the charts below show the proportion of the energy produced from different sources in a country between 1985 and 2003 summarize the information by selecting and reporting the main features and make comparisons where relevant

The given pie charts provide statistical data about the percentage of

energy

production from various derivations in an unspecified nation in 1985 and 2003.

Overall

, at the beginning of the period, the other renewable segment contributed the least to

energy

production, whilst oil was the most significant sector. In comparison,

at the end

of the period, oil still dominated the biggest contribution to the

energy

manufacturing of a country

while

some of the other segments witnessed an increase. In 1985, oil accounted for over half of the

energy

in an unknown country, 52% before plummeting to only 39%. The power production from the nuclear sector was at 22% and had a dramatic decline of 5%. Meanwhile, the contribution from hydrogen remained constant at 4%. At the beginning of the period, the other renewable and natural gas sources made up 1% and 13%, respectively and both witnessed an escalation of up to 4% from other renewables and nearly a quarter from natural gas. Coal comprised only 8% and it

subsequently

experienced almost a twofold rise in 2003, 13%
