The four pie charts on the previous page come from an Environmental Protection Agency document titled
Sector Collaborative on Energy Efficiency Accomplishments and Next Steps: a Resource of the National Action plan for
Energy Efficiency (July 2008). The charts illustrate how U.S. hotels consume energy. It is important to note that
the largest user of electricity is lighting and the largest user of natural gas is water heating. These following
suggestions can help you cut costs by implementing energy-efficient options for your hotel.
