DOE Green Energy API

The service from the U.S. Department of Energy provides search access to a collection of resources about energy use and conservation. It retrieves listings for a managed collection of resources highlighting key concepts related to energy efficiency and conservation. Its processes emphasize cataloging of resource content and linking of the familiar single-box search interface to a background structure of topics important in the discipline.

API methods support mapping of user keyword queries to terms from a controlled vocabulary built around scientific concepts important to green energy research. This so-called "keyword to concept" mapping converts a free-text search to a managed taxonomy, which allows retrieval of results for related terms, broader and narrower terms, and other highly targeted sematic relationships.
