# Combustion road vehicles: Relationships Source page: https://www.materialinsights.org/energy/e_road_ice/links/ Every element and industry that Combustion road vehicles is linked to, and how. Each pair has its own card explaining the relationships between the two. - [Crude oil](https://www.materialinsights.org/links/combustion-road-vehicles-and-crude-oil/): Road engines burn close to half of the world's oil, so the size and fuel efficiency of the combustion fleet is the largest single driver of crude demand. Electric vehicles displaced about 1.7 mb/d in 2025 and the IEA expects about 5 mb/d by 2030, while India adds more new oil demand to 2030 than any other country, led by transport fuels. *(researched)* - [Bioethanol](https://www.materialinsights.org/links/bioethanol-and-combustion-road-vehicles/): Almost all fuel ethanol is burned in petrol vehicles, so blending mandates such as India's E20 decide its market, while its lower energy content trims fuel economy by a few per cent. *(researched)* -
