Reduces Carbon Dioxide Emissions for Environmentally Friendly Computing
This power management tool makes data centers more environmentally friendly by ensuring that available power and computing loads are in alignment. Data centers are temperature-controlled facilities that house computer systems and components, including servers, power supplies, backup power equipment, chillers, cables, fire and water detection systems, and security controls. All major companies, universities, banks and government institutions have data centers that store information and maintain their computer networks. A single large data center’s energy usage can exceed 30 megawatts (i.e. 30 million joules per second), comparable to the energy usage of a small town. It is estimated that carbon dioxide emissions from computing systems will reach 1.54 metric gigatons by 2020, which would make information technology companies the largest contributors to greenhouse emissions. Available power management schemes adapt computer loads to the time-varying power budget, causing slow job turnaround time and poor service availability. Researchers at the University of Florida have developed a power-management tool that employs a power demand shaping (PDS) technique using load following (online power generation for tracking changes in customer loads) to meet time-variable power demands in distributed generation (DG) systems.
ApplicationA power management tool that controls available power and power consumption in distributed generation (DG) systems, restricting power or providing burst of energy as needed for energy-efficient data centers
- Takes advantage of the load following capabilities of DG systems, avoiding performance costs associated with supply tracking
- Uses energy generated on-site, improving efficiency
- Leverages renewable energy, reducing the use of fossil fuels and curbing carbon emissions from data centers
