Energy

Overview

Energy is the dependency system.

Every other system in this guide runs on it. Water pumps, medical equipment, communications, refrigeration - none of them function without power. When the grid fails, it does not fail alone. It takes every dependent system with it.

Extended outages measured in days, not hours, are a routine consequence of severe weather, infrastructure failure, and grid instability. The households that manage them well are the ones that understood the system before they needed it.

This guide organizes energy independence around three load categories: Light, Power, and Heat. Each draws from a different part of the system. Each has a different fuel source, a different failure mode, and a different solution.

Keep them assigned correctly and the household functions through an extended outage.

Assign them wrong - run a space heater from a battery, leave comfort loads drawing overnight - and the system collapses faster than expected.

Those three load categories are supported by five operational capabilities. Generation produces energy from grid, solar, or fuel. Storage holds it between generation and use - batteries for electrical, propane tanks for combustible. Conversion transforms stored energy into a usable form. Distribution routes the right source to the right load. Regeneration returns the system to full capacity so the cycle can repeat.

Your Energy Independence Score is the lowest of the three load categories.

The Pre-Flight Check scores your household across Light, Power, and Heat. Doctrine explains how the capabilities work. Field Operations explains how to run them. Loadouts define what to build.

Energy independence is not about producing more power. It is about assigning the right fuel to the right load so the system remains stable under stress.

Failure Modes

Pre-Flight Check

Three categories. Three scores. Your Energy Independence Score is the lowest of the three - you are only as independent as your weakest system. Run the calculator. Your score tells you which loadout to build.

Doctrine

Energy independence is not about producing more power. It is about assigning the right fuel to the right load so the system operates safely, effectively, and efficiently.

Household energy moves through five stages:

Generation

Generation is where energy enters the system. For most households, that source is the grid. It is reliable enough that people stop thinking about it. That complacency is what makes failure disorienting. When the grid goes down, every dependent system fails at the same time.

Solar is the most misunderstood source in the residential market. Most rooftop systems are grid-tied. When the grid drops, the inverter shuts off automatically to protect line workers. The panels may still be producing. You simply cannot access the power.

Solar only works in a grid-down environment if a battery sits between the panels and your loads. Panels feed battery storage. The battery feeds the house. Without panels, a power station runs down once. With panels, it becomes a system.

Generators produce more watts per dollar than any battery solution. If your household relies on a well pump, sump pump, or high-draw medical equipment, a generator is not optional. It is risk control. If you buy a generator, inverter type should be the priority. Conventional units produce unstable voltage that damages modern electronics.

Storage

Storage is the buffer between production and use. When generation stops, storage determines how long your energy system can operate.

Electrical storage is measured in watt-hours (capacity) and watts (output). Capacity determines runtime. Output determines what you can start and run. Size to critical loads first. A 2,000 watt-hour station can cycle a refrigerator, power a CPAP for multiple nights, and charge every device in the house for days.

Combustible storage - propane is energy in chemical form. A full 20-lb tank contains roughly 430,000 BTUs. It does not degrade. It connects to your grill, fireplace logs, camp stove, heater, and generator. Maintain two full tanks at all times. Running out of propane is a planning failure, not a supply problem.

Battery storage keeps your low-draw devices operational. Keep alkaline batteries on hand for any device that accepts them. For long-term storage, lithium disposables have the longest shelf life - up to 20 years. For maximum versatility, invest in solar rechargeable AA and AAA batteries. They eliminate the supply constraint entirely and recharge from any light source.

Conversion

Conversion transforms stored energy into usable energy. A fireplace converts wood into heat and light. A gas grill converts propane into cooking heat. Propane handles thermal demand more efficiently, and at lower cost, than batteries at every price point. Stored electrical power requires an inverter to convert DC into AC.

Distribution

Light runs on dedicated batteries. Every person in the household should have a dedicated headlamp. A multipack covers the household at baseline. Your primary headlamp should have analog controls you can operate without looking, gesture activation for hands-free use, an adjustable beam from spot to flood, and a red light mode. Most importantly, it should run on both a rechargeable battery and disposable AAAs. When the rechargeable dies, you have a backup power source. That is the redundancy you want in premium equipment. Lanterns are low-draw area devices that should remain fully charged at all times when not in use. Solar charging options add redundancy and increase independence.

Power can be sourced from power stations. The power station is the electrical anchor - it runs and charges your most important devices: phones, medical devices, refrigeration, communications. Each critical device in the household should have a dedicated power bank that can be solar recharged. This provides independence, mobility, and eliminates reliance on the power station for small loads.

Physical distribution matters. An extension cord game plan is needed for your critical devices. Twelve gauge wire is the minimum for sustained appliance loads.

Heat is thermal combustion, so distribution is straight from the fuel: propane, wood, or another source.

Regeneration

The energy system requires fuel sources to regenerate and sustain operation. E=MC².

The electrical system can use the sun as a fuel to regenerate and sustain household operations. Solar panels charge batteries during daylight. Batteries carry loads overnight. Repeat. As long as the sun rises, the system continues to operate.

Generators generate electrical energy by using combustion - the burning of a fuel.

Your thermal combustion cycle is limited by supply. The propane supply chain is decentralized, redundant, and typically more resilient than the electrical grid. But once your tanks reach empty, your combustion cycle ceases to operate.

Field Operations

Doctrine tells you how the system works. Field Operations tells you how to run it when the lights go out.

Light

The first thing a power outage takes from you is light. It disappears instantly, and every problem you face in the dark becomes much harder.

Headlamps are for task work. Lanterns are for rooms. Empty rooms go dark.

Every headlamp lives in one known location. Use red light mode after dark and in any shared space - it preserves night vision and does not blind other household members.

Store area lanterns together in a central location that ensures they are always charged. Run lanterns at the lowest setting that makes the room functional. Most produce adequate light at 10-20% output and extend runtime by a factor of four or more at that setting.

Power

The power station stays plugged in and charged at its staged location under normal conditions. On outage, do not delay deployment of the solar panels.

Cycle the refrigerator on a schedule - fifteen minutes on, forty-five minutes off - to keep food safe longer. Charge all devices during daylight solar hours. Phones and critical devices run from their dedicated power banks overnight.

Comfort loads - televisions, gaming systems, decorative lighting - go dark or run only when solar input is actively exceeding critical load demand.

If you have a generator, run it to serve motor loads - well pump, sump pump - and recharge the power station simultaneously. That is the most efficient use of generator runtime. Outside only, every time, 20 feet minimum from any opening in the structure.

Your car is also a backup charging station. A multi-port USB-C car charger in every vehicle turns your fuel tank into emergency power for phones and small devices. Never let your fuel tank fall below half.

Heat

Fireplaces and wood stoves are the best alternative heat sources. If you have no other heat source, create a heat tent in an interior room by covering doors and windows with blankets. If you are using a heat source that burns fuel (propane, kerosene), crack a window and ensure you have an operable CO detector staged within 10 feet.

Maintenance Schedule

Tie checks to events you already have on the calendar.

The Flight Bag

Loadouts

Three tiers. Each is additive - the 7-Day assumes the 72-Hour is complete, and the 14-Day assumes the 7-Day is complete. Assumes household has a working fireplace and outdoor grill. If not, move the 7-Day heat items into your 72-Hour build.

Professional Services

The loadouts above take a household well beyond 14 days without a contractor, a permit, or a five-figure check. The DIY tier covers most disruption scenarios most households will ever face. The shift to professional services happens when the problem changes scale: you want whole-home coverage, automatic failover, or a permanent solution that requires no management after installation.

Permanent energy systems are not Amazon purchases. A whole-home generator requires a licensed electrician, a transfer switch, a fuel line connection, and a permit. A solar-plus-battery installation requires a certified installer, structural assessment, utility interconnection agreements, and municipal permitting. Sizing either system wrong - undersizing for actual load, placing a transfer switch incorrectly, specifying the wrong battery chemistry - creates a system that fails when it matters most. An EPICS assessment gets the specification right before the contractor shows up.
