Band 6+: 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 displays the data projection for 2030 about particular energy sources (measured in quadrillion units) in The USA, with the historical year between 1980 and 2008.

Overall, throughout the period, Petrol and Oil stood as the highest number, while Hydropower remained relatively unchanged as the lowest amount of material used.

In the first year, there were three materials (Nuclear, Solar/Wind and Hydropower) that stood at less than 5. Nuclear was growing slightly to reach almost 10 in 2005. Moreover, it stayed constant and was estimated for 2030 to hit its peak. On other hand, Solar/Wind and Hydropower was oscillating from 1990 until two decades later. Solar/Wind was not changed between 2010 and 2025 and was forecasted to reach a peak 5 years later. Next, Hydropower was maintained at the same level from 2010 to 2030.

Petrol and Oil consumption was originally 35, reaching the deepest point (less 35) in 1985. next, fluctuated for one decade and rising up dramatically about 10 over the period.

In addition, Coal and Natural Gas were started at different levels. The former started nearly from 15 then fluctuated from the beginning of the year to 2015. After 25 years, it is expected to remain constant at nearly 25 quadralion units until 2030. In contrast, the latter began at 20 then climbed up gradually until reaching the highest point (almost 30) in 2030.
