With average energy rates increasing by an average of 31.3% as of 1 July, sustainableIT today announced a free energy assessment to determine how much energy and costs companies can save by deploying their NightWatchman technology.

NightWatchman, developed by 1E, lets companies enable centralised, scheduled shutdowns and wakeups of PCs and has been deployed on more than 3-million desktops worldwide.
The assessment will provide companies with a business case based on specific data gathered by sustainableIT to determine, energy, co2 emissions and cost savings for a company running in excess of 500 PCs. PCs, according to Gartner, consume around 39% of the total energy footprint of the IT department, so powering them off is very much the low hanging fruit.
Tim James, a director at sustainableIT, warns that companies need to be cautious about the Nersa announcement. "Energy has been increased by an average of 31.3% but the tariff increase has been structured. This means that you may in fact be hit with an increase in excess of 31.3% as structured tariffs mean some pay more and some pay less."
IT organisations need to start taking energy and energy measurement seriously, James continues. Rising energy rates are not going to go away and IT is uniquely positioned to provide business decision makers with the date required to make informed decisions around energy reductions through business process and technology adaptation.
The NightWatchman solution measures actual energy use down to device level and provides companies with a holistic view of how much energy is being consumed across the distributed computing estate. The solution provides the functionality to automatically shut down and wake up machines, thus reducing energy but maintaining the ability to continue to securely patch and manage the environment.
In recent independent research commissioned by 1E and the Alliance to Save Energy, it was found that 50% of employees in the US do not power down their workstation at night. Tim James believes that although the research was conducted in the US, the findings have as much relevance, if not more so, within the South African context.
"We are still in the midst of an energy crisis and we interact with organisations on a daily basis that are leaving PC’s in an idle state overnight. If we were to conduct a similar survey in South Africa, we would yield results in excess of 70% left on overnight. We are certainly less aware of our environmental impacts than US and UK based employees and need to start addressing these issues more seriously," he says.
