Fossil fuels dominate world's energy supply while renewable sources rely on the Sun. Renewable energy faces challenges despite its importance.
Fossil fuels supply the majority of the world's energy, accounting for 86% of global energy consumption in 2016. This includes coal, oil, and natural gas derived from ancient organic matter.
The Sun is the ultimate source of energy for various renewable sources, such as solar power, wind power, and hydropower, by driving processes like photosynthesis, wind generation, and the water cycle.
While renewable energy is crucial for sustainability, fossil fuels still dominate global energy production due to challenges in storage, grid integration, and transportation.
