  • Pressure cook, batch cook, and leverage a slow cooker to conserve energy.

Stay Warm

  • Dress in layers and use hot water bottles as portable heat sources.
  • Cook, run appliances, and shower during the warmer part of the day.
  • Let sunlight heat your home naturally. Close window coverings at night.

Efficient Toilet and Water Use

  • If using a composting toilet, maintain it properly.
  • For plumbed toilets, reduce flushes and install a low-flow model.
  • Take navy showers. Reuse greywater for irrigation.

Grow Food

  • Consider gardening, sprouting and keeping egg-laying hens or meat rabbits for sustainable food production.
  • 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.
  • Sufficient wind resources if using wind power. Most sites have enough sun or wind, not necessarily both.

Scout areas in person to assess conditions before purchasing land for your off-grid oasis.
