化，但它们是地球在远古时期的演化化过程中形成和储存下来的，对于我们人类来说一旦用完就无法恢复和再生，因此属于不可再生的能源资源。

实践证明，可再生能源不仅能够提供清洁替代能源，更重要的是可以拉动装备制造等相关产业发展，是后国际金融危机时期加快经济发展方式转变和经济结构调整的有效途径。

开发利用可再生能源，对于保障能源安全、保护生态环境、实现可持续发展具有重要意义。要把发展可再生能源作为一项重大战略举措，切实抓紧抓好。

(1) of the last century the late 50's early 60's the first prototype nuclear power plant construction

(2) 60's to 70's built a large number of unit capacity in the 600 ~ 1400 MW of the standard nuclear power plant, which is currently the world's 439 nuclear power plants are running (June 2002 statistics) of the subject

(3) 80, began development in the market since the late 90's advanced light water reactor (ALWR) nuclear power plant.

Gen-IV concept was first in the June 1999 meeting of the American Nuclear Society's annual meeting. In the winter that year in November at the annual meeting of the Society to further the development of a clear vision of Gen-IV. United States, France, Japan, Britain and other nuclear countries formed in 2000, Gen-IV International Forum, to be used 2 to 3 years to complete development of Gen-IV research and development objectives plan. The overall goal of this project is around 2030, to provide to the market economy can solve nuclear energy, safety, waste disposal and the prevention of nuclear proliferation Gen-IV.

2 Gen-IV research and development goals

The current Gen-IV advanced nuclear energy system concept is still relatively vague, the international community has no exact definition. However, there has been clear that the "advanced nuclear energy systems" rather than "advanced reactors." It should meet the security, economic, sustainable development, minimal waste generation, fuel, and low risk of the proliferation of basic standards.

2.1 The goal of sustainability

Comparison of the authority in accordance with the definition of the essence of sustainability is how to sustain Earth's life support systems to meet basic human needs. For a particular system, it is a default in the stated objectives and can successfully stage the degree of its development, coordination, sustainability, sustainable development and stable binding within the threshold probability, that is, its success extended to sustainable development goals. Gen-IV of the sustainability objectives include the efficient use of fuel, waste management and nuclear proliferation in the physical limit. Namely:

Sustainability objective 1: Gen-IV will be available worldwide to meet clean air requirements, long-term, reliable, fuel efficient use of sustainable energy.

Sustainability objective 2: Gen-IV nuclear waste generated was minimalused in nuclear waste management will be both properly safe disposal of nuclear waste, but also significantly reduce the dose of the staff to improve public health and protection of the environment.

Sustainability objective 3: Gen-IV nuclear fuel cycle should lead to commercial possibilities of nuclear proliferation limited to a minimum, making it difficult to be converted to military use, and to prevent terrorist activities in the physical provision of more effective measures.

2.2 The objectives of security and reliability

R &D in nuclear energy systems and operation, safety and reliability is a priority fundamentals. In normal operation, or hypothetical transient conditions, nuclear energy systems must maintain its safety margin, to prevent accidents and incidents are effective mitigation measures. At the same time, requiring a high reliability.

Over the years, improved security and reliability of nuclear energy systems, reducing the frequency of radioactive release outside the plant and thereby reduce the probability of a serious accident, has been a clear trend. Gen-IV through further improvements to achieve higher security and reliability, to better protect employees, public health and the environment. In this regard, Gen-IV also has three objectives:

Safety and reliability objectives 1: Gen-IV in a safe and reliable operation will be significantly better than other aspects of nuclear energy systems.

The goal is to induce an accident or by reducing the general accident incident evolved into a serious accident, equipment problems and human factors to increase the number of questions the safety of operation. This goal is also to improve the reliability of nuclear power by strengthening the economy of the system. To achieve these operational goals, to support strengthening of public confidence in the safety demonstration, you need to make appropriate design requirements and be careful.

In order to improve the security and reliability to the highest level, fourth-generation nuclear energy systems must continue to use the industry and regulators to enhance public confidence and to establish relevant laws and regulations, and using future advanced technologies.

Safety and reliability goals 2: Gen-IV core damage highly unlikelyeven damage, the degree is also very light.

The goal of the owner / operation is vitally important. Over the years, people have been committed to reducing the probability of core damage. The measures include the use of PRA methods to develop user requirements documents, in the introduction of passive safety systems concepts.

Safety and reliability of objective 3: in the accident outside the plant under the conditions of no release, no plants outside the emergency.

The public, especially those living in the vicinity of nuclear facilities, the residents of the need to secure nuclear power plant outside the emergency is not a reliable proof. Therefore, Gen-IV design direction is an effort on the design and use of advanced technology through the abolition of emergency outside the factory. This is a revolutionary improvement of nuclear safety, it shows: no matter what nuclear power plant accident, will not result in damage to the public outside the plant.

2.3 Economic objectives

Gen-IV would take significant steps to reduce the cost of new nuclear power plant investment and financial risk, or its sustainability, safety and reliability of the advantages would be higher capital costs and generation costs and the corresponding high-risk flood. For a long time, nuclear power plants mainly with basic load. This situation is changing, the global energy market is controlled by the transition to deregulation, there will be more independent power generation companies and business owners (who runs) into the deregulated electricity market. This means that the nuclear power plant being developed to consider the potential for more plant owners, the future of nuclear energy system to adapt to different requirements, including load following and power smaller units. Most of 已建和在建 economic competitiveness of nuclear power stations is not ideal. As China's energy sector development and deepening of power system, improve the economy of the requirements of nuclear power will be more urgent. Currently, the unit cost of new nuclear power plants ($ 1500 ~ 2000/kW, is the unit cost of fossil fuel power plants 2 to 4 times) and longer construction time, processing time, retired time, with other power production methods should not be compared The. To be able to compete with other electricity production, nuclear power plant construction should be met:

* Initial investment (overnight rate) is less than $ 1,000 per kilowatt

* The total cost of electricity production should be less than 3 cents / kWh

* Construction period is less than 3 years.

Economic goals 1: Gen-IV period in the whole economy of life is better than other energy systems.

To ensure that nuclear energy system has become the world's energy supply system in an indispensable part of the needs of the whole life cost advantage of the period. Lifecycle costs include four major components: construction investment, operation and maintenance costs, fuel cycle costs, decommissioning and decontamination costs. There are other important factors affecting the whole life cycle costs, such as financing conditions, the duration of the project, construction progress, the capacity factor and power plant life. Currently, the investment cost is high and the construction of new nuclear power plants is too long the major obstacles in the financial, operating and maintenance costs while the existing power plant has been greatly improved in recent years. Of Gen-IV, the whole life cycle costs of all the factors to be better than other energy sources (including the existing core systems) to ensure their competitiveness.

Economic objective 2: Gen-IV level of the financial risk of financial and other energy projects the level of risk.

In a competitive capital market, to raise the funds needed for the building, Gen-IV on the financial risk must be reduced to or remain in the competition for new levels of project financing.

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? ...
