>The total energy use of this web of hardware is huge—an estimated 31 terawatt-hours per year. More than 150 individual countries in the world consume less energy annually. It would be interesting if the article stated which countries. >And that power-hungry network is currently increasing its energy use every day by about 450 gigawatt-hours, roughly the same amount of electricity the entire country of Haiti uses in a year.
