AN OVERVIEW OF THE ELECTRICITY USED BY THE GLOBAL DIGITAL ECOSYSTEM
Where Electricity Is Consumed in the Digital Universe
Global Electricity Demand: The Cloud, Illumination, and EVs
The global ICT ecosystem uses as much electricity as global lighting did circa 1985, and in two decades will likely use triple
the energy of all EVs in the world by then, assuming an optimistic 200 million EV forecast.
[“Cloud” is used here to refer to the entire global ICT ecosystem, and not to a more narrow definition of Cloud business services.]
[Red triangles indicate global ICT estimates from Greenpeace. Coal use is based on current global 40% share of electricity generation.]
