Europe's Energy Crisis Isn't Over – Could Peak Oil Be the Next Shock?
Europe has already experienced several enormous energy shocks in just a few years.
First came the post-pandemic surge in energy demand and prices. Then Russia's invasion of Ukraine exposed Europe's dependence on Russian gas. More recently, conflict in the Middle East has demonstrated once again how vulnerable global oil and gas markets remain to events thousands of miles away.
The obvious question is what comes next.
Could the world be approaching peak oil – the point at which global oil production can no longer increase sufficiently to meet demand?
And if it does, will Europe face another energy crisis?
The answer may depend on how quickly the continent can replace fossil fuels with electricity from nuclear, wind and solar.
Peak oil does not necessarily mean running out of oil
This is an important distinction.
Peak oil does not mean that the world suddenly runs out of petroleum.
It means that demand or production reaches a maximum and subsequently begins to decline.
The International Energy Agency currently expects global oil demand to rise to around 105.5 million barrels a day by 2030 before broadly plateauing, with a small decline expected in 2030.
Electric vehicles are one of the major reasons.
The IEA estimates that electric cars could displace around 5.4 million barrels of oil demand per day by the end of this decade.
But not everybody agrees.
OPEC's latest outlook predicts that global oil demand will continue rising and reach around 124 million barrels a day by 2050.
That is an enormous difference between two highly influential organisations.
The future of energy is therefore far from settled.
Why Europe is particularly vulnerable
Europe's problem is that even when it reduces its dependence on one source of energy, it can remain exposed to the international market.
Russia supplied huge quantities of pipeline gas to Europe before the invasion of Ukraine.
Europe subsequently turned increasingly towards LNG and alternative suppliers.
That improved security against Russian supply disruption, but it also meant greater exposure to global LNG prices.
The European Commission says the continent's energy system has been transformed by the move from Russian pipeline gas towards global LNG markets, alongside rapid growth in renewables.
The result is a more diversified system, but also one in which energy prices can remain volatile.
This is the central lesson from the last few years:
energy security is not simply about where you buy your energy. It is also about how much energy you have to buy from somebody else.
Britain is already changing the equation
Britain provides some evidence that the transition can work.
During the first quarter of 2026, renewables provided 51.7% of electricity generation by major power producers.
Gas accounted for 35.1%, while nuclear supplied 12.4%.
Compared with a year earlier, renewable generation was up 23%, while gas generation fell 17%.
That is a remarkable change.
It means Britain is already generating more than half of its electricity from renewable sources during the period measured.
But there is a catch.
Electricity is only part of the energy system.
Britain still depends heavily on oil for transport and on gas for heating and industrial processes.
Replacing those uses is much harder than replacing gas-fired electricity generation.
Nuclear could be the missing piece
Wind and solar have one enormous advantage:
the fuel is free.
Once a wind turbine or solar panel is operating, nobody can suddenly increase the price of the wind or sunlight.
That is a major advantage over oil and gas.
But renewable generation is variable.
The wind does not always blow when electricity demand is high, and solar production falls dramatically during winter evenings.
That is where nuclear becomes important.
Nuclear power provides continuous low-carbon electricity and can operate regardless of the weather.
A combination of:
wind + solar + nuclear + storage + interconnectors + flexible demand
could therefore provide a much more resilient electricity system than relying heavily on imported fossil fuels.
Britain is already expanding interconnection with neighbouring countries, allowing electricity to be imported when cheaper elsewhere and exported when Britain has surplus renewable generation.
But Britain still needs gas
This is where the transition becomes complicated.
Gas remains important because it can respond relatively quickly when renewable generation is low.
The UK Government itself has acknowledged that gas currently plays an important role in maintaining electricity-system security while low-carbon alternatives are developed.
So even while Britain builds more wind and solar, it cannot simply switch off gas overnight.
That is why North Sea projects such as Rosebank and Jackdaw have become part of a much bigger argument about energy security.
The question is not whether Britain should eventually use much less oil and gas.
It is whether it should stop producing domestic supplies faster than it can replace them with reliable alternatives.
Oil is harder to replace than electricity
This is perhaps the biggest challenge.
Electricity can increasingly be generated from wind, solar and nuclear.
Cars can increasingly run on batteries.
But oil is also used for:
aviation;
shipping;
heavy transport;
plastics;
chemicals;
pharmaceuticals;
lubricants;
construction materials;
and thousands of industrial products.
That means even if road transport becomes largely electric, the world will still need substantial quantities of oil.
This is one reason the peak-oil debate is so difficult.
Oil demand can fall dramatically in one sector while remaining strong in another.
What happens if peak oil arrives before alternatives are ready?
This is the scenario Europe should be preparing for.
Imagine oil demand remains high but investment in new production falls because companies expect the oil age to be ending.
If supply then falls faster than demand, prices could rise sharply.
That would affect transport, manufacturing, food production and virtually every part of the economy.
It could also produce another inflation shock.
The irony would be that Europe could successfully reduce its dependence on Russian gas while becoming increasingly vulnerable to a different energy shortage.
But there is another possible future
The more optimistic scenario is that the transition happens faster than the decline in oil supply.
Electric vehicles continue replacing petrol and diesel cars.
Heat pumps and other technologies reduce gas consumption.
Wind and solar expand rapidly.
Nuclear provides dependable low-carbon electricity.
Batteries and other storage technologies improve.
Electric grids become stronger and better interconnected.
Hydrogen and other technologies begin replacing fossil fuels in industries where direct electrification is difficult.
In that world, peak oil becomes much less frightening.
Oil demand falls because consumers and businesses have alternatives.
The world doesn't need to find enough new oil because it needs less oil.
Scotland could have an unusual advantage
For Scotland, this transition could be particularly important.
The country has enormous renewable-energy resources, particularly offshore wind.
It also has decades of experience in offshore engineering.
That combination creates a potential bridge between the old energy economy and the new one.
The North Sea workforce that developed oil and gas could increasingly work on offshore wind, subsea electricity infrastructure, carbon capture, hydrogen and other technologies.
The challenge is ensuring that Scotland captures the manufacturing, engineering and supply-chain jobs rather than simply importing the equipment.
The real energy security strategy
Europe's experience over the last few years suggests that energy security cannot depend on one technology.
Nor can it depend on one country.
The answer is likely to be diversification.
More renewables.
More nuclear.
More storage.
More interconnection.
More domestic energy production.
Greater energy efficiency.
And, during the transition, enough gas and oil capacity to prevent shortages when alternatives cannot yet meet demand.
Britain's electricity statistics suggest that part of this transformation is already happening.
But transport, heating and industry remain much harder.
Peak oil could actually accelerate the transition
There is an interesting possibility that peak oil turns out not to be Europe's next great energy crisis but the event that finally accelerates the move away from fossil fuels.
If oil becomes increasingly expensive or unreliable, alternatives become more attractive.
Every electric vehicle means less exposure to petrol prices.
Every heat pump means less exposure to gas prices.
Every wind turbine reduces the amount of fuel Britain needs to buy.
Every nuclear reactor provides electricity without requiring imported fossil fuel.
And every improvement in energy efficiency reduces the amount of energy that has to be purchased in the first place.
That is a fundamentally different form of energy security.
But there is no quick fix
The danger is assuming that renewable energy can simply replace oil and gas overnight.
It cannot.
Building turbines, solar farms, nuclear stations, electricity networks, batteries and storage takes years.
The supply chains themselves require enormous quantities of steel, copper, concrete and other materials.
Planning and grid connections can take years.
And Britain will still need oil and gas during the transition.
The sensible strategy is therefore neither "keep using fossil fuels forever" nor "switch everything off immediately."
It is to make the transition quickly enough that the next energy crisis finds Europe less dependent on fossil fuels than the last one.
The next energy revolution is already under way
Europe has learnt an expensive lesson since 2022.
Energy security and climate policy are no longer separate issues.
They are the same economic problem.
The countries that generate more of their own electricity from wind, solar and nuclear will be less exposed to international fossil-fuel shocks.
The countries that remain heavily dependent on imported oil and gas will continue to be vulnerable to wars, sanctions, shipping disruptions and decisions made in distant capitals.
Peak oil could therefore be Europe's next crisis – or it could become the reason Europe finally breaks its dependence on fossil fuels.
The difference will depend on whether nuclear, wind, solar, storage and stronger electricity networks are built quickly enough to replace the fossil fuels as they decline.
The encouraging news is that the transition has already begun.
The worrying news is that the next energy shock could arrive before it is finished.
