The things that you need to survive and thrive in an emergency fall into broad categories:
- Records: Documents, photographs, and other needed items. I include a moderate amount of cash on hand ($300 or so) in this category.
- First Aid: Medications, drugs, bandages, disinfectants, etc. Nothing elaborate. Simple is better here.
- Heat and cooking: You can live on cold canned goods and MREs, but they are simply not tolerable for more than a day or two. Hot meals are best.
- Light: Flashlights, lanterns, fire, batteries for them, chemlights, and other ways of creating light.
- Tools: People are tool users. Screwdrivers, knife, hammer, hatchet, etc.
- Communications: There are many ways to communicate. Cell phones, radios, flags, spray paint, chalk or grease pencil markings left on buildings, signs stapled to telephone poles, etc.
- Food and water: Obvious. From half liter bottles of water to reverse osmosis, MREs to farming, we need to consider short and long term food and water needs.
- Shelter: Tents, homes, hotels, tarps, even your vehicle. Any way to get out of the weather.
- Security: Weapons, cameras, sensors, rotating watches.
- Energy: Solar, fire, electric, generators, etc. Anything that helps us power our equipment or our selves that is not cooking or heating related.
My latest endeavor is to secure a source of backup power for the new house. I originally was looking at a standby generator. The problem is fueling it for more than a couple of days adds to the logistical complexity of preparedness. The cost of installing such a generator (including buried propane tanks) is in the neighborhood of $10,000-15,000. Then you have to fuel it, and you only benefit from it when the grid is ,down.
Then I looked into solar. An 8kw solar setup with a Tesla wall to get you through the night or cloudy days will generate about 1200 kilowatt hours a month. The system will cost about $20,000 after taking the Federal tax credit into account. There is no fuel needed, and when times are good, you sell power to the electric company which zeroes out your electric bid, thus subsidizing the cost.
So I think that solar is the way we are going to go for our backup power needs.
