What is a characteristic of flow resources?

Flow resources are characterized by their need to be utilized at the moment they are generated and in the location where they occur. This is due to their inherently transient nature; they cannot be stored for later use without significant loss or conversion. An example of a flow resource is solar energy, which is produced only when the sun shines and must be harnessed at that time.

Additionally, flow resources are generally renewable as they are replenished naturally. However, the fact that they must be used immediately is the defining trait that differentiates them from other types of resources. This characteristic emphasizes the importance of timing and location in resource management, distinguishing them from resources that can be stored and used at a later time, such as minerals or fossil fuels.
