We need energy to live and work. Our major source of energy is oil. Oil is one kind of fossil fuel. The amount ot fossil fuels in the world is limited. Therefore, we must save it, and at the same time, we must find new sources of energy. Geothermal heat and nuclear power are alternative sources of energy. They can give us electricity. Other alternative sources are the sun, waves and water. These sources are not only unlimited and available but also clean and safe for the environment. People should develop and use them more and more in the future.
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure.
Coal gasification can be used to produce syngas, a mixture of carbon monoxide (CO) and hydrogen (H2) gas. . The use of coal as fuel causes adverse health impacts and deaths. Coal mining and coal fueling of power station and industrial processes can cause major environmental damage.

Cho bạn nào có câu hỏi giống mình mà vẫn chưa tìm được câu trả lời. Solar energy brings us both benefits and drawbacks. One of the biggest advantages is that it is a renewable energy source. Energy can be produced as the sun lasts forever. Therefore, solar energy can really be called as a long- term energy source. Furthermore, that is a non- energy source of pollutants such as zero carbon dioxide or other gases in electricity generation. Beside those benefits, solar energy also has some drawbacks. The initial installation cost of solar cells is quite high, so not all people can use it. Also, it can not effectively work in cold weather due to the scarcity of sunlight. In conclusion, we can't deny the advantages of solar energy, but it still exists some disadvantages.

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.

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.

+ Advantages of solar energy:
One of the biggest advantages of solar energy is that it is a renewable energy source. Energy can be produced as long as the sun lasts, which is millions of years. Therefore, solar energy can really be called as a long-term energy source.
-As direct electricity develops from solar energy, there is no scarcity of raw materials, i, sunshine. It is found in abundance.
-The solar cells are very easy to install, can be installed on the roof and so no extra space is needed. Generation of energy at a small scale, on the basis of individual users
-The solar panels are not noisy and stationary. They also require very little maintenance.
-Solar energy can be produced in any part of the world, in any place where more sunlight is available.
One of the most important environmental advantages of solar energy is that it is a non-energy source of pollutants such as zero carbon dioxide or other gases in electricity generation.
Due to the above reasons, solar energy is not dangerous to the environment and therefore, is also known as a clean energy source.
When thinking about the economic advantages of solar power, then one should note that in addition to the initial installation costs, solar generation and use is free. No charge, the bill to tend to!
- Coal, natural gas and petroleum and other fossil fuels tend to increase continuously. Solar, on the other hand, is free.
-Solar energy can be used to cook, heat water, and also to operate various electrical appliances based at home or office.
- Finally, one of the other major benefits of solar power is that this renewable energy is healthier, safer and easier to use at home, on the office or on a large scale.
-Now you know what are the advantages of solar power, you have to wonder is there any difficulty or defect of solar energy? Then the answer is yes, there are some negative aspects of the source of energy. Tell us more about it.
+ Disadvantages of solar energy
-The initial installation cost of solar cells is quite high. However, a need to invest only in installation and then electricity is free.
-Solar energy can not effectively work in cold water due to the scarcity of sunlight.
-For large-scale applications, larger area and higher investment is needed, which can not be met easily.
Solar energy makes us have solar electricity, light to live. If you don't have solar energy, you will have to use electricity, but using electricity will cause a fire, so solar energy is very good

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.

(Một số từ mk tra Google dịch đấy. Không biết có sai ko mong bạn sửa giùm mình. Hì Hì)
At present, most of our energy comes from fossil fuels (coal, oil and natural gas). However, reserves are limited. Because demand for electricity is rising rapidly, fossil fuels will be exhausted in a relatively short time. Therefore, people must develop and use alternative energy sources.
An alternative energy source is nuclear power. Nuclear power can provide enough electricity for the needs of the world for hundreds of years, but it can be very dangerous. An alternative source of geothermal energy comes from deep within the earth. Scientists use heat to generate energy. However, this energy is only available in some parts of the world.
Sun, water and wind are alternative sources of energy. Wind rotating the windmill and moving the sailboat. It's a clean source and a lot of energy. Unfortunately, if the wind does not blow, there is no wind energy. As water moves from one place to another, it makes energy. However, people have to build dams to use this energy source. The dams cost a lot of money, so water is expensive too.
The sun releases large amounts of energy each day. This energy can be converted into electricity. Many countries use solar energy for their daily lives. Solar panels on the roof can generate enough energy to heat or cool the entire home. Solar energy is not only abundant and infinite but also clean and safe.
Despite some drawbacks, the potential of alternative energy sources is enormous. However, how to make full use of the energy resources is a question for researchers all over the world.

Hiện nay, phần lớn năng lượng của chúng ta là từ nhiên liệu hóa thạch (than, dầu và khí tự nhiên). Tuy nhiên, trữ lượng còn hạn chế. Do nhu cầu điện tăng nhanh nên nhiên liệu hóa thạch sẽ cạn kiệt trong một thời gian tương đối ngắn. Do đó, người dân phải phát triển và sử dụng các nguồn năng lượng thay thế.
Một nguồn năng lượng thay thế là điện hạt nhân. Năng lượng hạt nhân có thể cung cấp điện đủ cho nhu cầu của thế giới hàng trăm năm, nhưng nó có thể rất nguy hiểm. Một nguồn năng lượng địa nhiệt thay thế đến từ sâu trong lòng đất. Các nhà khoa học sử dụng nhiệt để tạo ra năng lượng. Tuy nhiên, năng lượng này chỉ có ở một số nơi trên thế giới.
Mặt trời, nước và gió là những nguồn năng lượng thay thế. Gió xoay cối xay gió và di chuyển thuyền buồm. Đó là một nguồn sạch và rất nhiều năng lượng. Thật không may, nếu gió không thổi, không có năng lượng gió. Khi nước di chuyển từ nơi này sang nơi khác, nó làm cho năng lượng. Tuy nhiên, người ta phải xây đập để sử dụng nguồn năng lượng này. Các đập tốn rất nhiều tiền, vì vậy nước cũng đắt.
Mặt trời phát ra lượng năng lượng lớn mỗi ngày. Năng lượng này có thể được chuyển thành điện. Nhiều quốc gia sử dụng năng lượng mặt trời cho cuộc sống hàng ngày của họ. Các tấm pin mặt trời trên mái có thể tạo ra đủ năng lượng để sưởi ấm hoặc làm mát toàn bộ ngôi nhà. Năng lượng mặt trời không chỉ phong phú và vô hạn mà còn sạch sẽ và an toàn.
Mặc dù có một số hạn chế, tiềm năng của các nguồn năng lượng thay thế là rất lớn. Tuy nhiên, làm thế nào để tận dụng các nguồn năng lượng là một câu hỏi cho các nhà nghiên cứu trên toàn thế giới.
