Episode notes
Focus On 90–95% First
- High shares of wind, solar and batteries can reach 90–95% in many countries at affordable cost.
- The final few percent are costlier and need diverse strategies like long-distance transmission or other low-carbon sources.
Reallocate Effort From Final 5%
- Re-evaluate modelling assumptions that inflate costs for the last 5–10% of decarbonization.
- Consider redirecting funds to decarbonize transport and heat rather than obsessing over the final grid percentage.
Permitting, Not Variability, Is The Bottleneck
- Grid connection delays and outdated permitting systems are a larger bottleneck than generation variability.
- Shifting from first-come-first-served to merit-based queueing speeds deployment of viable projects.
