Energy: Efficiency, Conservation, Renewable Energy

New Approaches to Energy Generation and Usage are Crucial to Our Future

Energy solutions, both in industry and everyday living, have always been of great importance to us at EEI. Here we present reports on the issue, prepared by EEI and others.

Some of the papers provided here cover other water utility topics. Dialog on any topic is always welcome. You may comment through our Water Systems blog, or contact us by phone or email.



How do I Assess My System's Energy Efficency
A summary of the value and methods to implementing an eenergy efficien cy program Presented at the "Florida Water Resources Conference" April 2016

Adobe Reader icon   Optimizing Operational and Performance Efficiency
Summarizes the secondary value of efficiency improvements, published in Journal of Florida Engineering Society, Marych 2018

Adobe Reader icon   Energy Efficiency Paper - Fort Myers, FL (Sept. 13, 2012)
Our Don Voigt presents an Energy Efficiency paper at the Fifth Annual Southwest Florida Water and Wastewater Exposition – Sept 13, 2012, Fort Myers, Florida Convention Center. PDF of Power Point presentation.

Adobe Reader icon   Pump Analysis - Audit - for Energy Consumption - Recommended Tools
Pumps (and blowers) are a major contributor in most industrial/municipal energy consumption loads. This single sheet summary might offer reminders of the tools which have been most useful in providing insight into ways to refine the performance of these key elements in your facility. For further reading (to better understand the value of the suggested measurements), we suggest a review of how “rpm under load” can be a valuable tool and “watts vs amps” for true load profiles in 3 phase motors.

Adobe Reader icon   Administrative Workshop for Wastewater Management – Marquette, MI
Amongst the regulatory and funding agencies for our nation (EPA, DOE, WisCap, and similar), there is a consensus that the need for a basic understanding of energy audits is escalating. Recent EPA Webinars suggest that a Type II energy audit should be conducted for all community wastewater and water treatment facilities. Our chief engineer – Don Voigt, P.E., CEM – provided a summary of the need and the “mechanics” of energy audits for a group of 47 water and wastewater managers attending the UP Michigan Department of Environmental Quality Winter Managers Conference in Marquette MI on December 7, 2011. PDF of Power Point presentation with 60 plus slides.

Adobe Reader icon   Energy Audits – A First Step in Utility Cost Reduction
If you intend to improve upon any endeavor, establish a starting point or benchmark at the beginning. Particularly in the area of energy consumption, an energy audit is the best first step. In this report presented in the Florida Engineering Society's Journal on Energy, Don Voigt reviews the audit procedures and offers insight into how to benefit from a facility audit.

Adobe Reader icon   Technology and Equipment for Measuring Power Usage – UW Madison, WI November 2010
One of our principals was asked to be a guest instructor for several recent seminars with a similar theme – Managing Energy in Water and Wastewater Utilities. The following PDF file of the PowerPoint presentation is excerpted from a November 18-19, 2010 seminar sponsored by the University of Wisconsin – Madison College of Engineering, Department of Engineering Professional Development. As the title suggests, the presentation offers insight into energy consumption benchmarking through field auditing of key systems and equipment within the owner's facilities.

Adobe Reader icon   WRc Focus on Energy Benchmarking Report
Midwest USA energy consumption for water and wastewater plants benchmarked and compared to world standards for similar facilities. Demonstrates the importance of engineering for energy efficiency in public utilities.
