Open Energy Information (OpenEI) is a website for policy makers, researchers, technology investors, venture capitalists, and market professionals with energy data, information, analyses, tools, images, maps, and other resources. It was established by the United States Department of Energy on 9 December 2009. OpenEI provides two primary mechanisms for sharing structured information: a semantic wiki (using MediaWiki and the Semantic MediaWiki extension) for collaboratively-managed resources, and a dataset upload mechanism for contributor-controlled resources. In both cases, the resulting data is made available via Linked Data standards whenever possible. Development of the system is led by the National Renewable Energy Laboratory, in collaboration with other national laboratories. OpenEI, as part of the U.S. Department of Energy's effort to make data open, is in the public domain under the CC0 public domain dedication. More information...
