The given line graft compare the changes in the quadrillion units consumption of energy between the years 1980-2030 in the USA.
Overall, it can easily be seen in the line graft that, in USA, the quadrillion units of consumption energy which petrol and oil, coal, natural gas increased while nuclear and solar/wind slight increased than hydropower almost same level.
In 1980, petrol and oil used 35 quadrillion unıts, after this term it was some fluctuation from 1995.There was gradual change and rising to 42q 2012. This increase will continue 47q in 2030. Consumption of energy from coal and natural gas has almost similar changes. In 1980, from coal 17q continue gradually change from2012. After that it will increase almost doubled 30q in 2030. Natural gas started 20q in 1980. It fluctuated between the years 1980-2012. After that, it will remain stable from 2030.
At the beginning of the period, energy from nuclear, solar and hydropower started equal to 4q. Nuclear and solar has risen slightly by 3q and 2q from 2010. Although hydropower has fallen back to 1980 almost 2q, after it was fluctuated from 2010. Nuclear, solar and hydropower remain stable last period after a years , which is 2005,2010 almost 2012.
