From the rise of renewables and the potential of green hydrogen to a renewed interest in nuclear reactors, energy generation has never been more integral to both technology and society’s advancement.

As demand for energy grows, nuclear is experiencing unprecedented growth from private investment.
Old, restarted fission reactors are powering tech giants’ ambitions, and novel fusion designs and production methods are accelerating their commercialisation. Are we headed into a new atomic age? Or are we underestimating the feasibility of abundant, clean energy?

Atomic renaissance

As our energy sources become more sophisticated, so too does the infrastructure underlying our energy consumption. Power grids are undergoing a transformation as efforts to digitalise, decentralise, and infuse AI into new and existing energy architectures across the globe.
What will this paradigm shift result in when we no longer have a one-way delivery system? And will it deliver on the promise of a more sustainable grid?

Ending energy’s gridlock

With renewable energy generation set to surpass coal for the first time in 2025, solar, wind, and hydro are experiencing a boom in expansion. The appetite for alternative power sources is growing and laying the foundations for further innovation of existing methods as well as future hydrogen systems, but as geopolitics, supply chains, and the climate grow increasingly unpredictable and unstable, will this growth continue?

Clean, cheap, competitive

Every action has an equal and opposite reaction – with energy consumption breaking records year-on-year, what repercussions can we expect as countries, companies, and individuals race to power their economies, products, and lifestyles? The world needs more energy than ever before, and our society must grapple with how to provide it.
