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

• 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
