as a middle school student,what can we do to save energy?t is very important for us to protect the envirnment today.do not throw the rubbish anywhere.we should plant the trees as many as possible.

we should learn to save the water from a very yong age.it is not allowed to waste the water.i usually use the water that i have washed the clothes to water the flowers or clean the floor.i think it is also a good way to save water ,is not it？i always go to school by bike,but sometimes i go to school on foot.it is not only can do to protect the envirnment ,but also a good way tokeep healthy.it is necessary to recycle martianas much as possible.there are many things we can do to save energy,such as turning off the light when we leave.

let's do it from ourselves!

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。

让我们从自己做!

it’s a great honor for me to bring you a brief introduction about the electric power and energy in china.

maybe 15 years ago when i just graduated from my primary school, i had to study in a candle at night and my friend had to suffer from the hot weather in the city in summer, because we are facing a very serious problem as you are facing now, the shortage of the electricity as a result of the repaid development of the society.

but by now this problem has been solved. china has been the largest energy producing and consuming country. in 2015, we have consumed about 4 billion ton standard coal of all kind of energy, and about 5,550 billion kwh of electricity. we have successfully solved this problem because by years construction of power plants, we have 1.4 billion kw of installed capacity now. by 2020, 2030, and 2050, the tota

l install capacity will be about 2 billion, 2.4 billion and 3.6 billion kw, respectively. but this has brought us another serious problem, the serious atmosphere pollution.

just as i mentioned, china consumes about 4 billion ton standard coal of all kinds of energy, the thing is that 70% of this number is real coal. in the energy structure, coal has been taking a leading position in a very long time. thus, the percentage of high-quality energy, such as oil and gas, and clean energy is very low, and the level of electrification is not high. we are trying to modify the structure of the energy consumption. take beijing, who has been suffering the most serious atmosphere pollution, as an example, is closing all of its 4 large coal-fired power plants by 2016, and these will be replaced by gas-fired power plant.

in order to realistic the sustainable development of energy, as well as deal with the air pollution problem, chinese government has published many policies to encourage the development of renewable energy, namely hydropower, wind power, solar power, etc. in 2020 renewable energy will account for 20% of china’s electricity consumption, and 15% of all kinds of energy; in 2030, this proportion will increase to 30% and 20%; and by 2050, this percentage will be 50% and 30%.

so what do we have to achieve that goalwe have about 540,000 mw of technical capacity of hydropower, and by 2015, we have developed about 300,000

mw; we have more than 2 billion kw of onshore wind power potential capacity, and by 2015, we have developed 100,000mw; we have more than 3 billion kw of solar power potential capacity if we are going to use 5% of the desert and we have by now developed 5,000mw. we have the largest hydropower install capacity, the largest wind power install capacity as well as the solar power capacity in the world for years. we are moving forward to our goal step by step. as a request of the scientific develop of renewable energy, china has 13 large hydropower generation bases, which add up to 320,000 mw, planned by hydrochina; china has more than 8 wind power bases, each capacity of which can be more than 1000mw.

having solved the sustainable development and air pollution problem, we have to face other problems. the coal, hydro, wind and solar resources distribute mostly in the north, southwest, and west of china, but the load center is in east and south part of china. so we must face the problem of long-distance transmission of electricity, just as you are facing now. and as a result of the seasons and weather changes, hydropower and wind power must cooperate with the coal-fired power. we have built and operated lots of power grid, and have made many trials to stabilize the grid, and have eventually successfully solved these problems.

what i’m going to say is that, we have been through the problems you are facing now, and we have gain experience from both good and bad sides. we have the ability and confidence to help you solve your problem, to give you the successful experience but not the same fault we have made. that’s why we are here today, please have confidence in us just as we do, and embrace a bright future!

another round of energy crisis is knocking at the door. in 2004, world oil consumption reached a new record, causing oil price in the international market to skyrocket amazingly.

as for china, it was reported that many traditional mineral cities in northeastern china had run into predicament, with their economy collapsed and workers unemployed, only because coal had been mined out.

fossil energy resources, including coal, oil and gas, are unlike sunlight, water power and wind power which are generated consistently. they're not practically reproductive during human history. once consumed, they're gone forever.

if they were to be exhausted before we could find sufficient reproductive resources to replace them with, we'd have to live in entire blackout again like our ancestors have done thousands of years ago. that's of course not what anyone would want to see.

due to technical limitations, people still have to utilize these resources now.

as a result, we must economize them most cleverly. new techniques should be developed and applied to reduce energy cost in industry and daily life. alternative energy should be employed wherever possible. eradicate any practice that wastes energy.

humans have overcome so many crises in history, and we're sure to win this time also.

新一轮的能源危机是敲门。2004年,全球石油消费达到了一个新的记录,导致了在国际市场上石油价格的飙升令人惊讶。

至于中国,据报道,许多传统的矿物在中国东北城市陷入困境,他们的经济崩溃和工人失业,只是因为煤炭被开采出来。

化石能源资源,包括煤炭、石油和天然气,不像阳光,水力和风力发电产生的一致。他们不是几乎在人类历史上繁殖。一旦食用,它们一去不复返了。

如果他们筋疲力尽之前我们能找到足够的生殖资源来替代它们,我们必须生活在整个停电又像我们的祖先几千年前。这当然不是任何人想要看到的东西。

由于技术的限制,人们现在仍然需要利用这些资源。

因此,我们必须节约他们最聪明的。应该开发和应用新技术降低能源成本在工业和日常生活。应尽可能使用替代能源。消除任何浪费能源的实践。

人类历史上已经克服了很多危机,我们这次也一定会赢得。

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.
