The charts show the sources of electricity produced in 4 countries between 2003 and 2008. Summarise the information by selecting and reporting the main features, and make comparisons where relevant....

The given pie charts give information about the proportion of three different sources that were used to produce electricity in four countries, namely India, Sweden, Morocco and Vietnam, from the year 2003 to 2008.
Overall, Vietnam and Morocco did not use nuclear power for electricity production. It can also be seen that while fossil fuel was the largest source of electricity supply in Vietnam and India, it only occupied a relatively marginal proportion in the other two countries during the examined years.
In Vietnam, 56% of the total amount of electricity was from fossil fuel, and only 5%, however, was the figure for Morocco. The rest was produced from hydro power in both nations.
Between 2003 and 2008, fossil fuel contributed 82% to the entire quantity of electricity in India, which was also the highest among the four countries. Meanwhile, this source was responsible for the smallest proportion in Sweden, where hydro power constituted the biggest, at 52%. Nuclear power was used to generate 44% of the amount of electricity in Sweden while the figure for India was merely 3.5%.
