CeC

CEC is an acronym that can refer to several distinct concepts, depending on the context. This article summarizes a few widely used meanings in technology, government, and science.

In technology, Consumer Electronics Control (CEC) is an HDMI feature that enables linked devices to communicate and be controlled with a single remote. CEC allows functions such as power on/off, input switching, and volume control to be coordinated across connected devices. Because it is optional and implementations vary by brand, the feature may carry different trade names (for example, Anynet+, SimpLink, or Bravia Sync) in different ecosystems, and not all devices support it.

In government and policy, the California Energy Commission (CEC) is the state of California’s primary energy policy and planning agency. Its responsibilities include setting appliance and buildings energy efficiency standards, supporting energy research and development, approving energy-related programs, and promoting renewable energy and conservation efforts. The commission shapes statewide energy policy, oversees compliance, and informs related regulations.

In soil science, cation exchange capacity (CEC) describes a soil’s capacity to hold and exchange positively charged mineral ions (cations) such as calcium, magnesium, and potassium. CEC influences nutrient availability, soil fertility, and fertilizer management. Soils with higher CEC can retain more nutrients and release them to plants over time.

In Canada, the Canadian Electrical Code (CEC) refers to the electrical safety code that governs the installation and maintenance of electrical systems. It is published by the national standards body and is used alongside provincial and territorial regulations to ensure safe electrical practices.

Other uses exist, but these are among the most widely encountered meanings of CEC.
