Critical Chokepoints

Five narrow passages through which global energy trade is funneled. Disruption at any one can cascade through world markets.

Strait of Hormuz
Connects Persian Gulf to Gulf of Oman. ~21 million bbl/d transit (~21% of global oil). Bordered by Iran and Oman. The single most important oil chokepoint on Earth.
Strait of Malacca
Links Indian Ocean to Pacific via Singapore. ~16 million bbl/d. Primary route for Middle East oil to East Asia. China receives ~80% of its oil imports through here.
Suez Canal
Connects Mediterranean to Red Sea. ~9 million bbl/d of oil and refined products. Houthi attacks in 2024 forced major rerouting via Cape of Good Hope.
Panama Canal
Links Atlantic to Pacific. ~1 million bbl/d plus significant LNG traffic. Drought in 2023-24 reduced daily transits from 36 to 24, disrupting global shipping.
Cape of Good Hope
Southern tip of Africa. Alternative to Suez Canal, adding 10-14 days. Usage surged in 2024 due to Red Sea security threats. Critical fallback route for global trade.

Oil Logistics & Trade Routes

How crude oil moves from wellhead to refinery to consumer — the physical infrastructure that keeps the world running.

Major Pipeline Networks

Oil Pipelines
Russia → Europe: Druzhba Pipeline (5,500km, 1.2 mb/d capacity). Oldest and longest oil pipeline network in the world. Reduced flows since 2022 sanctions.
Russia → China: ESPO Pipeline (4,857km). Delivers 1.6 mb/d of Russian crude to China. Volume surged 20%+ post-2022 as Russia redirected exports from Europe.
Canada → USA: Keystone Pipeline System (4,324km). Delivers 590,000 bbl/d of Alberta oil sands crude to US Gulf Coast refineries. Trans Mountain expansion (2024) added Pacific export route.
Central Asia → China: Kazakhstan-China Pipeline (2,228km). 400,000 bbl/d. Part of China's strategic diversification away from maritime chokepoints.
Middle East → Mediterranean: Multiple routes including Iraq-Turkey (Kirkuk-Ceyhan), Saudi East-West (Petroline). Alternatives to Strait of Hormuz.
Gas Pipelines
Russia → Europe: Nord Stream 1&2 (destroyed 2022). Ukraine transit reduced. Russia's share of EU gas dropped from ~45% to ~15%. Remaining: TurkStream to southern Europe.
Russia → China: Power of Siberia (3,000km, 38 bcm/yr at full capacity). Power of Siberia 2 via Mongolia under negotiation — would make China Russia's largest gas customer.
Norway → Europe: Multiple subsea pipelines (Langeled, Europipe). Norway became EU's largest gas supplier post-2022, delivering ~30% of EU gas.
Algeria → Europe: TransMed (via Tunisia to Italy), Medgaz (to Spain). North Africa provides ~10% of EU gas.
Central Asia → China: Central Asia-China Gas Pipeline (Lines A/B/C/D). 55 bcm/yr from Turkmenistan. China's largest pipeline gas import source.

Rare Earth Dependency

China's control over the rare earth supply chain that wind turbines depend on:

Neodymium-iron-boron (NdFeB) magnets are essential for direct-drive offshore wind turbines. Each large offshore turbine requires ~600 kg of rare earth magnets. China's 2024 export controls on rare earth processing technology have intensified supply concerns.

Wind Energy Supply Chain

01
Rare Earth Mining
Extraction of neodymium, dysprosium, praseodymium
China share: ~95% of rare earth mining and processing
Other sources: Myanmar, Australia (Lynas), USA (MP Materials)

China share: ~90% of global NdFeB magnet production
Key need: Direct-drive generators require ~600 kg per large offshore turbine
Alternative: Some turbines use gearbox designs that avoid rare earths
03

Onshore: Oversize road transport, specialized cranes
Timeline: Installation of a single turbine takes 1-3 days
08
Grid Connection
Subsea cables (offshore) or overhead lines connect to grid
Offshore: HVDC cables for long-distance transmission; export cables to shore
Bottleneck: Grid connection queues of 5-10+ years in many markets

09
Decommissioning
Turbine removal, site restoration after 20-30 year lifespan
Steel/copper: Fully recyclable (~85-90% of turbine by mass)
Blades: Composite recycling still developing; some go to landfill

Section 05

Energy Consumers

Data centers, AI, and cryptocurrency mining are emerging as massive new sources of electricity demand, reshaping grid planning and energy markets worldwide.

Data Center Energy Demand

415 TWh Data Center Use (2024)
→ 945 TWh Projected (2030)
21% → 44% AI Share of DC Energy
Exponential growth. Data center electricity consumption is projected to more than double by 2030, driven primarily by AI training and inference workloads. This is equivalent to adding the entire electricity demand of Japan.

Tech Company Power Purchase Agreements

Major tech companies are signing unprecedented power deals to secure clean energy for AI infrastructure:

Microsoft
Signed a 20-year PPA to restart Three Mile Island Unit 1 nuclear reactor (835 MW). The first-ever agreement to revive a decommissioned nuclear plant specifically for data center power. Expected online by 2028.
Google
Partnered with Kairos Power for small modular reactors (SMRs) delivering 500 MW by 2030. Also contracted with Fervo Energy for next-gen geothermal power in Nevada. First major corporate SMR commitment.
Amazon
Invested in X-energy SMR technology and signed agreements for over 5 GW of nuclear capacity. Also acquired a data center campus adjacent to the Susquehanna nuclear plant in Pennsylvania.

Section 06

China Dependency Matrix

The clean energy transition depends heavily on Chinese manufacturing and mineral processing. This matrix maps the risk concentration across key supply chains.

Material / Component China Share Risk Level Sector
Graphite (natural, processed) 100% CRITICAL Batteries, EV
Solar wafers >95% CRITICAL Solar
Rare earth mining 95% CRITICAL Wind, EV, Defense
Rare earth magnets (NdFeB) 90% CRITICAL Wind, EV
Gallium ~98% CRITICAL Semiconductors, 5G
Germanium ~60% CRITICAL Fiber optics, Defense
Solar cells >80% CRITICAL Solar
Solar modules >80% CRITICAL Solar
Battery cells (LFP) ~80% HIGH Batteries, EV, Grid
Polysilicon 79% CRITICAL Solar
Cobalt refining 70% HIGH Batteries
Lithium refining 60% HIGH Batteries
Strategic implication: Even where raw materials are mined elsewhere (e.g., cobalt in DRC, lithium in Australia), China controls the refining and processing bottleneck. Diversification requires building entirely new processing capacity, which takes 5-10 years.
Section 07

Critical Minerals

The energy transition is a mineral transition. Every solar panel, wind turbine, battery, and EV requires specific minerals that are concentrated in a handful of countries.

Mineral Top Mining Sources Processing Bottleneck Key Uses
Lithium Australia, Chile, China China 60% refining Batteries (EV, grid storage)
Cobalt DRC (70% of mining) China 70% refining Battery cathodes (NMC)
Nickel Indonesia (50%+), Philippines China, Indonesia Battery cathodes, stainless steel
Graphite China (natural), Mozambique China 100% of processed Battery anodes (100% of Li-ion)
Copper Chile, DRC, Peru China 40% refining Wiring, motors, grid, all electrification
Rare Earths China (95%), Myanmar China 90% processing Wind turbine magnets, EV motors
Uranium Kazakhstan (43%), Canada, Namibia Russia 44% conversion Nuclear fuel
Silver Mexico, Peru, China Distributed globally Solar cell contacts (paste)
Gallium China (~98%) China ~98% Semiconductors, 5G, LEDs
Germanium China (~60%), Canada China ~60% Fiber optics, infrared, defense
IEA projection: Demand for critical minerals used in clean energy must triple by 2030 and quadruple by 2040 to meet net-zero targets. Current mining and processing capacity is far from sufficient.
Section 08

Energy Transition Timeline

Key milestones in the shift from fossil fuels to renewable energy, based on current trajectories and IEA/Ember projections.

$2.2T Clean Energy Investment (2025)
2:1 Clean vs Fossil Spending Ratio
46% Renewables by 2030
2025
Renewables overtake coal as the largest source of global electricity generation. Solar alone adds more capacity than all other sources combined.
2026
Wind + solar surpass nuclear in total electricity generation globally. Nuclear continues to grow, but renewables grow faster.
2027
Solar surpasses wind in total global electricity output. Solar's faster deployment timeline and falling costs drive the crossover.
2029
Solar surpasses hydro to become the third-largest source of electricity after coal and gas. Hydropower growth is constrained by geography and climate.
2030
Renewables reach 46% of global electricity. Combined with nuclear, low-carbon sources exceed 60% of generation. But fossil fuel demand has not yet peaked in absolute terms.
The paradox: Even as renewables scale exponentially, global energy demand growth means fossil fuel consumption remains near record highs through the late 2020s. The transition is an addition, not yet a substitution.
