## Improve energy efficiency and reduce green House gas emissions of the agency by  3% annually, or 30% by the end of FY2015, relative to the baseline of the agency’s energy use in FY2003

*****
NREL Goal: Beginning in FY2006, NREL will achieve “carbon neutrality”

- *****
_**NREL Goal:**_ Beginning in FY2006, NREL will achieve “carbon neutrality”

**Executive Order 13423 Goal**

## EPA Climate Leaders Program (CLP)

**Initial CLP Goal:** NREL pledged and met its goal to reduce its normalized (Btu/sq.ft.) GHG emissions by 10% from 2000 to 2005
**Second CLP goal:** NREL pledged to reduce its total U.S. greenhouse gas emissions by 75% from 2005 to 2009

## Slide 6

## Energy Use Reduction

-   Energy retrofits
-  Relatively new facilities (circa 1990) – limited opportunities
-  Current site-wide ESPC (DOE TEAM Initiative)
-   New construction
-  Science & Technology Facility (LEED Platinum Certified)
-  Research Support Facility (LEED Platinum and Net
-    Zero Energy (NZE))

## On-site Renewable Energy Projects

_**Power Purchase Agreement (PPA)**_
- Third party developer PV projects
- Xcel Solar*Rewards Program
- Sun Edison (developer)
_**Energy Savings Performance Contracting (ESPC) **_
- Biomass combustion heating plant
- Ameresco Select (ESCO)

- Alternative Financing Mechanisms

## Mesa Top PV Project

**Mesa Top PV Project**

## Mesa Top PV Project(Power Purchase Agreement)

-   750 kW (1,200,000 kWh) one-axis tracking
-     PV system
- Located on South Table Mountain on 5-6 acres
- Grid connected (NREL “side of the meter”)
