The line graph shows data about how much enegry was consumed by six different sources of fuel in country A from 2000 to 2020, and prodection until 2050 measuring Quadrillion Units.
Overall, almost every type of fuel was fluctuated over the period. Nevertheless, petrol and oil sector always showed dominancy while Nuclear, Solar/Wind, and Hydropower were exactly the mkst loest usages.
Turning to the details, the figure for the Petrol and oil started by 35 in 2000 and reached the peak of aproximately 41 Quadrillion Units in 2020 and expected increase to 47 until 2050. The coal consumption in first 15 years showed from 16 to 24 Unit which was increased significantly, it projected 33 quadrillion unit in the future. In comparison with Natural gas and coal, Natural gas was fluctuated in both history and projection, despite it expected reaching the peak of 25 in 2035.
The next three types of fuel (Nuclear, Solar/Wind, and Hydropower) displayed almost the same index at the beginning of period about 4 units, but over time nuclear was forecast lead to 7 quadrillion unit in 2025, while others will not expect increasing as it. However in the future Solar and wind will predict rise to 6 while Hydropower will show steadly figure in the projection.
