This course provides a technical exploration of how energy enters, moves through, and exits a modern data centre environment. Learners will examine how infrastructure design, operational efficiency, and sustainability initiatives influence energy consumption, resilience, and long-term environmental impact. Through practical discussions and real-world scenarios, participants will explore the complete energy lifecycle within a data centre facility, including electrical utilities, cooling systems, backup power, renewable energy integration, waste heat re-use, and sustainability reporting. The course also examines how organisations can reduce carbon impact, improve operational efficiency, and align energy strategies with broader business and sustainability objectives.We believe organisations of the future will require teams that can combine operational performance with responsible environmental practices. This course helps learners develop the knowledge needed to support more sustainable, resilient, and energy-efficient data centre operations.
