The pie charts provide information about the amount of energy,which is directed from a variety of sources in a country, from 1985 to 2003.
Overall,it can be seen that a large amount of energy produced from oil souces ,while hyrogen prodeced less energy and remaines the same for a given time.
Initially,in 1985,oil resourse have reached 52 % in terms of energy production ong the other 5 resources.By 2003,this extent again made up large piece of the pie .Moreover,in 1985, nuclear took 2nd place in terms of energy production and accounted for 22 percent .By 2003,the some source decreased to 17% and fall to the third place .During this period,natural gas’s power generation potential incteased (from 13% to 23%)and by 2003,it had replaced neclear.
Furthermore ,it is easy to see that the energy produced from other sources was very small and amounted to berely 1 percent and 4 percent between 1985 and 2003 respectively.In 1985,hydrogen produced energy two-found low than coal,which is merely had 4 %.By 2003,coal increased in terms of producing energy during the given period of time from 8% to 13%.
