Solar energy captured by solar panels is a limitless form of energy, as the earth is bombarded with extreme amounts of solar energy every day, according to the National Renewable Energy Laboratory. It's also clean, producing no carbon dioxide, and is very low-maintenance, since solar panels have no moving parts.

Unfortunately, the National Renewable Energy Laboratory says its high installation cost makes it up to four times more expensive than the cost of electricity from a standard utility company. For optimal operation and maximum energy production, it requires year-round sunny weather and is very expensive if repair is necessary, according to the U.S. Environmental Protection Agency

Năng lượng mặt trời thu được bởi các tấm pin mặt trời là một dạng năng lượng vô hạn, vì trái đất bị bắn phá với lượng năng lượng mặt trời cực lớn mỗi ngày, theo Phòng thí nghiệm năng lượng tái tạo quốc gia. Nó cũng sạch sẽ, không tạo ra khí cacbonic và bảo dưỡng rất thấp, vì các tấm pin mặt trời không có bộ phận chuyển động. Thật không may, Phòng thí nghiệm năng lượng tái tạo quốc gia cho biết chi phí lắp đặt cao của nó làm cho nó đắt hơn gấp bốn lần so với chi phí điện từ một công ty tiện ích tiêu chuẩn. Để hoạt động tối ưu và sản xuất năng lượng tối đa, nó đòi hỏi thời tiết nắng quanh năm và rất tốn kém nếu sửa chữa là cần thiết, theo Cơ quan Bảo vệ Môi trường Hoa Kỳ

Nowadays, more and more people choose to live in the city. In this essay, I will discuss about the advantages and disadvantages of living in the city.

It can't be denied that living in the city has many benefits. First of all, if we live in the city, we will have many chances get the developing science and technology. It means that we will have more job opportunities and broaden our knowledge more easily. Secondly, we will have many different ways to spend our free time. There are a lot of theatres, concerts and other kinds of entertainment. There is always a lot to do and visit There are a lot of possibilities of shopping. In various shopping centres and galleries you can buy whatever you want. What is more, a big city is a potential market for trading activities, so we can earn more money to provide our family a comfortable life

Besides advantages, living in the city brings to us a lot of disadvantages. Firstly, a problem about which everyone is worrying is environment. The increase of factories based on industrialization and modernization has severely polluted environment. Smoke from factories' chimneys not only pollutes the air but also makes people get many serious cancers. Sewage is bumped into rivers without being purged, which threatens underwater ecosystems. The second drawback of living in the city is society's vices such as drug addiction. Young people. especially the students, are easily spoiled by bad habits. If people use up all the money, they can't control themselves and even become robbers or murders. Moreover, a problem that many people living in the city have is heartlessness. With some people, it's not worth being worried and it has no effect on our life, people are too busy to care for any others. But if more and more people become heartless, the society will be worse, no one cares another one, they live boring lives, every purposes became meaningless, without love, sympathy and many other good things.

There are good things as well as bad thing of living in the city. However, I strongly believed that advantages outweigh disadvantages. If people know how to live and enjoy their life, living in the city is one of the most interesting things that people want to experience.

             THE ADVANTAGES AND DISADVANTAGES OF SMART CITIES

     Smart cities are built on new technologies to improve people's lives. The idea of living in one of them sounds very exciting. But is a life controlled by smart technologies good or bad for us?

     Let’s start with the advantages. One of the biggest advantages of smart cities is the high level of convenience they offer. With smart technologies in place, people can access information and services quickly and easily. This makes daily life more efficient and saves people a lot of time. Additionally, smart cities are designed to be more sustainable, with green spaces and public transport options to reduce pollution.

     What about the disadvantages? One of the main concerns people have about smart cities is the potential loss of privacy. With sensors and cameras constantly monitoring people's movements, there is a risk that sensitive information could be collected and shared. This can lead to a lack of trust and a feeling of being constantly watched. Furthermore, there are concerns about the potential for technology failures and the risks posed by hackers.

     In conclusion, there are both advantages and disadvantages of living in a smart city. In my opinion, the benefits of smart technologies outweigh the drawbacks. However, it is important that measures are put in place to protect people's privacy and ensure the safety of their personal information. As long as these concerns are addressed, smart cities have the potential to revolutionize the way we live and work.

The Internet plays an important role in our modern life. However, every coin has two sides and we can find out pros and cons of the internet by my following provement.

The Internet is a breakthrough in developing technology. It brings us wonderful advantages. First, education is more and more improved due to appearance of the internet. Students can learn and look for basic knowledge online without spending too much time in the libarary. This leads to the fact that it is very convenient for both teachers and students to broaden their perception. Second, the internet shorten the distance of people even though they are very far from each other. Skype or Yahoo are good ways for them to contact and have fun. It is true to say that distance is not a big problem in such a developing technology world. Third, the internet makes everything easier and faster. For example, we can send or receive documentary through email for a short time wwhile 10 years ago, we need to wait foe 3 or 4 days to send to a far distence.

On the other hand, the internet also has drawbacks. People especially teenager are easily involved in computer games. They take so much time to sit in front of the screen to play games. This doesn't only affect to their health but it also decrease the amount of money which their parents earn by hard works. They can't understand that money doesn't grow on tree. Moreover, the internet prevents them from taking part in outdoor activities beacause of the internet's attraction. This will slowdown socal skills and cause their inconfidence .

In a word, the inetrnet is one of the most wonderful inventions in the world. However, it also causes trobles in our life. Thus, we should use it in moderate

The world is developing day by day, and one of its biggest invention is the Internet. The first adventage of the Internet is that it changed our life style. While in the past, people had to go to the supermarket to buy what they wanted or they had to visit the park for entertainment, now we only need to stay at home with a phone connected to Internet, we can easily buy anything or can relax with video games. However, it is also a disadvantage. Some people spend too much time on it, this can do harm to our health and our eyes. Therefore, although the Internet is usefor for us but we should spend little time surfing it.

Nowadays, large cities are becoming more and more inhabited. The majority of the population prefer living in a big town mainly because of the great advantages it has compared to living in the countryside. However, what are the benefits of this situation, and what are the drawbacks? In this essay, I will explore the pros and cons of living in a large city and try to draw some conclusions.

Let’s start looking at the advantages. One of the main positives of a big town is the large amount of shops available in every corner of the city. What I mean by this is that whenever you live, there are some useful stores supermarkets, banks, tobacconists and clothing stores where you can easily buy everything you need without going to the city center. Secondly, living in a big town is a big challenge for evening parties. In London, for example, there are so many things to do in the evenings going to the cinema, to the pub or to the park during the summer period.

Turning to the other side of the argument, traffic could be one of the major disadvantages of living in a big city. Many people take the car everyday and it has also been proved that the majority of the families have at least two cars. This means that you have to deal with rush-hour traffic on your way to work and on your way back. In addition, in a big town there is consequently a lot of smog and this can really affect people’s health.

To sum up, living in a big city has great advantages but also some significant negatives.You have to weigh up to the pros of enjoying evenings’ nights outside and the availability of many shops and the cons of cope with smog and traffic issues. Personally, I believe that the benefits of enjoying the city-life and the comfort of having shops at every corner, eventually overweigh the negatives.
