CHICAGO - Consumers are bombarded these days with a multitude of suggestions to make their lives "greener." For many of them, changes start at home.

That's not a bad idea: The government estimates that the energy Americans use just to run their homes makes up 21 percent of total energy use throughout the country. And that statistic doesn't even touch on the other environmental issues that can be addressed in a home, including water conservation and indoor air quality.

1. Washers that save energy and water

2. Toilets that conserve water

3. No-VOC paints

4. Smart thermostat applications

5. Low-flow faucets and showerheads
