EERE Success Stories

  • EERE Success Story—Solar for the People: Online Marketplace Expands Solar Access Options in Rhode Island

    As the residential solar sector rapidly grows, so do the number of options energy consumers have to choose from when going solar. The process can be complex, but energy consumers in Rhode Island now have the option to go solar through their utility thanks to a first-of-its-kind partnership between EnergySage and National Grid.

  • EERE Success Story—New Software Will Enable Chemical Manufacturers to Optimize Distillation Column Configuration and Save Energy

    New software is being developed by Purdue University in partnership with Dow Chemical Company, Eastman Chemical Company, and ExxonMobil Research and Engineering Company, which will use algorithms to analyze feeds with up to six different components and determine the optimized distillation column configuration.

  • EERE Success Story—Solving the Efficiency Puzzle: New Solar Cells Open Pathway to 40% Theoretical Efficiency

    Researchers from Ohio State University recently took a giant leap toward solving the industry’s efficiency puzzle. With support from the SunShot Initiative’s Foundational Program to Advance Cell Efficiency (F-PACE), Ohio State researchers are layering three different materials—gallium indium phosphide (GaInP), gallium arsenic phosphide (GaAsP), and silicon (Si)—within a cell to create an efficiency level greater than 40%. Called an epitaxial Si triple-junction solar cell, the materials are connected in tandem within each cell in a single process.

  • EERE Success Story—Collaborating on Regulatory Processes for Hydropower

    Take a team of hydropower experts from the Energy Department and its national laboratories, led by the National Renewable Energy Laboratory (NREL). Add close collaboration with federal and state regulatory agencies, including the Federal Energy Regulatory Commission (FERC), and other hydropower industry stakeholders. Top it off with a wiki-based platform of an easy-to-access hydropower permitting and regulatory roadmap that covers everything from small and large conventional hydropower to run-of-river hydropower, in-conduit, and pumped-storage projects information. What do you get? The U.S. Department of Energy Hydropower Regulatory and Permitting Information Desktop (RAPID) Toolkit.
