DOWNLOAD EBOOKAccording to the U.S. Department of Energy, 45% of a typical home utility bill is for heating and/or cooling. We may not have any control over how fuel efficient our home was constructed, but we can control the setting on the thermostat. Consumer Reports suggests that every 1° change in our thermostat setting has a 2% impact on our utility bill. Consider the story of Maria and Josef. In parts of the United States where the climate turns cold during the winter, many homes are heated by oil. Mark lives just outside of Boston in a house heated by oil. During the winter of 2007, Marks paid $2.95 per gallon for home heating oil. The price of home heating oil has since increased to $4.45 per gallon. Looking ahead to the winter of 2008, Mark wants to budget enough money for his oil bills.
