Sample Response Five
The provided graph offers insights into the energy consumption trends in the United States starting from 1980, with predictions extending until 2030 based on a 2008 report. The data shows that the USA relies on a diverse range of energy sources rather than a single one.
To begin with, in 1980, petrol and oil stood out as the primary source of energy, with the USA consuming 35 quadrillion units, the highest among all energy sources. In contrast, nuclear, solar, wind, and hydropower combined produced less than 5 quadrillion units, making them the least utilized sources.
Despite natural gas surpassing coal in energy production in 1980, with 20 quadrillion units compared to coal’s 15 quadrillion units, there were fluctuations in the consumption of both over the years. However, the projection suggests that by 2030, coal will surpass natural gas, producing more than 25 quadrillion units.
Petrol and oil continued to be the dominant sources of energy, with their consumption gradually increasing and expected to reach over 45 quadrillion units by 2030. Meanwhile, other sources such as nuclear, wind, and solar demonstrated steady growth, but hydropower is projected to produce a smaller amount of energy in 2030 than it did initially.
Sample Response Six
The line graph provides an overview of energy consumption by different fuel types in the United States from 1980 to 2008, along with projections extending until 2030.
In summary, fossil fuels have historically dominated energy consumption and are expected to continue this trend in the future. Petrol and Oil have consistently been the largest contributors, with Natural Gas and Coal following. Nuclear and renewable energy sources have played a smaller but significant role, with projections indicating some growth.
Petrol and Oil were the leading sources in 1980, with a consumption of 35 quadrillion units (35q). By 2008, their consumption had risen to approximately 40q, and it is predicted to continue increasing, reaching nearly 50q by 2030. In 1980, Natural Gas and Coal ranked second and third, with consumption levels around 16q and 20q, respectively. Coal overtook Natural Gas in 1990, and despite some fluctuations, it is expected to remain the second most used fuel in 2030, with consumption slightly above 30q. Natural Gas, on the other hand, is projected to level off and maintain a relatively constant consumption of about 25q.
Nuclear and renewable energy sources, such as solar/wind and hydropower, each represented around 4q in 1980 and experienced fluctuations until 2008. The projections suggest that by 2030, nuclear energy will increase to 10q, while solar/wind will reach around 5q. Hydropower, however, is expected to decrease and then remain stable at approximately 2q.
