Explanation:

Crucial to industrialization was the replacement of human and animal power with inanimate sources of energy such as steam.

Over the centuries, humans and animals were largely used as a means to generate power, execute tasks or do certain things.

However, in the advent of industrialization and technological advancement, machines were invented to replace human and animal power.

Explanation:

The Industrial Revolution began in Britain during late 1700s and brought significant social changes. It spread to other technology driven countries like America. Before industrialization, local sources were used to generate power. These sources were easily depleted during use.

One of the driving factors of industrialization was how to exploit natural resources to make products. This resulted in an increase in population, for example immigration of people to urban areas.

The steam engine was crucial to Britain's industrial revolution which increased the demand for coal and the increase in coal production.
