consumption of energy in the USA

Question

The graph below gives information from a 2008 report about consumption of energy in the USA since 1980 with projections until 2030.

Summarise the information by selecting and reporting the main features, and making comparisons where relevant.

Sample Answer

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 in to the future. Nuclear and renewable energy sources have represented a small but significant proportion of total energy use and despite small projected gains; it is projected that they will 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 the 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
