An extraordinary tool for your use is E2Finance, developed in 1990s by Tellus Institute but no longer supported. It does just about every financial calculation for EE investments that you need. And its free. I have been hosting a download of it from my website for several years. http://cleanerproduction.com/misc/Finance.htm There is a more simple version of it in Excel format, P2Finance, also available. If you use it and it's useful please let me know, I am trying to collect user feedback. Its the best financial analysis tool for capital investments that no one has ever heard of. Hope its helpful, Burton Hamner Cleaner Production International LLC www.cleanerproduction.com <http://www.cleanerproduction.com/> 206-491-0945, wbhamner at cleanerproduction.com 5534 30th Ave NE, Seattle, WA 98105 Fax 206-206-339-1686 _____ From: p2tech-bounces at great-lakes.net [mailto:p2tech-bounces at great-lakes.net] On Behalf Of Kathey Ferland Sent: Wednesday, August 12, 2009 12:05 PM To: 'Vinson, Thomas'; p2wazoo at lists.preventpollution.org; p2tech at great-lakes.net Subject: Re: [p2tech] energy efficiecy payback * * * * * * * * * * * * * * * * * * * Win a free iPod and help GLIN grow!

For that, you'll need to know the project cost, which is highly site specific. Although it is called "Texas Sized Energy Savings" it can be used anywhere. http://TexasIOF.ces.utexas.edu/ under "What's New" Kathey Kathey A.
