The line graph presents the proportion of four types of energy sources from 2025 until 2050. Overall, renewable energy will show a continuous rise over the 25 years, eventually becoming the leading energy source, notably overtaking oil as early as 2030; that position is predicted to hold for the remainder of the period. In contrast, the other three sources, namely oil, coal, and natural gas, will follow a downward trend.
Renewable energy started at around 25% in 2025. From there, it climbed steadily and consistently, without any fluctuation. By 2030, it will have intersected with oil at over 30%, and continue to rise at a similar pace every five years. By 2050, it will have reached around 55%, which means its share of global energy consumption will have more than doubled over 25 years.
In contrast, the three remaining energy sources will decline over the period, even though not at the same rate. Oil will fall gradually from 35% to 20% throughout the period. On the other hand, coal will experience the sharpest decrease of all, plunging from 20% in 2025 to almost 0% by 2050, which will be lower than natural gas. Natural gas will remain comparatively stable around 15-20% for most of the period and will end slightly lower than where it started.
In conclusion, renewable energy is predicted to dominate global energy consumption by 2050, having overtaken all three sources during the period, while oil, coal, and natural gas will continue their gradual decline, with coal experiencing the most dramatic fall of the three.
