Energy Conservation and Awareness
Energy Act of 2005 (EPACT 2005)
USDA DR 5500-001 June 19,2006
Reduce energy intensity by 20% by 2015 (baseline 2005)
Executive Order #13423 January 26, 2007
Reduce energy intensity by 30% by 2015 (baseline 2003)
Reduce fleet energy consumption of petroleum products by 22% by 2015 (baseline 2005)
Electronic products must meet Energy Star® and EPEAT requirements

Energy Conservation and Awareness
Why do we want to save energy?
Save money
Energy Independence--less dependency on imported energy from rogue countries and/or terrorist supporting countries.
Climate Change--Reduction of greenhouse gas emissions (CO2)
What is energy efficiency? Doing what we do, and finding ways to do it expending less energy and cost.
