“BROTHER SUN” RISES OVER THE VATICAN: Pope Leo XIV Pushes Forward a Historic Solar Energy Mission

In a major step toward a greener Vatican, Pope Leo XIV has officially established the Fratello Sole Foundation — meaning “Brother Sun” — to guide and manage one of the Vatican’s most ambitious renewable energy projects.

The foundation was created through a papal chirograph dated June 1, 2026, and its mission is to help carry out the Vatican’s large-scale solar and agrivoltaic project at Santa Maria di Galeria, the extraterritorial area outside Rome long connected to the Vatican Radio transmission center. The new installation is intended to provide clean energy for both Vatican Radio and Vatican City State.

What makes this project especially meaningful is that it is not just a technical energy plan. It is designed as an agrivoltaic project, meaning solar energy production can coexist with agricultural activity, helping protect the land while generating renewable power. Vatican officials describe the foundation as a sign of hope and an example of how energy production, agriculture, and environmental protection can work together.

The project also continues the vision launched under Pope Francis, especially through the 2024 Motu Proprio “Fratello Sole,” which called for a transition toward a sustainable development model and a stronger commitment to caring for creation. Pope Leo XIV is now moving that vision into a new phase by giving the project a dedicated structure to oversee its construction, management, and mission.

For the Vatican, this is more than a solar farm. It is a statement. At a time when climate concerns, energy independence, and environmental responsibility are being debated around the world, the Holy See is presenting this project as a moral and spiritual commitment. The message is clear: protecting creation is not only a policy goal — it is a duty owed to future generations.

With “Brother Sun” rising over Santa Maria di Galeria, the Vatican is turning one of its historic communication sites into a symbol of sustainability, stewardship, and hope.
