Ever since early this century, electricity has become an essential part of our modern life. It plays an important role in many fields such as industry, agriculture and the daily life of men. Electricity is a source of energy that makes it possible for the factories to turn out products and for people to create comfortable living conditions, for example.
If there were no electric power, things would be quite different. Machines could not run and people would have to fall back on their hands to produce what is essential for them to keep alive. Traffic would have to stop at night because there would be no lights in the street. A world in darkness would no longer be a pleasant one. In a word, things would be in a mess.
Therefore, we should realize the importance of electricity. As electricity is insufficient in our country, we should be frugal in using electricity. We should make great efforts to produce more electricity.
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.
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.
china is rich in various energy resources. coal and petroleum, for instance, are two major trees. they ave essential in developing the country's industry, ,science and technology. china has done a great deal in the past few decades to raise the output of coal and petroleum.
these energy resources are being used up rapidly, however. with the building of four modernizations, new industrial and science projects axe springing up like bam booshoots after a spring rain. they are all enormous consumers of energy resources. be sides, there has been great waste in using these resources.
to avoid energy crisis in the future, the government must take measures. first, it should let the people know, through education, the importance of ,saving energy. sec ond, efforts should be made in opening up new energy resources, such as solar energy, geothermal energy and so on. we have reasons to be optimistic in this respect.
Another round of energy crisis is knocking at the 2004,world oil consumption reached a new record,causing oil price in the international market to skyrocket 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 ’re not practically reproductive during human consumed,they’re gone 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 ’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 techniques should be developed and applied to reduce energy cost in industry and daily rnative energy should be employed wherever icate any practice that wastes ns have overcome so many crises in history,and we’re sure to win this time also.
China is rich in various energy resources. Coal and petroleum, for instance, are two major ones. They are essential in developing the country's industry, science and technology. China has done a great deal in the past few decades to raise its output of coal and petroleum.
Three energy resources are being used up rapidly, With the building of four modernization, new industrial and science projects are springing up like bamboo shoots after rain. They are all big consumers of energy resources. Besides there has been considerable waste in the utilization of these resources.
To avoid an energy crisis in the future, the government must take certain measures. First, it should let people know the importance of saving energy. Second, efforts should be made to develop new energy resources, such as solar energy, geothermal(地热) energy and so on. We have reason to be optimistic in this respect.
As a result of greenhouse effect and global warming,everyboby is to save energy and reduce the release,even Prince following tips may be helpful.
To save electricity,please turn off the lights when leaving the a minute when you‘re taking a ch off the water when using soap.
In summer,turn up the air-conditioner by one winter,turn it down by one er cut off the power after you turn off your puter and any other electrical appliances when ‘s advisable that you install a solar hot water supply system if you live on the top ough it cost some money,it will prove money ‘s suggested that you collect all the empty bottles and waste paper,and have them recycledSwarch the Internet for more information about carbon release reduction tips.
Let‘s save energy so that we can prevent this planet from being another Venus or Mars!
Since scientists discovered the principle of electricity, electricity has become an indispensable source of energy in less than 200 years. We can use electric lights, TV sets, washing machines, refrigerators, computers and other appliances. With it; The night of the city is brightly lit, and the traffic accidents have been reduced. With it, we have a few happy and happy lives.
But according to scientists, earth's oil, natural gas, coal and other energy sources will end up being used up by humans, and even the most abundant solar energy will run out in a few decades. The car put out the fire, the electric light is not bright, the television is not the image and the sound, the computer is a decoration, this is what a terrible sight! It's almost the end of the world. China has limited energy. Therefore, energy efficiency must be mentioned.
Saving energy must start from me, starting from a little bit by the side, forming a good habit of turning off the light and water, the air conditioner should not be too low in summer, not endless listening to music and so on.
In short, in our life, such as food, clothing, shelter, line must depend on energy, to manufacture and use, so we should try to be a simple life, reduce any unnecessary waste, is the best way to save energy.
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.
