The line graph illustrates the consumption of four main energy sources over a 10-year period from 2010 to 2020. Overall, while the demand for renewables and natural gas increased significantly, the use of coal and oil declined moderately. Notably, renewables saw the most substantial growth, ultimately surpassing all other sources by the final year.
Focusing on the rising sources first, the consumption of natural gas and renewables exhibited a consistent upward trend. Renewable energy started at just below 10 exajoules and surged dramatically to over 25 exajoules by 2016. This was followed by another sharp increase of 30 exajoules, reaching a staggering 55 exajoules in 2020, making it the most consumed energy source. In comparison, natural gas usage rose steadily from 30 to 45 exajoules by 2016, after which growth slowed slightly, finishing at 52 exajoules. Despite both sources increasing, renewables experienced the sharpest surge, overtaking all other energy types by the end of the period.
In contrast, coal and oil usage followed a downward trajectory. Coal consumption fell from 50 exajoules to just under 30, while oil demand declined more gradually, dropping from 45 to 35 exajoules. Despite this overall decrease, coal remained the second-most consumed energy source, whereas oil still ranked as the third most utilized in 2020.
In summary, while the reliance on fossil fuels weakened, renewable energy became the dominant source, reflecting a broader shift toward cleaner energy alternatives.
