Oil, Gas & Energy — Seasonality, Routes and Risk
Energy is the one price that shows up inside every other price. This page sets out what oil, gas and electricity normally do through the calendar year, what genuinely pushes them up and down, which sea lanes and pipelines physically carry them, where the weak points are, which countries get hurt first, and what expensive energy does to an economy — the parts that bite within days, and the parts that take years.
What this page is for. It is written for advisory and preparation, not for prediction and not as a trade recommendation. Nobody gets a warning shot before a strait closes, a pipeline is cut or a reservoir runs dry. The point of knowing the seasonal pattern, the routes and the dependency map in advance is that you can act before it hits the fan, while options are still cheap and shelves are still full — instead of discovering the map for the first time in the middle of the crisis.
1 · The board, in USD
All prices on this page are quoted in US dollars, because that is the currency the world actually trades energy in. The board below is live from the same feed the Commodities Analysis page uses.
Units matter more than they look. Crude is priced per barrel (159 litres). US natural gas is priced per MMBtu (roughly a million British thermal units); European gas is normally quoted per MWh, and 1 MMBtu is about 0.293 MWh — so a European price in EUR/MWh and a US price in USD/MMBtu are not remotely the same number even when the gas is identical. Petrol and heating oil trade per US gallon (3.785 litres). Comparing an American headline with a European one without converting both the unit and the currency is the single most common way people mis-read an energy story.
2 · What moves the price — systematically
Energy prices are not mysterious. They are the outcome of a small number of forces, and almost every headline you will ever read is one of them wearing a costume. Split them into four layers: demand, supply, plumbing (the physical middle of the chain) and the paper market.
The two columns. Anything that raises consumption or removes supply pushes the price up; anything that cuts consumption or adds supply pushes it down. The strength of each arrow depends on spare capacity — see below.
2.1 Demand — who is burning it
- Economic activity. Oil demand tracks industrial output, freight and air travel closely. A global slowdown is the most reliable bear force there is, because it removes consumption without anybody deciding to.
- Weather. Cold winters raise gas, heating oil and electricity demand; hot summers raise electricity demand for cooling and, in gas-heavy grids, gas with it. Weather is the biggest short-horizon swing factor in gas and power, larger than most political news.
- Substitution. When gas gets expensive relative to coal or oil, power generators switch fuel where they still can. That switch caps gas prices in normal times — and is exactly what is missing where old coal and oil plants have already been shut.
- Efficiency and structural change. Slow, one-directional, easy to underestimate. Heat pumps, electric vehicles, insulation and industrial closures permanently remove some demand each year.
2.2 Supply — who is producing it
- OPEC+ policy. A cartel decision to hold barrels back or release them is the fastest deliberate supply lever on earth. Read the meeting outcomes, not the pre-meeting rhetoric.
- Spare capacity — the single most important number nobody quotes. It is the volume that could be brought online within about 30 days and held there. When spare capacity is large, disruptions get absorbed and prices barely move. When it is thin, the same disruption produces a violent move. The same news is worth a dollar or twenty dollars depending on this one variable.
- Outages and accidents. Field maintenance, storm shut-ins, fires, strikes, sabotage, sanctions and war. Mostly temporary, occasionally not.
- Investment and decline rates. Producing fields decline every year without new drilling. Money not spent today shows up as missing barrels three to five years out — which is why a long stretch of cheap oil quietly plants the next expensive one.
- Sanctions and embargoes. These rarely remove barrels from the world; they mostly re-route them, lengthen voyages and add insurance and freight cost. That still raises the delivered price even when global production is unchanged.
2.3 Plumbing — getting it from there to here
- Inventories. Commercial stocks and strategic reserves are the shock absorber. Low stocks going into a demand season turn a small disruption into a price event.
- Refining. Crude is not fuel. Refineries convert it, and their margin — the crack spread — can blow out even when crude is flat. A refinery fire raises the price of diesel without touching the price of oil.
- Freight and insurance. When a route becomes dangerous, tanker day-rates and war-risk premiums rise. The cargo is unchanged; the delivered cost is not.
- The US dollar. Energy is priced in dollars, so a stronger dollar makes it more expensive in every other currency even at an unchanged dollar price — and mechanically dampens demand outside the United States.
- Chokepoints. Straits, canals, pipelines and terminals. Covered in detail in sections 4 and 5, because this is where the fragility actually lives.
2.4 The paper market — and the shape of the curve
Far more barrels trade on paper than are ever delivered. That is not a scandal; it is how producers and airlines hedge. But it means positioning and financial flows can move the price for weeks without a single physical barrel changing hands.
The one piece of jargon worth learning is the shape of the futures curve, because it tells you what the physical market is actually short of:
Backwardation
Near-dated contracts cost more than later ones. The market is paying up for barrels now — a sign of physical tightness. Typically goes with falling inventories.
Contango
Later contracts cost more than near ones. Nobody is desperate for barrels today; it pays to store them. A sign of surplus — and in extreme cases, of storage filling up.
Practical use for a non-trader: the curve shape is a free read on whether a price spike is a genuine shortage or a fear premium. A spike with the curve flipping hard into backwardation is physical. A spike with the curve still in contango is mostly nerves — and nerves unwind faster than shortages.
3 · Seasonality — what to expect through the year
Energy is one of the few markets with a physical reason to be seasonal. People heat in winter and drive in summer, refineries shut for maintenance in the quiet months, storage is filled in one half of the year and emptied in the other. That leaves a footprint in the price history — a real one, but a weak one, easily buried by a war, a cartel decision or a recession.
The two charts below are computed live from the actual price history at load time, not typed in from a textbook. For each calendar month we take every month-on-month change in the record, average them, and chain the twelve averages into one typical year. The number of years behind each month is shown, because an average of four Januaries is not evidence.
How to read the hit rate. The average tells you the size of the typical move; the hit rate tells you how often it actually went that way. A month with a +2% average and a 52% hit rate is one big year dragging the average — not a pattern. A month with a +1% average and a 70% hit rate is a pattern. Neither is a guarantee, and we do not draw a line at all when the evidence is too thin to be honest about.
3.1 The calendar, and the reason behind each month
January
Peak heating demand in the northern hemisphere. Gas and power are at their most weather-sensitive: a cold snap has nowhere to hide because storage is already being drawn down. Crude is quieter — the new year brings fresh hedging and fresh budgets.
February
Still heating season, and the month when a genuine cold event does the most damage (frozen wellheads cut supply and demand spikes at the same time). Chinese New Year briefly dents Asian industrial demand. US refinery maintenance turnarounds begin.
March
Heating demand fades, gas storage bottoms out and the injection season begins — the market flips from emptying tanks to filling them. Refiners start buying crude for the summer fuel season.
April
The classic build-up month for crude and petrol: refineries come back from maintenance, and the switch to the more expensive summer petrol blend works its way to the pump. Gas is in its low-demand shoulder.
May
Northern driving season starts in earnest at the end of the month. Alpine and Nordic hydro gets its snowmelt inflow, which softens power prices where hydro is big.
June
Driving demand at full strength; cooling demand starts lifting electricity and, in gas-fired grids, gas. The Atlantic hurricane season opens on 1 June and the risk premium for offshore production and Gulf-coast refining begins to be priced.
July
Peak cooling load in the northern hemisphere; grids run at their annual stress test. Rivers start running low in dry years, which matters for barge freight and for thermal-plant cooling.
August
Hurricane season peaks (August–September). Low water on inland waterways typically bites hardest now. European storage refill is in its final stretch before winter, so any LNG competition with Asia shows up in the price.
September
The turn. Driving season ends, the cheaper winter petrol blend returns, and the second refinery maintenance window opens. Storm risk is still live. Gas begins pricing the coming winter rather than the passing summer.
October
The quiet shoulder for oil demand and the last of the gas injection season. Heating demand has not started but the winter risk premium is now firmly in the gas curve.
November
The withdrawal season starts: gas storage begins to empty. Hurricane season closes on 30 November. Diesel and heating oil demand builds.
December
Full heating season. In the US Gulf, year-end inventory taxes encourage refiners to run crude stocks down, which can distort the weekly statistics. Thin holiday liquidity exaggerates whatever move does happen.
The honest limit of seasonality. In a calm year the calendar above is a decent guide. In a year with a war, a cartel shock, a pandemic or a deep recession, it is worth almost nothing — those forces are an order of magnitude larger than the seasonal tendency. Treat seasonality as a tilt in the odds, never as a forecast, and never as a reason to ignore what is actually happening on the map.
4 · The sea lanes — where it physically comes from
Roughly six out of every ten barrels of oil consumed in the world travel by ship, and essentially all liquefied natural gas does. Ships are cheap and flexible — until they have to pass through a gap a few kilometres wide that somebody can close. Every serious oil price shock of the last fifty years has been about one of the points on this map.
Red numbers are chokepoints; amber lines are the main crude and product sea routes; the dashed amber line is the Cape of Good Hope detour that everything falls back on when the Red Sea route is unusable.
- 1Strait of Hormuz — the single most important passage on earth for energy. In a normal year around a fifth of the world’s oil supply and a similar share of its LNG pass through a channel whose shipping lanes are a few kilometres wide. Saudi Arabia, Iraq, the UAE, Kuwait, Qatar and Iran all ship through it. There is no full alternative: the two bypass pipelines (see section 5) together move only a fraction of the normal flow.
- 2Strait of Malacca — the artery between the Indian Ocean and East Asia, and the busiest oil route in the world by volume. At its narrowest it is under three kilometres wide. Alternatives exist (Lombok, Sunda) but add days and cannot take the full traffic.
- 3Suez Canal & the SUMED pipeline — the short way between the Gulf and Europe. The canal has closed before for years at a time, and the parallel pipeline exists precisely because the canal is a single point of failure.
- 4Bab el-Mandeb — the southern gate of the Red Sea. Close this and the Suez Canal is pointless for Gulf–Europe trade, because nothing can reach it. This is why attacks in the southern Red Sea move European fuel prices.
- 5Turkish Straits (Bosphorus and Dardanelles) — the only way out of the Black Sea. Russian and Caspian crude, on a waterway that runs through the middle of a city of 15 million and is regularly closed by fog and weather.
- 6Danish Straits — the exit from the Baltic, and the route for Russian seaborne crude out of its Baltic ports.
- 7Panama Canal — carries products, LPG and LNG between the US Gulf and the Pacific. It is unique among these points in being limited by rainfall: the locks are fed by a freshwater lake, and in a drought the canal cuts transits and drafts. A weather event, not a political one, throttles it.
- 8Taiwan Strait — the approach to the world’s largest cluster of LNG importers (Japan, South Korea, China, Taiwan). Not narrow, but strategically loaded.
- 9Cape of Good Hope — not a chokepoint but the release valve. When the Red Sea is unusable, cargoes go around Africa: roughly nine to ten extra days from the Gulf to north-west Europe, more fuel burned, more ships needed to move the same volume, and freight rates up for everyone.
The structural lesson. A chokepoint does not have to be closed to cost money. It only has to become risky. Insurers reprice, owners refuse charters, voyages lengthen, and the delivered price rises while global production is completely unchanged. When you read that a strait is “still open”, check the war-risk premium and the number of transits, not the statement.
5 · The pipelines — where it comes from by land
Pipelines are cheaper than ships and far less flexible. A tanker can be redirected mid-voyage; a pipeline goes where it was built, through whichever countries it was built through, and if it stops there is no substitute on the other end. That inflexibility is exactly why pipelines are political.
Blue = gas, amber = oil, dashed grey = built but idle, shut or destroyed. Routes are schematic: the corridor is right, the exact trench is not.
- APower of Siberia (Russia → China) — the flagship of the eastward pivot. Gas that used to have only a European outlet now has an Asian one, though at a price set by a single buyer.
- BCentral Asia – China (Turkmenistan, Uzbekistan, Kazakhstan → China) — the largest gas import route into China, and the reason Turkmen gas never needed to reach Europe.
- CTurkStream (Russia → Turkey, onward to south-east Europe) — after the Baltic routes went dark, this became the main surviving Russian pipeline path toward the EU.
- DSouthern Gas Corridor — TANAP and TAP carrying Azerbaijani gas from the Caspian across Turkey and Greece into Italy. Europe’s only large non-Russian, non-LNG eastern gas route.
- ETrans-Med and GreenStream (Algeria and Libya → Italy) — North African gas under the Mediterranean, plus Medgaz directly to Spain. Politically exposed at both ends.
- FNorwegian export system (Norway → UK, Germany, Poland via Baltic Pipe) — now the largest single pipeline gas source for the EU, which makes Norwegian maintenance schedules a European price event.
- GDruzhba (Russia → Belarus, Poland, Germany, Hungary, Slovakia, Czechia) — the longest oil pipeline network ever built. Partly sanctioned, partly still flowing to landlocked buyers, repeatedly interrupted.
- HBTC and Kirkuk–Ceyhan (Azerbaijan and Iraq → Turkish Mediterranean) — both exist to reach open water without passing a Russian or Iranian chokepoint. That is their entire purpose.
- ICPC (Kazakhstan → Novorossiysk) — Kazakh crude that must cross Russia and then exit through the Turkish Straits. Two dependencies stacked on one route.
- JSaudi East–West (Petroline) and ADCOP (UAE → Fujairah) — the two Hormuz bypasses. They move oil to the Red Sea and the Gulf of Oman without entering the strait. Their combined capacity covers only part of normal Gulf exports, and the Red Sea end has its own risk.
- KESPO (Russia → Pacific coast and China) — the eastern oil equivalent of Power of Siberia.
- LNorth American systems — Keystone (Alberta → US Gulf), Trans Mountain (Alberta → Pacific) and the Trans-Alaska line. Internal to a continent that is a net exporter, which is precisely why North American prices behave differently from everyone else’s.
- ⚊Idle or destroyed — Nord Stream 1 and 2 (damaged 2022, out of service), the Yamal–Europe route through Poland, and the Maghreb–Europe line through Morocco. Built capacity that exists on the map and delivers nothing. A pipeline is only an asset while the politics hold.
Ships versus pipes, in one line: pipelines are cheap, fixed and hostage to whoever they cross; ships are expensive, flexible and hostage to a handful of straits. A country that can only be supplied one way is exposed either way — the useful question is never “is our supply secure?” but “how many independent ways in do we have, and what is the cost of the second one?”
6 · Water, weather and heat — the risk nobody prices until it arrives
Straits and pipelines get the headlines. In practice, a surprising share of energy disruption over the last decade has been caused by something with no politics in it at all: not enough water, or water that is too warm. It hits three separate things at once — transport, cooling and generation — and it hits them in the same weeks, because the cause is the same.
6.1 Rivers as fuel corridors
- The Rhine carries on the order of 200 million tonnes of cargo a year — diesel, heating oil, coal, chemicals, grain — into the industrial heart of Germany, eastern France, the Netherlands and Switzerland. Loading is set by a reference gauge at Kaub, whose long-run average is about 208 cm. Below roughly 77 cm barging becomes structurally uneconomic; around 40 cm commercial traffic effectively stops. The previous record low was 25 cm in October 2018. In the summer of 2026 the gauge fell to single digits — about 6 cm in mid-August, the lowest since records began in 1880 — with barges loading a fraction of capacity and liquid-bulk freight rates from Rotterdam to points south of Kaub rising several-fold in two months (I).
- There is no easy substitute. It takes roughly 60 trucks to replace one 1,500-tonne barge. Europe does not have that many spare trucks or drivers, and rail is already near capacity on the same corridors. A river that stops does not shift to road — it mostly just stops.
- The same story elsewhere: the Danube (riverbed blasting and dredging in Romania in 2026 to keep a channel open), the Mississippi (low water repeatedly restricting the grain and fertiliser barge trade), the Yangtze (the 2022 drought cut Sichuan’s hydro and forced industrial shutdowns), and the Panama Canal, whose locks run on rainwater and which cuts transits in a dry year.
6.2 Water as coolant and as fuel
- Thermal plants need cooling. Nuclear and coal stations that draw from rivers face two limits in a heatwave: too little water to draw, and rules capping the temperature of what they discharge. Output gets curtailed exactly in the week the grid is under maximum cooling load — the worst possible correlation.
- Hydro is a weather derivative with a turbine attached. A dry year in a hydro-heavy system is a direct energy shortfall. Whole national grids run on it: Norway, Brazil, Colombia, Ethiopia, Kenya, Laos, much of Central Asia, and the Zambia–Zimbabwe grid at Kariba, where low reservoir levels have produced some of the longest sustained blackouts of the decade.
- Snowpack is storage. In alpine and Nordic systems the snow that falls in winter is, in effect, next summer’s battery. A warm winter with rain instead of snow moves the inflow forward by months and leaves late summer short.
6.3 The wind and sun version of the same problem
Wind and solar have a weather risk of their own, and it is correlated across a continent. A still, overcast, cold high-pressure system — the Germans call it a Dunkelflaute — can hold wind and solar output near zero across north-west Europe for several days in midwinter, when demand is at its annual peak. Solar output in high latitudes is at its yearly minimum in exactly the months heating demand is at its maximum. This is not an argument against either technology; it is an argument for being honest that a grid is only as strong as its worst simultaneous hour, not its annual average.
The point that generalises: energy risk is not only about hostile actors. Drought, heat and stillness are supply shocks too, they arrive with little warning, and they tend to hit transport, cooling and generation at the same time and in the same place. Any dependency map that only counts politics is missing half the picture.
7 · Electricity — every source has a transport loss and a supply risk
Electricity is not an energy source. It is an energy carrier — a way of moving energy from where it was released to where it is used. That distinction is the whole of this section, and it produces one rule with no exceptions:
Every energy source that has to be carried somewhere as electrical power carries two costs that are easy to forget: a supply risk at the far end of the chain, and a transport loss along the way. Coal has to arrive by rail or barge. Gas has to arrive by pipe or ship. Uranium has to be mined, converted, enriched and fabricated on three continents. Even wind and sun, which arrive free and locally, have to be carried from a windy coast or a sunny desert to a city that is somewhere else — over lines that lose a slice of the power, that can fail, and that cross borders somebody controls. There is no such thing as an energy source with no chain behind it.
The chain, with the losses that are usually left out of the brochure. Percentages are typical ranges, not constants: they vary widely by technology, age, distance and country. The headline number to keep is that between the energy in the fuel and the energy doing work at the socket, a large minority — often a majority — is gone.
7.1 Where the energy actually goes
- Conversion is the big one. A conventional thermal power station turns roughly 33–45% of the fuel’s energy into electricity; a modern combined-cycle gas turbine reaches about 55–62%. The rest leaves as heat. Hydro turbines, by contrast, convert around 90% of what passes through them.
- Transmission and distribution lose roughly 8% of generated electricity worldwide. Well-run grids run 4–7%; weak or over-extended ones lose 15–25%. High-voltage DC lines lose on the order of 3% per 1,000 km plus a couple of per cent in the converter stations at each end — which is why long-distance power transfer is possible but never free.
- Storage costs a round trip. Pumped hydro returns about 70–85% of what you put in; grid lithium batteries about 85–92%; hydrogen used as power-to-power storage returns only about 25–40%. Storing energy is buying insurance, and the premium is paid in kilowatt-hours.
- The LNG chain is the equivalent tax on gas that travels by sea: liquefaction alone consumes roughly 8–10% of the gas, and shipping, boil-off and regasification add several per cent more. Gas that arrives by ship is structurally more expensive than the same gas in a pipe, before anybody argues about price.
7.2 The sources, and what each one is actually exposed to
Hydro
Cheap, long-lived, fast to ramp, and the only large-scale storage most countries have. Risk: drought and snowpack failure, silting of reservoirs, seasonal inflow that may not match demand, and in a dry year no substitute at all. Also a geopolitical risk where the river crosses a border upstream.
Nuclear
High output, steady, low fuel volume, weather-independent. Risk: a fuel chain concentrated in very few countries (section 8), cooling-water limits in heatwaves, decade-long build times and cost overruns, and concentration risk — a single unit is a gigawatt, so one unplanned outage is a national event.
Wind
No fuel, no fuel price, fast to build. Risk: output is a weather variable, correlated across whole regions, and worst in exactly the cold, still, high-pressure conditions that maximise demand. Needs firm backup or storage that is rarely counted in the headline cost.
Solar
Cheapest new generation in most of the world, and it matches daytime cooling demand very well. Risk: it produces nothing at night and least in midwinter — the exact hours heating-dominated grids peak. Also a supply-chain concentration risk in manufacturing.
Gas
The flexibility of the modern grid: it starts fast and fills the gaps everything else leaves. Risk: it is an imported commodity for most of the world, its price is the most volatile of any fuel, and it is usually the plant that sets the electricity price — so a gas shock becomes a power shock even where gas is a small share of the mix.
Coal
Storable on site in a heap that lasts weeks, which is a genuine security advantage. Risk: emissions and the policy attached to them, plus a bulky logistics chain by rail and barge that low water and strikes can cut.
Geothermal & biomass
Firm, weather-independent output where the geology or the feedstock exists. Risk: geographically limited; biomass carries a fuel-supply and land-use chain of its own.
Imports via interconnector
Often the cheapest megawatt available, and the fastest fix for a local shortfall. Risk: it is not capacity you control. In a continental cold snap every neighbour needs it at the same hour, and exports are the first thing a government restricts when its own lights are at stake.
The one-line test for any grid, anywhere: what happens on the coldest, stillest, darkest evening of the year if the largest single unit trips and the interconnector is already at its limit? Every serious electricity crisis is that sentence coming true.
8 · Nuclear fuel — uranium is a fuel, not a perpetual motion machine
Nuclear power is often discussed as though a reactor, once built, simply produces. It does not. A reactor consumes fuel, continuously, and that fuel has a supply chain as long and as concentrated as any pipeline. A typical plant is refuelled every 12 to 24 months, replacing roughly a third of its core each time. Stop the fuel chain and the reactor stops — later than a gas plant would, but it stops.
8.1 Where the uranium comes out of the ground
Share of world uranium mine production. Around three-quarters of it comes from just three countries. Figures are approximate and move a few points year to year (II).
Kazakhstan alone produces about 40% of the world’s mined uranium — a larger share of its commodity than Saudi Arabia has ever held of oil. Canada and Namibia follow, then Australia, Uzbekistan, Russia, China and Niger. Most Kazakh output is extracted by in-situ recovery, which is cheap, and much of it has historically left the country on routes that cross Russia.
8.2 The real bottleneck is not the mine
Uranium out of the ground is useless to a reactor. It has to pass through four more industrial steps, and each step exists in only a handful of places on earth:
- Milling turns ore into uranium oxide concentrate — yellowcake. Done at the mine.
- Conversion turns the oxide into uranium hexafluoride gas. There are only about five commercial conversion plants in the world, one each in Canada, China, France, Russia and the United States (III).
- Enrichment raises the fissile fraction from 0.7% to the 3–5% a power reactor needs. Capacity sits with Russia, China, the United States, the European URENCO consortium and Orano in France. Russia holds on the order of two-fifths of world enrichment capacity — which is why sanctions on Russian energy have consistently carved out nuclear fuel.
- Fabrication presses the enriched material into pellets and assembles fuel rods — and assemblies are reactor-specific. A Russian-designed reactor cannot simply take a Western fuel assembly without a qualification programme that takes years. This is the single most under-appreciated lock-in in the energy world.
So is uranium running out? Not soon, and not in the way oil is discussed — identified resources at current prices are usually put at roughly a century of present demand, and higher prices would make far more of it economic. But that is a statement about geology, not about supply. The binding constraints are the ten-to-fifteen year lead time from discovery to production, the tiny number of conversion and enrichment plants, and the reactor-specific fabrication step. A country can sit on uranium ore and still be unable to fuel its own reactors.
The genuine advantage, stated fairly: energy density. A year of fuel for a large reactor fits on a few trucks, so utilities routinely hold one to three years of inventory in a warehouse. No country can stockpile a year of gas or a year of oil that way. Nuclear’s supply chain is narrow and slow — but once the fuel is in the building, it is genuinely immune to next winter’s weather, freight rate and strait closure. That is a different risk profile, not a smaller one.
9 · Who gets hurt first — exposure by country
The measure below is net energy import dependency: the share of a country’s total energy use that has to be brought in from outside. Red means highly dependent on imported oil, gas or fuel — the countries that feel a disruption first and hardest. Green means broadly independent, or a net exporter. Amber is in between.
| Country / bloc | Import dep. | What that means in practice |
| Singapore | ~98% | Imports essentially all primary energy. Survives on being a trading and refining hub — but has no domestic cushion at all. |
| Malta | 98% | The most import-dependent country in the EU; an island grid on a single undersea link and imported fuel. |
| Taiwan | ~97% | Island, no pipelines, LNG stocks measured in days rather than weeks. Structurally the most fragile large economy on this list. |
| Luxembourg | 91% | No domestic production; entirely dependent on neighbours for fuel and power. |
| South Korea | ~92% | Heavy industry plus almost no domestic fuel. Nuclear provides the only large non-imported block of electricity — and its fuel is imported too. |
| Jordan, Morocco, Lebanon | ~90–95% | Import nearly all fuel with limited fiscal room to absorb a price spike. Where high energy prices turn into subsidy crises and street protest fastest. |
| Cyprus | 88% | Isolated island grid, oil-dominated, with gas discoveries not yet at scale. |
| Japan | ~85–88% | The world’s largest or second-largest LNG buyer by choice of necessity. Everything arrives by sea through the routes in section 4. |
| Italy | ~75–80% | Gas-heavy power mix supplied from North Africa, Azerbaijan and LNG. Exposed to both the Mediterranean and the Gulf. |
| Turkey | ~70–75% | Large importer of both oil and gas, with a currency that amplifies every dollar move in the price. |
| Germany | ~65–70% | Industrial demand, no domestic gas of consequence, and inland waterways that carry the fuel. Exposed on two axes at once. |
| Switzerland | ~70% | Strong hydro and nuclear for electricity, but essentially all oil and gas imported, and dependent on the same Rhine corridor and neighbouring grids as everyone around it. |
| Spain, Portugal, Greece | ~65–75% | High import shares, but large and growing renewable output and several independent LNG entry points — better placed than the raw number suggests. |
| EU as a whole | 57% | Nearly six of every ten units of energy used come from outside the bloc; about two-thirds of those imports are oil and petroleum products (IV). |
| India | ~40% total | The total understates it: roughly 85–90% of crude oil is imported. Domestic coal cushions electricity; transport fuel has no cushion at all. |
| China | ~20% total | Same distortion: domestic coal keeps the total low, while over 70% of oil is imported and almost all of it passes Malacca. Hence the strategic reserve and the pipelines in section 5. |
| Latvia, Sweden, Finland | 27–33% | Among the least dependent in the EU, on hydro, nuclear, biomass and wind. |
| Estonia | 5% | The EU’s lowest, on domestic oil shale. Energy-independent, though not by a route anyone else would copy. |
| Brazil | net exporter | Self-sufficient in crude, hydro-dominated grid, large ethanol industry. Its exposure is to drought, not to straits. |
| United States | net exporter | Net exporter of oil, gas and refined products. Still feels the price — oil is a world market — but not the physical shortage. |
| Canada, Australia | net exporters | Large exporters of oil, gas, coal and uranium respectively. Structurally on the winning side of an energy shock. |
| Norway | net exporter | Europe’s largest pipeline gas supplier and a hydro-powered grid. The clearest example of energy independence in a developed economy. |
| Gulf producers, Russia, Kazakhstan, Algeria, Nigeria, Angola | net exporters | Sell into the shock. Their vulnerability is the mirror image: a price collapse, and in several cases a dependence on imported refined products despite exporting crude. |
EU figures are the published 2024 import-dependency rates (IV); non-EU figures are approximate and given as bands. Dependency is a structural measure, not a forecast of who suffers most in any particular event.
Three warnings about reading this table. (1) Net exporter is not the same as safe — several large crude exporters import most of their refined fuel, and a refinery outage hurts them immediately. (2) A low total can hide a high fuel-specific dependency, as with India and China on oil. (3) Everyone pays the price. Physical supply and price are different exposures: an exporter is protected from the queue at the pump, not from what the world charges at it.
10 · What high energy prices actually do — fast and slow
An energy shock is not one event. It is a sequence, and the parts arrive on very different clocks. Knowing which effects are days away and which are years away is the difference between preparing and panicking.
The transmission timeline. The top band moves before most people have finished reading the news; the bottom band is still moving when the price itself has long since come back down.
10.1 Within days to weeks
- Pump and heating prices. Retail fuel follows the wholesale price within one to two weeks — faster upward than downward, which is a real and well-documented asymmetry, not a conspiracy.
- Freight and air fares. Fuel surcharges are contractual and reprice almost immediately; airline fares follow within weeks where hedges roll off.
- Industrial curtailment. Energy-intensive producers — aluminium, zinc, glass, cement, ceramics, paper, chlorine, steel — simply stop when power costs more than the product is worth. The decision is arithmetic and takes days.
- Fertiliser. Ammonia is made from natural gas, and gas is most of its cost. Ammonia plants shut within weeks of a gas spike — which quietly loads the next planting season, and therefore the food price after that.
- The currency of an importing country weakens as the import bill rises, which raises the local-currency energy price further. Importers get hit twice.
10.2 Within one to twelve months
- Household bills reset as regulated tariffs and fixed contracts roll over — often with a lag of a quarter to a year, which is why the pain peaks long after the headline.
- Headline inflation, then core. Energy enters directly, then indirectly through every transported good, then through wage bargaining. That last step is what turns a price spike into an inflation problem.
- Monetary policy. Central banks face the worst trade-off there is: a supply shock raises prices and cuts output. Whichever they choose, someone is hurt — and interest rates on mortgages and business credit move accordingly.
- Government intervention: subsidies, price caps, windfall taxes, strategic reserve releases, export restrictions. Each helps someone immediately and distorts something else later.
- Demand destruction. People drive less, heat less, fly less. This is the mechanism that ends the shock, and it is not painless — it works by making energy unaffordable for the people with the least slack.
10.3 Over one to ten years
- Industry relocates — permanently. When a smelter or a chemical plant closes because of energy costs, it usually reopens somewhere with cheap energy, not where it was. The price comes back down; the factory does not come back. This is the most consequential and least reversible effect on the list.
- The investment cycle turns. High prices fund drilling, terminals, mines and reactors. Five years later that supply arrives, often all at once, and produces the bust. High prices are the cure for high prices — on a multi-year delay.
- Efficiency and substitution get built. Insulation, heat pumps, electric vehicles, industrial process changes. Slow, boring, permanent — and the only structural defence there is.
- Fiscal divergence. Importing governments borrow to subsidise; exporting ones accumulate. Sovereign credit quality moves in opposite directions on the same event.
- Politics. Energy prices have preceded governmental instability often enough that it should be treated as a normal consequence rather than a surprise, particularly in economies where fuel is a large share of household spending.
The distributional point, stated plainly. Energy is a larger share of the budget the poorer the household, and a larger share of costs the more physical the business. An energy shock is therefore regressive by construction — it is a tax that falls hardest on people and firms with the least ability to hedge, substitute or wait. Any policy response that ignores this simply moves the cost somewhere less visible.
11 · Fusion — when, realistically, and whether ever
Fusion deserves a straight answer rather than either the hype or the sneer, because the honest position sits between them.
Where fusion actually stands. The physics milestone is real and already passed. The engineering and economic milestones are not, and they are the ones that decide whether it ever powers anything.
11.1 What has genuinely been achieved
In December 2022 the National Ignition Facility in California produced more fusion energy from a fuel capsule than the laser energy delivered to it — about 3.15 MJ out for 2.05 MJ in. That is a real, historic result: scientific ignition. The caveat is equally real. Producing that laser pulse drew on the order of 300 MJ from the wall. Scientific gain and engineering gain are different things, and only the second one sells electricity.
11.2 What is still missing
- Tritium supply. The fuel is deuterium and tritium. Deuterium is abundant in seawater; tritium barely exists in nature and decays with a half-life of about 12 years. A power plant must breed its own tritium from lithium in a blanket around the reaction — and no machine has yet demonstrated a self-sufficient breeding cycle. This is a bigger open problem than plasma confinement.
- Materials. Fusion neutrons are far more energetic than fission neutrons and progressively wreck the structure containing them. No material has yet been qualified for a plant lifetime under that flux.
- Duty cycle. Experiments run for seconds. A power station must run for months, restart reliably, and be maintainable by remote handling inside an activated structure.
- Economics. Even a working reactor must produce electricity at a price that competes with solar plus storage and with fission — both of which will also have moved on by then.
11.3 The dates, as they currently stand
- ITER, the international flagship, rebaselined in 2024: research operations now start around 2034, with full deuterium–tritium operation around 2039. It was originally meant to see first plasma in 2025.
- Private compact tokamaks — principally Commonwealth Fusion’s SPARC, using high-temperature superconducting magnets — target net plasma energy gain in the late 2020s, with a first commercial follow-on machine aimed at the early-to-mid 2030s. Timelines here have already slipped once and should be read as intentions, not schedules.
- Other approaches — stellarators, field-reversed configurations, inertial and magneto-inertial concepts — now number dozens of ventures across more than a dozen countries. One has sold a power purchase agreement for the late 2020s. None has delivered a kilowatt-hour to a grid.
The planning conclusion. No fusion plant has ever supplied electricity to a grid, and none is close. Even on optimistic private timelines, first grid power is a 2030s event and any share large enough to change a country’s energy balance is a 2040s or 2050s one. For any decision you face in the next fifteen years — how to heat a building, what to hedge, where to site a factory — fusion is not an input. Treat it as a long-dated option that might pay off enormously and might not pay off at all, and build your plans on technologies that already work.
12 · What to watch, and what to do about it
The purpose of everything above is to be useful before the event. Here is the short list worth checking once a month, and the short list of things that are worth doing while nothing is happening.
12.1 The monthly watchlist
- Spare production capacity. Thin spare capacity turns small news into big moves. This single variable explains most of the difference between a shrug and a spike.
- Inventories against their five-year average — crude, products, and gas storage fill percentage going into the heating season.
- The shape of the futures curve. Backwardation means physical tightness; contango means surplus. See section 2.4.
- Freight and war-risk premiums, and transit counts at the chokepoints in section 4. Transit counts fall long before anyone announces a closure.
- River gauges and reservoir levels in the basins you depend on, and the refinery maintenance calendar.
- Scheduled decisions — cartel meetings, tariff resets, central-bank dates. Known in advance, and reliably under-prepared for.
12.2 What is worth doing in calm weather
- Fix price when nobody is frightened. Contracts are cheapest precisely when the news is boring. Fixing during a spike is buying insurance after the fire has started.
- Buy efficiency rather than forecasts. Insulation, a better heating system, a more efficient vehicle and lower consumption pay out in every scenario, including the ones nobody predicted. No forecast is required for the return to arrive.
- Hold a buffer. A full tank, a filled oil or pellet store, a few weeks of the things that go scarce. Modest, cheap, and it removes you from the queue.
- Count your independent routes. For a household: how many separate ways can you heat and cook? For a business: how many suppliers, and do they share a single upstream chokepoint? One supplier with two contracts is still one route.
- Do not buy into the spike. The most expensive decisions in every energy crisis are made in the first fortnight, by people reacting to a headline with a full-size order.
Framing: none of this is a market call, and none of it requires you to be right about the price. It is about arranging things so that being wrong is survivable — which is the only form of preparation that works, because the specific trigger is never the one anybody wrote down in advance.

13 · Data freshness — checked monthly
Half of this page is live: the price board and the seasonality charts recompute from the market data feed every time the page loads, so they cannot go stale. The other half — volumes, capacities, production shares, project dates — is written text, and written text rots. It is reviewed on a monthly cycle and flagged here.
···
Checking…
- Live, never stale: the USD price board and every number derived from it; the seasonality averages, hit rates and year counts; the date range and row count behind each chart.
- Reviewed monthly: chokepoint volumes and status, pipeline status (which lines are flowing, idle or destroyed), uranium production shares, import-dependency figures, and the fusion project dates in section 11.
- Expected to change: anything in section 11, and the status of any single pipeline or strait. Anything describing a live conflict should be assumed out of date and verified before it is relied on.
If the flag above is amber or red, the written figures are past their review date. The live charts are still current regardless — they do not depend on the review.
