Perfluorocarbons (PFCs) are primarily used in various industrial applications, including refrigeration, semiconductor manufacturing, and as solvents. They serve as potent greenhouse gases but are also utilized for their unique chemical properties. The discussion briefly touches on Power Factor Correction, clarifying that PFC in this context refers to power factor, not perfluorocarbons. Additionally, it notes that many non-industrial customers typically do not incur charges for reactive power unless their power factor is significantly low. Understanding the distinction between these uses is essential for accurate communication in technical discussions.
