Petroleum has had the most significant influence on human transportation over the last century. It has been the primary fuel for vehicles, including cars, trucks, airplanes, and ships, dominating the transportation sector due to its energy density, convenience, and established infrastructure. While coal and natural gas have been used in various transport applications, and hydrogen is increasingly being considered as an alternative, petroleum remains the cornerstone of modern transportation systems.
