The Strait and the System

What $100 oil reveals about the fragility of the fossil economy, and why the age of electricity is arriving faster than we think.

Oil crossed $100 a barrel yesterday.

One geopolitical shock. One shipping lane. One narrow strait.

That’s all it took to move the global economy.

But at the same moment a new analysis from Ember revealed something markets are only beginning to understand.

Oil shocks remind us how fragile the fossil system is. Ember’s analysis reminds us how small it already is.

For decades we have described the global energy system using a single number.

Roughly 80% of the world’s energy still comes from fossil fuels.

That statistic appears in policy speeches, investor decks, academic papers, and newspaper columns. It has become the shorthand for energy realism. Fossil fuels dominate. The transition will be slow.

But that statistic depends on how we choose to count energy.

And the way we count it is deeply misleading.

The Energy Accounting Mistake

Most energy statistics begin with primary energy supply.

Barrels of oil extracted from the ground. Tons of coal mined. Cubic meters of natural gas produced.

Add them together and you get the familiar picture: a global system still overwhelmingly powered by hydrocarbons.

But Ember’s recent analysis reframes the system from the perspective that actually matters. From the perspective of the consumer.

After all, people do not demand barrels of oil or tons of coal.

They demand outcomes.

Motion. Heat. Light. Industrial work.

Energy is simply the means to deliver those services.

When we shift the accounting from fuel supplied to useful energy delivered, the picture changes dramatically.

Because a staggering share of the energy entering today’s fossil system never actually performs useful work.

It becomes waste heat.

In fact, according to the Ember analysis, roughly two-thirds of the energy entering the global system is lost before it ever reaches the consumer as useful energy.

Gasoline engines lose most of their energy as heat.

Coal-fired power plants waste the majority of their fuel before electricity reaches the grid.

Industrial combustion systems burn enormous quantities of energy simply to overcome thermodynamic limits.

The fossil system is not just carbon intensive.

It is thermodynamically inefficient.

And that inefficiency distorts the way we think about the scale of the transition.

Fuel Burned vs. Work Delivered

Once you start looking at the energy system through this lens, a simple distinction appears.

The global system is not really organized around fuels.

It is organized around two different ways of delivering energy.

Molecules and electrons.

Molecules - oil, gas, coal, biomass - store energy in chemical bonds. To release that energy they must be burned, producing heat that must then be converted into motion, electricity, or industrial work.

Each step in that process loses energy.

Electrons work differently.

Electricity arrives already organized as moving charge. Electric motors convert electricity into motion with extraordinary efficiency. Heat pumps deliver thermal energy at multiples of the electrical energy they consume.

Electric systems do not escape the laws of physics.

But they waste far less energy obeying them.

Which means the comparison between fossil fuels and electric technologies is not just about emissions.

It is about thermodynamics.

A system built on combustion will always lose large quantities of energy before delivering useful work.

A system built on electricity avoids many of those losses entirely.

And that difference matters not just for climate.

It matters for economics, security, and global stability.

Why Oil Shocks Still Matter

And yet, despite all of this, oil still moves markets.

Yesterday’s price spike was triggered by the reality of the conflict in the Middle East. It has disrupted traffic through the Strait of Hormuz, a narrow corridor through which roughly a fifth of global oil supply flows.

The world has seen this movie before.

A regional conflict threatens a shipping lane.

Energy prices surge.

Inflation fears follow.

Central banks take notice.

It is a vivid reminder that the fossil energy system was built around molecules that must move.

Extracted in one place. Shipped across oceans. Refined in another. Burned somewhere else.

Every step introduces risk.

Geopolitical risk. Logistical risk. Price volatility.

The system works.

But it is fragile.

The modern world still runs on fuels that must pass through chokepoints.

Straits. Pipelines. Shipping lanes.

And every chokepoint introduces leverage.

Whoever controls the chokepoint can influence the economy that depends on it.

That reality has shaped geopolitics for more than a century.

Wars have been fought over it. Alliances built around it. Navies deployed to protect it.

The fossil energy system did not just shape the global economy.

It shaped the global security architecture.

The Rubin Warning

In 2008, Canadian economist Jeff Rubin wrote a book arguing that $100 oil could fundamentally reshape the global economy.

His thesis was simple: when energy becomes expensive enough, globalization begins to fracture.

Manufacturing moves closer to consumption.

Supply chains shorten.

Energy-intensive trade declines.

At the time, the argument sounded dramatic.

But Rubin was identifying a deeper truth.

Energy prices shape the structure of the global economy.

What he could not have fully anticipated was that the more profound shift would not simply be the price of oil.

It would be the replacement of molecules with electrons.

Because once energy systems become electrified, geography changes.

Sunlight does not pass through maritime chokepoints.

Wind does not depend on shipping lanes.

Electrons move through wires.

And when energy becomes infrastructure instead of fuel, the strategic map changes.

The Security Dividend

This is one of the most under-appreciated dimensions of the energy transition.

Electrification does not simply reduce emissions.

It reduces geopolitical exposure.

Energy systems built around domestic electricity generation are fundamentally harder to weaponize.

You cannot embargo sunlight.

You cannot blockade the wind.

And electrons do not pass through maritime chokepoints.

That matters enormously for global security.

For the first time in modern history, the technologies capable of decarbonizing the economy are also the technologies capable of decentralizing energy power.

Solar panels can be installed almost anywhere.

Wind turbines generate power where the wind blows.

Electric infrastructure turns energy into a network rather than a commodity.

This does not eliminate geopolitical risk.

But it reduces the number of single points of failure capable of destabilizing entire economies.

The implications extend far beyond climate.

A world less dependent on globally traded fossil fuels is a world with fewer energy chokepoints, fewer resource conflicts, and fewer incentives for geopolitical brinkmanship.

Energy transitions do not guarantee peace.

But systems that reduce scarcity and volatility make stability easier to sustain.

Which means the transition toward electrification is not just an environmental project.

It is a security strategy.

And potentially one of the most powerful economic development stories of the century.

Because energy that is cheaper, more efficient, and locally produced supports prosperity.

Communities retain more value.

Countries reduce exposure to external shocks.

And industries gain access to energy that becomes steadily cheaper over time.

The result is a system that is not just cleaner.

But more stable.

Stocks vs. Flows

There is another insight in the Ember analysis that investors will immediately recognize.

Most discussions about energy focus on stocks.

How large the fossil system currently is.

How many pipelines exist.

How many barrels of oil are consumed each day.

Stocks describe the past.

But markets move based on flows.

Where growth is occurring.

And when we examine the flows in the energy system, the picture changes again.

Solar, wind, and hydro already account for a large share of electricity generation.

But more importantly, they account for the overwhelming majority of new electricity capacity being added globally.  As geothermal power begins to join the electron orchestra, the growth compounds.

In other words, the incumbent system dominates the stock.

The emerging system dominates the flow.

And flows determine the future.

Why the “80% Fossil” Statistic Will Age Quickly

This is where the Ember analysis becomes particularly important.

Because once energy is measured from the perspective of useful work, electrification begins to compress the scale of the energy system itself.

Electric motors deliver motion far more efficiently than combustion engines.

Heat pumps produce several units of heat for each unit of electricity consumed.

Digital systems replace energy-intensive mechanical processes.

The result is something counterintuitive.

As the energy system electrifies, less total energy is required to deliver the same economic output.

Which means the apparent dominance of fossil fuels, measured through primary energy supply, will shrink faster than many analysts expect.

The denominator changes.

The system becomes more efficient.

And the statistics that once described the fossil era begin to lose their power.

The Investor Signal

Which brings us back to oil crossing $100.

Oil crossing $100 feels like a reminder of fossil dominance.

But the deeper signal may be the opposite.

Every price spike reminds governments how exposed their economies are to distant conflict.

Every price spike reminds investors how volatile molecule-based energy systems can be.

And every price spike quietly strengthens the case for something different.

Energy systems built on electrons instead of molecules. Domestic infrastructure instead of imported fuels. Thermodynamic efficiency instead of combustion losses.

This is why the capital flows are shifting.

Not out of ideology.

Out of arithmetic.

Oil shocks remind us how fragile the fossil system is.

Ember’s analysis reminds us why the system replacing it will be built on electrons.

The Gigacorn Signal

For investors, this shift matters enormously.

The global energy system is not simply decarbonizing.

It is re-architecting itself around efficiency.

Technologies that replace combustion with electrons do something remarkable: they solve economic inefficiencies, and security risk while reducing emissions at the same time.

That combination is rare.

It creates companies that scale quickly, attract capital, and reshape entire sectors of the economy.

Which is why the most important question in climate investing is no longer:

Will the transition happen?

The question is: Which technologies convert the largest share of wasted energy into useful work?

Those are the companies that scale.

Those are the companies capital will chase.

And increasingly, those are the companies that will define the next generation of industrial giants.

Because when energy becomes more efficient, more secure, and more locally produced, the benefits compound.

Prosperity becomes easier to sustain.

Stability becomes easier to maintain.

And the global economy becomes less vulnerable to the narrow straits and fragile systems that once defined it.
