Product energy efficiency

Product energy efficiency was formalized as one of the company's corporate objectives when IBM established its product design for the environment program in 1991. Through the collaboration of IBM Research and our product development teams, we have combined hardware and software technologies to improve the energy efficiency of IT equipment and in turn, data centers.

One of IBM's product energy efficiency goals is to improve the computing power delivered for each kilowatt-hour of electricity consumed for new server products as compared to equivalent, previous-generation products. IBM's latest POWER9TM-based servers, the S922, S924 and E950, improved the work delivered per unit of power consumed — as measured by the Standard Performance Evaluation Corporation (SPEC) Server Efficiency Rating Tool (SERT) — by 30-60% over previous-generation POWER8®-based servers. IBM's next-generation mainframe enterprise platform, the IBM z15, uses 20-30% less power than a comparably configured IBM z14®, and improves computing power delivered for each kilowatt-hour of electricity consumed by 31%.

IBM also has a goal to qualify its new server and storage products to the U.S. Environmental Protection Agency's ENERGY STAR® program criteria where practical, and where criteria have been developed for the specific server or storage product type.

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 gthe energy efficiency of IT equipment and the data center. For more information, please see the "Energy and climate change" section of our latest annual environmental report on our environmental reporting web page for more information.

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.
