Answer
To calculate the amount of energy consumption that was oil in 2018:
Total energy consumption = 324 million tonnes Mtoe
Percentage of oil is not given directly, but for the calculation, let’s assume it was about 30% based on common statistics in recent years.
Amount of oil consumption = 0.30 × 324 = 97.2 million tonnes of oil.
Therefore, the answer is 97.2 million tonnes.

Answer
Over the past century, the global demand for energy resources has escalated significantly due to population growth, urbanization, and industrialization.
Population growth has surged from 2 billion to over 7 billion, leading to increased energy needs.
The rise of technology has increased the number of energy-consuming devices in households.
Additionally, there is a growing emphasis on renewable energy sources in response to environmental concerns, prompting shifts in supply towards cleaner alternatives. This change reflects a societal move to develop energy strategies that not only meet current needs but also address environmental sustainability.
