The last time the power went out…
- You found out the gas furnace needs electricity too.
- You stood at the open fridge wondering what was still safe to eat.
- You priced generators and got answers from 2,000 to 12,000 watts.
- You weren't sure if that heater was safe to run indoors overnight.
- You told yourself you'd have a plan before the next one.
This manual is that plan, worked out in advance, with the numbers filled in for your home.
One bad outage can cost over $1,000. The manual costs $47.
Typical US costs, not guarantees. Yours depend on your home, area and outage.

Why we made it
Most outage advice online is either a gear review or a doomsday shopping list. Neither tells you what your house needs. We wanted one place with the methods, the safety rules and the math: what heat works without power, what size backup you need, how to keep water and food safe, and what to do in the first hour.
Every number is checked against fire codes and official guidance from NFPA, CDC, USDA and EPA, and carbon monoxide safety runs through every chapter. Off Grid Living Wisdom is an independent channel; no brand paid for or reviewed this manual.
Before you buy
I'm not handy. Is this still useful?
Yes. Most of the manual is decisions and preparation, not building: which heater is safe, what size generator to buy, what to store, what to do in the first hour. Where a job needs a licensed electrician or installer, the manual says so.
I rent. Can I still use it?
Yes. The warm room, indoor-rated heaters (where your lease allows), power stations, water storage, food safety and the outage playbook all work in a rental.
Will it work in my climate?
Yes. Every method is shown with the conditions it suits: cold northern winters, mild southern ones, hurricane season and summer heat waves.
Does it work outside the US?
The methods work anywhere. Codes, units and agencies follow US standards, with metric conversions and notes on where to check local rules.
What format is it, and how fast can I use it?
A PDF you download right after checkout. Open it on a computer, tablet or phone and start with tonight's 20-minute safety steps. The calculators run inside the PDF in the free Adobe Acrobat Reader, and the 7 core calculators also have online versions that work in any browser.
Is this professional advice?
No. It's general information, checked against fire codes and official safety guidance (NFPA, CDC, USDA, EPA). Always follow your equipment manuals and local codes.
