My report:

The line graph shows the amount of six types of energy consumed by people in the USA over a period from 1980 to 2008 and a predicted period from 2008 to 2030.

From the graph, in 1980 the consumption of petrol and oil was the highest with 35 quadrillion units. After fluctuating for about 30 years, it rose gradually from the middle of the 1990s to 2008 and is likely to continue to increase until 2030, reaching nearly 50 at the end of that decade.

During the same period, the amount of natural gas has been fluctuating. The fluctuation is predicted to continue before the consumption levels off in the 2010s. As far as coal is concerned, its expenditure generally has been going up gradually and is not supposed to stop before 2030.

In term of renewable and nuclear energy, whereas the use of nuclear power and solar/wind power increases slightly in the considered period, that of hydropower went up and down and is likely to remain static at approximately 2 quadrillion units in the last 4 decades.

Overall, although the expenditure of energy produced from all sources increases over time, there has still been a long time before the consumption of sustainable and nuclear energy reaches the same level of that of fossil fuel.

The line graph shows the amount of six types of energy consumed by people in the USA over a period from 1980 to 2008 and a predicted period predictions from 2008 (Where did you see this year? There is no special indication on the X-axis.) to 2030. (Incomplete. What are the six types of energy? What are the units of measure? There is no rule that you have to put all the information in one sentence. Paragraphs usually have more than one sentence.)


Model:

The line graph plots the consumption of energy by fuel type by Americans in the past (1980-present day) with a forecast to 2030. Six fuel types are shown: petroleum, coal, natural gas, nuclear, solar / wind and hydropower. The units of measure are quadrillion energy units (Qu.).


Note that I define an abbreviation for the units of measure, so I don't have to keep repeating "quadrillion units" in the body paragraphs.



From the graph, (repetitious. The reader already knows that there is a line graph. You said so in the first sentence.) In 1980 the consumption of petrol and oil was the highest (Note that this does not make any sense because you have not told the reader what the types of fuel are!) with 35 quadrillion units. After fluctuating (wrong word) for about 30 years, it rose gradually from the middle of the 1990s to 2008 and is likely to continue to increase until 2030, reaching nearly 50 at the end of that decade.

During the same period, the amount of natural gas has been fluctuating. (wrong word) The fluctuation (wrong word) is predicted to continue before the consumption levels off in the 2010s. As far as coal is concerned, its expenditure (wrong word - we do not spend coal.) generally has been going up gradually and is not supposed to stop (?? Do you mean that it will go to zero? ) before 2030.

In term of renewable and nuclear energy, whereas the use of nuclear power and solar/wind power increases slightly in the considered (wrong word) period, that of hydropower varies between 3 and 5 Qu went up and down and is likely forecast to remain constant static at approximately 2 quadrillion units in the last 4 four decades. (That is 1990-2030 - are you sure that is the time range you want?)

Overall, although the expenditure (wrong word. ) of energy produced from all sources increases over time, there has still been a long time before the consumption of sustainable and nuclear energy reaches the same level of that of fossil fuel. (That is not a correct statement. According to the graph, the use of sustainable sources never even comes close to that of fossil fuels. You said that they have the same level. )

Thank you very much! Here is my feedback:

1) I looked up the word "expenditure" in Cambridge Dictionary and one of its meaning in British English is "the act of using or spending energy, time or money" so I thought it might be suitable to replace words like "amount" or "use" for referring to the amount of energy which was used. Could you give me some words to use in this case?

2) "not supposed to stop": I meant that it would stop increasing. What can I write to express that?

3) "the last four decades": I wanted to refer to the last four decades of the prediction. What can I write instead to avoid misunderstanding?

4) How about this overview: Overall, although the use of energy produced from all sources increases over time, there has still been a huge gap between the consumption of sustainable and nuclear energy and that of fossil fuel.

5) The chart gives information from a 2008 report so I used that year.

Have a nice day!

Lê Kỳ Anh looked up the word "expenditure" in Cambridge Dictionary and one of its meaning in British English is "the act of using or spending energy, time or money" so I thought it might be suitable to replace words like "amount" or "use" for referring to the amount of energy which was used. Could you give me some words to use in this case?

Most of the time, expenditure relates to money. In the human body, we write expenditure of energy by the muscle cells. The body creates its internal energy from the foods we eat, and the cells expend that energy.

Lê Kỳ Anh2) "not supposed to stop": I meant that it would stop increasing.

The problem is the subject of the verb -

As far as coal is concerned, its usage generally has been going up gradually and (its usage) is not supposed to stop before 2030.

e.g, We will not stop using it before 2030.

This is what you mean. There are many ways to express it. Here is an example:

The usage of coal is on an upward trend, and this trend is predicted to continue at a rate of 3 Qu per decade through 2030.

Lê Kỳ Anh3) "the last four decades": I

to remain constant at approximately 2 quadrillion units [ after 2010 ] / [ over the final four decades (1990-2030) ]

Lê Kỳ Anh4) How about this overview: Overall, although the use of energy produced from all sources increases over time, there has still been a huge gap between the consumption of sustainable and nuclear energy and that of fossil fuel.

Overall, although the use of energy produced from all sources increases over time, fossil fuels will continue to contribute the bulk of the energy supply. The large gap between the total of fossil fuels (Petrol, coal and natural gas) and other fuels (nuclear, solar, wind and hydropower) will remain at about a factor of six.

1980: 35 + 20 + 15 = 70 (fossil fuels); 12 for the others (divide the two; it is about 6)

2030: 101 (fossil fuels) and 17 for others

OK!



Oh, thanks a lot!

Dear expert,

Can you help review my answer?

Many thanks in advance.


The graph provided illustrates the utilization of energy in the USA over 50-year period from 1980 with prediction until 2030. It can be seen that petrol and oil are by far the most important energy over the research period. While petrol and oil, coal and natural gas consumption witnesses and are projected dramatically increase, other energy such as nuclear solar/wind and Hydropower are less likely preferred by users and predicted to be increased gradually until 2030.


In 1980, 35 quadrillion units of petrol and oil were used and became the highest consumed energy. At the same time, while natural gas stood at 20 quadrillion units and became the second preferable energy, coal is approximately 4 quadrillion units lower than natural gas. By contrast, there were approximately 4 quadrillion units in other group of energy. During the period from 1980 to 2005, while most of the energy experienced increases in the amount of energy consumed, Solar/Wind and Hydropower had small fluctuations around 4 quadrillion units.


In the next 25 year period from 2005 - 2030, following the rising trend of prior years, petrol and oil still has been by far highest consumption compared to the others and are projected to reach to a peak at approximately 47 quadrillion units in 2030. In the meantime, coal overtook natural gas in terms of usage volume and is predicted to become the second most preferable energy at around 30 quadrillion units. Additionally, the consumptions of nuclear and natural energy from solar/wind are predicted to climb up to 5 and 6 quadrillion units respectively. Meanwhile, hydropower consumption in 2030 won’t increase and just stand the same as that in 1980.
