Headlined by industry-leading organisations

The companies shaping the future of global energy.

Surging demand, geopolitical threats, and the scramble for clean energy are colliding at once

Global energy infrastructure is more exposed than ever, and tech's soaring power demand is only raising the stakes. The task now: meet demand, build energy security, empower emerging economies, and maybe save the planet while we're at it.

Is AI's appetite for energy satiable?

Energy security in an uncertain world

The next generation of clean energy

Smarter grids for a more demanding future

AI is no longer just a software story – it's an energy story. Every new model, every new data centre and every leap in computing power comes with a growing demand for electricity.
The challenge isn't whether we'll keep building better AI. It's whether we can build the energy infrastructure quickly enough to support it.

Smarter grids for a more demanding future

Energy has become a strategic asset. Recent conflicts and disruptions have shown how vulnerable critical infrastructure and supply chains can be.
Keeping the lights on is no longer just about cost, it's about resilience, reliability and reducing dependence on fragile systems.

Renewables will keep playing a major role, but they're only part of the picture. Technologies like green hydrogen, long-duration energy storage and small modular reactors are moving closer to commercial reality and could help meet growing demand while cutting emissions.
