The Department of Energy’s annual portfolio of federal funding opportunities (FFOs) — an announcement for the solicitation of research applications on a specific technical area — published on grants.gov declined by more than 45 percent between 2012 and 2017 from 81 FFOs in 2012 to 44 FFOs during the last calendar year. The decline had the most significant impact on the number of FFOs published in technical areas related to renewable energy, energy efficiency, and storage/other energy-related systems.
