Đề bài: The pie charts below show electricity generation by source in New Zealand and Germany in 1980 and 2010.
GERMANY NEW ZEALAND
The pie charts illustrate the units of electricity produced, divided by sources (Coal, Petroleum, Natural Gas, Nuclear, and Hydro), in New Zealand and Germany in 1980 and 2010.
Overall, there were dramatic changes in the quantity of electricity generated by different sources in both NewZealand and Germany over the period given. Whilst Coal is seen as the most common source of electricity in New Zealand in both 1980 and 2010, Germany saw a significant increase in the use of nuclear. There was also an upward trend in the number of units produced by both New Zealand and Germany over the period given.
To begin with, coal was the primary source used to produce electricity in New Zealand in 1980, which stood at 56 units, followed by hydro and natural gas, each of which accounted for 30 units. From this point, coal experienced a considerable rise to reach a peak of 150 units in 2010, considerably exceeding the units of electricity produced by the other sources. Specifically, the figure for hydro was 46, as opposed to just 2 for petroleum and natural gas. Given the significant growth in the number of units produced by coal and hydro, the total units in 2010 peaked at 200, as opposed to just 127 in 1980 in New Zealand.
As to Germany, Germany witnessed the relatively equal contributions of nuclear, natural gas, coal, and petroleum to the total units in 1980, each of which composed 20, 28, 28, and 22 units, in that order. Surprisingly, the quantity of units of electricity produced by nuclear experienced a sharp growth to reach a peak of 155 units in 2010. Whilst the number of units of electricity produced by coal remained steady over the period, the figure for petroleum saw a slight jump to 27 units in 2010. As many as 214 units were generated in 2010 in comparison to just 107 units produced in 1980 in Germany.
