Final answer:
The highest-scoring category for alternative energy is based on frequency of non-compliance, indicating the difficulty of meeting frequency-based requirements. The lowest-scoring category relates to structural requirements, highlighting the challenges associated with building components in energy production.
Step-by-step explanation:
The category with the highest score is Category C, which is based on the frequency of non-compliance. This indicates that alternative energy is not easy to implement in terms of meeting frequency-based requirements. For example, if a hospital has a high number of incidents where it is found not to be compliant with alternative energy standards, it will receive a lower score in this category.
The category with the lowest score is Category A, which indicates structural requirements. This suggests that the attribute hardest to satisfy in energy production is related to structural components, such as building components. Meeting these requirements may involve significant investment and technical expertise.
