Life Without Oil: The Unthinkable Scenario

For nearly two centuries, mineral oil has been the unseen, yet profoundly powerful, engine of human progress and prosperity. Since its large-scale exploitation began in the 1850s, this energy-intensive and remarkably versatile liquid has woven itself into the very fabric of modern society. Today, as global conversations increasingly shift towards sustainability and climate action, the radical notion of completely ceasing oil production is gaining traction. But what if this hypothetical future arrived not as a gradual transition, but as an abrupt, unforeseen disappearance? The implications, as experts warn, would be nothing short of catastrophic.

While some envision an idyllic, post-oil utopia, others foresee a doomsday scenario. The reality, as painted by economists and transport specialists, lies closer to the latter. Our entire global infrastructure, economic systems, and daily conveniences rest precariously on the availability of oil. We've become so accustomed to its presence that its foundational role often goes entirely unrecognised, making the prospect of its sudden absence almost unfathomable.

The Invisible Engine of Modernity

Our modern existence, with its intricate supply chains, instant communication, and global mobility, is fundamentally underpinned by energy, much of which derives from hydrocarbons. Eirik Wærness, chief economist at Equinor, starkly outlines this dependency: “Our entire prosperity, economic progress and economic system, and the whole communication system which allows us to visit each other in a completely different way than we did before, for example, are based on an economy with access to very efficient energy sources.” He notes that coal, oil, and gas are simultaneously in use, but if oil vanished tomorrow, it would be a society utterly transformed from its 1850 predecessor.

To put oil's energy density into perspective, one barrel of crude oil, approximately 159 litres, packs a punch equivalent to 1,300 kilowatt-hours. That's enough energy to power a typical Norwegian detached house for an entire month. A single litre of petrol contains roughly 9.1 kWh, sufficient to heat 80 litres of water from room temperature to boiling point. This immense energy concentration is precisely why oil became, and remains, so indispensable.

A World Grounded to a Halt: The Transport Catastrophe

Perhaps the most immediate and visible impact of oil's disappearance would be on transport. Kjell Werner Johansen, deputy head of the Norwegian Institute of Transport Economics (TØI), underscores this global implication. The sector, he explains, is crucial for trading goods and services, yet no distribution network currently exists that isn't reliant on the internal combustion engine. Without oil, aviation, shipping, and road haulage would simply cease.

Consider the ripple effect: global trade would face insurmountable difficulties. While electric trains exist, rail freight still depends on lorries and vans at either end of the track for last-mile delivery. Even in countries like Norway, a world leader in electric car adoption, less than seven per cent of passenger cars are electrically powered. More critically, over 99 per cent of utility vehicles—the lorries and buses that move goods and people—run on diesel or petrol. As service stations ran dry, these vital arteries of society would seize up.

Furthermore, the notion of simply manufacturing more electric vehicles is flawed. Electric cars themselves contain numerous oil-based products, from tyres to interior plastics, and their components are sourced globally, transported using fossil fuels. The global car industry lacks the immediate capacity to convert solely to electric vehicle production, let alone transport the necessary materials without petroleum.

Feeding a Silent World: Food Production Without Oil

The abrupt absence of oil would also plunge food production into a profound crisis. Johansen highlights that the raw material position would become critical. Farm tractors and other essential agricultural equipment would halt. Fishing boats, powered by diesel engines, would be unable to put out to sea, severely impacting food supplies from the oceans.

Even more alarming is the dependency of artificial fertiliser production on natural gas, which reacts with nitrogen to create essential nutrients for crops. While alternatives to natural gas for this purpose might exist, they could not be implemented overnight. Without fertilisers, agricultural yields would plummet, leading to widespread food shortages and potential famine. Adapting to a world without industrial agriculture would necessitate a return to smaller-scale, localised, and seasonal food production, a transformation estimated to take at least 10-20 years for basic everyday life to be maintained.

Beyond Fuel: The Plastic Predicament

Oil is not just about fuel; it's the fundamental building block for countless products that define our daily lives. Plastics, one of the most important substances derived from oil, would become impossible to produce on anything resembling today’s scale if petroleum output suddenly stopped. The petrochemical industry alone consumes about four per cent of global oil and gas output.

It's almost easier to list what doesn't contain plastics. Polyethylene (PE), derived from oil, is used in packaging, building films, carrier bags, pipes, bottles, electrical insulation, household items, toys, and even advanced biomaterials for artificial human joints and high-strength fibres. Furniture, building materials, paints, computers, mobile phones, and cars all rely heavily on oil-based plastics. Sports equipment, clothing, carpets, and textiles—including nylon ropes—are all deeply reliant on petroleum derivatives. Look around any room, and you'll find plastics in almost everything. This material has been a cornerstone of countless innovations, making cars and aircraft lighter and more fuel-efficient.

While biomass can theoretically produce many of these substances – for example, “everything which can be made with oil can be produced from trees” – the scale and speed required for conversion are monumental. Norway's forests could provide more timber, but scaling up production of bioethanol or raw materials for cement, paint, and cosmetics would take an extremely long time and, ironically, still require diesel to transport the timber. Moreover, many plastics derived from wood are no more degradable than those from oil, with only a tiny fraction degrading quickly in nature.

A Cold, Dark Reality: Heating and Energy Shortfalls

The disappearance of oil would also severely impact Europe's energy landscape. While gas is often discussed in relation to power generation, a significant portion—40 per cent of Norway's gas exports to Europe—is used directly for cooking and domestic space heating, particularly in the UK. Hildegunn Blindheim, director for climate and the environment at the Norwegian Oil and Gas Association, warns that a sudden halt to petroleum production would leave most Europeans unable to cook or heat their homes.

The remaining gas exports are crucial for industrial purposes, achieving extreme production temperatures or direct conversion to fertiliser. In the case of oil, 10-15 per cent of Norwegian production is used for manufacturing various products, a share expected to double by 2050. A sudden loss of oil supplies would make it impossible to meet global energy needs. Existing natural gas stocks would be depleted in weeks, leading to intense competition for what remains. Coal could see a resurgence, but this is hardly a sustainable solution.

The Fragile Promise of Alternatives

Renewable energy sources are growing faster than ever, but they are far from ready to fill the immense void left by oil and gas. In 2018, renewables covered the rise in energy consumption for the first time, yet 80 per cent of global demand is still met by fossil fuels. If oil vanished, renewables would need to cover this four-fifths share plus any further growth—an impossible feat in the short term, regardless of falling costs for solar cells and wind power.

Biofuel production, while an option, is currently very limited. Norway's Borregaard produces 20 million litres of bioethanol annually, entirely used for blending with conventional petrol. This quantity is minuscule compared to the demand for petrol and diesel. A rapid conversion to large-scale biofuel production is fraught with difficulties, not least the need for fossil fuels to harvest and transport the raw biomass like algae, seaweed, or timber.

The Only Way Out: A Managed Transition

The consensus among experts is clear: a sudden, uncontrolled cessation of oil production would be catastrophic. The only sensible path is a planned and controlled transition from fossil fuel dependency to a more sustainable existence. This involves a gradual reduction of emissions from industry and power generation, using a multi-faceted approach.

One key solution is Carbon Capture and Storage (CCS), where CO2 emissions are captured and stored, often beneath the seabed. Norway, with its extensive oil industry experience, is well-positioned to lead in this area, with trials and full-scale plant developments underway. Another promising avenue is hydrogen, produced from natural gas or via electrolysis, as a clean energy carrier. The oil industry itself plays a crucial role in developing these technologies, leveraging its expertise in large-scale energy projects.

The transition cannot be rushed without immense societal cost. Energy consumption fluctuates greatly, and while renewables offer immense potential, their intermittency (dependence on sun and wind) presents a significant challenge. Building infrastructure to ensure constant renewable power requires colossal investment and time. Natural gas, or hydrogen derived from it, could serve as a 'massive battery' to smooth out these fluctuations, providing power when renewables are unavailable.

Navigating the Future: Expert Perspectives and Challenges

Few believe demand for petroleum will drastically fall in the near future. Therefore, efforts to cut emissions from hard-to-decarbonise sectors like air, sea, and heavy road transport are crucial. Experts like Hildegunn Blindheim advocate for using "the whole toolbox of measures" to reach climate goals, with oil industry expertise contributing to solutions like carbon storage and hydrogen production for shipping.

Eirik Wærness stresses the need for continued economic growth while securing energy-efficient hydrocarbon delivery with minimal emissions during production. This includes more effective internal combustion engines, rapid electrification in transport (electric cars, buses, local delivery lorries), and increased use of biofuels and natural/bio gas. While oil demand will decline, gas consumption may persist longer, eventually also declining.

Johan Einar Hustad, director of NTNU Energy, emphasises the importance of international collaboration and changing consumption patterns. Consumers need choices and incentives to adopt renewables. He warns that shutting down the oil sector abruptly would be destructive, leading to a regression to a pre-oil age or even further back. While acknowledging the urgency of climate action, he stresses that moving too fast could destroy opportunities for creating sustainable replacements. The call from young people for immediate cessation is vital for shifting policy, but the practicalities demand a measured, strategic approach.

Frequently Asked Questions (FAQs)

What would be the immediate impact on daily life if oil disappeared?

The immediate impacts would be widespread paralysis. Transport systems (cars, lorries, planes, ships) would halt, leading to empty shop shelves, disruptions to emergency services, and people unable to get to work. Heating and cooking in many European homes would cease, and access to essential goods, including medicines, would be severely compromised.

How would food production be affected without oil?

Food production would face a critical raw material position. Farm machinery would stop, fishing boats couldn't operate, and the production of artificial fertilisers, crucial for modern agriculture, would be severely hampered due to its reliance on natural gas. This would lead to drastic reductions in crop yields and widespread food shortages.

Are electric vehicles and renewables enough to replace oil quickly?

No. While electric vehicles are growing in popularity, they represent a small fraction of the global fleet, especially utility vehicles. Furthermore, the manufacturing and transport of electric vehicle components still rely on fossil fuels. Renewables are expanding rapidly, but they currently meet only a fraction of global energy demand and face challenges with intermittency and storage capacity, making them insufficient for an immediate, large-scale replacement of oil's diverse uses.

How long would it take to adapt to a world without oil?

Experts estimate that converting to a basic everyday life without oil, involving a return to more localised and smaller-scale agriculture, would take at least 10-20 years. However, this assumes a gradual, managed transition, not a sudden disappearance, which would be far more disruptive and challenging.

What role can the oil industry play in a sustainable future?

The oil and gas industry possesses significant expertise and infrastructure that can be leveraged for sustainable solutions. This includes developing and implementing Carbon Capture and Storage (CCS) technologies, producing hydrogen as a clean energy carrier, and innovating to reduce emissions from existing hydrocarbon production and use. Their experience in large-scale energy projects is crucial for the energy transition.

In conclusion, the thought of a world without oil, while appealing to some in its simplicity, masks a profound and terrifying reality. Our societies are built upon its ubiquitous presence, enabling global trade, feeding populations, powering homes, and providing the materials for almost every product we touch. A sudden disappearance would not lead to a swift shift to renewables, but rather a reversion to a pre-industrial age, marked by economic collapse, widespread famine, and societal breakdown. The path forward, as experts agree, is not an abrupt cessation but a carefully managed, long-term transition, leveraging technological innovation and international collaboration to gradually decarbonise our energy systems while maintaining the prosperity oil has afforded us.
