Oil

Oil remains one of the world’s most important commodities. It fuels cars, lorries, ships and aircraft; it is used to make plastics, medicines, fertilisers, asphalt and countless everyday products; and its price can influence inflation, transport costs and household budgets. For readers in Worcester and across the UK, understanding how the oil market works helps explain why petrol prices change, why energy security matters and why the move towards cleaner transport is so significant.

This guide explains what oil is, how prices are set, why the UK still depends on it, and what consumers and local businesses can realistically do when fuel costs rise.

What is oil?

Oil, often called crude oil, is a naturally occurring liquid mixture of hydrocarbons found beneath the Earth’s surface. It formed over millions of years from the remains of tiny marine plants and animals that were buried, heated and compressed under layers of sediment.

Crude oil is rarely used in its raw form. It is transported to refineries, where it is separated into useful products through distillation and other processes. These products include petrol, diesel, kerosene-based jet fuel, heating oil, lubricants, waxes and feedstocks for petrochemicals.

That is why oil is more than a transport fuel. A single barrel can contribute to a wide range of goods and services, from packaging and electronics to road surfaces and medical equipment.

Main products made from oil

• Petrol: Used mainly in cars, motorcycles and smaller engines.
• Diesel: Used in lorries, buses, vans, trains, agricultural machinery and many industrial applications.
• Jet fuel: Used in aviation and produced from kerosene-range hydrocarbons.
• Heating oil: Used in some homes and commercial premises, particularly where mains gas is unavailable.
• Lubricants: Used in engines, machinery and industrial equipment.
• Petrochemicals: Used to make plastics, synthetic fibres, solvents, fertilisers and other materials.
• Asphalt: Used in road construction and maintenance.

A brief history of oil

People have used naturally occurring petroleum for thousands of years, but the modern oil industry began in the nineteenth century. In 1859, Edwin Drake drilled a successful commercial oil well in Titusville, Pennsylvania, helping to establish oil as a scalable industrial resource.

At first, kerosene for lamps was one of the most valuable products. The rise of the internal-combustion engine changed that. As cars, lorries, ships and aircraft spread during the twentieth century, petrol and diesel became central to global transport. Oil also became vital to war, manufacturing and international trade.

The twentieth century saw repeated attempts to manage production and prices. Major oil-producing countries formed OPEC in 1960 to coordinate petroleum policies, while consumer countries later created the International Energy Agency in response to the oil shocks of the 1970s. Those institutions still influence how governments and markets respond to disruption today.

Oil and UK energy security

Energy security means having reliable, affordable and sustainable supplies of energy. For the UK, oil is only one part of that picture, but it remains an important one because transport, industry and emergency services depend on fuel being available when needed.

The government maintains emergency oil stocks and participates in international arrangements designed to reduce the impact of supply disruptions. Refineries, storage terminals, pipelines and distribution networks all form part of the system that keeps fuel moving from global markets to local forecourts.

For consumers, energy security is not an abstract idea. It affects whether fuel is available during a crisis, how quickly prices recover after disruption and how resilient local supply chains are when international events cause delays. It also highlights why efficiency matters: using less fuel reduces both household exposure to price spikes and pressure on national supply systems.

How oil prices are set

Oil prices are driven primarily by global supply and demand. When demand rises or supply falls, prices tend to increase. When demand weakens or supply expands, prices often fall. In practice, however, prices can move quickly because traders respond not only to current conditions but also to expectations about future events.

The US Energy Information Administration identifies several major influences on crude oil markets, including supply from OPEC and non-OPEC countries, inventories, demand in OECD and non-OECD economies, financial markets and spot prices. Geopolitical events, severe weather, refinery outages and pipeline problems can also disrupt supply and increase volatility.

The role of OPEC

OPEC—the Organization of the Petroleum Exporting Countries—can influence prices by setting production targets for member countries. Its decisions matter because its members control a substantial share of the world’s oil reserves and production capacity.

OPEC does not fully control the market. Member compliance with quotas can vary, non-OPEC producers can increase output, and consumers may reduce usage when prices rise. But announcements about production cuts or increases can still move markets quickly because they change expectations about future supply.

Why prices can rise suddenly

Oil markets are sensitive to disruption. Conflict, political instability, attacks on shipping routes, hurricanes, cold weather and unexpected refinery closures can all reduce available supply or create uncertainty. Because demand for petrol and diesel does not fall much immediately when prices rise, even a relatively small disruption can have a noticeable effect.

In 2026, the International Energy Agency reported that conflict-related disruption, higher fuel prices and a weaker economic outlook were expected to reduce global oil demand by 2.6 million barrels per day compared with 2025. The agency also expected a partial recovery in 2027, although its forecasts remained subject to change as geopolitical and market conditions evolved.

Why oil matters in the UK

The UK produces oil in the North Sea, but it also imports crude oil and refined products. Domestic production has declined from its earlier peaks, while the country continues to rely on international markets for certain grades of crude and for fuels used across transport and industry.

Oil remains particularly important for transport. Cars, vans, lorries, buses, ships and aircraft still depend heavily on petroleum-based fuels. Although electric vehicles are growing in number, diesel remains central to freight, logistics, agriculture and public transport in many parts of the country. Even where alternatives exist, the transition takes time because it depends on vehicle availability, charging or refuelling infrastructure, upfront costs and the practical needs of businesses and households.

For Worcester, this has practical consequences. Local delivery firms, taxi and private-hire drivers, tradespeople, farmers, manufacturers and hospitality businesses all face higher costs when diesel and petrol prices rise. Those costs can pass through supply chains, affecting everything from food prices to event production.

What affects petrol prices at the pump

The price displayed at a UK petrol station is not simply the price of crude oil. It reflects several layers of cost and taxation.

This is why pump prices do not always move immediately in line with crude oil. Retailers may buy fuel in advance, wholesale prices can move separately from crude prices, and taxes form a significant part of the final cost.

Oil and the transition to cleaner energy

The UK has legally binding targets to reduce greenhouse-gas emissions, and oil is a major focus because burning fossil fuels releases carbon dioxide. The transition involves electric vehicles, public transport, renewable electricity, heat pumps, energy efficiency and lower-carbon fuels.

That does not mean oil will disappear quickly. Aviation, shipping, heavy freight, petrochemicals and some industrial processes are harder to decarbonise than everyday car travel. Oil is also still needed for many non-energy products, including plastics, lubricants and bitumen.

A realistic transition is therefore gradual. It involves reducing dependence where practical while maintaining reliable supplies for essential uses during the change.

What this means for drivers

• Electric vehicles can reduce exposure to petrol and diesel prices, although electricity costs, charging access and vehicle price remain important considerations.
• Efficient driving, correct tyre pressure and avoiding unnecessary weight can reduce fuel use in petrol and diesel vehicles.
• Combining trips, using public transport where available and walking or cycling for shorter journeys can lower both costs and emissions.
• Businesses with fleets can review route planning, driver training, vehicle choice and charging infrastructure.

How oil price changes affect Worcester

Oil price movements reach Worcester in several ways. The most visible is at the petrol station, but the effects extend further into the local economy.

Transport and deliveries

Higher diesel prices increase the cost of moving goods. Supermarkets, restaurants, bars, builders, retailers and event suppliers may face higher delivery bills. Some businesses absorb those costs temporarily; others pass them on through prices.

Hospitality and nightlife

Worcester’s pubs, clubs, restaurants and live-music venues depend on deliveries, staff travel and customer spending. When fuel costs rise, people may have less disposable income, while venues may face higher costs for food, drink, equipment and logistics.

At the same time, a vibrant local nightlife can reduce the need for long journeys. People who can enjoy good food, music and entertainment in the city centre may spend less on travel than if they need to drive elsewhere for a night out.

Household budgets

For households that depend on a car, fuel is often one of the most flexible short-term costs. People may combine errands, shop locally or reduce discretionary journeys when prices rise. That can affect footfall in city-centre businesses, particularly during periods of broader financial pressure. Venues and event organisers may respond by promoting local events, working with nearby suppliers and making it easier for people to enjoy a night out without a long or expensive journey.

How to reduce fuel costs

No one can control global oil markets, but drivers and businesses can take practical steps to reduce consumption.

• Compare local fuel prices: Prices can differ between nearby stations, so checking before filling up can save money over time.
• Drive smoothly: Gentle acceleration, anticipating traffic and avoiding harsh braking can improve fuel efficiency.
• Maintain your vehicle: Correct tyre pressure, regular servicing and removing unnecessary roof racks can reduce fuel use.
• Plan journeys: Combining errands and avoiding congestion saves both time and fuel.
• Consider alternatives: Public transport, walking, cycling and car-sharing can be cheaper for suitable journeys.
• Review business fleets: Route planning, driver training and vehicle replacement decisions can make a meaningful difference over several years.

Oil myths and misunderstandings

Myth: petrol prices rise immediately when crude oil rises

Crude oil is an important input, but pump prices also reflect refining, wholesale supply, distribution, taxation and local competition. Changes can take time to reach the forecourt.

Myth: the UK is fully independent from global oil markets

The UK produces oil, but it remains connected to international markets and imports certain crude oils and refined products. Global events can still affect UK prices and supply.

Myth: electric vehicles mean oil is no longer needed

Electric vehicles reduce petrol and diesel demand, but oil remains important for aviation, shipping, freight, industry and petrochemicals. The transition is broad rather than immediate.

Myth: oil prices only reflect supply and demand

Physical supply and demand matter, but financial markets, expectations, currency movements and geopolitical risk can also influence prices, sometimes before any physical shortage occurs.

FAQs
