Many states will reward you for making your home more energy efficient.

You could qualify for a rebate or tax break, whether your project is big or small.

In Florida, for example, you can qualify for up to $20,000 by installing solar panels that convert sunlight to electricity on your roof. The rebate for a less costly solar water heating system is a more modest $500.

If you live in New Jersey and replace your old washing machine with a new one from the state's list of energy-efficient washers, you'll qualify for a $50 to $75 rebate.

In Arizona, you could get up to $400 back for upgrading your air conditioning units.

Just about anything you can do to make your home more energy efficient makes a lot of sense right now.
