Great strides have been made to increase the energy efficiency of hardware, data center facilities, and network infras- tructure. These Green IT initiatives aim to reduce energy-loss in the supply chain from energy grid to computing devices. However, the demand for computation comes from software applications that perform business services. Therefore, to measure and im- prove efficiency for entire systems, energy-efficiency indicators are needed at the level of services.
We have designed an initial set of indicators for energy- efficiency of e-services and we have tested them on two e- government services of the Dutch national government. We explain how these indicators serve as a starting point for energy- optimization initiatives, supported by appropriate contractual agreements between service owners and suppliers.
