Save Energy with Virtualization
A major cost-saving point also saves energy as companies begin to virtualize their data centers. The reduction in physical servers lowers the amount of electricity used in their operations. The amount of heat generated by these systems also sees significant reduction. This allows the company to reduce the costs of cooling the data center.
According to VMware an organization can lower energy costs by up to 80 percent. This reduces the impact on the environment at a rate of four tons of carbon dioxide per server per year. Additionally, where old servers would wind up in landfills with their toxic chemicals and elements, virtualization reduces the number of systems that need to be replaced.
The Green Citizen website indicates that old computers are a source of mercury, lead, cadmium, barium, litium and other heavy metals. It cites a study by Carnegie Mellon that says there are over 70 million computers in US landfills, and these contribute between two and five percent of the solid waste in them. Eventually the chemicals leach from these system and wind up in local water tables.
Virtualization lowers the cost of removing old servers and computers. Companies no longer have to pay to have systems properly recycled to avoid contaminating landfills and ground water.
