Customers and regulators increasingly demand products that minimize energy costs and greenhouse gas emissions. For that reason, energy efficiency is a growing consideration in Cisco product design.

The path to energy-efficient networks begins with devices that operate efficiently. Equally important is the way these devices work together to create systems that result in greater overall energy efficiencies. For example:

  • The consolidation of services onto a single device eliminates the need to power multiple devices.
  • Embedded network services support new and more environmentally and cost-efficient work practices, such as collaboration technologies that reduce travel.

Cisco targets energy efficiency gains in products through a number of strategies, including:

  • Developing standby and power-down modes to reduce power use.
  • Improving the efficiency of power supplies 
  • Cutting power used by Application-Specific Integrated Circuits (ASICs) chips used in most Cisco products

Cisco engages with regulators and industry peers to support the development of standards that help enable effective measurement and comparison of product energy efficiency. Cisco activities have included:

  • Signing the EU Code of Conduct on Energy Consumption of Broadband Equipment
  • Working with the Alliance for Telecommunications Industry Standards (ATIS) to develop standards for networking equipment.
  • Working with industry peers to create a methodology to measure product power consumption at typical networking loads. This has helped Cisco understand where energy is used most in the network with the goal of improving future products.
