The chart below shows the proportion of energy produced from different sources in a country between 1985 and 2003.

The charts give detailed information about how many percentages of efficiency were produced in six different categories from 1985 to 2003.

Overall

,

it is clear that

oil production made up the largest proportion

while

other renewable resources accounted for the least share.

Moreover

, it is

also

worth mentioning that the difference between the biggest and the smallest figures was significant during

this

period. Looking at the graph in detail, the figure for toughness manufactured from oil was by far higher than that of other categories, accounting for 52% and 39% respectively in both 1985 and 2003.

Although

the proportion of Nuclear used for vitality was recorded at 22% in 1985, that of Natural gas indicated 23% in 2003, and both of them were in second place.In 1985, Natural gas and in 2003, Coal had the same share with 13% in terms of strength production. When the proportion of Coal spent on the energy industry made up nearly one in ten in 1985, that of Nuclear had more than double share in 2003.Even though the usage of other renewable resources in order to generate efficiency increased from one in hundred to nearly one in twenty, the figure for Hydrogen remained unchanged at 4% over 18 years.
