Cost per watt of solar panels

It is a curious fact, and one that the universe appears to have arranged purely for our bewilderment, that the cost of converting sunlight into electricity moved in almost perfect inverse step with the number of American young adults who found themselves unable to afford converting a spare bedroom into their own living situation. One would think these two phenomena had made a pact to confuse us, shaking hands across the void of unrelated causality.

What likely happened is that both trends were passengers on the same economic vehicle, though sitting in different seats and looking out different windows. As the 2008 financial crisis gutted entry-level wages and housing affordability evaporated like morning dew off a solar panel, young adults moved back home at rates not seen since the post-war era—hitting 35 percent of 18-to-29-year-olds by 2020. Simultaneously, solar manufacturing scaled up across China and elsewhere, driving panel costs from roughly six dollars per watt in 2005 down to about thirty cents by 2022, a drop so steep it's as though someone had been methodically emptying a bathtub while the economy ran in the opposite direction. The hidden engine: economic precarity and technological disruption were both accelerating at once, one trapping young people at home, the other making renewable energy suddenly plausible.

The strange truth is that neither variable caused the other, and yet they waltzed together through seventeen years of American life as if choreographed by someone who had never heard of confounding variables. We are pattern-matching creatures wandering through a world of genuine complexity, occasionally glimpsing something true and more often glimpsing something that merely *looks* true from certain angles. Both datasets were simply caught in the same current.
