Renewable Capital Race (2D)

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 2D build models that race directly, split across three linked panels: a pannable, zoomable capital-flow map where particles stream from a shared global pool to whichever technology has the lowest effective cost right now, a live cost chart tracking real Wright's-Law price declines for all three technologies, and a bank of capacity towers whose height is the base-2 logarithm of cumulative installed capacity — so each full tower-step is exactly one doubling. Policy levers — carbon price and feed-in tariffs — tilt the effective cost of solar and wind without touching storage at all, and a single drag of a slider can flip the outcome of a multi-decade cost competition in seconds.
