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 shows

energy

consumption by fuel type in the United States from 1980-2008, with projected use until 2030.

Overall

, fossil fuels have been the dominant type and will continue

this

trend into the future. Nuclear and renewable

energy

sources have represented a small but significant proportion of total

energy

use, and despite small projected gains, they are projected to continue doing so. Petrol and Oil command the biggest share with 35 quadrillion units (35q) in 1980, rising to approximately 40q in 2008, and

this

trend is set to continue with a projected value of nearly 50q in 2030. In 1980 natural gas and coal came in second and

third,

with around 16q and 20q, respectively.

However

, coal overtook natural gas in 1990 and, despite some fluctuation, is set to be the second most used fuel in 2030 with just over 30q. It is predicted that natural gas will level off and remain relatively constant at about 25q. Nuclear and renewable energies all represented around 4q in 1980 and fluctuated up until 2008. It is speculated that nuclear

energy

will reach 10q by 2030 and solar/wind around 5q, with hydropower dropping and

then

remaining constant at approximately 2q.
