Facilities can reduce their energy use by increasing energy efficiency in production processes, incorporating energy conservation into facility operations and design, and using more renewable or sustainable energy sources. Improved energy management can save money, abate pollution, reduce greenhouse gas emissions, and ease demand on natural resources. The Performance Track program encourages applicants and member to report on improvements in the aspect of energy use listed below. Examples of appropriate measures are also provided.

Total (non-transportation) Energy Use by fuel type |

In order to improve energy use, Performance Track members are:
- developing Energy Management Plans to increase operational efficiency
- replacing older process equipment with higher efficiency models
- upgrading lighting and heating, ventilation, and air conditioning (HVAC) systems
- increasing insulation to reduce fuel requirements
- shutting down equipment when not in use
- adjusting industrial furnaces to operate at a lower temperature in standby mode
- implementing process improvements to increase efficiency (e.g., shifting from batch production to continuous operation to reduce electricity and steam generation requirements)
- monitoring and controlling energy use throughout the facility
- conducting energy audits to identify further areas for improvement

Other examples of energy management strategies include:
- designing energy efficient buildings and equipment
- installing cogeneration systems
- using environmentally preferable energy sources (e.g., wind and solar energy)
Facilities can reduce costs through more efficient use of energy. Cost savings result from:
- reduced energy input requirements
- reduced waste treatment and disposal costs through increased process efficiency
- increased productivity and process efficiency through optimized production cycles
- reduced capital and space requirements
In many cases, facilities are able to recoup initial investments in energy efficiency in just over a year, with future energy cost savings adding directly to the bottom line.

Conversion and Contextual Factors for Energy Use
Methods to convert non-standard measurement units into standard units, and methods to convert environmental improvements into commonly understood contexts, can be found through the links below:
- Conversion factors (e.g. Btu equivalent
for a kilowatt-hour of electricity)
The State of Wisconsin Department of Administration's website provides Energy Definitions and Conversion Factors.
The Eastern Region Association of Higher Education Facilities Officers provides a tablelisting the relative Btu content of primary and secondary fuel along with the Btu content of common fuels such as coal, oil, and gas.
- Contextual factors (e.g. the average
annual household use of Btus)
The Energy Information Administration offers various energy-efficiency related reports. Within these reports, the following information is available:
- A
table
listing energy use the United States by year and by housing type.
- A
chapter
describing energy use and intensity in the industrial sector, including manufacturing and other non-manufacturing sectors not included in transportation or services.
- A website with
tables
containing information on energy use in the manufacturing industry.
Buildings represent 38.9% of U.S. primary energy use, and 70 percent of office building energy consumption is electricity used for lighting, heating, cooling, and office equipment (www.GreenBizLetter.com, April 2003).

General Resources
EPA's Energy Star Buildings & Plants offers a variety of technical resources for energy efficiency, such as operations and maintenance guides, tools for benchmarking, financial benefits of improved energy efficiency, and case studies.
EPA's Energy Star Labeled Office Equipment presents information on energy-efficient office products that save money while reducing pollution. The site also offers online brochures on energy-conserving equipment and details the savings associated with these products.
EPA's Green Power Partnership is a voluntary program that encourages organizations to buy green power as a way to reduce the environmental impacts associated with purchased electricity use. Partner organizations can receive technical support leading to the purchase of green power. By meeting or exceeding EPA's purchase requirements, Partner organizations receive valuable recognition for their actions.
Climate Leaders is an EPA industry-government partnership that works with companies to develop comprehensive climate change strategies. Partner companies commit to reducing their impact on the global environment by completing a corporate-wide inventory of their greenhouse gas emissions.
