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

Create performance measurement parameters

Implement projects to reduce utility operating costs

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
