From the study of fossil fuels and industries we know about coal and production of steel.
Electricity generation (Thermal power plant), Cement manufacturing industries and Iron & Steel industries benefited from their use.
Explanation:
Study of fossil fuels includes the details (process of formation, distribution, present storage capacity) of Coal, petroleum. In Carboniferous geological period coal was formed. It takes thousand of years to form coal by buring vegetation in under ground.
Petroleum found in sedimentary rock. 'Petra' means rock. It produces petrol, diesel, kerosene etc and by products vaselin. Thermal power plant, steel industries are established in the vicinity of coal producing areas. As it is a prime raw material of these industries. So to reduce the transportation cost it is an effective way to set industries near raw material producing region.
