Key Growth Drivers
- Electricity Demand Surge — Global electricity consumption rose by nearly 1,100 TWh in 2024 — more than twice the annual average of the previous decade — driven by record temperatures, EV adoption, industrial electrification, and AI data centre power demand, according to the IEA.
- Clean Energy Investment Dominance — In 2025, $2.2 trillion is expected to flow to clean energy (renewables, nuclear, grids, storage, efficiency) — twice the $1.1 trillion going to oil, gas, and coal combined, per IEA World Energy Investment 2025.
- Natural Gas Bridge Role — Natural gas saw the strongest demand growth among fossil fuels in 2024 (+115 bcm), reinforcing its role as a transition fuel as markets shift from coal toward gas and renewables.
- Energy Transition Policy — The US Inflation Reduction Act, EU Green Deal, and equivalent policies globally are directing unprecedented capital flows to clean energy infrastructure, grid modernization, and low-emissions industrial processes.
- AI Data Centre Power Demand — The rapid expansion of AI training and inference infrastructure is creating a new, fast-growing source of electricity demand that is accelerating grid investment and energy procurement activity.
Industry Challenges
- Grid Infrastructure Gap — Electricity transmission and distribution infrastructure requires massive investment to handle the shift to renewables and the surge in electricity demand. Grid build-out is constrained by permitting timelines and capital availability in many markets.
- Critical Minerals Supply — Clean energy technologies (batteries, wind turbines, EV motors) require significant volumes of lithium, cobalt, nickel, and rare earth elements whose mining and processing capacity is concentrated in a small number of countries.
- Fossil Fuel Transition Risks — As the energy transition accelerates, traditional fossil fuel assets face stranded asset risk, creating balance sheet vulnerabilities for producers who delay diversification.
How Businesses Use Energy Industry Statistics
- Capital allocation — Energy companies and infrastructure investors use IEA investment forecasts to prioritize capital between clean and fossil fuel segments over multi-year planning horizons.
- Procurement strategy — Industrial companies use electricity demand and price trend data to plan long-term energy procurement agreements and on-site generation investments.
- Regulatory planning — Energy producers and utilities use IEA policy scenario data to model how carbon pricing, renewable mandates, and efficiency standards may affect future revenues and costs.
- Technology development targeting — Energy technology vendors use sector growth data to identify which sub-markets (battery storage, grid software, green hydrogen) offer the highest growth and commercial potential.
- Competitive benchmarking — Energy companies benchmark their investment mix between clean and fossil assets against sector peers and IEA energy transition benchmarks.

According to the IEA Global Energy Review 2025, global energy demand grew by 2.2% in 2024 — faster than the average rate over the preceding decade. Electricity demand was the leading driver, growing 4.3% (1,100 TWh), driven by record temperatures, EV adoption, AI data centre power demands, and industrial electrification.
The IEA World Energy Investment 2025 report states total capital flows to the energy sector are set to reach $3.3 trillion in 2025. Of this, $2.2 trillion is directed to clean energy (renewables, nuclear, grids, storage, efficiency and electrification) — double the $1.1 trillion going to oil, gas, and coal combined.
Natural gas saw the strongest demand growth among fossil fuels in 2024, with consumption increasing by 2.7% — equivalent to 115 billion cubic metres (bcm) — according to the IEA. This far exceeded the decade-long average increase of around 75 bcm per year, reinforcing natural gas's role as a bridge fuel.
AI data centre expansion is creating a fast-growing new source of electricity demand. The IEA notes that electricity demand grew 4.3% in 2024, well above the 3.2% growth in global GDP, with digitalization (including AI infrastructure) cited as a key driver alongside record temperatures and EV adoption.
Key challenges include the need for massive grid infrastructure investment to handle growing electricity demand and renewable energy integration, concentration of critical mineral supply chains (lithium, cobalt, rare earths) in a small number of countries, and stranded asset risk for fossil fuel producers as the clean energy transition accelerates.
