| Virtualize servers |
- Thanks to specialized software, it’s possible to run a number of “virtual servers” on one physical “host” server, resulting in fewer physical servers to power and cool.
- A university that virtualized just 35 physical servers saved more than $280,000 over 3 years.

- Data center surveys show that up to 30% of servers aren’t doing any useful work, yet they consume electricity 24/7.
- According to the Uptime Institute, decommissioning a single server can save $500 in energy, $500 in operating system licenses, and $1,500 in hardware maintenance costs annually.
