The Earth Day Network, which includes more than 5,000 groups in 184 countries, suggests people take these steps to help make a difference in the environment:

Audit your home energy use. A guide from the U.S. Department of Energy can be found online at www.homeenergysaver.lbl.gov/.

Check the settings. The refrigerator should be set between 38 and 42 degrees Fahrenheit, and the freezer should be between should be 0 and 5 degrees. The water heater should be on the low setting, at about 120 degrees Fahrenheit.

Try different ways of getting around. Officials encourage carpooling, riding bikes or taking public transportation.

Use less paper at home and work. Many neighborhoods and offices also have recycling programs.

Dispose of paints, solvents, pesticides, household cleaners and other chemicals properly. If not, they can get into the ground and enter the water supply.

Look for the energy star. The label, awarded by the federal Environmental Protection Agency and Energy Department, is put on products that are leaders in energy efficiency.
