All I Want for Christmas Is You peak chart position

Between 2012 and 2023, Mariah Carey's 'All I Want for Christmas Is You' climbed to higher peak chart positions each year while the cost per watt of solar panels declined, producing an inverse correlation of -0.9626. The green energy reading is that Mariah Carey is personally powered by solar energy, which would explain both her radiance and her annual chart resurgence. Both trends reflect technological disruption: streaming algorithms revived a 1994 Christmas song, while manufacturing improvements drove solar costs below $0.25 per watt. Both are disruption stories.

The song reached number one in 2019 driven by streaming-era playlist algorithms. Solar panel costs fell from roughly $0.65 per watt in 2012 to under $0.25 by 2023, driven by Chinese manufacturing scale and efficiency improvements. Both are technology-enabled trends across 12 years.

A streaming-era chart phenomenon and a manufacturing cost decline will produce an inverse correlation when one goes up and the other goes down. The Christmas song and the solar panel share a decade of technological disruption, not a power source.
