The Energy Transition Debate: Addition, Innovation, and Equity
November 4, 2025On 30 October 2025, ETH Zurich hosted a compelling edition of its Global Lecture Series: Powering Change – The Energy Transition in Practice. Moderated by Chris Luebkeman from ETH Zurich’s Strategic Foresight Hub, the discussion brought together two inspiring women speakers: Bettina Bachmann, a veteran energy executive with over three decades of experience at Shell and an advocate for Women in Tech, and Lint Barrage, ETH economist specialising in climate and energy policy.
The conversation went far beyond technicalities. It explored the realities behind the energy transition, challenging assumptions and highlighting what truly matters: adding energy to meet global demand, driving innovation beyond technology, and ensuring equity across nations. Here’s more in the shape of 5 key takeaways and stand-out quotes from our guest speakers:
Energy Transition: More Than Replacement
“Adding energy is often forgotten in this conversation,” Bachmann reminded the audience. “We cannot just replace fossil fuels; we have to grow at the same time.” Her point was clear: with global energy demand rising, the transition is not a simple swap—it’s an expansion.
Urgency and Continuum
Barrage offered a sobering perspective: “We’ve been too slow for decades. If we had started gradual action earlier, the same level of climate protection could have been achieved at a much lower cost.” Climate action, she stressed, is not binary. Every tonne of emissions avoided today reduces future harm tomorrow.
Innovation Beyond Technology
Both speakers agreed that technology alone won’t solve the problem. “We’re not waiting for a silver bullet,” Bachmann said. “We have the technologies—we need to scale them up and integrate them.” Barrage added that innovation must extend to finance, policy, and behaviour: “People respond to incentives. We need to make clean tech massively more profitable to redirect R&D.”
Global Equity
The panel underscored the ethical dimension: developing nations must leapfrog polluting paths. “We have a duty to ensure they don’t have to go the same hard, slow path that we did,” Bachmann said. Barrage pointed to creative financial instruments as key: “We need smarter ways to leverage private investment and reduce risk.”
No-Regret Actions
Both experts closed with practical advice. Bachmann urged: “Think hard before you replace something—whether it’s clothing or heating systems. Avoid waste.” Barrage’s top three? “Invest massively in innovation, provide better information on energy use, and price carbon where feasible.”
