Dr. Naim Afgan's book Resilience of Energy Systems in Catastrophic Events contains clear exposition of the resilience concept, with application to nuclear, hydropower, coal-fired power, solar, wind, and high voltage transmission energy systems. He offers solutions to the problems inherent in increasingly complex power systems and analyzes the impact on these systems in the event of catastrophic events, both natural and the result of system malfunction, and provides assessment to prevent such events in future with the aim of creating sustainable, secure energy systems. The author's framework for analyzing, developing, and optimizing secure, resilient energy systems provides vital instruction for individuals, communities, and organizations on mitigating and preventing power supply disruptions in order to help achieve energy security and stability for the future.
