Innovative Energy Solutions
The Great Energy Challenge grant program, in collaboration with a distinguished group of scientists acting as the board of advisors, awards roughly a half-dozen grants per year. The goal of the grant program is to hasten the growth of promising, global energy solutions as a response to climate change, energy resource constraints and environmental limitations.
The grant program highlights innovative efforts addressing these issues and seeks to help leaders navigate the difficulties of early-stage entrepreneurship. The grant program has a global focus, yet aims to highlight solutions for a specific country or community. These promising endeavors make strides toward alleviating energy poverty, developing new technology and/or identifying the greatest potential for large energy gains.
