Saving Water/Saving Energy
September 2, 2003
Water and wastewater facilities operated by U.S. business, industrial, municipal water users, and others consume 75 billion kWh of electricity annually, or about 3% of the total U.S. electricity consumption. This is equal to the total electricity consumed by the pulp, paper, and petroleum sectors combined. On a global level, the movement and treatment of water accounts for 7 percent of total energy usage.
To address this connection between water and energy usage, DOE Denver Regional Office, in conjunction with the State of Colorado Office of Energy Management and Conservation recently hosted the Saving Water/Saving Energy workshop. This event, held in Denver, Colorado on August 14, 2003, successfully brought together large commercial, industrial and municipal leaders, spanning the state of Colorado. The workshop raised awareness about the water/energy connection at a time when substantial interest is being paid to both issues.
Saving Water/Saving Energy addressed three important issues related to energy and water efficiency:
- Faced with a recent water shortage, commercial and municipal facilities in the Western region seek solutions to mitigate the impact on operations and revenues, and prepare for future water challenges. Improved efficiency during pumping, treating, heating, cooling, or conversion to steam can be part of the solution.
- By addressing water efficiency, businesses and municipalities also have the opportunity to reduce the demand for electricity, now that reliability and vulnerability are in the forefront.
- Energy efficiency improvements also free up valuable natural gas.
The event in Colorado drew nearly 200 business, municipal, and industrial participants for workshops and exhibitor demonstrations. They learned about opportunities, resources, innovative technologies, and tools available today that will simultaneously address water, electricity, and natural gas usage and improve overall resource efficiency.
DOE BestPractices hosted discussions on pumping and steam system efficiency as it applies to water and wastewater management. The event featured hands-on demonstrations of key BestPractices software tools: MotorMaster+, Pumping System Assessment Tool (PSAT), and the Steam System Assessment Tool (SSAT). These powerful self-assessment tools help plants identify opportunities for system-wide savings and improved performance.
For many attendees, this was a unique opportunity to understand the direct link between actions that save water and reduce energy demands. The event provided a venue for businesses and industries to network and discuss water and energy saving solutions.
Saving Water/Saving Energy was designed as a model for similar events that could be held throughout the nation. Energy efficiency and reliability issues can be addressed in reference to other related local priorities and issues. For more information on other events contact the DOE Regional Office in your area.
