The original definition of Green IT was the efficient use of computing resources. However, in recent times this definition has been extended to seek ways in which IT can contribute to environmental improvement and the debates about climate change and energy usage.

The Leading Edge Forum (http://www.csc.com) estimate that IT usage in terms of electricity, emissions and recycling consumes only 2% approximately of worldwide energy use. The production of IT components such as PCs and Printers contributes approximately 4% towards the resource usage total in terms of electricity, emissions, recycling, chemicals and water. ...

Environmental sensors monitoring metrics such as temperature and humidity can play a key role in Climate Change projects for providing real-time climate data. The Vertoda system can then take this data and transform it into meaningful information that can be transferred to a desktop Office application, Email, an ERP system, a Business Intelligence system or a mobile phone. The environmental measurement and detection possibilities are many. Water Flow, Soil Degradation and Polllution can all be detected, measured and reported on using WSNs and Vertoda.

As well as measurement/detection, WSNs also play a major role in controlling and managing scenarios where the efficient management of energy is critical. Lighting Systems, Water Management Systems and Filtration technologies require smart sensors for their successful operation. Vertoda will enable IT departments and users to achieve this management through its Sensor Organisation, Alert Configuration and Business Intelligence functions. Its open Web Services API will make this information available to any other software or system that the organisation may use.
