Making your home more energy efficient qualifies you for a tax credit equal to 30 percent of what you spend and may no longer be limited as it was last year. Solar water heating, solar electric, geothermal heat and wind turbines are just some of the alternative fuel sources that qualify – even if installed on summer homes or rentals. There is no cap.

There are also credits available for energy-saving home improvements. The old 10 percent credit has now been boosted to 30 percent for 2009 and 2010 up to a maximum of $1,500 in the two-year period. Home improvements that qualify include skylights, windows, doors, biomass stoves and high-efficiency furnaces and air conditioners. The credit must be for the taxpayer’s principal residence and you must show all the appropriate documentation.

Installation costs are covered in regards to solar panels, wind energy, water heaters and biomass stoves but are not covered with windows, doors, roofs or insulation.

Credits are also available to individuals who purchase energy efficient vehicles. These tax credits are based on the weight of the car and fuel economy compared with base-year models. For hybrid vehicles for personal use, fill out IRS Form 8910 and for business purposes use form 3800. Check with your tax adviser to see if you qualify for any of these credits.    By Barry Armstrong (Money Matters)
