The given pie charts illustrate the changes and differences in the percentages of energy provided by five different elements in a country in 1995 and 2003. Overall, what stands out from the graph is that there were upward trends in most fields, except for nuclear that bucked the trend.
In particular, when it comes to nuclear, the graph witnessed a sharp decrease of 20% in the percentage of energy from 59% in 1985 to 39% in 2003, which accounted for the highest scores over the period.
In stark contrast, in terms of other sources of energy, the proportion stood at 3% in 1985, then increased slightly to 4% in 2003, which constantly constituted the smallest percentages. Concerning Hydrogen, a double growth from 7% in 1985 to 14% in 2003 was experienced in this figure. Besides, regarding coal and oil, the percentages of energy were at 5%, 23% respectively before rising to 32% for the former and 31% for the later.
