Think of it like the index of a book. It is structured so that synonyms, acronyms, and cross-referencing provide multiple ways for you to access information.
How is it different from the glossary?
The EIA Glossary includes definitions of technical terms. Please use the glossary to find the meanings of words.
What items are included?
The listing includes common and technical terms to meet the needs of the public as well as energy specialists. A-Z Topics lists topics with relevance to a broad cross-section of our Web site's audiences. The items are representative of popular topics or publications, frequent inquiries, or have critical importance to EIA's mission. The index will continue to evolve as terms are added and refined.
