The graph below gives information from a 2008 report about energy consumption in the USA since 1980, with projections until 2030. Summarise the information by selecting and reporting the main features and making comparisons where relevant.

The line graph illustrates how much

energy

was generated by 6 types of fuel in the USA during a period of 44 years commencing from 1980 to 2024,

as well as

providing an estimation for the generation of

energy

until 2030.

Overall

, despite the significant growth in green

energy

, the main source remains fossil

energy

, supported mainly by petrol and oil.

Firstly

,

according to

the graph, the generation of

energy

from petrol and oil has risen steadily since 1980. At that time it was at a level of 35

quadrillion

units

and

then

rose gradually until the year 2023 when the usage was roughly 43

quadrillion

units

. It is still increasing and has been growing more rapidly since 2023. The consumption amount of petrol and oil is predicted to rise

further

and it is projected that it will reach just under 50

quadrillion

units

by 2030.

Moreover

, the usage of coal and natural gas show similar patterns and they are likely to reach approximately 30 and 25

quadrillion

units

by 2030, respectively.

Secondly

, shifting to the consumption of renewable

energy

sources including nuclear

energy

, solar/wind

energy

, along hydropower

energy

, we can see that they followed a very slight upward trend since 1980. As can be seen, they began at a level 4

quadrillion

units

and

then

increased marginally until 2010. After they remaind stabilised until 2024, it is projected to increase again by 2030.
