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.

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.

+ 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.

Advantages of renewable energy
The first advantage of renewable energy is that it can be renewable, has an extremely large reserve, can be endless. Forms of energy such as solar, wind, geothermal, ocean waves, rain... are available and free to use, without fuel costs. Biomass energy also has large reserves and low fuel costs. Compared to traditional energy sources such as coal, oil, natural gas, which are increasingly depleted, only meeting human energy needs for about 50-70 years, this advantage is a strength. outstanding.


The second advantage of renewable energy is that it is abundant and can be widely exploited in all different areas of the earth. For example, with solar energy, people can exploit it anywhere, as long as there is sunlight, it can be used to generate heat to make hot water, heating, and generating electricity through the system. Solar power with solar panels… Or with wind energy, this energy source has been used for hundreds of years to move sailing boats, hot air balloons, windmills for irrigation systems. … or the current trend is to produce electricity from wind in many countries around the world.

Despite many great advantages, renewable energy also has some disadvantages, such as:

Due to the influence of nature, renewable energy is less stable than traditional energy sources. Solar energy can only be exploited during the day on sunny days, and at night or on cloudy and rainy days, the system will not work. Or with wind energy, wind turbines can only generate electricity at times when the wind speed is in the range of 4-25 m/s. Wind speed must be at least 4 m/s for the wind turbines to start running smoothly and generate electricity, but if it exceeds 25 m/s, the turbines will stop working to avoid damage in windy conditions. strong.

Requires advanced technology and high cost is also a drawback of renewable energy. To take advantage of renewable energy sources to generate electricity, it requires advanced technology and relatively high investment costs. Currently, the cost of electricity generation from renewable energy is generally higher than the cost from fossil energy. However, the development of renewable energy in the global trend has helped to reduce costs and increase efficiency, gradually improving this shortcoming.
