UK Fuel Production Levels (1981–2000)

1\. Giải thích đề

Biểu đồ đường thể hiện mức sản xuất năng lượng tại UK từ 3 nguồn: coal, natural gas, petroleum trong giai đoạn 1981–2000 (đơn vị: energy units).

→ Dạng: line graph (time \+ comparison)

2\. Introduction (paraphrase)

The line graph illustrates the levels of fuel production in the UK from coal, natural gas and petroleum between 1981 and 2000\.

3\. Overview (ý chính)

Petroleum luôn cao nhất, dù có biến động
Natural gas tăng mạnh và vượt coal vào cuối kỳ
Coal giảm dần đáng kể
Xu hướng chung: chuyển dịch từ coal sang gas

4\. Cách chia BODY

→ Chia theo tăng vs giảm \+ dominant source

BODY 1 – Petroleum

bắt đầu khoảng \~90 (1981)
tăng mạnh lên \~140 (1986)
giảm xuống \~90 (1991)
sau đó tăng lại và ổn định ở \~140 (1996–2000)

→ Key idea:

luôn cao nhất, nhưng có biến động rõ

BODY 2 – Natural gas & Coal

Natural gas:

→ tăng đều từ \~38 lên \~100

→ tăng mạnh nhất giai đoạn sau 1991

Coal:

→ giảm từ \~80 xuống \~35

→ giảm liên tục, chỉ tăng nhẹ giai đoạn giữa

→ Key idea:

gas tăng mạnh và vượt coal, trong khi coal suy giảm rõ rệt

Ví dụ câu:

Petroleum remained the dominant fuel despite fluctuations.
Natural gas rose steadily and eventually overtook coal.
Coal production declined significantly over the period.

The line graph shows changes in UK fuel production levels from 1981 to 2000, measured in energy units, for coal, natural gas and petroleum.

Overall, petroleum remained the dominant source throughout the period despite some fluctuations. Natural gas experienced a steady and then rapid increase, while coal production declined consistently over time.

In 1981, coal and petroleum were the main fuels, at about 80 and 85 energy units respectively, whereas natural gas was much lower at around 37 units. Petroleum production rose sharply to approximately 140 units in 1986 before falling to about 90 in 1991\. It then recovered, reaching around 140 units again in 1996 and remaining stable at this level in 2000\.

Coal production followed the opposite trend. After starting at roughly 80 units in 1981, it dropped significantly to just under 50 in 1983, recovered slightly to around 60 in 1986, and then declined steadily to about 35 units by 2000\.

Natural gas showed continuous growth. It increased gradually from about 37 units in 1981 to 42 in 1991, before rising more sharply to nearly 80 units in 1996 and finishing at approximately 100 units in 2000\.
