Renewable Capital Race

Solar, wind and battery storage aren't just competing on today's price — they're racing down independent learning curves, each getting cheaper at its own rate as cumulative capacity doubles. This simulator models that race directly: real Wright's-Law cost declines for three technologies, a shared global capital pool that allocates each dollar to whichever technology has the lowest effective cost right now, and policy levers — carbon price and feed-in tariffs — that tilt the effective cost of solar and wind without touching storage at all. Watch three towers grow at different rates as capital, rendered as streaming particles, flows toward whichever technology is winning the race this instant, and see how a policy dial can flip the outcome of a multi-decade cost competition in seconds.
