Detailed explanation-4: -The Demand for Coal As the population increased, so did the domestic market, and people in town needed coal because they weren’t near to forests for wood or charcoal. More and more industries used coal as it became cheaper and thus more cost-effective than other fuels, from iron production to simply bakeries.
