What You Need to Know About the Global Energy Crisis
Getting your head around the current global energy crisis helps make sense of the contradictions shaping our world right now. Here’s the thing — we’re stuck in a dual reality where fossil fuel consumption and renewable energy rollout are both breaking records at the same time. The crisis that peaked when Russia invaded Ukraine hasn’t gone away. It’s just shifted into something stranger and harder to pin down.
Global energy demand grew 2.2% in 2024, partly because it was the hottest year on record. Cooling demand alone tacked on roughly 0.3 percentage points to that growth, pushing coal, gas, and renewables all to levels we’ve never seen before. Meanwhile, AI and data centres have turned into serious new electricity consumers — something few mainstream outlets are properly covering.
That said, there are real bright spots. For the first time, solar PV became the single biggest contributor to global energy supply growth, making up over 25% of all new supply according to IEA data. Battery storage overtook the largest-ever annual gas capacity additions, hitting 110 GW installed. In the first half of 2025, solar and wind between them met all new global electricity demand growth.
The problem? Emissions still reached a record 37.8 billion tonnes. Even after $2 trillion was poured into clean energy in 2024, the World Economic Forum’s 2025 Energy Transition Index found that energy security actually stalled. The bottleneck isn’t building renewables any more — it’s whether our grids can actually cope with them. Permitting delays, workforce shortages, and rigid infrastructure — those are the real obstacles now.
Geopolitics are making everything harder. In October 2025, China tightened its rare earth export controls — effectively weaponising the very materials the clean energy transition depends on. The United States walked away from the Paris Agreement. Again. And here’s what might be most worrying: over 80% of energy demand growth since 2021 has come from emerging economies, yet more than 90% of clean energy investment goes to advanced economies and China. That gap is a crisis inside the crisis.
- Solar PV now leads global energy supply growth — nearly 700 GW of new renewable capacity went in during 2025, a genuine milestone.
- Emissions are still rising, just more slowly. Growth dropped from 1.2% in 2023 to 0.4% in 2025, but the curve needs to bend much faster.
- Energy security has stalled despite massive spending — grid infrastructure, not funding, is the main bottleneck.
- Critical mineral supply chains, especially rare earths controlled by China, have turned into a new geopolitical front in energy security.
- The gap between where energy demand is growing and where clean investment is actually flowing remains dangerously wide.
The global energy crisis in 2025 isn’t a single problem with a tidy answer. It’s a tangle of contradictions — record renewables alongside record emissions, trillion-pound investments alongside stalling energy security, tech breakthroughs alongside geopolitical fracturing. The trajectory’s bending the right way. Slowly. Whether it bends fast enough — that’s genuinely unclear.
