Retailers, researchers, and students of all ages often contact the Energy Savers webmaster to find out:
"Can I use your (image, diagram, or text) in my presentation?"
The answer is: yes!
All of the material on Energysavers.gov is copyright-free, and is in the public domain. That means the public - you - are welcome to use it without express permission from Energy Savers. We have made most of our diagrams available for download in low- and high-resolution so you can use them in your print and Web presentations.
Of course, you may want to cite the U.S. Department of Energy as the source, as this adds credibility to your work. Also consider adding a link to the page where you found the material.
Thanks for asking!
