The main types of energy audits include the walkthrough audit, utility bill analysis, and detailed energy audit.

A walkthrough audit is often the initial step in energy auditing, where an auditor visits the site to visually assess energy usage, operational practices, and energy systems. This type of audit is aimed at identifying potential areas for improvement quickly and requires relatively low investment in time and costs.

Utility bill analysis offers a quantitative approach by reviewing historical energy consumption data reflected in utility bills. This method helps to identify patterns and anomalies in energy usage which might indicate efficiency issues, thereby forming a critical part of the auditing process.

The detailed energy audit delves deeper into the analysis and typically involves comprehensive measurements and data collection on energy systems, sub-systems, and equipment. This audit stage provides detailed recommendations and often justifies specific upgrades or efficiency measures, offering a clear roadmap for energy savings.

The combination of these three types represents a thorough approach to understanding and improving energy efficiency in a facility, making option B the correct choice.
