The 30-Day Preparedness Philosophy
One month of self-sufficiency represents a different mindset than shorter-term preparedness. You're not just "riding out" an emergency—you're establishing systems that could theoretically continue indefinitely.
At 30 days, the question shifts from "how much do I store?" to "how do I produce/maintain?":
- Water: Storage becomes impractical alone. Filtration and potential sources matter.
- Power: Fuel storage is substantial. Solar becomes nearly essential.
- Food: Variety and nutrition become critical for health and morale.
- Health: Minor issues can become major without resupply. Prevention matters.
Real-World 30-Day Scenarios
What actually requires 30 days of self-sufficiency?
- Puerto Rico, Hurricane Maria: Much of the island without power for weeks to months. Rural areas waited 30+ days for meaningful relief.
- Remote Alaskan communities: Weather can prevent resupply for weeks at a time. 30-day preparedness is baseline.
- 2020 pandemic supply disruptions: Certain supplies unavailable for weeks. Those with 30-day stocks never faced empty shelves.
- Economic disruption: Job loss, banking issues, or financial crisis. 30 days of supplies provides breathing room.
Family of 4: Example 30-Day Supplies
Water (120+ gallons + production)
- Primary storage: 120 gallons minimum (4 × 30)
- Options: 55-gallon drums (2-3), multiple 7-gallon containers, WaterBOBs
- Filtration: Berkey or similar gravity filter (2,000+ gallon capacity)
- Backup: Sawyer filter, purification tablets, backup sources identified
- Rainwater collection system if legal/practical in your area
Food (240,000 calories)
- Grains/Starches: 50+ lbs rice, 20+ lbs pasta, 20+ lbs oats, 10+ lbs flour
- Proteins: 50+ cans (chicken, tuna, salmon, beans, spam), dried beans 20+ lbs
- Canned goods: 100+ cans vegetables, fruits, soups, stews
- Freeze-dried: 30 pouches per person (120 total)
- Fats: Cooking oils (5+ liters), peanut butter (10+ jars)
- Comfort: Coffee, tea, cocoa, honey, candy, chips, seasonings
- Vitamins: Multivitamins for each person (nutritional insurance)
Power System
- Primary: 2,000-3,000Wh power station or multiple smaller units
- Solar: 600W+ of panels (can be 3×200W or 6×100W)
- Backup generator: For cloudy periods or high-demand needs
- Fuel for generator: 20-30 gallons stored (for occasional use only)
- Battery stock: 100+ AA, 50+ AAA, 24+ D cells
Cooking & Heating Fuel
- Six to eight 20lb propane tanks
- Camp stove with 40+ butane canisters as backup
- Propane heater for cold weather (Mr. Heater Buddy or similar)
- Charcoal: 80+ lbs if using grill cooking
Extended Duration Essentials
- Medical: 60+ day medication supply, comprehensive first aid, OTC medicines
- Hygiene: 30+ rolls toilet paper, soap, shampoo, toothpaste, feminine products
- Sanitation: Portable toilet, waste bags, sanitizer, lime for waste treatment
- Mental health: Books, games, projects, exercise equipment
- Security: Appropriate for your situation and comfort level
- Cash: $500-1,000 in small bills
- Tools: Basic repair and maintenance tools
The Solar Imperative
At 30 days, solar power shifts from "nice to have" to "nearly essential":
⛽
Generator-only approach:
8 hrs/day × 30 days = 240 hours
At 0.5 gal/hr = 120 gallons of fuel
Storage, rotation, and cost become significant

☀️
Solar + battery approach:
600W panels + 2,000Wh storage
Daily harvest: 2,400-3,600Wh (4-6 sun hours)
Sustainable indefinitely with good sun

Hybrid approach (recommended):
Solar for daily needs (lights, phones, small appliances)
Generator for high-demand (well pump, power tools, extended cloudy periods)
20-30 gallons fuel covers backup needs

Food at 30 Days: Beyond Calories
A month of eating from storage tests more than your supplies—it tests variety, nutrition, and morale:
- Palate fatigue: The same foods get old fast. Build variety with different canned goods, seasonings, and comfort foods.
- Nutrition gaps: Shelf-stable foods may lack certain vitamins. Multivitamins provide insurance.
- Comfort matters: Coffee, chocolate, and treats aren't frivolous—they maintain morale during extended situations.
- Cooking capability: Hot, prepared meals make a massive difference versus cold canned food.

Building Toward 30 Days
Most people build to 30-day capability incrementally:
- Phase 1: Achieve solid 7-day preparedness (most achievable quickly)
- Phase 2: Extend to 14 days, add power generation capability
- Phase 3: Build to 30 days, invest in solar, develop production systems
- Phase 4: Optimize, rotate, maintain, and practice
This might take 6-12 months of gradual building. That's fine. Preparedness is a practice, not a purchase.
