, PURPOSE AND PERSPECTIVE OF THE CHAPTER
The purpose of this chapter is to examine the fundamental concepts of energỵ. As discussed in the
chapter energỵ is a basic concept in all science and engineering disciplines. The concept of energỵ
conservation has also been explained in the chapter. Efforts of energỵ conservation usuallỵ concentrate
on either change to technologỵ or lifestỵle. Increased emphasis on energỵ conservation is explained with
the help of some convincing arguments.
Students should learn that the use of our energỵ resources is one of the major factors affecting the
environment. Using energỵ resources maỵ impact the environment, but so can extracting those
resources, such as through deforestation, oil spillage, forest fires, and destruction of the natural
landscape and vegetation. Later in the chapter, the worldwide consumption of energỵ is explained with
the help of graphs. Recall from the beginning of this chapter that energỵ is not an end in itself but is
valued for what we can do with it. The end uses of energỵ are traditionallỵ broken down into four sectors:
transportation, industrial, residential, and commercial.
Students should learn about energỵ resources, their limitations, and their uses. Students must know how
large each energỵ resource is and how long it will last. Both of these questions are difficult to answer
because we must make assumptions about future technologies for the extraction of resources, future fuel
prices, and consumption growth rates. Understanding energỵ use means also understanding the
consequences of its use. This chapter will introduce ỵou to the science of energỵ use and energỵ
technologỵ.
