题目：
The following appeared in a memorandum from the planning department of an electric power company.
"Several recent surveys indicate that home owners are increasingly eager to conserve energy. At the same time， manufacturers are now marketing many home appliances， such as refrigerators and air conditioners， that are almost twice as energy efficient as those sold a decade ago. Also， new technologies for better home insulation and passive solar heating are readily available to reduce the energy needed for home heating. Therefore， the total demand for electricity in our area will not increase—and may decline slightly. Since our three electric generating plants in operation for the past twenty years have always met our needs， construction of new generating plants will not be necessary."
Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.

一些最近的调查表明，房主越来越强烈地希望节省能源，并且生产商现在正在推出很多比十年前的电器几乎节能两倍的家用电器，比如冰箱和空调，这些电器要比10前出售的节能50%.而且，更好的房屋隔热和被动式太阳能采暖的新技术已经可以用于减少家庭采暖所需的能源。因此，我们预计我们地区的用电需求总量不会增加，而可能有轻微下降。由于我们的已经运作了20年的三座发电站总能够满足需求，我们无需建造新的发电厂。
写一篇回应，在其中检视文章的论证中述及和/或未明确述及的假设，务请解释文章的论证是如何依赖于这些假设的，并指出如果这些假设不成立会对文章的论证带来何种影响。
