You can see from these lists that we are already getting a very big collection of materials and energy sources, and we haven't even started on the resources involved in manufacturing the products.
On top of that, there are resources used in organising these activities, carrying out business transactions, and transporting the products from one stage to the next.
But staying with our on-site installation, let's trace each of the items needed for this project back to the basic resources that came from the natural environment.
