Mettler argues that Europe remains structurally vulnerable due to continued dependencies on imported fossil fuels and foreign clean technologies, and calls for a shift towards domestic production, stronger supply chains and a more strategic approach to industrial policy.
She emphasises that energy must now be treated as a core security and defence issue, with a greater role for institutions such as NATO in accelerating deployment and ensuring resilience.
The interview also highlights a persistent European challenge: scaling clean technologies. While Europe leads in early stage innovation, Mettler points to fragmentation, slow permitting and weak commercialisation as barriers to growth.
The piece reinforces a central Catalyse Europe argument: clean energy is not simply a climate priority, but foundational to economic strength, industrial competitiveness and long term sovereignty.
