How can we build out clean energy and infrastructure faster? Is Europe engineering its way to resilience, or pricing itself out of competitiveness? And can we redesign the entire system fast enough to keep up with AI, electrification and rising demand?

This week on Cleaning Up, Michael Liebreich sits down with Hilde Tonne, Chair of Arup and former CEO of Statnett, to explore the hard realities behind the energy transition. From offshore wind and nuclear to grid bottlenecks and data centre demand, Hilde brings a uniquely systems-level perspective shaped by decades leading infrastructure transformation across telecoms, energy and engineering.

They dive into:

Why grid investment, not generation, may be Europe’s biggest constraint
Whether hyperscaler AI companies should foot the bill for massive grid upgrades
The hidden bottlenecks in regulation, permitting and procurement • How ‘total design’ thinking can cut carbon by 40% before construction even begins
Whether electrification makes Europe more resilient, or more exposed

Hilde argues that this transition is no longer just about climate. It’s about security, competitiveness, affordability and economic growth. But achieving it will require rethinking regulation, redesigning infrastructure and the bureaucracy around it, and aligning public and private capital at unprecedented scale.
