Task Overview

Professor

Energy source is vital for society's development. Some argue that we should use cleaner energy sources to protect the environment, while others believe traditional energy sources like coal and oil are better because they are less expensive. What is your opinion?

Student A

I think traditional resources are better than cleaner energy sources, because the price of traditional energy is low, which is conducive to the development of large-scale production. In addition, the technology for traditional energy is highly developed, and the use of traditional energy for production is profitable for improving production efficiency.

Student B

I prefer to think that we should develop new energy, which is good for improving the environment. Faced with severe environmental problems, the government must take environmental factors into account when making decisions. In addition, as technology improves, energy conversion becomes more efficient and less costly. Then new energy will have more advantages.

I believe that using cleaner energy is the better choice, since it does less harm to environment and able to provide a sustainable development. To elaborate, many scientists today are devoted in enhancing the quality of new-clear energy which is highly promoted to be utilized in advanced cars, manufactory industries. These effort has significant positive impact on mitigating air pollution and raising people's awareness of environmental protection. Contrarily, those traditional energy will not only does harm to air-quality but also contribute nothing to a sustainable energy industry since it will run out one day.
