The reading passage argues that the hydrogen energy is very attractive source as an alternative to fossil fuel by listing three merits of it. However, the lecturer claims that the hydrogen energy is not that promising
because it doesn't pass the testand he suggested the rebutting evidences of the merits.
To begin with, the lecturer contends that the hydrogen energy is not cost-effective source as huge barrier???장벽??장애물?? amount of electricity is required to produce the energy. Not only that,
assince controlling the weather is impossible, it is not very feasible to depend on sunlight to make it. Therefore, these findings efficiently contrast the reading passage's argument that the hydrogen energyiscan be cheaper than fossil fuel thanks to the wide availability,
On top of that, the lecturer asserts that the energy is not so environmentally friendly because electricity energy has to be used to produce it. Thus, this point refutes the reading passage's viewpoint that the hydrogen energy is not
isharmful to nature because it didn't make any harmful emission or by-product like other renewable sources.
Furthermore, the lecturer goes on to say that it is hard to store or transport the hydrogen energy source
assince converting the source to liquid or gas is very difficult, and the volatile form of it can be very dangerous. In addition, the solid form of it made alloy technologyistoo heavy to transport freely. These facts contract the reading passage's viewpoint that the hydrogen energy source is easy to save or transport.
