Detailed Solution

The above statement is True.
In ancient times the energy needed was less as compared to nowadays. In ancient times, the majority of the requirements were done manually. Even the industrial work was done with human effort. Slowly, with the development of technology, men start to do the work with the help of machines. Primarily, small discoveries were there to reduce human effort, and now for everything, we use machines to get the work done faster.
Thus, reducing the human effort on one side; the other side was the exploitation of resources abundantly. It is quite obvious that energy is required to get the work done by machines. Hence, the various kinds of energy consumption increased, which, in fact, caused the growth of industries. In addition, the change in the lifestyle of humans and the increase in population led to an increase in energy consumption compared to ancient times.
