Band 6+: 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 given pie charts illustrate the percentage of producing five non-renewable powers in one country in 1983 and 2003.

Overall, five out five surveyed categories witnessed an upward trend, except for oil and coal energy production, while hydropower remained unchanged. Additionally, the figure for oil was the highest category during two different years.

According to the quantity of power produced in 1983. At nearly half, the fire for oil manufacturer took the lead, followed by 23% and 20% of the percentage of manufacturing coal and nuclear power respectively. At the same time, the lowest non-renewable energy was true for natural gas and hydropower at 11% and 4%.

After a 20-year period, the figure of energy manufactured in a country experienced minimal change. Standing at 38%, the quantity of oil manufactured was higher approximately twice than nuclear power and natural gas producing. Similarly, the coal producing hit the low at 13%, while hydropower energy stable unchaged.
