Energy Conservation
Established Best Practices database (BP) by system and geographical location
Developed training and measurement parameters to reduce utility consumption without spending capital
Set and enumerated goals (4.5% total savings in 2004 and 2005)
Change mindsets
ENERGY INVESTMENTS
9
Energy Investments
Evaluate energy investment projects
Analyze projects for energy cost savings and return

What Can You Do?
Create effective and realistic energy efficiency building codes
Provide direct and indirect (through the utilities) energy efficiency incentives
Lobby for competitive access that will promote energy efficiency in the generation sector
Lobby for and require fair interconnection standards and rate structures that will promote CHP and the associated energy and environmental benefits
