Final answer:
Petroleum's versatility is a key reason it continues to be a dominant energy source, with substantial use in transportation and industry.
Step-by-step explanation:
The statement that petroleum's versatility ensures that petroleum-related products still dominate energy usage is true. Petroleum is indeed a highly versatile energy source, used widely across various sectors, particularly for transportation fuels like gasoline, diesel, and aviation fuel. In the U.S., 37% of the energy consumption comes from petroleum, with a significant 70% used in transportation. Globally, petroleum accounts for around 31% of total energy consumption. Apart from its use in transportation, it is also heavily used in industrial processes and for the production of plastics and other important materials. As such, it firmly holds its place as a dominant energy source due to its vast applicability and the existing infrastructure that supports its use.
