Band 4+: The pie chart below compare the proportion of energy capacity in gigawatts (GW) in 2012 with the predictions for 2030. Summaries the information by selecting and reporting the main features, and make comparison where relevant.

The pie charts demonstrate the percentage of gigawatts capacity in 2015,while having predictions for the 2040 year.

Overall,it is clear that fossil fuels usage was the highest rate compared to other energies in both given years.However the lowest contribution was held by nuclear energy on the given data.

To begin with,in 2015 The figure for fossil fuels total proportion was the 64 percent,also it showed a remark increase in the fature years with 44 percent.By contrast,it increase rapidly to compared other energy usages in both years.The wind power was the second most used energy source due to its total was 23 in 2015,but in the 2040 it decrease slightly to 3 percent.

The most important event occur in three energy recources with almost similar rates which is the Solar,Nuclear and Other renewables.The total percentage of Other renewables and nuclear were almost similar 6 percent and 5 percent,but the lowest was solar energy by only two percent.Interestly, In predictions of 2024,it will increase to 2 to 18 percent.Two lowest energy sources increase noticeably in 2040,expect nuclear energy due to its expperinced an slight decrease with only 1 percent.
