The line graph shows the record and expectation about consumption of energy from 1980 to 2030 in America.
It is obvious that consumption of petrol
and oil has been remained the most and it is expected that it will remain
position continuously in the future. Coal and natural gas has been similar but
coal will be surpass natural gas from 2015.
Looking at the figure closely, there was
fluctuation to patrol and oil from 1980 to 1995. However, it has been gradually
increased since 1995 and also it will experience the upward trend until 2030.
Even though coal has been gone up and maintained repeatedly from 1980 to 2015,
it is speculated that it will increase rapidly from 2015 to 2030 peaking at about 30 quadrillion Natural gas
has been fluctuated from 1980 to 2015 and it will remain until 2030 at under 25 quadrillion. Nuclear
and solar/wind and hydropower were under 10 quadrillion units and it will not be
changed afterward.
