How to reference this medium
The energy stored in primary energy sources cannot be used directly for most applications, which is why it needs to be converted into other forms of energy. The term “energy utilization chain" describes the entire conversion process. This information module can be used to interactively visualize possible energy utilization chains. “Building heating" will be used as an example to show that losses occur during each conversion stage. This module provides detailed information for the individual conversion stages for a fuel cell.
Information and ideas:
Does energy always have to be generated across several stages? Students can research examples of opportunities for direct use and think about whether “lost" energy could be better utilized.
