The awards are administered by the Texas A&M Energy Institute, the MIT Energy Initiative (MITEI), and the Stanford Precourt Institute for Energy, who collaborate with the U.S. Department of Energy to implement the U.S. C3E Initiative, which aims to close the gender gap and increase the participation, leadership, and success of women in clean energy fields.
