- Forage and preserve seasonal fruits and vegetables.
Living off-grid sustainably takes practice. But you’ll quickly embrace the fulfilling reality of providing for yourself guided by nature’s cycles.
Choosing the Right Off-Grid Location
Selecting the ideal location is key for successfully going off-grid. Seek areas with:
- Abundant sunshine to allow reliable solar power generation. Aim for 5+ hours of sun per day.
- Available fresh water through rainfall, streams or shallow wells. Research rights and permits needed.
- Soil suitable for septic system or composting toilet. Clay is optimal for composting.
- Enough space to grow vegetables and raise small livestock if desired. 1-5 acres is recommended.
- Progressive building codes friendly to off-grid DIY construction. Seek minimal red tape.
- Ability to meet local zoning requirements for full-time occupancy. Some limit off-grid homes.
- Some tree coverage for shading to keep home cool but avoid too much shade blocking solar exposure.
