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.
Energy is very important in our daily life. We use energy for almost everything we do. However energy is limited. We should do the following things to save energy. Firstly, we should use electricity more efficiently. Secondly, we had better reduce our electricity bills. Besides, it’s necessary to turn off the lights when leaving a room or before going to bed to save energy. Moreover, we ought to reduce the use of fossil fuels. In short, we should try our best to save energy for our future and for our planet’s future.

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.

+ 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.

I only know one paragraph.
Nowadays, due to the shortage of energy, the use of green technology from renewable resources such as wind, sun and water is becoming more and more important and urgent.
Among these green energy resources, energy from the sun or so-called solar energy is considered to be the most available one.
First and foremost, solar energy comes directly from the sun which is an abundant source of renewable energy. Thus, it is sustainable. Besides that, thanks to its natural source, this type of energy is environmentally friendly and does not cause pollution. Furthermore, solar energy is available everywhere in the world, especially in countries near the Equator. Additionally, its devices, such as solar panels do not have moving parts and are very quiet to operate. However, the implementation of solar energy consumption has its own drawbacks.
First, it costs lots of money to operate. Solar panels are expensive to produce because they are made from rare and special materials. The technology used to store solar energy is also costly. Secondly, though the sun is available everywhere, the access to sunlight is limited at certain times, such as on rainy days or in the evenings. What's more, although solar energy is greener than fossil fuels, the production of solar panels may cause greenhouse gas emissions. In conclusion, there is no known energy that is totally safe and perfect to use. It is expected that in the near future, new green technology will be developed to reduce or eliminate the disadvantages that are mentioned above.
Television is a breakthrough invention of human, however, it has both advantages and drawbacks. First, take a look at its benefits. TV is a huge source of information with a wide variety news and instruction channels. You now can learn through TV and update news about what is happening in the world. Television also provides a huge knowledge of many fields including natural science, social science,… Besides, Television is a common type of entertainment thanks to a wide range of music TV programs, cartoons, reality shows or funny programs. On the other hand, television has some outstanding disadvantages. In fact, many people become addicted to Television and turn it on all day. Especially to children, they don’t want to go out to play with friends or focus on study. They just sk their eyes to the screen without wanting to leave. Some programs even contain violent and criminal content, which influence negatively on children. Also, spending hours watching TV is harmful to your eyesight and wasting your time. With that amount of time, you can do something more beneficial such as playing sports, doing physical exercises or learning new skills. In summary, nowadays, television is indispensable and its benefits outweigh its drawbacks.
Energy is very important in our daily life. We use energy for almost everything we do. However energy is limited. We should do the following things to save energy. Firstly, we should use electricity more efficiently. Secondly, we had better reduce our electricity bills.

Viết 1 đoạn văn ngắn về thuận lợi và bất lợi của 1 nguồn năng lượng.
Nhớ ngắn thôi nhé! Cần gấp lắm!
Hydro power is plentiful and it can generate a great deal of energy. However, hydro power is limited because we cannot build dams in some certain areas.
n our daily life, energy play a very important role, so we should save energy. I think there are many ways to save energy and now I will share with you some ways to save energy effectively. Firstly, we should turn off all the electric appliances when we don't use them such as: lights, fans, air conditioner...… Secondly, we can use solar energy or wind energy instead of electric energy in our house. It will help us save more money. Thirdly, we can go to school or go to work on foot, by bike or by public transport instead of motorbike or car. By these ways, the energy will be saved.

Trong cuộc sống hằng ngày của chúng ta, năng lượng đóng một vai trò vô cùng quan trọng, vì thế chúng ta nên tiết kiệm năng lượng. Tôi nghĩ có nhiều cách tiết kiệm năng lượng và bây giờ tôi sẽ chia sẻ với các bạn một số cách tiết kiệm hiệu quả. Đầu tiên, chúng ta nên tắt tất cả những thiết bị điện khi không sử dụng như đèn, quạt, điều hòa…. Thứ 2, chúng ta có thể sử dụng năng lượng mặt trời hay năng lượng gió thay cho điện ở trong nhà của chúng ta. Nó sẽ giúp chúng ta tiết kiệm được rất nhiều tiền. Thứ 3, thay vì đi ô tô hay xe máy, chúng ta có thể đi bộ đi học hoặc đi làm. Bằng những cách này, chúng ta có thể tiết kiệm được rất nhiều năng lượng.
