19. 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

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.
