01 — Where we are
From niche to dominant in one generation.
Three exponential curves are reshaping the global economy: renewable generation, energy storage, and electrification of transport. Each follows the same learning-rate dynamics that drove semiconductors — predictable cost declines for every doubling of cumulative production.
Solar PV at $0.36/kWh
10× more expensive than coal in most markets.
Paris Agreement
196 nations pledge to limit warming to well below 2°C.
Cheapest electricity in history
Solar PPAs sign below $0.02/kWh in MENA & Chile.
EVs cross 18% of new car sales
China and EU lead global adoption.
Renewables surpass coal
For the first time, renewables generate more global electricity than coal.
Triple renewables target
COP28 commitment: 11,000 GW installed renewable capacity.

03 — The Cost Revolution
Learning curves are unforgiving — for fossil fuels.

07 — Outlook
The transition is no longer a question of if.
It's a question of speed, equity, and infrastructure. Clean technology is now the default economic choice for new electricity generation in nearly every country on earth — but unlocking the full system requires grids, storage, transmission, and policy at unprecedented scale.
