What is energy? Where does the abundance of energy that people have available today come from? Since the industrial revolution began in the 18th century, humankind have discovered a multitude of energy sources to help power our society. The average life expectancy has been extended and the world’s population has grown, while our use of external energy sources continues to grow even faster. With that, there have been rewards, consequences and challenges along the way.
Refer to the information discussed in the previous Focus section as well as Part V of this text and elaborate on the following focus boxes, solving any problems that appear.
