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.

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.

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.
