Viết bài luận tiếng Anh về ưu điểm và nhược điểm của năng lượng xanh Lợi thế và bất lợi của năng lượng xanh

Tiếng Anh

As the world population is growing bigger and bigger, our energy demands are also growing. Governments and organisations have been trying to find new sources of energy to replace the fossil fuels which are running out. One of the solutions is to use green energy including solar, hydro, wind, geothermal, ocean and biomass. However, there are both advantages and disadvantages to this.

One major advantage is that they are renewable – they can be replaced naturally and cannot be seriously depleted. This green energy also reduces the cost of operation. As a type of clean energy, they emit little or no harmful chemical pollutants into the air, so they have a minimal impact on the environment.

While it is easy to see the environmental advantages of using green energy, we must also recognise some of the disadvantages. First, it is difficult to generate the quantities of electricity to satisfy our needs. Although the cost of operation is low, the initial cost of building and installing these new technologies are very high. Another disadvantage of using green energy is the unreliability of sources.

In conclusion, there are both advantages and disadvantages to the use of green energy. Hopefully, many of the disadvantages of these renewable sources of energy will be successfully removed through technological development and research, and they will be exploited fully to replace fossil fuels.
