US renewable electricity output

America's bowling centers have been closing at a steady rate since the early 2000s, and its renewable electricity output has been rising at a roughly equivalent steady rate, producing a negative correlation of -0.9737 so clean it looks like it was manufactured. The leading theory is that each bowling alley, upon closure, is immediately converted into a solar farm. Investigations have found little evidence of this, but the numbers remain suggestive.

US bowling alleys, already in long-term decline, suffered a brutal 2020 as lockdown orders closed hundreds permanently, while renewable-electricity generation kept rising on policy momentum even as overall demand briefly sagged. The correlation isn't causal — it's two very different trends that both inflected in the year a pandemic reorganized how Americans used their buildings.

The universe contains thousands of things that are declining and thousands of things that are growing, and any decline correlates strongly with any growth over a long enough shared window. This is not a discovery; it is arithmetic.
