Energy Conservation 101

Energy Conservation 101: Energy Fundamentals, Baseline, and Benchmarking

This course, based on the WEF Manual of Practice No. 32, Energy Conservation in Water and Wastewater Treatment Facilities, provides background on energy fundamentals. The techniques and information provided are essential for properly conducting energy evaluations for specific unit processes.

The fundamentals of identifying and qualifying the energy usage and conservation opportunities at a typical WWTP are discussed. An overview is provided for identifying and ranking the most significant opportunities, establishing baseline energy usage, and benchmarking plant energy consumption. Typical utility billing is discussed, with an emphasis on electric power, time of day, and demand billing. This topic also demonstrates the difference between reducing energy consumption and reducing energy expenses. The analysis techniques of cost and savings calculations are presented with example calculations.
