What can I do, put solar panels on the roof? Many data-center managers would like to "go green," but they don't know where to start. This presentation identifies areas of waste and inefficiency in the data center. Often, the simplest and cheapest solutions are the most effective. An inefficient data center can waste 250kW to 300kW of energy from the generator room, lighting, environmentals, security system or fire-suppression system. These losses are not core to your operations, they don't support the servers or keep them running, don't keep them cool, don't process data and don't process storage. They just waste energy. Green starts with conservation. Here is practical and low cost advice to help you save energy and money.
