The line graph illustrates consumption of energy between from
1980 and 2030 in USA. Overall, petrol and oil, coal, nuclear and solar/wind experienced
an upward trend. However, petrol and oil, coal increased rapily, nuclear and
solar/wind showed slightly increase.
Petrol and oil experienced both a rise and a fall from at the
beginning to 1995. Since then, the graph saw steadily increase. At the
beginning of period, when it comes to the second largest group, showed both a
gradual increase and a decrease. In the case of third largest group, the line
graph grew steadily.
In 1980, there are the same figure of three graph. But, at
the end, the numeber of nuclear and solar/wind higher than at the beginning of
period while the number of hydropower less than at the beginning of period. To be
specific, nuclear and solar/wind rose slightly, and hydropower experienced both
grow and a decline to 2015 and then remained steady.
