We are building a home in western Iowa and want to incorporate renewable energy, but the financial analysis has been all bad news. System prices have skyrocketed since the 30% tax credit came about (ironic, I know), and based on sun and wind data for the area no system we have priced could even come close to paying for itself over its entire lifespan. No, it's not all about the money, but when we take into account the materials and energy to produce and install a wind or solar system, and subsequent disposal/recycling, it begins to look like we're not really reducing our eco-footprint all that much.

I would love to see links to case studies anyone has encountered, or recommendations on system configurations that have been productive in the Iowa/Nebraska/Kansas/Missouri area. We are logging our progress at http://logangreenhome.blogspot.com

You should look into leasing your solar system to avoid the otherwise decade+ long required break even point that exists in some states such as TX.  Other states, such as NJ, FL and CA are more friendly toward handing out money to solar system owners (at the expense of others), making investment into renewable energy not only a good thing to do but also cost effective.

In my case I'm a success case for my solar system even being in TX (Dallas).  By leasing the system, I'm cash flow positive from the 1st day.  And, now that my system's been running a few months, it looks like I'll be cash positive about $20 / month, taking into account lease payments.  You can get the details on the dollars flow at my web site, http://www.neukranz.com .
