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 unrealiability of sources.

2. Use the ideas in the following boxes to write an essay of 180-250 words about the advantages and disadvantages of consuming organic food, using the outline of the essay in 1. (Sử dụng ý tưởng trong các hộp sau đây để viết một bài luận của 180-250 từ về những ưu điểm và nhược điểm của tiêu thụ thực phẩm hữu cơ, sử dụng những nét chính của bài luận trong 1.)

Nowadays, food safety issues are regarded as one of the most important problems people, especially those in developing countries, have to face. As a result, consumers tend to pay more and more attention to the organic food. Some think it should be widely promoted while others assume it has certain limitation when in use based on its advantages and disadvantages.

First of all, organic food is very clean and safe for people’s health because there are fewer chemicals or pesticide sprayed on it. Consequently, consumers will have more chances to use nutritional foods without any doubt. In addition, farmers use eco-friendly methods to cultivate so they spend fewer expenses on farming and are able to make big profits from selling their products.

In contrast, organic food has its own limitations, particularly for people with certain financial and geographical conditions. Producing organic products takes a lot of time and efforts and depends on many farming conditions such as suitable lands, weather, and farming methods. Accordingly, the price of organic food is quite expensive and buyers have fewer choices in favourite foods.
