After moving from Calgary, Alberta to Vancouver, Xiyun Hu noticed a drastic difference in the night sky – the stars seemed to have vanished. This realization inspired 17-year-old Xiyun to found the Starry Night Initiative, a youth-led organization focused on reducing light pollution. By 2023-24, the initiative had expanded its reach to more than 20 countries and 30 schools worldwide.
Recognized for her impactful work, Xiyun has received recognition from the United Nations (UN) and has spoken at international conferences such as Catalyst 2030.
What is the Starry Night Initiative?
The Starry Night Initiative is the largest youth-led organization dedicated to reducing light pollution. Its mission includes providing resources for communities to create personalized street lamp covers and launching educational campaigns to help people understand the impact of light pollution on our daily lives and broader impacts on the environment.
Why reduce light pollution?
Hu believes that light pollution harms more than just the view of the stars.
Uncontrolled outdoor lighting wastes billions of dollars annually, contributing to carbon emissions and accelerating global warming.
The disruption extends to wildlife as well. Artificial light disrupts animal and plant circadian rhythms, migration patterns, and growth cycles. In humans, exposure to artificial light at night disrupts melatonin production, leading to sleep disturbances and increased risks of cancer, metabolic disorders, and mood disorders.
Of course, the view of celestial objects is diminished, hindering telescope effectiveness and limiting access to dark skies for astronomers.
Hu added that currently, unshielded street lamps cause light to spill into the sky instead of toward the ground where needed, which is the main cause of light pollution. Correcting this will reduce light pollution significantly.
Reducing Light Pollution: The Light Catcher
The organization’s key innovation is “The Light Catcher,” a cost-effective device designed to significantly reduce light pollution by directing streetlamp lights downward, where it is needed most.
“The Light Catcher is something we’re really proud of,” Hu notes, “It’s a practical and simple solution we hope to see cities adopt around the world. We aim to see a reduction in unnecessary light and help cities achieve a balance between nighttime illumination and darkness.”
By focusing light downward and reducing skyglow, the diffuse brightening of the night sky over populated areas, the Light Catcher can reduce light pollution in unshielded street lamps by 96.5%. With this innovation, the Initiative hopes to reduce light pollution by up to more than 50% total light pollution in urban areas.
Engaging Communities: Awareness and Action
In addition to its technological solutions, the Starry Night Initiative is heavily invested in grassroots efforts. The organization has partnered with over 30 schools, educating younger generations about environmental stewardship and the importance of preservation.
“We believe education is the foundation for long-lasting change. That’s why we focus a lot on working with students,” the founder shares.
By encouraging the next generation to appreciate the night sky’s importance, the Starry Night Initiative is paving the path to a more sustainable future.
The Initiative’s impact is evident through educational workshops, social media campaigns, and community outreach. They’ve reached over 100,000 people globally, with their educational materials and light shield guides– simplified guides that people can use to create Light Catchers at home– distributed to more than 9000 homes. These efforts are supported by an extensive social media presence which amplifies the Initiative’s message, reaching communities globally and encouraging action.
The personal impact it has had on individuals is especially moving. “Many of my classmates have told me that they were able to see the stars for the first time since they were little,” shares the founder. “That’s the kind of feedback that keeps me motivated and reminds me of the importance of what we’re doing.”
Building Partnerships for Global Impact
The Starry Night Initiative recognizes that partnerships are essential for achieving change. The organization has already established collaborations with over five environmental organizations and continues to expand its network. They work closely with local governments and national parks, holding meetings with officials to discuss how they can mitigate light pollution and improve infrastructure in areas where light pollution is especially severe.
“Our goal isn’t just to change the way people think about light pollution, but also to influence policy at a governmental level” explains Hu. “We want to make sure that cities are implementing actual energy-saving measures and better lighting designs that minimize their environmental impact.”
By leveraging these partnerships, the Initiative has implemented energy-saving plans that are projected to reduce energy consumption by 49% in certain regions. These changes not only help the environment by reducing the carbon footprint of cities but also offer financial benefits by lowering energy costs for municipalities.
Legacy for the Future
The Starry Night Initiative is not just about the present– it’s about creating a lasting legacy for the future of society. Its innovative approaches to reducing light pollution, combined with its focus on education, community involvement, and global partnerships, make the Starry Night Initiative a unique and effective organization in the fight against dark sky preservation.
With growing support from schools, communities, environmental organizations, and governments, the Starry Night Initiative is quickly on its way to achieving its goal of reducing the majority of light pollution worldwide. The hope is to restore the beauty of the stars and provide future generations with the opportunity to look up at a truly dark sky.
“Whether it’s installing a light shield at home, raising awareness, or advocating for change, every small action matters.”
Looking ahead, Hu hopes to scale up the Initiative, aiming to work with more cities across the globe to adopt sustainable lighting solutions. The organization plans to expand its technology offerings, improving the Light Catcher’s design and developing new solutions to combat indoor and outdoor lighting issues.
“We want to bring the stars back. Not just for us, but for all living beings on Earth. The night sky is something that should be protected, and we must all work together to preserve it.”
