The line graph illustrates information about the amount of electricity produced in the USA from four different sources (Coal, Nuclear power, Natural gas, and Water power) from December 2007 to November 2008.
It is apparent from the information supplied that Coal was merely higher in terawatt hours from other 3. While Nuclear power and Natural gas indicated comparison with each others gradually. Although, Water power went through minor fluctuations, even so their amount stay the same as beginning period. If we look at all sources’ increased prior to decreased and saw significantly soar before drop again.
If we look at both the highest and lowest, all sources were substantially higher than those of sources and after a month it reached approximately 370 (TWHs). Previous decreased from 370 to 300 by April 2008. While the amount of all sources increased steadily from April to June, peaking 400 (TWHs) in July 2008.Then it decreased stepply.The last three months remained stable at around 310. Coal was also a fluctuation trend followed by decreased to 150 and in March 2008 which this was the lowest amount in this trend. Starting at 150, the quantity of Coal rose dramatically, reaching 190 by July.Even so, this figure decreased and maintained the same quantity to 150. While the Water power fluctuated throughout the period given, and the figure observed the highest 25 and the lowest 20 at the end of period.
When it comes to other two trends, Nuclear power and Natural gas were competitive with each others at the beginning of period in the first 6 months. Surprisingly next 3 months Natural gas overtook Nuclear power from 100 and natural gas decreased and indicate the same percentage with Nuclear power at 100 by November 2008.
