By converting 13.8-kV AC grid power to 800V DC at the data center perimeter, most intermediate conversion steps are eliminated. This reduces the # of fans and power-supply units, leads to higher reliability, improved energy efficiency, and a smaller footprint. spectrum.ieee.org/data-center-dc

No one remembers history. When IBM and Microsoft partnered on OS/2, IBM got upset when a MS employee rewrote some code to be smaller and more efficient because “negative lines of code!”. Measure the wrong thing and you’ll get the wrong behavior. Incentives matter. (╯°□°)╯︵ ┻━┻
