Both pie charts illustrates the energy sources of a certain country and the percentages of their productions.
In the graph of 1985, other reneweable energies production has the least percentages. The natural gas and coal performances numbers are relatively similar in this year. The oil energy performance is more than the multiple of the every other energy production, during the year 1985.
In 2003, the graph demonstrates natural gas percentages is higher than coal production performances. The percentages of coal and nuclear energy productions are almost share performances in 2003. The other renewable and nuclear energy percentages share the same performance in 2003.
In 2003, the overall divisions of energy sources are better than 1985. In the pie chart, the numbers of coal and other renewable energies held in 1985 increased in the year 2003. The oil production performances in 2003 decreased compared to the 1985. However, there is percentegas that stayed steady in both years examination is the hydrogen’s.
