<em>The following were potential sources of power for the United States industries: coal fields, oil deposits, and rivers and streams.</em>
Industries need too much power in order to work efficiently 24/7. The United States industries used important sources of power to produce the number of goods that they needed to produce to have their products ready on a daily basis. Coal was much needed for some machines and for railroads. Trains used to work using coal. Oil deposits are abundant in some parts of the US territory and petroleum represented a new source of energy that made industries more efficient. And rivers and streams also create power. Indeed, many power plants are built next to rivers and in coastlines because they use water to generate power using powerful machines.
It was primarily "men" and "children" who formed the largest part of the factory labor force during the Industrial Revolution, since much of this took place before the government started regulating things like harsh labor conditions and child labor.
