The world’s energy consumption has a fascinating story to tell, especially when we focus on coal. In 2019, global coal usage underwent slight fluctuations but remained a major player in the energy scene, with around 7,000 TWh typically attributed to coal that year. Keep in mind that the rise of renewable sources has started putting pressure on coal usage! When assessing energy usage, it’s easy to overlook the impact of policy changes and technological advancements on consumption trends. For instance, many countries have introduced incentives to boost renewables, which may reduce coal dependence over time. So, while you might be estimating figures based on past trends, keep an eye on the future as the energy landscape evolves!
