Clean Energy 101: Energy System Resilience

This guide by RMI defines energy system resilience as a community's ability to maintain critical services during and after extreme weather, distinguishing it from reliability, which refers to day-to-day grid performance. The document outlines the necessity of resilience due to climate volatility, aging infrastructure, and increasing grid strain, while highlighting that vulnerable populations and Small Island Developing States (SIDS) are disproportionately affected by outages.

• Energy system resilience is defined as the capacity of a community to keep essential services—including water, communications, emergency response, and hospitals—operational during and after extreme weather events. This differs from reliability, which is the grid's ability to deliver consistent electricity under normal conditions.
• Several factors are currently increasing the need for energy resilience, including more volatile weather caused by climate warming, aging infrastructure not designed for current extremes, the interdependence of power, gas, telecom, and water systems, and increased grid strain from electrification and data centers.
• Power outages disproportionately impact vulnerable groups, such as children, older adults, and people with disabilities, as well as low-income and predominantly Black neighborhoods. Small Island Developing States (SIDS) face extreme economic impacts, with disasters costing them an average of 18% of GDP, compared to a 3% global average.
• Resilience hubs are community spaces—such as libraries, churches, or community centers—that provide critical services during disasters and community connection during non-crisis times. Effective hubs utilize clean energy systems (like solar and battery microgrids), energy efficiency measures to extend "hours of safety," and are located in walkable, trusted sites.
• Strategies to scale resilience include implementing storm-resilient building codes, using electric vehicles as mobile batteries via bidirectional charging, and establishing durable local funding like green revolving funds. RMI has implemented these models through solar and battery microgrids in Puerto Rico, Dominica, and Aspen, Colorado.
