This is not just about rooftop panels; it’s about how science, sustainability, and faith can coexist and set the pace for the rest of the world to follow. Vatican City is powered by solar. On May 29, 2025, the Vatican City officially transitioned to solar power, marking a significant shift in the European energy landscape.
The Vatican’s solar shift is a culmination of a political and spiritual mission years in the making. In 2024, the late Pope Francis issued an apostolic letter ordering the construction of an agrivoltaic solar plant to supply the Vatican with energy from Santa Maria di Galeria. On the same site, the new solar infrastructure now stands.
This project was carried out by ACEA, an Italian utility company, which installed systems to meet all of the Vatican’s energy demands. What makes this significant is not the size, but that Vatican City is only 0.49km², and there was no loud campaign, no press tour, just action set in stone and implemented.
“Fratello sole” or “Brother Sun” was Pope Francis’ Apostolic Letter that detailed how solar power is an invitation for people around the world to make lifestyle changes to counter global warming and the “pervasive” use of fossil fuels.
By May 29th, 2025, that vision was fulfilled, and the Vatican City became one of the only fully solar-powered states in the world, setting a clear precedent on how belief and sustainability can align.
The Vatican’s commitment to green energy is further exemplified by its partnership with the utility company Acea, which now supplies the state with electricity exclusively from renewable sources. This shift ensures that all the energy consumed within the Vatican’s walls is entirely green, setting a powerful example for the global community.
The global industrial and commercial energy storage market is experiencing explosive growth, with demand increasing by over 250% in the past two years. Containerized energy storage solutions now account for approximately 45% of all new commercial and industrial storage deployments worldwide. North America leads with 42% market share, driven by corporate sustainability initiatives and tax incentives that reduce total project costs by 18-28%. Europe follows closely with 35% market share, where standardized industrial storage designs have cut installation timelines by 65% compared to traditional built-in-place systems. Asia-Pacific represents the fastest-growing region at 50% CAGR, with manufacturing scale reducing system prices by 20% annually. Emerging markets in Africa and Latin America are adopting industrial storage solutions for peak shaving and backup power, with typical payback periods of 2-4 years. Major commercial projects now deploy clusters of 15+ systems creating storage networks with 80+MWh capacity at costs below $270/kWh for large-scale industrial applications.
Technological advancements are dramatically improving industrial energy storage performance while reducing costs. Next-generation battery management systems maintain optimal operating conditions with 45% less energy consumption, extending battery lifespan to 20+ years. Standardized plug-and-play designs have reduced installation costs from $85/kWh to $40/kWh since 2023. Smart integration features now allow multiple industrial systems to operate as coordinated energy networks, increasing cost savings by 30% through peak shaving and demand charge management. Safety innovations including multi-stage fire suppression and thermal runaway prevention systems have reduced insurance premiums by 35% for industrial storage projects. New modular designs enable capacity expansion through simple system additions at just $200/kWh for incremental capacity. These innovations have improved ROI significantly, with commercial and industrial projects typically achieving payback in 3-5 years depending on local electricity rates and incentive programs. Recent pricing trends show standard industrial systems (1-2MWh) starting at $330,000 and large-scale systems (3-6MWh) from $600,000, with volume discounts available for enterprise orders.
