Impact of the use of fossil fuels during the industrial revolution was it made possible a huge increase in the amount of productive energy available to humans.
The development of machines, including steam engines and the internal combustion engine, made it possible to exploit vast new resources of energy stored in fossil fuels, specifically coal and oil. The fossil fuels revolution greatly increased the energy available to human societies during industrial revolution.
