▶ Your Answer : Both the passage and the professor discuss about whether hydrogen energy is an appropriate alternative energy source or not. While the passage maintains that hydrogen energy is a pleasing new source, the professor contends that hydrogen energy is inappropriate.
To begin with, the passage states that hydrogen energy can be obtained easily because it is a plentiful resource. Moreover, hydrogen energy is more affordable than nonrenewable sources, which is about to exhaust soon. On the other hand, the professor asserts that hydrogen energy is not as cheap as people believe because the cost of splitting hydrogen with electricity actually costs a significant amount of money.
Secondly, the passage claims that hydrogen energy, as well as the method of splitting water, is eco friendly because it uses other renewable energy, not producing any harmful emissions. Nevertheless, the lecturer argues that the method actually places adverse effects on the environment because the method requires electricity. Moreover, the method of using renewable powers, such as sun and wind, is not a feasible method because the weather is uncontrollable.
Finally, the passage mentions that hydrogen is easy to store and transport. Not only this, the new technology can remove the volatile resources and combine other elements. On the contrary, the lecturer rebuts by stating that it is, in fact, not easy to store. What's more, the stage of transforming hydrogen is a very tedious task because hydrogen is very volatile and it ignites fast. Besides, the alloy is unfeasible because of its heavy weight.
