Why Energy Audits Aren't Enough: An Energy Management System is Required
An evaluation of the energy systems in a plant can be accomplished by different techniques which require different levels of effort. Three alternatives are described: Rational Analysis, Energy Audits and Energy Management by Utility Systems Metering. A progressively greater investment in time and funding is required; however, the results yield more information and greater accuracy about energy usage. It is recommended that the step beyond Energy Audits, an Energy Management System, be taken. The Energy Management System approach is worthwhile, and the additional time and funding will be returned in energy cost reductions.

Energy-Efficient Dry-Type Distribution Transformers: New Opportunities to Cut Energy Bills and Lock-in Long-Term Energy Savings deLaski, A.; Suozzo, M. (Energy Systems Laboratory (http://esl.tamu.edu), 1998-04)Nearly 90% of the electricity that powers the industrial sector flows through dry-type distribution transformers. These transformers are very efficient- most convert in excess of 95% of input power to output power. However, ...
