The pie charts compare the proportion of three different energy sources used to produce electricity in four countries in 2008.
Overall, India relied heavily on fossil fuel for power generation, while hydropower was the most popular source in Morocco. It is clear that all four countries utilized fossil fuel and hydropower, but Morocco and Vietnam did not apply nuclear power in producing electricity.
As can be seen from the pie charts, fossil fuel made up the largest proportion of total electricity manufactured in India, reaching as much as 82%. Following this country was Vietnam, where fossil fuel contributed to more than half of total energy consumption. By contrast, Sweden and Morocco had an extremely low rate of fossil fuel, at only 4% and 5% respectively.
Concerning Morocco, hydropower constituted 95% of the total power generation, against the lowest share 14% in India. Sweden and Vietnam used a similar proportion of hydropower, at 52% and 44% respectively. It is worth noting that only Sweden and India exploited nuclear power, but the proportion disparity was huge. The quantity of nuclear power in Sweden stood at 44%, while a mere 4% of this source was supplied for India.
