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。

With the arrival of twenty-first Century, like natural resources and oil, coal and other non renewable and can provide energy for less. Scientists are developing new energy can be long-term use.

This excellent new solar energy inexhaustible, be inexhaustible, be regarded as energy. I was born in this is known as the "World Solar City" of Shandong City, Dezhou. Here is the widely application of solar energy and reasonable. Now the development of Dezhou solar energy industry has been more mature, more than 120 enterprises have solar. In September this year, Dezhou will host the Fourth International Solar Cities congress.

Solar energy, low carbon economy and environmental protection, new energy ideal. Solar energy can power generation, heating (water), and the solar water heater, solar street light, solar cars, solar products. When more and clean energy and low-carbon economy is attracting the attention, discovered in Dezhou can earn money, the original sun.

Solar energy is widely used, because it is as long as the sun can power generation, heating, sun life there five billion years. The small one is 20 square meters of solar roof is equivalent to a 3 Watt generator, 1 years can be generating 3300 degrees.

Solar energy has now begun to spread, low carbon, environmental protection, let us enjoy the sun bring us happiness.

随着21世纪的到来，像石油、煤碳等不可再生而又能提供能量的自然资源越来越少。各国科学家正在开发可长期利用的新能源。

太阳能这个优秀的新能源，被视为取之不尽、用之不竭的能源。而我就出生在这个被称为“世界太阳之城”的城市，山东德州。在这儿太阳能被应用的十分广泛和合理。如今德州太阳能产业的发展已比较成熟，拥有太阳能相关企业120余家。今年9月德州将承办第四届世界太阳城大会。

太阳能之所以被广泛应用，是因为它只要有太阳就能发电、发热，太阳的寿命还有五十亿年呢。一个20平方米太阳能屋顶相当于一台3干瓦的小型发电机组，1年能发电3300度呢。

太阳能现在已经开始普及，为低碳、为环保，让我们一起享受太阳带给我们的快乐吧。

题目：Geothermal resources 正文：Geothermal resources in the world's oldest energy sources. It is estimated that the total thermal energy of the Earth's interior, about all the coal reserves of about 1.7 billion times. Year from Earth's interior heat loss through the surface, equivalent to 1,000 million barrels of oil burning heat. On geothermal sources, there are several hypotheses. Is generally believed that the geothermal evolution of radioactive elements mainly come from the earth's interior heat release, followed by rotation of the Earth's rotation can be generated and gravitational differentiation, chemical reactions, heat release and other rock and mineral crystal. During the formation of the Earth, the total amount of these heat dissipation of heat over the Earth, an enormous heat reserves, so that partial melting of crustal igneous and metamorphic effect. Basic calculation is now out, the planet's core temperature reaches 6000 ° C, temperature of the bottom crust 900-1000 ° C, the surface layer at room temperature (about 15 meters from the ground) about 15 kilometers of the following, the increase of temperature increased with depth. The average temperature of geothermal is about 3 ° C/100 m rate. Geothermal warming rates in different regions are different, close to the average warming rate is called the normal temperature range, higher than the average warming rate of the region, said geothermal anomalies. Geothermal anomaly area is research and development of geothermal resources of the main target. Crustal plate edge, deep fault and the volcanic belt at the other, is obvious geothermal anomalies. Exploration of geothermal resources survey, the general use of surface geothermal survey, drilling and various geophysical methods. Infrared remote sensing technology in exploration in recent years achieved remarkable results. The late 20th century, the exploitation of geothermal resources were mainly shallow, heat storage, and have a fluid (water or artificial irrigation) lead to heat transfer to the surface of the wet geothermal field. Hot dry rock geothermal resources and low-temperature geothermal fields of wetland research development and utilization in the pilot phase. China, rich in geothermal resources, has a long mining history, past the main advantage of hot spring bath treatment. After 1970, in Guangdong Fengshun, Huailai, Tianjin, and Tibet to have been carried out in thermal power generation, building heating, Agricultural greenhouse heating, warm water breeding, irrigation and other aspects Shi Yan Xing Kaifagongzuo, made some achievements.译文：世界上最古老的能源之一。据测算，地球内部的总热能量，约为全约煤炭储量的1.7亿倍。每年从地球内部经地表散失的热量，相当于1000亿桶石油燃烧产生的热量。

关于地热的来源，有多种假说。一般认为，地热主要来源于地球内部放射性元素蜕变放热能，其次是地球自转产生的旋转能以及重力分异、化学反应，岩矿结晶释放的热能等。在地球形成过程中，这些热能的总量超过地球散逸的热能，形成巨大的热储量，使地壳局部熔化形成岩浆作用、变质作用。

现已基本测算出，地核的温度达6000°C，地壳底层的温度达900－1000°C，地表常温层（距地面约15米）以下约15公里范围内，地温随深度增加而增高。地热平均增温率约为3°C/100米。不同地区地热增温率有差异，接近平均增温率的称正常温区，高于平均增温率的地区称地热异常区。地热异常区是研究、开发地热资源的主要对象。地壳板块边沿，深大断裂及火山分布带等，是明显的地热异常区。

普查勘探地热资源，一般采用地表地热调查、钻探和各种物探方法。近年来红外线遥感技术在勘查中取得显著效果。

20世纪末，地热资源的开采对象，主要是埋藏浅、热储量大、有流体（地下水或人工灌水）把热能传引到地表的湿地热田。干热岩地热资源和低温湿地热田的开发利用处在研究试验阶段。

中国的地热资源丰富，有悠久开采历史，以往主要利用温泉洗浴治病。1970年后，在广东丰顺、河北怀来、天津和西藏等地曾进行地热发电、建筑物采暖、农业温室采暖、温水育种、灌溉等多方面试验性开发工作，取得一定成果。

Motor vehicles are not the only air polluters. Coal and oil, used to heat homes and factories and to generate electricity, contain small amounts of sulfur. When the fuels are burned, sulfur dioxide, a poisonous gas, is produced. It is irritating to the lungs. Some cities have passed laws that allow coal and oil to be burned only if their sulfur content is low.

汽车不是唯一的空气污染。煤炭和石油，用于家庭取暖和工厂，并产生电力，含有少量的硫。当燃料燃烧，二氧化硫，一种有毒气体，就产生了。它是刺激到肺部。一些城市已通过法律，允许煤炭和石油只有在其被烧毁硫含量低。

Most electricity is generated by steam turbines. About half of the sulfur dioxide in the air comes from burning fuel to make steam. Nuclear power plants do not burn fuel, so there is no air pollution of the ordinary kind. But the radioactive materials in these plants could present a danger in an accident. Also, there is a problem in disposing of the radioactive wastes in a way that will not endanger the environment.

大部分电力是由蒸汽涡轮机。关于空气中的二氧化硫，使蒸汽一半来自燃料燃烧。核电厂不烧燃料，所以不存在的那种普通的空气污染。但是，在这些植物的放射性物质可能会提出一个意外的危险。此外，还有一个在放射性废物处置的方式，不会危害环境的问题。

Another type of pollution, called thermal (heat) pollution, is caused by both the fuel-burning and nuclear plants. Both need huge amounts of cold water, which is warmed as it cools the steam. When it is returned to the river, the warm water may stimulate the growth of weeds. It may also kill fish and their eggs, or interfere with their growth.

另一种污染类型，称为热（热）污染，是造成双方的燃料燃烧和核电厂。双方都需要的冷水，这是温暖，因为它大量的蒸汽冷却。当返回到河边，温暖的水会刺激杂草生长。它也可以杀死鱼，它们的卵，或干扰他们的成长。

Physicists are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluting material. Also, engineers try to design and locate new power plants to do minimum damage to the environment.

物理学家们正在研究发电对环境损害较小的新方法。与此同时，许多发电厂也在实现现代化以减少污染物质。此外，工程师们尝试设计并找到对环境的损害最小的新的发电厂。
