谢谢各位~ Based on unfounded assumption and dubious evidence,the arguer draws a conclusion that the construction of new generating plants will not be necessary.To substantiate his conclusion,the arguer points out the evidence that more energy efficient technologies are being used,thus the total demand of electricity will not increase in this area.The argument might seems to be valid and convincing at first glance,but the arguer’s reasoning is seriously flawed.
To begin with,the arguer points out that new technologies are able to reduce the energy needed for home heating,thus assumes without justification that the total demand for electricity will reduce.However,this depends on the underlying assumption that a lot of residents in this area will use utilities that use these kind of technologies.For example,if an air conditioner using this kind of technology cost much more than a normal one with use other source of power,many people won’t consider to buy it because of the price.So if this is true,then the arguer’s underlying assumption will be undermined. The arguer also depends on the gratuitous assumption that the energy needed for home heating equals to the total energy demand.But no evidence is stated in the argument to prove his assumption.It’s possible that the energy needed for home heating only account for a small proportion of total demand of energy.For example, more people drive cars using electricity as main power nowadays,this kind of use will consume a lot of electricity.Unless more evidence could be provided to prove the arguer’s assumptions,I can’t be convinced by the arguer.
Secondly,the arguer assumes too hastily that more energy efficient utilities will result in the decrease in energy use.The fact is that the use of energy efficient utilities is not sufficient evidence for the prediction that there will be a decrease in total energy demand.For instance,if every conditioner which use new technologies saves 30% of the energy than before,but twice more residents use air conditioners than before.There will still be an increase in total energy demand.
Moreover,the arguer assumes that the power plant could only be bulit because of the reason that supply can’t meet demand.However,this assumption is not quite true.Perhaps that the old power plants are not as energy efficient than the new one, so building a new one is good for the environment.Or perhaps that a new energy plant will be built to solve the emergencies that might happen in the future.Unless the arguer could rule out other possibilities that might render the construction of one ore more power plants necessary,the conclusion of the arguer can’t be accepted. |
