Recession or not, this might be the year to make some home improvements. Federal tax credits for energy-efficient home improvement had lapsed in 2008, but were reinstated for 2009.

This means that if you install insulation, replace windows, get a new water heater or certain kinds of HVAC systems, you can claim a cumulative credit of up to $500.

Your new, more efficient appliances will also save you money by using less energy, so you can compound your budget benefits!

For example, if you install a Rheem Tankless Water Heater (they sent me the press release about the tax credits, so they get a shout out), you will earn a credit of up to $300. On top of that, you will use an estimated 30% less energy.

Plus, it's so eco-cool and streamlined to have a tankless water heater -- have you seen one in action? They give you endless hot water with seriously reduced guilt.

Well, reduced, not eradicated, you should still be responsible about your water use. But it's nice to know you'll always have enough hot water to rinse out a head full of shampoo, regardless of how many people took a shower ahead of you.

I am totally installing one in my all-bamboo green dream house, along with a very sophisticated grey water system and mad solar panels ... if only I had the money to build it this year to take advantage of the tax credits!
