ENERGY STAR certified products

IBM has a long history with the U.S. Environmental Protection Agency's (EPA) ENERGY STAR® program. ENERGY STAR is a voluntary program which sets energy efficiency and labeling requirements for different product types to identify and promote energy-efficient products.

IBM was a founding partner in the U.S. Environmental Protection Agency's ENERGY STAR program, and we continue to certify eligible products to its criteria.

In 2021, IBM had five Power9TM-based server models subject to ENERGY STAR criteria, and four of them were certified (models S914, S922, S924, and E950). No IBM Power10 servers released in 2021 were subject to the ENERGY STAR criteria. IBM also had four storage products certified to ENERGY STAR in 2021.

Regulatory Development Activities

IBM actively assists in the development of external product energy efficiency standards. In 1992, IBM became a charter member of the EPA's ENERGY STAR computer program and helped to develop the first ENERGY STAR criteria for personal computers. Since then, we have continued to support the ENERGY STAR program and other regulatory programs to assist in the development of new criteria for certifying server and storage products.

IBM engineers are working with industry peers and technical associations to support the development of harmonized worldwide energy efficiency standards for server and storage products. We are:
