According to PG&E, based on customer data and best practice, the three most important things organizations can do to reduce energy consumption are:
- Use outside air*
- Implement hot and cold aisles with monitoring capabilities
- Virtualize servers and storage
- Note: the use of outside air is dependent on location. Worst locale in the U.S. is Tampa Florida (~5% savings). Best locale is Fairbanks Alaska (~65% savings).
