Why this matters
Make the next decision clearer.
Reducing demand is usually the first energy upgrade. Choose the room, devices, lights, meals, and tasks that matter most before buying batteries, fuel, or larger equipment.
Reduce demand first
Choose the smallest safe way to meet the need before adding more equipment or fuel.
Test safely
Read the manual, verify alarms, and practice the setup before you need it.
Put it on paper
A plan you can use and review.
Use this simple table to record the decision, the household-specific detail, and the next time you will test or update it.
| Essential job | Safe source | Test |
|---|---|---|
| Communication and light | Battery lights, power banks, radio, and labeled cables. | Test charging and spare batteries on a routine. |
| Health and food | Only the equipment and loads the household must keep running. | Confirm safe capacity, run time, and backup options. |
| Heat or cooling | Layers, safe rooms, cooling locations, and approved equipment. | Review the plan before seasonal temperature changes. |
