No country on Earth is currently powered entirely by renewable energy on a daily basis, but that is poised to change soon.

In a groundbreaking move, Pope Francis announced on June 21 his ambitious plan to transition Vatican City to 100% renewable energy, primarily through the use of solar panels. This announcement, made in an apostolic letter titled "Brother Sun," reflects the pontiff's ongoing commitment to addressing the global climate crisis and setting a powerful example for the world.

The letter, issued "motu proprio," which means on his own initiative, outlines Pope Francis' vision for transforming the energy landscape of the Vatican. The centerpiece of this plan is the use of Vatican City's multi-purpose land holdings located 11 miles outside of Rome, in an area known as Santa Maria di Galeria.

This area is not only home to some agricultural activities but also houses the essential infrastructure for broadcasting Vatican Radio. The land is vast enough to accommodate a significant number of solar panels, which could potentially generate enough electricity to power the entire Holy See.

Pope Francis has long been a vocal advocate for taking the climate crisis seriously. His call for action has been consistent, urging nations and leaders around the world to prioritize the joining environment and implement sustainable practices.

In 2022, the Vatican took a significant step by joining the United Nations Framework Convention on Climate Change (UNFCCC), a global agreement aimed at addressing "dangerous human interference with the climate system."

This move underscored the Vatican's commitment to the international effort to combat climate change. However, Pope Francis has not only acted through official channels; he has also been outspoken individually, often emphasizing the moral imperative to protect the environment.

In 2023, The New York Times reported on Pope Francis' stance, noting, "The pope identifies the burning of fossil fuels as the primary driver of climate change... He dismisses those who deny the crisis, and accuses wealthy individuals, corporations and countries of selfishly turning a blind eye."

This statement highlights the pontiff's unwavering belief in the urgency of addressing climate change and his willingness to challenge those who contribute to the problem while refusing to acknowledge it.

The timing of the "Brother Sun" letter was symbolic, as it was released on the summer solstice, a day traditionally associated with the power of the sun. Ironically, much of Italy, particularly the northern regions, experienced rain and clouds on that day. Nonetheless, the message of the letter was clear: the Vatican is committed to leading by example in the fight against climate change.

By transitioning Vatican City to 100% renewable energy, Pope Francis is not only addressing the environmental needs of the world's smallest country but also sending a powerful message to the global community. This initiative serves as a reminder that even the smallest nations can take significant steps toward sustainability and that leadership in the climate crisis does not depend on size or wealth but on the willingness to act with conviction.
