Systems Literacy
Infrastructure
Your household sits at the end of five enormous systems: power, water, food, communications, and fuel. Understanding how they work is the quiet foundation of preparedness. A person who knows how the grid balances load reads a rolling blackout differently.

Why this section exists
Know the system, read the failure.
Most preparedness advice starts with what to buy. This section starts earlier, with how things work. Each guide explains one system in plain language: where it comes from, how it reaches you, where it is fragile, and what a disruption actually looks like from inside a household. No alarm, no jargon. Just the mechanics.
When a system has failed somewhere in a way worth studying, the state profiles and failure case studies below the national overviews go deeper.
The five systems
How each one works
The Power Grid
How electricity moves from generation to your outlet, the three interconnections, and what makes the grid vulnerable to weather, attack, and age.
How it worksThe Water Supply
How drinking water moves from source to tap, how treatment works, and what makes water systems vulnerable to drought, contamination, and aging pipes.
How it worksThe Food Supply Chain
How food moves from farm to grocery store, how just-in-time inventory works, and why shelves empty quickly in emergencies.
How it worksCommunications Networks
How cell networks, internet infrastructure, 911, and emergency alerts work, and why communications often fail exactly when they are needed most.
How it worksThe Fuel Supply
How gasoline, diesel, and natural gas move from well to pump, how pipelines work, and why shortages appear quickly and last longer than expected.
How it worksGo deeper
The Texas grid, start to finish.
The archive's first deep trail follows one system into one state and one failure: the national grid overview above, the Texas profile, and the Winter Storm Uri case study.
State profile
The Texas Grid
Why ERCOT stands apart from the national grid, how that isolation shaped the 2021 crisis, and what changed after.

Winter Storm Uri, 2021
The week the Texas grid came within minutes of total collapse. The failure chain, hour by hour, and the reforms that followed.

Every system here has a household counterpart. The energy guides cover backup power, the water guides cover storage and treatment, and the food guides cover a working pantry.
This guide is part of When the Wider World Wobbles, which gathers all the guides for this concern in one place.
