If you have been thinking about installing a geothermal system there is no better time then right now.  With federal tax credits at 30% with no limit and rebates from Mid American you are looking at a incrediable amount of savings.  That means if you system would cost $20,000 your rebates for Mid American would be up to $3,100 and a federal tax credit of $6,000 that really cuts down on the cost.  If you are building a new home or on LP gas you are a perfect candidate and should seriously consider installing a new geothermal system.
