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.

In modern times, our continued advance in technology has led to the explosion of many useful electronic devices, one of which is mobile phone. It has become a vital part of people’s life on account of the huge benefits it brings. To begin with, mobile phone is a source of information. With Internet access available anywhere and at any time, users can search for the latest news and keep themselves informed of events around the world. Not only providing information, it also acts as a useful device for storage. Photos, videos, records or texts can all be stored in your phone. For instance, when you attend a lecture but seem to be not quick enough to take note everything, it is possible to record it and play back several times. More than that, the important function making it increasingly appealing nowadays is a source of entertainment, offering people with a wide range of activities in the free time such as playing games, listening to music or reading e-books. Last but not least, mobile phone has been upgraded to become a multifunctional device, which can come in handy in different situations. Many cell phones often come with a GPS and a Map application, allowing users to identify their location and get the right way to the place they want. To sum up, mobile phone is undoubtedly one of the greatest inventions, which not only meet the demand for communication, information exchange and entertainment but also offers numerous useful functions that make our life easier.

Modern society is constantly developing, and the appearance of the Internet has opened up a whole new era of access and sharing of information. This brings a tremendous reform and benefits to all humanity. In our lives there are innumerable questions that need to be answered, and the Internet was born as a useful tool to help us solve those questions. Searching for information in the past has cost humanity a lot of time and effort, and not everyone had patience to turn the pages one by one to find the information they needed. However, our lives have changed tremendously since the arrival of the Internet, and the search of general information on the Internet has not consumed us much more than mouse clicks and keyboard typing. This is where most basic and specialist information is gathered from the majority of occupations and fields in our life. There are countless websites that contain useful information for research and study, and Wikipedia is now considered to be the most complete and accurate encyclopedia. Searching the Internet is simple, but we should also be careful in getting that information. Not all knowledge on the Internet is accurate and complete, so we need to compare information from many different sources before actually using any of them for our purposes. The Internet is an infinite ocean of knowledge, and we can learn countless things if we know how to use it properly.

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.
