Energy Use By Data Centers

LA Times:

Each month, electricity used to power searches on Google produces 260,000 kilograms of carbon dioxide and is enough to power a freezer for 5,400 years, according to WordStream. The searches use up 3.9 million kilowatt-hours -– the equivalent of 5 million loads of laundry.

A single spam email of the 62 trillion sent each year creates 0.3 grams of carbon dioxide. A Google search for “Soylent Green” spawns the same amount as driving a car three inches.

So spam is responsible for about 20M mt of CO2 each year, or that of about 4 million cars.
