C2:Năng lượng tái tạo hay năng lượng tái sinh là năng lượng từ những nguồn liên tục mà theo chuẩn mực của con người là vô hạn như năng lượng mặt trời, gió, mưa, thủy triều, sóng và địa nhiệt.. Nguyên tắc cơ bản của việc sử dụng năng lượng tái sinh là tách một phần năng lượng từ các quy trình diễn biến liên tục trong môi trường và đưa vào trong các sử dụng kỹ thuật. Các quy trình này thường được thúc đẩy đặc biệt là từ Mặt Trời. Năng lượng tái tạo thay thế các nguồn nhiên liệu truyền thống trong 4 lĩnh vực gồm: phát điện, đun nước nóng, nhiên liệu động cơ, và hệ thống điện độc lập nông thôn

Dear Oanh,Thank you very much for your letter which arrived a few days ago. It waslovely to hear from you. I am sorry, I haven’t written for you such along timebecause I studied hard to pass the final exam. However, I had agreat weekendmore than every when I went to live concerts last night with my friends.

Good Evening, everyone. I'm ... and today I'm going to tell you how to save energy

Most of us use too much energy. You can reduce this amount by :

- Switch off or unplug any chargers or appliances you don’t need on.

- Use energy saving lamp

- Switch to renewable energy sources
If you follow these simple rules, not only you will seve energy, but also reduce global warming

Nowadays, energy is being run out more and more so it is one of the most important things of our life. We need to save energy because nobody of us can lives without energy. So why don't we start to do it right in our home? We have many ways to save energy in our home. One of those ways is using electricity, water and gas economically. Such as we should turn off the light in room when we go out or in unnecessary situations, avoid wasting water, shut the kitchen stove when stop cooking. Use a microwave instead of a stove to reheat food. Use rechargeable batteries instead of disposable batteries... Besides, we should use electrical equipments which are energy - saving. Such as using lights and fans that have low capacity, or using equipments which reserve electricty. Not only do these help us to save money but also they work effectively.
In addition, we should frequently check electrical equipments in our home in order to fix opportunely. In summary, we need to save energy so that energy isn't run out and continues to serve human's life.

The environment plays an important important in our life.However nowaday environment is becoming polluted by some following reasons
Firstly some people aren't a ware of protecting the environment .Fox example garbage is thrown everywhere Moreover the deforestation still happens in many countries .
Secondly our environment is polluted by exhaust fume from factories and vehicles so the local authorities should prohibit and fine heavily the factories that populle the environment.Beside that we don't cut down trees,we should plant trees to protect the forest

Enviroment is neccessary thing for this life. Enviroment is the air we breath, the water people drink and is everything they need for their life. But now the most important thing for the life is being polluted. This pollution affects the health of all living things. Air is damaged by lorry fumes and car, and power stations create acid rain which can destroys entire lakes and forests. When fossil fuels: gas, oil and coal are burned to provide energy for cooking, lighting etc. they form polluting gases. Not only on land but also in the sea, oils spills pollute sea water and kill marine life; chemical waste from sewage works and factories, and artificial fertilisers from farmland, pollute river water, spreading disease, and killing wildlife. Everything is being caused by human’s existence. Humans create rubbish! Each household produces about one tonne of rubbish each year! Most of this is taken away by dustmen and burned in incinerators or buried in enormous landfill sites – both of these actions can be dangerous for our environment.

But only people can change and solve it. Pollution could be prevented by all thing we do each day. First people can use recycled paper to save trees. Second try to avoid using plastic. It is hard to recycle. People should refuse to use carrier bags. If people can not avoid buying plastic bags, they should use re-use plastic bags many times. Finally people must take their old clothes to charity shops. People also should save energy to protect environment. Switching off all electric things when they are not in use, walk or use a bicycle instead of car for short trips, keep healthy life and keep clean atmosphere.

Keep clean environment isn’t only all ways are mentioned before but also to protect natural resources. That is the way to conserver wild life. First we need to conserve the old forest, rainforest, build more safari and national park, and plant more trees to make place to live for wild animals. Second we need to prohibit hunters who hunt animals too many out of the law allowance.

Finally, we now know that enviroment is the most important thing for life and we know how to protect and use it scientifically. Everyday we invent and find more and more way to protect enviroment. I hope that in the future the earth will be cleaner.

Hi everyone! My name is An and today I’m going to give you some useful information about how to save water at home.
Well, we all know that water is an integral part of our life; thus, we cannot stop using it but just reduce the amount of water we use daily. These following tips will help us to cut down on water waste.
Firstly, we should regularly check faucets, pipes and toilets for cracks to ensure that any leaking toilet tanks or dropping taps are fixed as soon as possible. Secondly, don’t forget to turn off the taps while we are brushing our teeth, washing our face or getting a shave as we can save up to 5 liters of water per minute. Thirdly, having a shower uses much less water than bathing in a bathtub, so try to take a shower every time you can. Another tip is to run washing machines and dishwashers only when we have enough dirty clothes and dishes for full loads. Lastly, never think of using the toilet as an ashtray or a wastebasket for cigarette butts, facial tissues, tea bags and other kinds of small trash because flushing these items can waste about ten liters of water each time.
It can be concluded that these five simple actions help us save water, save our own money and prevent water pollution as well.

Electricity saving is a very good job, the media and people mentioned a lot on the news, books, newspapers .... But few do this job. Electricity saving has a very common theme: "Shutting down when not in use" and at the same time it is also a way to save electricity. There are still a lot of ways to save on electricity: buy household appliances that consume less electricity, do not use more electronics at home at the same time, ... Let's join hands to save energy. light !

We are now facing the excessively increasing consumption of energy all over the world. It is predicted that global energy consumption will rise nearly sixty percent in the next twenty years. This rise is caused by some factors such as population growth, urbanization, and economic and industrial expansion. Seeking cheap, clean, effective sources of power, some countries are hopeful of being able to produce part of their electricity with renewable means such as wind or solar power. On a cloudy day in Britain, a solar roof can generate enough electricity for the household to play 140 hours of TV and make 35 cups of tea. One kilowatt of solar energy can save up to a ton of CO₂ emissions each year. Solar panels and wind generators help to provide alternative sources of energy for private homes, and they are no longer too expensive. These renewable energy systems can lead to big savings for households in the long run and in Britain the government is providing financial help with the cost of installing them. In addition to the use of renewable energy sources, human beings now know how to save energy more efficiently. Companies make electrical equipment which is environment-friendly and money-saving. Refrigerators, washing machines, tumble dryers and other home appliances are labeled to help consumers compare the energy efficiency of each model with other appliances in the same category. Households also try to save energy in whatever way. Ordinary light bulbs are replaced with energy-saving bulbs. Having a shower instead of a bath becomes more common. TVs, electric fans and air conditioners are turned off when they are not in use. Those are simple actions but they contribute significantly to the energy saving movement. In a nutshell, using renewable energy sources and saving energy at home not only saves money but also protects the Earth’s resources.

How to avoid waste of energy?

With fast growth of civilization there is also an ever mounting need for energy. Energy may be in the form of fuels or electricity. Petrol is a liquid fuel which is used widely nowadays. But this kind of fuels is likely to be exhausted at the rate man is using it recently.

To meet the challenge, various methods have been suggested. One is to minimize the man’s demand in using the energy. Non-essential consumption should be minimized. During certain days of the year, people all over the world turn off the electricity for 1 hour to save the energy. Modern gadgets consuming energy should only be used when they are absolutely necessary.

Energy conservation is possible through modernization of plant and equipment. People should replace the obsolete equipment by the modern ones.

Energy can be saved on transport by the following methods. People should commute by the rail rather than by cars and vans. The transport must be improved with a view to sparing the energy. Cities must be planned in such a way that the commuting distance from this place to others is minimized.

In industry, many things could be done to reduce waste of energy or to economize energy. The machine maintenance needs to be tightened; heater must be utilized properly. When systems are streamlined, economy in fuel is obvious. Instead of using materials requiring higher energy, those which require lower energy should be used.

We hope man with his ever rising urge for existence will cope up with this urgent problem and find alternatives.
