History of the Day

Sun Day was first proclaimed in 1978 by U.S. President Jimmy Carter, a strong advocate for alternative energy. His vision was to raise awareness about solar energy and inspire investment in clean, renewable sources of power.

Inspired by Earth Day, Sun Day was initially a U.S.-centric event, but over time, environmental groups and solar advocates worldwide began to observe it. The focus was clear: to promote solar power as a sustainable, long-term alternative to fossil fuels.

🧭 In 1979, Carter famously installed solar panels on the White House roof, sending a clear message: “The power of the Sun belongs to all of us.”

Since then, Sun Day has become a symbol of hope, innovation, and climate responsibility.
