The charts below show the percentage of the energy generate from different resources in a country in 1985 and 2003.

The pie charts describe the proportion of how various resources generated energy in a particular nation in 1985 and 2003.

Overall

,

it is clear that

oil emerged as the most predominant commodity in the country in both years,

whereas

renewables and hydrogen were the least prevalent.

While

natural gas and coal allocations increased, nuclear declined during

this

timeline. In 1985, oil power plants accounted for 52% of total energy, which was by far the greatest allocation of any other.

Subsequently

, in almost two decades,

this

number dropped to 39%.

Although

renewables had the smallest share at the start (1%), they maintained that position in the following years,

along with

hydrogen, which remained essentially stable in both periods at 4%.

In addition

, at the beginning of the period, 13% and 8% of power were contributed by natural gas and coal, respectively, and these figures rose to 23% and 13% in 2003.

In contrast

, the percentage of nuclears' experience decreased to 17%

at the end

of the time surveyed.
