When and why did the demand for petroleum explode?

The demand for petroleum exploded in the early 20th century, particularly after World War I, as industrialization and the rise of the automobile revolutionized transportation and manufacturing. The discovery of vast oil reserves, coupled with advancements in drilling technology, made petroleum more accessible and affordable. Additionally, the development of oil-based products, such as gasoline and plastics, further fueled its demand, leading to its establishment as a critical energy source in global economies.
