Scott Humphreys of eco-Kinetics produced a very useful
Energy Audit of St Vincent’s Primary School in Queensland in 2008. By my calculation this indicates that 26% of the electric at the school is used by ICT. This is comparable to the figure I estimated for the ANU Computer Science Department, which was 30%.
Total Electricity Consumption By Category| Category | Percentage Electricity Consumption |
| AV Teaching | 1% |
| Computer Equipment | 7% |
| Computer Network | 16% |
| Entertainment | 0% |
| External Lighting | 4% |
| Food Prep | 7% |
| Lighting - Admin | 3% |
| Lighting - Classroom | 10% |
| Lighting - Other | 1% |
| Photocopiers | 2% |
| Miscellaneous | 2% |
| Refrigeration | 13% |
| Water Heating | 15% |
| Air Circulation | 0% |
| Airconditioning | 19% |
