General
The Department of Energy's (DOE) Energy Efficiency and Renewable Energy (EERE) website offers information on energy efficiency and individual renewable energy technologies. It provides both practical and technical information in an easy to read format.
The EPA’s Energy Star website is a comprehensive resource containing general information, guidelines for energy management programs, the Portfolio Manager benchmarking tool, and much more. The Tools and Resources section under the Building & Plants tab is particularly helpful.
The DOE's Industrial Technologies Program Best Practices site offers insights into the most common industrial efficiency opportunities, information on federal technical assistance programs (such as Save Energy Now), software tools (such as the Quick Plant Energy Profiler (PEP), MotorMaster, and the Pump System Assessment Tool (PSAT)) and other resources.
The National Renewable Energy Laboratory (NREL) provides information about renewable technologies and a glimpse into the research currently underway.
Building Operator Certification (BOC), is a nationally recognized, competency-based training and certification program that offers facilities personnel the skills and knowledge to transform workplaces to be more comfortable, energy efficient and environmentally friendly.
DOE Wind Resources Maps provide information about regional and national wind energy data and trends.
The Federal Energy Management Program (FEMP) includes a range of relevant publications and other resources. This link connects to tools for estimating energy use and the cost effectiveness of renewable technologies.
