The given pie charts give information about energy production in a country in two different years.
Overall, it is clear that producing energy from gas showed by far the largest percentage; the reverse was true about the category called “others.” While all categories witnessed a slight rise, the proportion of petro in energy production decreased dramatically.
In 1995, the percentages of using gas, coal, and petro in energy production were approximately the same: 29.63%, 29.80%, and 29.27%, respectively. The proportion of using nuclear power for producing energy saw 6.40% compared to a mere 4.90% in the rate of the category called “others” in production.
During the decade, the percentage of using gas and coal underwent a negligible increase, rising approximately by 1%. However, the rate of using nuclear power as well as “others” was more noticeable, going up from 6.40% and 4.90% to 10.10% and 9.10%, respectively. In contrast, the proportion of using petro for making energy declined significantly, reaching 19.55%.
