At the beginning of the industrial revolution, wood was a major fuel source for home heating and steam engines, and water powered many of the industrial mills. These were replaced first by coal, then by oil. Train transportation and many industrial and home activities have been electrified. Gas and nuclear have been added as significant energy/power sources in the past 30-70 yrs.

There's much more to the story, but that part of your homework, I leave to YOU.
