Product energy efficiency has long been one of IBM's environment and climate protection objectives. It was formalized as one of the company's corporate objectives when IBM's Product Stewardship program was established in 1991.
IBM's product energy efficiency goal is to continually improve the computing power delivered for each kilowatt-hour (kWh) of electricity used with each new generation or model of a product. In 2012, new server products/models released for which there were previous generation products/models for comparison delivered 10 - 93 percent more computing power for each kWh of electricity used than the previous model/product.
IBM continues to utilize innovations in semiconductor, hard drive/storage system and networking technologies to improve server and storage system performance for each unit of power consumed by the equipment.
In addition to its ongoing program and objectives regarding energy efficient products, IBM has initiated and invested in innovations and integrated solutions involving its hardware, software and services business to address the energy efficiency of IT equipment and the data center.
Beyond its internal focus, IBM continues to actively assist in the development of external product energy efficiency standards. As we did in 1992 when we helped to develop and were a charter member of the United States Environmental Protection Agency (EPA) ENERGY STAR® Computer program, IBM is currently participating in the development of the ENERGY STAR specifications for server, storage and network devices, and providing technical assistance and equipment-operating data to assist in the development of criteria.
