Oil, also known as petroleum, is a fossil fuel that accounts for 95% of consumption for transportation. It is a liquid fossil fuel formed from the remains of ancient marine organisms, primarily zooplankton and phytoplankton, which were buried under layers of sediment. Oil is the leading fossil fuel used worldwide for transportation needs, powering cars, trucks, ships, and airplanes. It is favoured for its high energy density and ease of transportation compared to other fuels. The transport sector accounts for about a quarter of global energy consumption and is a major source of emissions.

Petroleum products
Oil is the fossil fuel that accounts for 95% of consumption in the transportation industry. Oil can be refined to produce various petroleum products, which are widely used in transportation, such as gasoline, petrol, and diesel. Gasoline, which includes motor gasoline and aviation gasoline, is the dominant transportation fuel in the United States. It is used in cars, motorcycles, light trucks, boats, and various types of aircraft. Distillate fuels, primarily diesel fuel, are the second most widely used, accounting for 23% of total energy consumption by the transportation sector. They are commonly used in trucks, buses, trains, boats, and ships.
Trucks are typically used for shorter distances and have the advantage of providing direct travel from the source to the destination, such as delivering fuel to gas stations or directly to consumers. Barges and tankers are used for water transportation, with tankers being the only practical way to move crude oil across oceans. However, barges are more cost-effective for shorter distances and calmer waters due to their smaller size and lack of propulsion.
While pipelines are the most commonly used method for transporting petroleum, there are concerns about pollution and the risk of oil spills. Petroleum spills can be highly toxic to the environment and challenging to clean up. Regulations have been put in place to mitigate these risks and ensure safer transportation of petroleum products.

Biofuels
Oil is the fossil fuel that accounts for 95% of consumption for transportation. Oil is the leading fossil fuel used worldwide for transportation needs. It comes in the form of gasoline and diesel, which power cars, trucks, ships, and airplanes. The significance of oil in transportation is due to its energy density and ease of transportation compared to other fuels.
However, as the United States seeks to reduce greenhouse gas (GHG) emissions from motor vehicles and lessen its dependence on imported oil, biofuels are gaining traction as a possible solution. Biofuels are liquid fuels and blending components produced from biomass materials called feedstocks. They may also include methane from landfill gas and hydrogen from renewable sources. Most biofuels are used for transportation, but they can also be used for heating and electricity generation.
The U.S. Department of Energy Bioenergy Technologies Office (BETO) conducts research on transportation biofuels to accelerate the production of renewable-based fuels capable of reducing emissions in the aviation and maritime sectors. BETO advances sustainable aviation fuels through research and development in feedstocks, fuel conversion, and scale-up.
Biofuel production and consumption in the United States have generally increased each year since the early 1980s due to government policies and programs promoting or requiring biofuels instead of fossil fuels. In 2022, the United States produced about 18.7 billion gallons of biofuels and consumed about 17.6 billion gallons. Ethanol accounted for the largest share of U.S. biofuel production (82%) and consumption (75%) in 2022. Biodiesel, which is usually blended with petroleum diesel, was the second-largest share of U.S. biofuel production (9%) and consumption (9%) in 2022. Renewable diesel, chemically similar to petroleum diesel fuel, accounted for about 8% of production and 9% of consumption in 2022.

Natural gas
Compressed natural gas (CNG) is the most common fuel type for NGVs and is stored in a similar fashion to a car's gasoline tank. Some natural gas vehicles also use liquefied natural gas (LNG), which is created when natural gas is cooled to approximately −162 °C. LNG is a more flexible model that can save storage space and cost. Additionally, some natural gas vehicles are bi-fuel, meaning they can use either gasoline or natural gas.
Despite the advantages and increasing popularity of NGVs, they have not yet reached mass production due to several disadvantages.

Electricity
The transport sector accounts for a significant proportion of global energy consumption, with estimates ranging from 16% to 28% in the United States and around 25% worldwide. This energy consumption has significant implications for global economies, trade, and politics, as well as the environment.
Oil, a fossil fuel, accounts for 95% of energy consumption in the transportation sector. Oil is primarily used to power vehicles, including cars, trucks, ships, and airplanes. It is favoured for its energy density and ease of transportation compared to other fuels. Oil is refined into various petroleum products, including gasoline, petrol, and diesel oil, which are heavily used in the transportation industry.
The dominance of oil in the transportation sector has led to a reliance on fossil fuels, with global energy agencies reporting that oil represents the largest share of energy consumption. This has resulted in a significant environmental impact, as the use of fossil fuels releases massive amounts of carbon into the atmosphere in the form of CO2. To mitigate climate change, there is a growing emphasis on transitioning to renewable energy sources and electric vehicles.
To further reduce the environmental impact of the transportation sector, a range of solutions are being explored. These include the use of renewable fuels, such as green hydrogen, renewable diesel, and e-fuels, as well as the development of electric vehicles. Additionally, policy incentives such as subsidies for EV manufacturing and sales, and congestion charges in cities, are being implemented to encourage the adoption of cleaner technologies.

Fossil fuels
The transport sector accounts for a large proportion of global energy consumption, with estimates ranging from 16% to 28% in the United States and up to 25% worldwide. Fossil fuels, particularly oil, are heavily relied upon to meet this energy demand. Oil, also known as petroleum, is a liquid fossil fuel formed from ancient marine organisms and is the most-used energy source for transportation. It is favoured for its high energy density and ease of transportation compared to other fuels. Oil can be refined into various petroleum products, such as gasoline (or petrol), diesel, jet fuel, and heating oil, which are used to power cars, trucks, ships, airplanes, and sometimes, for heating buildings.
In 2023, petroleum products accounted for about 89% of the total US transportation sector's energy use. In the same year, biofuels contributed about 6%, most of which were blended with petroleum fuels. Natural gas, which is used to operate compressors for natural gas pipelines, accounted for about 5%. While natural gas is a significant component of the US energy mix for electricity generation, it is not as widely used for transportation.
The dominance of oil in the transportation sector has significant implications for global economies, trade, and politics. Oil price fluctuations often result from geopolitical events, highlighting the need to reduce dependency on fossil fuels and transition towards renewable alternatives. Electric vehicles and renewable fuels, such as green hydrogen, renewable diesel, and e-fuels, are already contributing to the replacement of fossil fuels in the transportation sector.
