1. A method, comprising:
- selecting a task to be performed at a site powered by an AC power grid, said task comprising (i) data processing on a computer system connected to said AC power grid or (ii) manufacturing an article of manufacture on a manufacturing tool connected to said AC power grid,measuring an AC frequency of said AC power grid to obtain a current AC frequency;
said site performing or not performing said task at said site based on said current AC frequency; and
wherein said performing or not performing said task includes;
if said current AC frequency is less than a threshold AC frequency, determining if an additional site powered by connection to an additional AC power grid has sufficient data processing or manufacturing capacity to perform said task;
if said additional site has sufficient data processing or manufacturing capacity, then measuring an AC frequency of said additional AC power grid to obtain an additional current AC frequency; and
if said additional current AC frequency is equal to or greater than an additional threshold AC frequency then transferring said task from said site to said additional site.
