Greening IT often equates to lowering the Total Cost of Ownership of your IT Infrastructure and assets whilst taking advantage of the business benefits Greening technologies deliver. Government and corporate organisations alike have realised they can contribute to improving the environment we live in whilst reducing their bottom line.

Virtualisation and thin client desktop technologies centre on drastically lowering power consumption and cooling requirements through server consolidation and the replacement of high powered workstations with thin client terminals.

Virtualisation represents the best means to reduce power and waste in IT.

The table below shows the potential annual cost savings based on the number of servers that are virtualised. This only shows power and cooling savings, and does not consider the potential savings of reduced hardware and maintenance costs or the reduction in system management overheads.
