Challenge.Gov empowers the federal government and the public to participate together in equitable forms of innovation through prize competitions.

Prize challenges are open and inclusive and they have delivered innovations to address climate change, sustainable infrastructure, and clean water. Many prize competitions are designed to engage students from colleges and universities.

Department of Energy (DOE), the Environmental Protection Agency (EPA), and the National Oceanic and Atmospheric Administration (NOAA) frequently sponsor prize challenges to find innovative ideas related to creating a sustainable environment.

Every year, the federal government awards millions of dollars in cash prizes for innovative ideas. Right now, there are 25 prize challenges with over $38M in cash prizes, including clean energy and green infrastructure.
