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 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. New server models released in 2010, for which comparable products existed, delivered from 58 to 98 percent more computing power for each kilowatt-hour (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.
