The pie charts depict the percantage of energy obtained from various power plants in a country from 1985 to 2003.Overall, the ratio of oil that was utilized for energy consumption, took place first place over this period, even though the rate of oil declined.
The percantage of oil had half of the proportion of energy produced as a 52 per cent in 1985. However that percentage decrased to 39 per cent by 2003. Besides, Nuclear power went down as a ration from 22 per cent to 17 per cent approximately two decades. Unlike the nuclear power, the percantage of natural gas peaked 23 percent by 2013 and it took place second highest energy resouces in this country.
Briefly, we can see that the ratio o f other renewable recources increased from one per cent to four per cent in this period, but it has lowest ranking with the hydrogen that has no change a a ratio until 2003. The proportion of coal climbed 13 per cent from 1985 to 2003 and stayed stable fourth place in this country.
