Instead of going off grid and finding things out as you learn them and then regretting not knowing them later, this video covers 10 things you can know before you go off grid. The video is from Fouch-o-matic Off Grid and they tell us the 10 things they wish they had known before going off grid.
Some of the things may seem like common sense to folks but when you are doing things for the first time ever I am sure you can be to close to the forest to see the trees. There would be many many things to think about, plan and build, fix or deal with so I am sure you may do things in a way that ,might have been done differently if you had only had that one thing to deal with. When we have a lot going on it is easy to just do what we have been doing and not have the time to think about doing something different.
After watching the video at least you will have these ideas that they learned along the way already stored n your head and will be able to draw on them to help you not start out the harder way. They spent a couple of years living in a yurt, which while sounding interesting also sounds cold to me. I think I am maybe a little old to go off the grid in a yurt.
