  16. 16. STATE-OF-THE-STATE 10/08 Minnesota Ranks Fourth In Installed Capacity 1377  MW Installed From 1155 Utility-scale Units (21,017 MW Installed In The U.S.) Who Are #1, #2, and #3? Who Are #5 and #6?  GE, Enron, Zond, Vestas, Suzlon, Kenetech, NEC  Micon, Siemens, Gamesa and Nordex. Generator Capacities = .66 MW to 2.5 MW  MN Production Now = 4.2 billion kWh  Minnesota Ranks Ninth In Potential = 230 billion  kWh with 75,000 MW Installed @ 35%LF Who Is #1 In Potential?  By 2020, 6% Of U.S. Electricity From Wind  Go To www.awea.org and Click On Resources and  Scroll To Projects (US) For More Info
  17. 17. Photovoltaic System (PV) >Sanyo 4.68 kW array (24 panel) >240 sq ft @ 23 degrees >$10/watt installed ($10,000/kW) >State rebate = $10,530 >Utility rebate = $4,000 >Federal tax credit = $2,000 >Output = 6,000 kWh/yr ($550) >Simple payback w rebates = 40yr (@ $.15/kWh av rate = 24 yrs)
  18. 18. Photovoltaics About To Emerge Innovalight = Thin film flexible @ $1/watt  (print cells on metal foil with ink saturated with silicon) available in 2009! Nanosolar = Thin film made of CIGS @ $1  /watt (copper, indium, gallium and selenium) available now! Energy Innovations = use conventional high  quality crystalline solar cells with magnifiers. One cell yields output equivalent to 800 cells. Result = whole-house system @ $4,000 (could  be roof covering

  23. 23. Project Conserve Community-wide Project Designed To Instill A Sense  Of Responsibility To Conserve Resources. Target Resources: Electricity, Gas, Water, Garbage,  and Transportation Fuels. First Year Pilot will identify potential savings with 30  participants – begins Oct 08. Includes: Collect participant historical use data  Home visits with blower door/infrared scans  Participant info & success sharing workshops  Monthly newsletters to participants  Quarterly Project updates in local media  Project update at 2009 Energy Expo  First year culminates with offer to Elk River Community  to do likewise.
  24. 24. Project Conserve Goals Reduce Electrical Use in 5 years by 20% Reduce Gas Use in 5 years by 10% Reduce Water Use in 5 years by 25% Reduce Solid Waste Stream in 5 years by 25%
  25. 25. Projected Outcomes Save the participants $$ and see changes in  their habits Expand to entire city  Be a model for other communities 
