Refreshed National Library of Energy(Beta) Takes on Expanded Role in Disseminating Department of Energy Scientific and Technical Information

by Lynn Davis 29 May, 2014 in

The National Library of EnergyBeta (NLEBeta), a gateway to information across the U.S. Department of Energy (DOE), is taking on an expanded role in providing access to DOE scientific and technical information (STI) with the retirement of the federated search product Science Accelerator.    In addition, the NLEBeta, launched in February 2013, has a redesigned home page and new features that makes it easier to use than ever. 

Developed by DOE’s Office of Scientific and Technical Information (OSTI), the NLEBeta search tool makes it easy for American citizens to find and access information about the Department from across the DOE complex nationwide, without knowing DOE’s organizational structure.    

The NLEBeta integrates and makes searchable disparate and decentralized information collections across DOE.  Users can search hundreds of webpages and 18 databases – a total of 25 million pages – hosted by DOE (; all DOE program offices; the National Nuclear Security Administration; the Energy Information Administration; all DOE staff offices; all DOE field/site offices; and all DOE National Laboratories and technology centers.  DOE’s program offices include Advanced Research Projects Agency-Energy (ARPA-E), Energy Efficiency and Renewable Energy, Environmental Management, Fossil Energy, Nuclear Energy, and Science.

The NLEBeta makes it possible to search all this information via a single search box.  Using federated search and indexing technology, the NLEBeta retrieves relevance-ranked individual site results with links to the sites or databases where the original content can be viewed.

A Roadmap to Geothermal Heat Pump Feasibility

A Roadmap to Geothermal Heat Pump Feasibility

Planning a trip is exciting. I can’t tell you how long my family planned our trip out west.  For so many years we wanted to do this. When we finally hit the road our adventure was more than we could have possibly imagined.  

The landscape was always changing, always beautiful. Cattle ranches stretched out to infinity. Mountain peaks formed by ancient volcanos lined up in rows, one after another. Rivers of black jagged lava flowed over the landscape. We came across rainbow colors of the painted desert, a petrified forest of long ago, and the jaw-dropping expanse of the Grand Canyon. A winding road down from Flagstaff led us into the red cliffs of Sedona and on the cacti-spotted landscape of the Sonoran desert. The further we went, the more we appreciated vast mother earth. 

Our earth has an immense reservoir of geothermal energy that has helped to create this amazing landscape. Geothermal energy is the heat contained within the earth—a clean, reliable, and renewable energy. Department of Energy (DOE) researchers have made great progress harnessing this energy to make our lives better. It can be used as an energy-efficient heating and cooling alternative and can generate vast electric power across the United States.
