Solution Manual For Roger A. Hinrichs, Energy: Its Use and the Environment, 6th Edition

PURPOSE AND PERSPECTIVE OF THE CHAPTER
The purpose of this chapter is to examine the fundamental concepts of energy. As discussed in
the chapter energy is a basic concept in all science and engineering disciplines. The concept of
energy conservation has also been explained in the chapter. Efforts of energy conservation
usually concentrate on either change to technology or lifestyle. Increased emphasis on energy
conservation is explained with the help of some convincing arguments.
Students should learn that the use of our energy resources is one of the major factors affecting
the environment. Using energy resources may 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 energy is
explained with the help of graphs. Recall from the beginning of this chapter that energy is not an
end in itself but is valued for what we can do with it. The end uses of energy are traditionally
broken down into four sectors: transportation, industrial, residential, and commercial.
Students should learn about energy resources, their limitations, and their uses. Students must
know how large each energy 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 energy
use means also understanding the consequences of its use. This chapter will introduce you to
the science of energy use and energy technology.
