可再生能源 优缺点 英文

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。

关于能源短缺的英语作文：

With the rapid development of economy and society, there are many problems, which bring some negative effects to our life. Energy shortage is one of the most serious problems in the world. Many reasons can explain the energy shortage.

With the rapid development of various industries, the demand for energy has also increased greatly. With the passage of time, population growth is another factor. The demand for life, work and other aspects of population growth is also increasing.

Energy waste has always been a serious and common problem In order to solve this problem, all of us should act together for one thing. We should try our best to find new energy to replace our most consumed energy. Everyone should establish the concept that energy is limited.

We should form the habit of saving energy. We can start from small things, such as turning off the lights in a word, and energy shortage It is a major and serious problem in the world. We should solve this problem by finding new renewable energy, saving energy and any other possible ways.

译文

随着经济和社会的快速发展，出现了许多问题，给我们的生活带来了一些负面影响。能源短缺是世界上最严重的问题之一。许多原因可以解释能源短缺。

随着各行业的快速发展，对能源的需求也大大增加。随着时间的推移，人口增长是另一个因素。人口增长对生活、工作和其他方面的需求也在增加。

能源浪费一直是一个严重而普遍的问题。为了解决这个问题，我们大家应该为一件事共同行动。我们应该尽最大努力寻找新能源来取代我们消耗最多的能源。每个人都应该树立能源有限的观念。

我们应该养成节约能源的习惯。我们可以从小事做起，比如一句话就关灯，能源短缺是世界上一个重大而严重的问题。我们应该通过寻找新的可再生能源、节约能源和任何其他可能的方式来解决这个问题。
