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.

Paragraph:
The Earth is gradually running out of resources. Resources are scarce day by day, so scientists are researching and looking for new resources. In temperate countries, due to have many the wind, the wind is used to generate electricity. In tropical countries, due to having much sunshine, the sunshine is used to generate electricity. And a lot of countries in the world use different resources instead of using water to generate electricity.
Traslate:
Trái đất đang dần cạn kiệt tài nguyên. Nguồn tài nguyên khan hiếm từng ngày, vì vậy các nhà khoa học đang nghiên cứu và tìm kiếm những nguồn tài nguyên mới. Ở các nước ôn đới, do có nhiều gió nên gió được dùng để sản xuất điện. Ở các nước nhiệt đới, do có nhiều ánh nắng mặt trời nên ánh nắng mặt trời được sử dụng để phát điện. Và có rất nhiều quốc gia trên thế giới sử dụng các nguồn tài nguyên khác nhau thay vì chỉ sử dụng nước để tạo ra điện.

Đây nhé bạn! bạn học chương trình mới phải không? Thế thì chắc đoạn văn này bạn sẽ hiểu một cách dễ dàng!
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.

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.
Translate into English
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.
_ Good luck _

Solar, light and heat radiation from the sun, has been exploited by humans since ancient times using a growing array of technologies than ever before. Solar radiation, along with secondary resources of solar energy such as wind and wave power, water and biomass, make up most of the renewable energy available on Earth. Only a very small fraction of the available solar power is used.
Solar power means generating electricity based on heat and photovoltaic cells. The use of solar energy is limited only by human ingenuity. Partial list of solar applications space heating and cooling through solar architecture, through distillation of drinking water and sterilization, daylight illumination, solar hot water , Solar cooking, and high temperature process heat for industrial purposes. To collect solar energy, the most common way is to use solar panels.
Solar technology is widely described as either passive solar or active solar energy depending on how they capture, convert and distribute solar energy. Active solar engineering involves the use of photovoltaic panels and solar thermal power to harness the power. Passive solar engineering involves orienting a building towards the sun, selecting materials with favorable heat mass or dispersed light property, and designing natural air space.

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.
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.
