Brejo Santo, a city in Ceará, Brazil, is a major dairy hub with over 2,000 milk producers, contributing significantly to the local economy and providing employment. The region is responsible for producing more than 40,000 liters of milk daily, which is transformed into dairy products like rennet cheese, cream, and bottle butter for both local and state consumption. Despite the modernization of milk production, traditional practices are still upheld. However, the cost of milk has escalated due to increased sunlight and rainfall shortages damaging pastures, leading to higher production costs. Despite these challenges, solar panels installed in dairies Valmária and Orlando are aiding in maintaining profitability by offsetting high energy consumption costs.
