Energy system resilience is broadly defined as the ability to recover from shocks whilst being able to deliver the required energy service needs via alternative means. Whereas robustness is the system’s ability to withstand shocks without significant loss of the ability to deliver those services. These two characteristics are critical aspects to consider for a net zero energy system. As the energy system becomes more complex, distributed, and interdependent between vectors, it creates new challenges and opportunities to deal with increasing risks from natural and other hazards.
