Industrial Energy Use by Subsector (2024)
Energy consumption in EJ
Key Finding: Chemicals 32 EJ (18% of industry)—ammonia, plastics, ethylene energy-intensive. Steel 28 EJ (16%)—blast furnaces use coal/coke. Food & tobacco 24 EJ (14%). Cement 12 EJ (7%)—high-temp kilns 1,400°C. Paper/pulp 10 EJ (6%). Aluminum 4 EJ (2%)—electrolytic smelting. Other manufacturing 66 EJ (37%). Heavy industry (steel, cement, chemicals) 40% of industrial energy but <10% of GDP. Efficiency potential 20-30% with best available technologies.
Transport Energy by Mode (2024)
Energy consumption in EJ
Key Finding: Road 130 EJ (76% of transport)—cars 70 EJ, trucks 45 EJ, buses 8 EJ, motorcycles 7 EJ. Aviation 23 EJ (14%)—growing fastest +3%/year pre-2020, recovering. Shipping 14 EJ (8%)—bunker fuel. Rail 3 EJ (2%)—most efficient per passenger-km. Cars dominant but efficiency improved 20% since 2000. EVs 3 EJ electricity (2% of transport)—but 18% of new car sales. Freight trucks hard to electrify—batteries too heavy for long haul. Aviation hardest—energy density of jet fuel unmatched.
Energy Intensity Decline (2000-2024)
Primary energy per unit GDP (MJ/$2015 PPP)
Key Finding: Global energy intensity fell 5.5 MJ/$ (2000) → 3.8 MJ/$ (2024)—31% improvement. Decline 2.2%/year (2010-2024) accelerating from 1.5%/year (2000-2010). Drivers: efficiency standards (appliances, vehicles), structural shift (services > industry), technology (LEDs, heat pumps). China intensity halved 12 MJ/$ → 6 MJ/$. EU 3.5 MJ/$—most efficient. India 5 MJ/$ improving. USA 4.5 MJ/$. Net zero requires 3%/year intensity decline to 2030. Efficiency cheapest "energy source"—$50/MWh cost vs $30-100 for new generation.
Per Capita Energy Consumption & Inequality (2024)
Energy use per person in GJ by income decile
Key Finding: Global average 77 GJ/capita masks inequality. Top 10% (800M people) consume 165 GJ—primarily OECD, urban elites. Bottom 50% (4B people) consume 25 GJ—sub-Saharan Africa, rural poor. Middle 40% (3.2B) consume 65 GJ. Qatar 800 GJ/capita (highest), Iceland 650 GJ (geothermal abundant), USA 275 GJ. Chad, DR Congo 5 GJ/capita (lowest). Energy poverty: 2B people lack clean cooking fuels, 600M no electricity. Universal basic energy services need +15 EJ but <3% of global consumption.
Understanding Energy Consumption Metrics
Primary vs Final Energy
Primary Energy: Total energy from sources (coal, oil, gas, renewables, nuclear) before conversion. Includes losses. 606 EJ globally (2024). IEA "substitution method" counts renewable electricity at fossil-equivalent—overstates primary, allows comparison.
Final Energy: Energy delivered to end-users after conversion losses. 528 EJ (2024)—13% lower than primary. Gap = power plant inefficiency (coal 35% efficient, gas 50%, nuclear 33%), refining, transmission losses. Electrification reduces primary energy—EVs 3× efficient vs combustion engines.
Useful Energy: Energy actually performing work after end-use losses. ~250 EJ globally. Example: gas boiler 80% efficient, heat pump 300% (per unit electricity). Efficiency gains reduce useful energy needed for same service—why energy intensity declining.
Energy Intensity Metrics
Energy Intensity (MJ/$GDP): Primary energy per economic output. Lower = more efficient economy. Fell 31% since 2000. Varies: heavy industry countries higher (China 6 MJ/$), service economies lower (UK 2.5 MJ/$). Limitations: PPP vs market exchange rates, GDP doesn't measure well-being, climate matters (heating/cooling needs).
Physical Intensity: Energy per unit output (kWh/tonne steel, MJ/passenger-km). Better for tracking technical efficiency. Steel: 20 GJ/tonne (blast furnace) → 9 GJ/tonne (electric arc furnace + scrap). Vehicles: 6 L/100km (2000) → 5 L/100km (2024). Buildings: 200 kWh/m²/year (1990) → 100 kWh/m²/year (new builds in EU).
Sector Definitions
Industry: Manufacturing, mining, construction. IEA includes non-energy uses (feedstocks)—some separate. Energy for: process heat (60%), motors/drives (25%), lighting/HVAC (10%), other (5%).
Transport: Movement of people/goods. Excludes off-road (agriculture, military)—adds ~10 EJ globally. International aviation/shipping "bunker fuels" often excluded from national inventories—attribution problem for climate accounting.
Buildings: Residential + commercial structures. Includes energy for: heating, cooling, appliances, lighting, cooking. Excludes construction energy (counted in industry). Data challenges: informal housing, biomass use (hard to measure).
Regional & Per Capita Comparisons
Per capita consumption correlates with income but huge variation. Norway 200 GJ/capita (cold climate, low pop, heavy industry) vs Switzerland 100 GJ (temperate, service economy) similar income. Singapore 180 GJ (no heavy industry but hot, dense, high electricity use). Climate matters: heating degree days (HDD), cooling degree days (CDD) explain 30-40% of building energy variation.
Energy Poverty Line: 30-50 GJ/capita considered minimum for modern living standards (electricity, clean cooking, heating/cooling, mobility). 2B people below threshold. But consumption ≠ well-being—Costa Rica life expectancy = USA at 40% energy use.
Data Sources & Quality
IEA World Energy Balances: Most comprehensive—covers 180+ countries, all fuels, all sectors. Energy flow "Sankey diagrams" show conversion losses. Updated annually, 1-2 year lag. Purchased data but key figures in free reports.
Energy Institute Statistical Review: Free annual dataset. Primary energy focus, less sector detail. Historical back to 1965. BP Statistical Review until 2022 (brand change).
National Agencies: EIA (USA), Eurostat (EU), NBS (China). More timely but methodology varies—hard to compare. Biomass consumption often estimated (±50% uncertainty)—affects developing country totals. Non-commercial energy (firewood, dung) undercounted—adds 10-15 EJ globally.
