The diagram provided are four pie charts that provide information about three main electricity sources produced in four countries including India, Sweden, Morocco and Vietnam between 2003 and 2008.
The sources listed above include fossil fuel, hydropower and nuclear power. Interestingly, it shows that India and Sweden both utilise three different sources to generate electricity whereas Morocco and Vietnam only use two sources, which are fossil fuel and hydropower to supply electricity in their countries.
First and foremost, fossil fuel is the main source of the electricity in both India and Vietnam, representing 82% and 56% respectively despite its least usage with less than 5% for both Morocco and Sweden. On the other hand, Hydropower is widely and predominantly used in all four countries, with largest usage in Morocco which is 96%, second highest in Sweden which is 52%, followed by Vietnam with 44% and India with 15%.
In overall, nuclear power is not a common source especially for Morocco and Vietnam between 2003 and 2008, highlighting fossil fuel and hydropower as the main contributors to electricity among countries.
