I briefly touched on this in the water heater thread, but i wanted to make sure my frugal friends here are aware of these tax breaks that are good through the end of 2007. Link at http://www.energy.gov/taxbreaks.htm
The best one looks like the water heater one, because its a $300 credit on an item that i'm told doesnt cost much more (if not at all) than $300 dollars anyway (for a typical 40/50 gallon water heater). So, if you install it yourself, its basically free. The other credits might be useful too. Refer to that link above to make sure whatever you get meets the minimum specifications required to be eligible for the credit.
Remember, credits subtract directly off of what you owe on your taxes, as opposed to deductions, which you have to itemizie and dont even help unless you exceed the standard deduction.
