Historically, fossil fuels have dominated global energy production, but a major shift is underway towards clean energy sources. Today, fossil fuels still make up the majority of overall primary energy, though clean power is rapidly overtaking fossil fuels in global *electricity* generation.

Per gram, lipids contain over twice the energy of carbohydrates, with 9 calories per gram compared to carbs' 4 calories. So, are carbs or lipids a better source of energy for your body? The answer depends entirely on the intensity of the activity and your body's metabolic demands.

According to the Energy Institute's 2024 Statistical Review, fossil fuels accounted for over 81% of global primary energy consumption in 2023. This stark figure illustrates that despite a rise in renewables, the world still heavily relies on traditional sources for its power needs and provides the context for answering where do we mainly get our energy from.

Globally, approximately 80% of the primary energy consumed still originates from fossil fuels, despite rapid growth in renewables. Understanding **where does most of our energy come from** requires distinguishing between primary energy and electricity generation sources.
