The line graph gives information about the usage levels of energy consumption based on different types of fuel sources in one country between 2000 and 2020, with predictions for the years 2030 and 2050. Overall, total energy consumption of petrol and oil increased. This was followed by coal and natural gas. In contrast, other types of energy showed different trends.
In terms of petrol and oil, this category had the highest level of energy consumption, with 35 quadrillion units in 2000. This number grew to around 40 quadrillion units by the year 2030, despite some fluctuations. It is expected that this category of fossil fuels will remain unchanged during the subsequent 20 years and will have reached its peak at almost 50 quadrillion units in 2050.
Regarding energy usage of natural gas and coal, the former had 20 quadrillion units, whereas the latter had roughly 15 quadrillion units. The energy usage of coal was approximately 25 quadrillion units in 2030, despite some fluctuations. It is anticipated that the energy consumption of coal will grow steadily and will have reached its peak at roughly 35 quadrillion units by 2050. The energy consumption of natural gas showed an upward trend reaching approximately 25 quadrillion units in 2030. The energy consumption of natural gas is predicted to remain relatively unchanged, despite some fluctuations, during subsequent 20 years.
In terms of nuclear, solar, and hydropower, all three started at a similar level, with around four quadrillion units. Wind and solar are predicted to mirror nuclear’s rising trend, increasing to around six quadrillion units, while hydropower followed a downward trend and reached its lowest level with three quadrillion units in 2050.
