Much Green ICT focuses on computers: servers in the data center and desktops in the office. Don't forget that disk-based data storage, which can cost an organization $25/GB/month, also offers opportunities.

Handling our gear's heat has always been an issue for installations large and small. ICT equipment typical took 1x-2x again more energy to remove its heat as it took to power it in the first place (PUE of 2.0+), driving both energy costs and carbon footprints. Early efforts focused on the two obvious tactics: make both the gear and the air conditioning more efficient. We now see these augmented by innovative new approaches to the problem.

The production of realistic animations and effects sequences requires clusters of computers and mass storage known as "render farms". One approach to strike a balance between availability and energy consumption is to integrate power management tools into workflow. Here are two examples, along with one even more aggressive approach to green rendering.
