1.   There are approximately 315 million people living in the U.S.  If every one of them used as much fossil fuel for these processes, how much usage would we have in the U.S. per day and per year?  

Oil usage/day   ____________      Oil usage/year ____________
Coal usage/day ___________         Coal usage/year ___________
Natural gas usage/day ___________       Natural gas usage/year ___________

 2.    Estimate the number of miles that you travel by car each year for commuting purposes.  Go back to the calculator and replace your car miles with either city bus or train/subway miles (depending upon what is available to you).  If you don’t have public transportation in your area, “pretend” you do. By how much did your fossil fuel usage change?  Would you make this change?  Why or why not?
  
  3.   It is estimated that the average home can save about 1,000 kwhr of electricity by replacing all of the incandescent light bulbs in the home with fluorescent ones.  The average cost of doing this is $200, but it yields about $80 in savings each year.  What would such a change to your fossil fuel usage?  Would you make such a change?  Why or why not?
