The given pie charts reveal the way in which energy produced from variety of sources changed in a nation from 1985 to 2003.
Overall, the highest percentage of both pie charts indicates that oil was the most produced energy over that period of time. Moreover, hydrogen stayed steady with approximately the lowest production, regardless to other renewable energies which constituted the lowest one.
It is evident that oil made up 52% of energy production in 1985, whereas it is still the highest proportion in the second figure which indicates 2003, but with a bit diminish to 39%. Furthermore, nuclear produced in 1985 had 22% of all fuel productions with its remarkable ratio after oil, but it minimized to 17% in 2003. With regard to the second figure, natural gas took nuclear productions’ place and became the second most produced energy in 2003, while it had the proportion of 13 percent in the first chart. Also the production of coal increased to 13%, when it had 8% of all ratios in 1985. In addition, the trend of hydrogen produced was consistent over that period of time with 4%. Other renewable energies had a slight increment from 1985 to 2003, by 1% to 4%.
