How do most people get that without money?

I can only speak for our small community in our neighborhood in a more or less rural area. Some landowners have more land than they can farm. We have received permission from them, which can be revoked at any time, to grow our own fruit and vegetables there if we keep the farmland in good condition in return. We have our own water sources there which is important if you live on an island like we do.

And since we have been doing this for several years, a certain routine has developed in the exchange of food and services. You scratch my back and I'll scratch yours. We don't need money for this.

We don't even pay rent at the moment (or only very rarely) because I take care of the house owners' garden in exchange when needed.

I don't know if this lifestyle is advisable. We are very happy with it at the moment. Maybe it is also something for others.

Electricity is nice too. How do you propose getting that?

We live in a very sunny region. Solar panels are extremely useful here.

Another good option (if you live in an environment where you have plenty of rain and waterstreams) could be the use of a Stream Engine.

Otherwise there are windmills, combustion engines, biogas plants and much more. Choose something that suits you and get started. 🙂
