implementation of solar energy in st. catherine PARISH, PAGBILAO
St. Catherine of Alexandria Parish in Pagbilao, led by Msgr. Noel Villareal, has taken a significant step towards sustainability and environmental stewardship by adopting solar energy. This case study explores the impact of this transition on the parish’s energy consumption and its broader implications for community engagement in climate action.
BACKGROUND
The parish experienced high energy consumption due to extensive outdoor and indoor lighting, security systems, powerful sound systems, and air conditioning in response to the increasing temperatures attributed to climate change. The rising energy demand resulted in considerable electricity costs, which prompted the parish to seek alternative energy solutions.

IMPLEMENTATION
The decision to install solar panels was driven by both environmental concerns and financial considerations. Before the installation, the church’s monthly electricity expenses were around PHP 40,000. Post-installation, there was a notable decrease to PHP 28,000 to 30,000, achieving savings of approximately PHP 10,000 to 12,000 per month.
Challenges & Solutions
The initial cost of solar panel installation was a significant challenge. The parish addressed this through fundraising and by obtaining grants from environmental NGOs that support renewable energy projects. Educating the community about the benefits of solar energy also required effort, which was facilitated through workshops and sermons that integrated environmental stewardship with spiritual teachings.

Cost Savings
The significant reduction in electricity bills is equivalent to an increase in the church’s income, allowing more funds to be allocated to other community services and projects.

Environmental Impact
By switching to solar power, the parish has reduced its carbon footprint, contributing to the mitigation of climate change. This move aligns with the global call for renewable energy adoption to decrease reliance on fossil fuels, particularly coal-fired power plants which are a major source of carbon emissions in the Philippines.

Community Leadership & Advocacy
The parish’s solar initiative, aligned with Pope Francis’s 2015 climate change encyclical, serves as a community model and part of the CBCP’s national action plan to promote renewable energy in religious communities.
