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.
