The reading passage and the lecture discuss various aspects concerning hydrogen energy’s efficiency. For the most part, While the reading passage states that hydro energy will make positive effect on our society, (이 서술과 energy efficiency의 관계는? 서론의 첫 두 문장이 너무 동떨어져 보입니다. 두 글의 주제가 1) 수소 에너지의 효율성인지 아니면 2) 수소 에너지가 우리 사회에 좋은 영향을 줄 것이라는 것인지 아니면 3) 수소 에너지가 효율적이기 때문에 좋은 영향을 줄 것이라는 것인지? 정리가 필요합니다.) the lecturer claims that the suggestion in the reading passage is unfounded due to the following three reasons.
The first point made by the reading passage is that hydrogen is a plentiful element on Earth, so hydrogen energy is much cheaper than fossil fuel which will be depleted in the future. The lecturer, however, challenge this viewpoint by arguing that the cost of generating hydrogen energy is not cheap. He says the production cost of hydrogen energy (비싼 건 공기 중에 널려있는 수소가 아니라 그 수소를 가공해서 에너지로 만드는 과정이죠!!!!) is more expensive than that of gasoline.
The next point of the reading passage is that hydrogen energy is environmentally friendly. On the other hand, the lecturer claims that since electricity is needed to obtain produce hydrogen energy, it can not be said hydrogen energy is eco-friendly. Also, renewable source of energy to obtain hydrogen is not always possible. (어떤 주장인지 더 설명이 필요해보입니다.)
Finally, it is stated in the reading that hydrogen is easy to store and transport. In contrast, the lecturer argues that hydrogen is really difficult to deal with. This is because hydrogen is volatile and hydrogen alloy is too heavy to carry.
