You can photograph a wind turbine blade in landfill.
You cannot photograph 1,000kg of CO₂ from coal.
That visual bias is distorting the climate debate, and it’s costing us time.
In this conversation I’m joined by Michael Barnard, climate futurist and systems analyst who models decarbonisation pathways out to 2100. Michael grounds his work in three filters: technical feasibility, economic competitiveness, and human acceptance. No silver bullets. Just deployment reality.
We explore how electrification, industrial policy, and material substitution are quietly reshaping the global economy, from maritime shipping and steel to mass timber buildings and aluminium production. The through-line is simple but profound: when clean energy becomes the cheapest option, systems move.
Why this matters now: energy security has become geopolitical again. Industrial competitiveness is being redefined by electricity price. Europe is rethinking gas dependence. China is relocating heavy industry to hydro and renewables. And grids everywhere are under pressure to deliver more electrons, more reliably, at lower cost.
What changed my thinking in this discussion:
• Shipping volumes may fall by up to 50% as fossil fuel and iron ore trade declines, reducing maritime fuel demand far more than most assume.
• Mass timber isn’t just a materials story, it’s a steel and cement demand story, with implications for global emissions and trade flows.
• In a fully electrified economy, we need roughly 40–50% of today’s primary energy input to deliver the same services, because combustion is wildly inefficient.
• Wind and solar waste is visible. Coal and gas waste is invisible. The mass difference per MWh is 4,000–8,000x, but outrage follows photographs, not physics.
This avoids techno-utopianism and avoids defeatism. It focuses on economics, deployment and system effects.
If you’re a policymaker, investor, utility executive, industrial leader, or climate professional under pressure to cut emissions without breaking systems, this is for you.
If you’re working on this in the real world, I’d value your perspective.
