Abstract

Attention
paid to energy efficiency in data centers has been increasing
significantly in the last decade. One of the latest trends on this issue
is supplying data centers with renewable energy. Reducing the carbon
footprint of data centers is a major step towards green computing.
Following this trend, more and more data centers are built in cold
climate areas for cheaper cooling and increased energy efficiency of the
facilities. However, such geographical locations have highly varying
availability of renewable energy (especially solar energy), and fitting
the data centers completely with renewable energy is hence more
difficult.

This paper analyzes the feasibility of
using renewable energies for a data center located on 60° north
latitude. For this purpose, we introduce a new metric called Minimum
Percentage Supply, which represents the fraction of the total data
center energy consumption that renewable energy, produced by 1 wind
turbine and 1 m2 solar panel, can cover. After estimating the
available renewable energy provided for the city of Turku, Finland, and
the energy consumption caused by the server workload, a feasibility
study is conducted for a data center powered by renewable energy on such
a location. We also analyze the ratio between number of wind turbines
and m2 of solar panels to achieve a desired percentage of
renewable energy coverage for a given data center. Finally, the energy
cost trade-off is evaluated for different quantities of wind and solar
energy sources.
