Energy Uses in Connecticut

 

Student Materials

 

Energy is used everyday to heat and light our homes, schools and businesses.  Have you ever thought about where the energy we use everyday comes from?   How have these energy sources changed over the last several decades?

 

You have been provided with a spreadsheet containing some information about energy use and its sources in Connecticut from 1960 through 2001.  Use this information and the Excel program to prepare a line graph showing the trends in the energy consumption from the following sources: coal; natural gas; nuclear; hydroelectric; and wood/waste over this time span. 

 

Your task is to choose one of the fuel sources (coal, natural gas, nuclear, hydroelectric or waste) and research the advantages and disadvantages of this particular energy trend as it is illustrated on the graph.  Does this trend support Connecticut’s initiative to significantly decrease the use of non-renewable resources by the year 2010?   Some support materials for the study of energy resources may be found at the websites listed below and many others.
