Each year since 2001, the Gloria Barron Prize is awarded to 25 outstanding young leaders ages 8 to 18 who have made a significant positive difference to people and the environment. This year, we’re pleased to announce that two of those amazing young people received the prize because of the innovative, inspiring ways they use solar power to help people around the world.

Deepika Kurup, age 17, of Nashua, New Hampshire, has invented a practical, low-cost, and sustainable method to purify contaminated water. Her solar-powered device destroys bacteria in wastewater within 15 minutes of filtration and exposure to sunlight. Because it is completely solar powered and its materials do not become depleted, the device can easily be used in developing countries and can be scaled up for large water purification systems.

In addition to winning the Barron Prize, she has two patents pending, and in 2012 was named America’s Top Young Scientist as the national winner of the Discovery Education 3M Young Scientist Challenge. Learn more about Deepika’s inspiration and dedication from her TEDx talk.

Grace O’Brien, age 18, of Rancho Santa Margarita, California, was awarded the Barron prize for her work as the founder of Ears for Years, a non-profit organization that provides solar-powered hearing aids to deaf children in developing countries. She has traveled to Haiti, Honduras, South Korea, and Sri Lanka among other countries to fit over 350 children with hearing aids. She has organized fundraisers and arranged corporate partnerships to raise more than $20,000 and has created multiple high school chapters of Ears for Years to ensure her project continues and grows.

These two fine young people represent the best of what the next American generation has to offer, and we look forward to following their stories as they continue to strive for a positive future for our planet and its people. Other Barron Prize winners for 2015 include:
