Resource Simulator – a Tool for Scenario Studies on Limited Resources


  • Erik Dahlquist



resources, simulation, predictions


In this paper, global resources have been gathered from different sources. From these resources scenarios have been made to get an overview of what resources will last at the present annual usage, as well as if we assume all individual would utilize the same amount or the difference between regions and populations. The most critical metal is according to this Zn, while also Cu, U, Co and Mn are relatively limited with reserves lasting in the range of 100 years. Some elements like P is not limited as such, but there is always a trade-off between total amount and at what concentration the extraction is made. For biomass and food we have enough resources if used efficiently. Wind, sun and hydropower are in reality unlimited resources for electricity production. We also have huge amounts of biomass. A question is what biomass should be used for. First it can be as a building material, then for chemical production and paper/packaging and last as energy source seems reasonable.
