Size Facebook by power usage.
180,000 servers 2018
Based
on data available for total annual power draw for Facebook's data
centers - 509 million kilowatt hours -
and estimates Facebook's average
data center power usage at 58 megawatts of power.
He then applies
Facebook's published Power Usage Effectiveness (PUE) of 1.07 to
conclude
that the social network is delivering 54.27 megawatts to servers, and
divides that by
the power usage of an efficient server. At 300 watts per
server, that works out to about 180,000 servers.
Facebookâs electricity consumption has gradually increased over the last years, reaching 3.43 terawatt hours in 2018. Facebook has set goals to reduce its greenhouse gas emissions by 75 percent in 2020.
In recent years, the company was able to separate growth in the
business from increased emissions, reducing their greenhouse gases from
the previous year. The technology company is also aware of its water consumption and
has committed to a circular system that allows for the reuse of water
consumed. By analyzing their value chain and implementing changes into
the supply chain, Facebook has been able to mitigate emissions from
their operations.
