First off,, if by your name you live in the Cincinnati region, wind power won't be too effective, unless you have a great site! I do imagine that your average wind speeds would be to low to make any endeavor worthwhile.
Designing an effective system for your area will entail finding out the area's average wind speeds, (you can google them) and also looking at other forms of power like PV solar panels if you have a good unshaded area to install them. A battery bank may be effective for short term outages, although some grid tie inverters actually use grid power to keep them charged. So maybe a separate, non-grid connected backup system may be worthwhile too.
It all boils down to how much you're willing to invest in your system and what resources you have available at your site.
You will probably never see "free power" just pre-paid electricity.. i would look into the current local regulations regarding what would need to be installed, and also if there are any extras to doing so, like an extra meter cost monthly.
