能源节约作文篇1
the world is not only hungry, but also thirsty for water. this may seem strange to you, since nearly 75 % of the earth's surface is covered with water. but about 97% of this huge amount is sea water, or salt water. man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes, underground , and other sources. and we cannot
even use all of that, because some of it is in the form of icebergs and glaciers. even worse, some of it has been polluted.
however, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. but our need for water is increasing rapidly-- almost day by day. only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. a limited water supply would have a bad effect on agriculture and industry. let me give you just one small exampie of how necessary water is to industry. did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?
we all have to learn how to stop wasting our precious water. one of the first steps we should take is to develop ways of reusing it. experiments have already been done in this field, but only on a small scale. for us, the systems are as important as the spacecraft.

世界是不只有饥饿的，但是也口渴的为水。 这可能对你似乎很奇怪，因为将近75%的地球的表面布满水。但是大约97%的这个极大的部分是海洋水、或含盐的甜水。人们只能喝而且使用另一个3%——来自河的淡水，湖，地下水，和其他来源。而且因为它其中的一些是以冰山的形式，所以我们不能够甚至使用那全部和冰河。甚至更坏，它其中的一些已经被污染。
然而，因为事情今天站，这个少量淡水，正在不变地被降雨量代替，仍然对我们充足。 但是我们的对水的需要正在快速地增加--几乎日复一日。只有当如果我们采取措施现在处理这一个问题我们能稍后避免一个严格的全世界的水不足吗。一个被限制的`给水会有对农业和工业的差劲影响。让我只是给你一个小必需水如何对工业的例。你知道生产一吨钢，它拿水的大约91000公升?
我们全部必须学习该如何停止浪费我们的宝贵水。 我们应该拿的首要步骤之一将发展重复使用它的方式。实验在这一个栏位被做，但是只有在一个小规模上。为我们，系统很像太空船一样的重要。

作为一个中学生,我们能做什么来节约能源吗?t保护环境对我们来说是非常重要的今天。不要扔垃圾在任何地方。我们应该种植尽可能多的树。
我们应该学会节约水从一个勇时代。不允许浪费水。我通常使用我洗了衣服的水浇花或干净的地板上。我认为这也是节约用水的好办法,不是吗?我总是骑自行车去上学,但有时我步行去上学。它不仅可以保护环境,也是一种保持健康的好方法。有必要回收尽可能多。有许多事情我们可以做来节约能源,比如关掉灯当我们离开。

能源节约作文篇3
看,奔腾不息的江河,星罗棋布的湖泊,壮阔浩瀚的海洋,皑皑的雪山共同构建起地球广阔的水圈.水是生命的源泉,是人类经济发展的动脉.
亲爱的同学们,当我们看到鲜艳的五星红旗冉冉升起时,当我们唱起雄壮的国歌时,我们的心中必定充满了自豪和幸福.但同时,你们可曾为祖国的水资源而节约吗?曾经我们家园地大物博,而这几年是怎么了?山有吃穷之日,水有饮尽之时,先人开发的水资源,被世人利用的差不多了,我们的子孙还有可能继续在这片土地上生长吗?
如今的中国是个缺乏水资源的国家.据资料显示,地球上97.5%的水是咸涩的海水，它既不能直接饮用，也不能灌溉。既使在佘下的2.5%的淡水中人类真正能够利用的还不到总量的1%。啊水，不淡水，对我们来说是多么宝贵！但尽管这样人们还是屡教不改，肆无忌惮地浪费水源。那我们的生活将会多么不堪呀......到那时，田地一定会荒芜，遍地干旱，使得人们不能安居乐业，有的人们还会渴死......亲爱的同学们难道你们希望这种悲剧再次发生吗？所以我们一定要节约用水，有水当思无水之苦呀！“不要让我们的眼泪成为世界上最后一滴水，”这句话我绝不是危言耸听。
因为如今的我深深地懂得提倡节约不是一阵风，不是一个活动，而是持之以恒的过程。没有结束，只有永远。啊，同学们节约水源是一种责任，一种美德，一种品质。我们每个人手中都掌握着一份民族生息发展的命脉。成之损之，爱之毁之，不都在我们吗？所以就让我挽起手来，大力弘扬中华的传统美德——节约能源，从身边做起。

能源节约作文篇4
“勤俭节约”是中华民族的传统美德。我常听人们说：“浪费可耻，节约光荣。”不错，因为地球上不是每种能源都是取之不尽，用之不竭的。如：水资源等，如果没有了这些资源，后果会很严重，而且会对人类造成很大的威胁。
据我所知，地球上的水资源并不是特别充足。地球储水总量13.7亿立方公里，而淡水却只占其中的2.5%，淡水的68.7%又封存于两极和高山永久性积雪之中，而地球上只有不到1%的可利用淡水。可想而知，地球上仅有不到1%的可利用淡水，那么我们中国的淡水资源又占其中的多少呢？不用说，地球上有这么多的国家，而我们中国的淡水资源可能只占其中的百分之几或千分之******！
同学们，行动起来。地球上的水都这么少，而我们中国的淡水资源简直更是微不足道了，既然我们中国就只有这么一点淡水资源，那岂不是更要节约了吗？只要从小事做起。
比如用淘米的水洗菜，洗菜后还可以用来擦地板，然后用来冲厕所。洗手时最好用一个盆子打水，免得流走浪费了，手洗干净了用剩下的水洗脚，然后用其余的水浇浇花或拖拖地板。还有就是无论在任何地方如果发现水龙头没关紧，都要把水龙头关紧了才走。发现有人浪费水或有意污染水，应该立刻前去阻止或给予劝告。最重要的是——不能浪费“一滴水”，如果全世界每人每天浪费一滴水，那地球该要损失多少水呀！
我此时想对全国人民说：“节约能源，从小事做起！”我深深地知道，如果我们浪费或污染水，水不但会很难过，而且还会伤心地哭泣，我更了解，当它哭哑嗓子的那一天，就是人类即将灭绝的日子---“世界末日”……
能源节约作文篇5
with the fast development of economy and society many problems have been appeared and caused some negative impacts on our lives. energy shortage is one of the most serious problems in the world.
many reasons can account for energy shortage. in the first place the demand for energy has been substantial increased as various industries develop rapidly. moreover the population growth is another factor. as the time elapses the increasing number of population has required more energy for living and working and other areas. last but not least wasting energy is a great serious and common phenomenon all the time.
in order to solve the problem all of us should go into action together. for one thing we should try our best to find out the renewable energy to replace the energy that we consumed most. for another everyone should develop the concept that energy is limited and we have to form a habit to save energy. and we can save energy in our lives by starting from small details such as turn off the light when leaving.
in a word energy shortage has been a big and serious problem in the world. therefore we should make our efforts to solve it by finding new renewable energy and saving energy and any other possible ways.
