Below, select the percentage score of how well prepared, or self-reliant, you are for each category. For example, if you rely completely on rain and tank water, you are 100% self-reliant in your water usage, but if you rely completely on water supplied by your council you are 0% self-reliant.
If you have neighbours to trade with, water in exchange for food, you might rate yourself higher. But if your solar system is connected to the grid and only functions when connected, you will have to think about rating yourself lower.
