Renewable energy, bright future

Since 2008, we have implemented numerous renewable energy projects, becoming a leader in renewable energy adoption within the healthcare sector. By investing in wind turbines, solar panels and biomass energy, among others, we have achieved energy independence and reduced our carbon footprint by more than 80 percent. Investing in clean energy sources allows our facilities to enhance resilience and ultimately contribute to a healthier planet.
