Engineering Fundamentals: An Introduction to Engineering, 4th ed.c

while allowing for the standard of living to increase in the underdeveloped countries. To shed

light on the energy sources, generation, and consumption we will focus on U.S. data. However,

realize this is a global issue that requires global solutions by all engineers in the world. We are

merely using U.S. data here as a means to convey important information to you.

The U.S. primary energy consumption by source and sector is shown in Figure 13.13, and

its breakdown is shown in Figure 13.14. Next, we will briefly explain some of these major sources.
