In addition to the usual concerns about water and power when going off-grid, this guide probes into the lifestyle changes one needs to prepare for. From a place of passion and awareness, Johnny breaks down an extremely broad subject into smaller more manageable chapters that are clearly explained, and alternative options are given. I learned a great deal about the largest water and power consumers in our modern lifestyles while also contemplating prevention and creative solutions. This guide goes from the details of how to preserve food right through to what one must have in their first aid kit and how to make a living off-grid. Although the content was in parts concerning resources in the US, there is much to be learned through listening to this thought-provoking guide. I highly recommend this audiobook and wish Johnny, Heather and their three kids the best in their adventures off-grid.
