Here are the top five uses for oil globally, along with their approximate percentage shares of total oil consumption:

Key Notes:

• Transportation fuels (gasoline, diesel, jet fuel) dominate oil use, powering cars, trucks, ships, and planes.
• Petrochemicals are used to make plastics, fertilizers, and synthetic materials.
• Heating and electricity are more significant in regions with oil-fired power plants or heating systems.
• Industrial use includes manufacturing and machinery.
• Percentages can vary by country and year, especially with shifts toward renewables and electric vehicles.

Key Points:

• Transportation (road, air, marine) remains the largest sector, accounting for about half to two-thirds of global oil demand, with road transport alone responsible for around 50% in OECD countriesstatista.com+1.
• Petrochemicals (plastics, fertilizers, synthetic materials) are the second-largest and fastest-growing sector, driven by demand for feedstocksiea.org.
• Heating and electricity use is declining in some regions due to electrification and renewable energy adoption, but still significant in othersiea.org.
• Aviation and industrial use (including manufacturing and machinery) round out the top fiveiea.org+1.
