Build the Mix
A power grid has one unbreakable rule: supply must match demand every second of the day. Renewables make that a puzzle — solar peaks at midday, wind blows at night, hydro runs steady. Your job is to combine sites so their output matches the curve.

Stack renewable sites so your supply fills the demand curve — no shortfall, no surplus.
Why isn't demand flat? People use power in waves — a morning rise as everyone wakes, a big evening peak when they're home cooking and cooling, and a quiet dip overnight. The target keeps moving, so your supply has to follow it.
