Đoạn văn tiếng anh thuận lợi và bất thuận lợi của sử dụng năng lượng mặt trời

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. This essay will discuss both pros and cons of using solar energy. 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.
