Offgrid for 21 May: Fridge Backup Planning, Outage Cost Reality, South Wall Shading

Offgrid is a daily audio summary of the latest ideas, innovations, products, and hard-won lessons for living autonomously and becoming more self-sufficient in energy, tech, food, water, shelter, and everyday systems. This 3-story episode draws from OffGridLiving, OffGrid and moves through fridge backup planning, outage cost reality, south wall shading. 1. Fridge Backup Planning This thread turns a vague shopping question into a backup-power sizing lesson. The immediate problem is not just spoiled food, but refrigerated insulin that becomes risky once a long outage pushes the fridge temperature up.

One family tracked roughly twenty-seven hundred dollars in direct food and refrigerated medication losses across four outages, without even counting hotel costs or the fuel spent hunting for ice.

South Wall Shading This post is really about whether spare roofing metal can double as a protective skin on a cabin wall without making summer heat worse. The owner wants to shield a south-facing plywood wall from weather and ultraviolet exposure by mounting metal over it with about a one inch air gap.
