The fuel economy of an automobile relates to the distance traveled and the amount of fuel consumed. Fuel consumption and fuel economy are sometimes used interchangeably but differ in that the former measures how much fuel a car consumes to travel a certain distance, while the latter measures how much distance a car can cover with a given volume of fuel. The fuel economy of a vehicle is influenced by its design, usage patterns, and driver behavior. It is also a significant factor in a nation's foreign trade and air pollution, with many countries imposing requirements for fuel economy. The oil and natural gas industry, for instance, supports a substantial portion of the US economy, contributing to nearly 8% of the nation's Gross Domestic Product and providing over 10 million jobs.

Oil & Natural Gas: supports 10.3 million jobs in the US, 8% of GDP
Oil and natural gas are key components of the US economy, with the sector employing 10.3 million people across the country, according to the American Petroleum Institute. This number rose to 10.8 million in 2021, according to data from the same year. This makes up 5.4% of the country's workforce. The industry also contributes nearly $1.8 trillion per year to the US economy.
The oil and gas sector is one of the world's most important industries, with high demand for labour. In 2019, the global energy sector employed more than 41 million people. This includes 6.3 million in the oil supply segment and 3.9 million in gas supply.
The industry includes exploration, development, and operation of oil and gas fields, as well as crude petroleum production, and the mining and extraction of oil from shale or sands. Some of the biggest players in the industry include Exxon, Chevron, and BP.
The American Petroleum Institute states that the industry makes up roughly 8% of US GDP. However, another source suggests that the industry accounts for 4.8% of the nation's GDP. This discrepancy could be due to differences in the scope of what is included in the industry or the methodology used to calculate the GDP contribution.
The oil and gas industry is a key driver of the global economy and is expected to continue growing. The 2023 outlook for oil demand has already risen, and the estimate for 2024 is 102.8 million barrels per day.

Fuel efficiency: vehicle design and usage patterns impact fuel economy
Fuel efficiency is a critical aspect of modern economies, with liquid fuels like gasoline, diesel, and jet fuel dominating the energy consumption landscape. The transportation sector, including road vehicles, plays a significant role in this dynamic. Vehicle design and usage patterns have a substantial impact on fuel economy, offering opportunities for optimization and reduced environmental impact.
Vehicle design is a key factor in fuel efficiency. Engineers employ advanced mathematical tools to simulate vehicular performance and fuel economy dynamics, allowing them to make informed decisions about design configurations and powertrain alternatives. A critical aspect of vehicle design is reducing the vehicle's mass, which leads to lower traction power requirements and reduced wheel rolling resistance during acceleration, resulting in fuel savings. Additionally, advancements in tire technology, such as improvements in material composition and tire labeling systems, help reduce rolling resistance, further contributing to fuel efficiency.
The selection of feedstock and fuel production pathways also impact the overall energy efficiency of road vehicles. For example, battery electric vehicles (BEVs) have higher in-use energy efficiency compared to hybrid electric vehicles (HEVs). BEVs can convert 70-90% of the energy stored in the battery into movement, while HEVs have a theoretical peak efficiency of only 40%. However, conversion losses during electricity generation and transmission, as well as the energy consumption of auxiliary systems in BEVs, can offset some of these advantages.
Usage patterns also play a significant role in fuel economy. Driver behavior, such as acceleration patterns, speed, and gear-shifting practices, can greatly impact fuel consumption. Distractions, such as mobile phone use at traffic lights, lead to delayed responses and increased idling, contributing to higher fuel consumption and emissions. Traffic flow, road conditions, and traffic signals influence driving patterns and fuel efficiency in urban environments. By optimizing speed and load regimes, transportation systems can achieve maximum efficiency and reduced fuel consumption.
In summary, advancements in vehicle design and a better understanding of usage patterns offer significant opportunities to improve fuel economy and reduce environmental impact. Optimizing vehicle mass, tire technology, feedstock selection, and driver behavior can collectively contribute to enhanced fuel efficiency and a more sustainable transportation sector. These efforts not only reduce a country's economic vulnerability by decreasing reliance on energy imports but also contribute to the broader goal of environmental sustainability.

Driver behaviour: aggressive driving wastes fuel, sudden acceleration, heavy braking
Fuel is a significant component of the economy, and aggressive driving behaviours such as speeding, rapid acceleration, and hard braking can have a substantial impact on fuel efficiency and costs. Speeding is one of the most costly and deadliest forms of aggressive driving, with a 50% increase in speed more than doubling the energy released in a crash. According to the Department of Energy, aggressive driving can lower fuel mileage by 15-30% at highway speeds and 10-40% in stop-and-go traffic. For example, a truck travelling at 75 mph uses 27% more fuel than at 65 mph. This not only increases fuel costs but also contributes to a negative public image of the trucking industry.
Additionally, rapid acceleration and late, hard braking also increase fuel consumption. Driver feedback devices can assist in improving fuel economy, with studies suggesting they can help the average driver improve fuel efficiency by about 3%. Maintaining a constant speed, such as through the use of cruise control, can also help save fuel. Other fuel-saving tips include turning off the engine when the vehicle is parked and removing external cargo containers when not in use, as they can reduce fuel economy by up to 25% at interstate speeds.
The economics of the trucking profession, such as tight schedules and piece-rate compensation, can incentivize aggressive driving behaviours. However, carriers can play a role in validating the argument by comparing the safety and citation records of their most and least fuel-efficient drivers. Training and counselling can also help improve drivers' emotional performance and educate them about aggressive driving habits.
By adopting more sensible driving behaviours, drivers can not only save on fuel costs but also contribute to safer roads and a more positive industry image.

Fuel consumption: litres per 100km, lower values indicate better fuel economy
Fuel consumption and fuel economy are important factors in the global economy, with fuel consumption by vehicles being a significant contributor to air pollution.
Fuel economy is the distance travelled per unit volume of fuel used. This can be expressed in various ways, including litres per 100 kilometres (L/100 km), kilometres per litre (km/L), or miles per gallon (MPG). The specific measure used depends on the region. L/100 km is the standard measure in Europe (except the UK, Denmark, and the Netherlands), Africa, New Zealand, Australia, Canada, and several other countries. In the US and the UK, MPG is commonly used, while in Europe, India, Japan, and South Korea, km/L is the metric unit.
L/100 km indicates how many litres of fuel a vehicle consumes per 100 kilometres travelled. Lower values in L/100 km indicate better fuel economy, meaning the vehicle is more efficient and consumes less fuel to travel the same distance. For example, a vehicle with a fuel efficiency rating of 5.7 L/100 km is more fuel-efficient than one rated at 9.1 L/100 km.
The fuel economy of a vehicle can vary based on several factors, including the type of fuel and engine. For instance, diesel engines tend to be more fuel-efficient than petrol engines due to their higher compression ratio and the higher energy content of diesel fuel. Additionally, driving conditions can impact fuel economy, with highway driving typically being more efficient than city driving due to reduced stop-and-go cycles.
While fuel economy measures like L/100 km provide valuable information about a vehicle's efficiency, other factors also influence fuel consumption and costs. For example, the total distance travelled and the price of fuel must be considered to accurately estimate fuel expenses. Additionally, alternative fuel options, such as LPG, may offer cost savings despite lower fuel economy due to their lower price per litre.

Foreign trade: fuel imports are a large part of international trade for many nations
Fuel imports are a critical component of international trade for numerous nations. The import and export of petroleum and crude oil play a significant role in the global economy. For instance, the United States, despite becoming a net exporter of petroleum in 2020 for the first time since 1949, still relies on crude oil imports from various countries to meet domestic demand. In 2022, the US imported approximately 6.28 million barrels of crude oil per day, with Canada being the largest single source of these imports, accounting for 52% of total petroleum imports and 60% of crude oil imports.
The sources of fuel imports can vary, with OPEC countries traditionally being significant suppliers. However, their share of imports has generally declined since 1977. Saudi Arabia, for instance, was responsible for 7% of US total petroleum and crude oil imports in 2022, making it the largest OPEC petroleum exporter to the US. Persian Gulf countries collectively contributed about 12% of US petroleum and crude oil imports during the same year.
The dynamics of fuel imports can be intricate, as companies that import crude oil may not use those imports directly to produce the gasoline sold under their brand. Gasoline from various refineries and import terminals is often blended during pipeline transportation. This means that service stations in the same area may be selling gasoline sourced from the same terminal, which could include imported gasoline or gasoline refined from imported oil.
Fuel imports are essential for countries that rely on them to meet their energy demands. While some nations, like the US, may occasionally become net exporters, they still require imports to supplement their domestic production. This highlights the complex nature of the global fuel trade and the interconnectedness of countries in this vital aspect of the international economy.
