I stumbled upon a very cool Green IT impact calculator from SAP the other day during a conversation with Timo Stelzer, Global VP of SAP Green IT. This one week old calculator shows companies impact of energy cost savings through system consolidation of SAP systems.
At the max, if a company is currently running 50 SAP ERP systems with one client each and they reduce them down to one system with 50 clients they can potential reduce their energy consumption by 1.2million euros in over five years! This number is based on a company that has a 5% increase of energy cost per year and an average utilization of their systems at 40%.
Since this really is a new tool, it is still sitting on SAP’s internal portal, so I can’t provide the calculator to play with. But it will be available in April on www.sap.com/greenit.
The results are not 100% guaranteed, but gives a good baseline of cost savings. The methodology behind the calculator is based on the recent model SAP has developed to estimate the carbon footprint of SAP products in use.
