The pie charts indicate changes in the proportions of energy produced in a country from 1983 to 2003. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

The pie charts illustrate modifications in the figures for

energy

produced in a country between 1983 and 2003.

Overall

,

it is clear that

the proportions of

oil

and coal

energy

produced decreased significantly

while

the figures for nuclear power and natural gas

energy

increased and the proportion of hydropower

energy

produced was the same over the period shown. Remarkably,

oil

energy

produced accounted for far by the highest proportion of the total. Looking at the information in more detail, we can see that the highest proportion of

energy

produced in a country in 1983 was

oil

, with 43%, the second highest was coal, with about a quarter of the total ( 23%), followed by nuclear power, with 20%,

finally

, natural gas and hydropower, with 11% and 4%, respectively. In 2003, despite decreasing to 38%,

oil

energy

still situated at the top of the total, after growing to 24%, nuclear power is close second to

oil

, followed by natural gas and coal, with 21% and 13%, respectively.

Finally

, the figure for hydropower produced in

this

country still maintained, with 4%
