The resource energy must be distinguished between renewable and non-renewable energies. In the context of IWM the focus of attentio is towards the renewable energies:
Most common is the focus on solar, biomass, and water, becaus
here decentralised and simple operating devices are available. It is als
possible to directly influence the availability and sustainable utilisation o
Non‐renewable energies require in general centralised systems o
the devices are independent of any topics from IWM (such as e.g. cars).
