▶ Your Answer :
The reading passage contends that solar energy is a promising alternative source.
On the other hand the lecturer brings up several points that contradict this argument.
First the speaker argues that solar energy is not environmentally friendly. One significant reason is that it has to install solar panel which takes up much of a land. for example if it is installed in New-york city, it has to use more than 25% of land to install the panel. Therefore it is not efficient and damage environment.
This casts doubt on the reading which states that counters that solar energy does not destroy the environment.
Second, according to the lecturer, In order to store the energy, people must use battery. The material to make battery is rare. For example, the lead.
This refutes the reading passage's assertion that The resource is plentiful
The final points made by the lecturer is that located in remote area is not convenient to repair. What's more, to maintain solar system need high technology. This counters the writer's claim that Solar energy can work in remote area thus it has a lot of benefits. |
