Quick Summary

Energy consumption refers to the use of energy by humans and systems. In the United States, fossil fuels (oil, natural gas, and coal) accounted for 82.3% of energy consumption in 2025, while renewable energies made up 9.1%, and nuclear power 8.5%. Renewable energy sources include solar, wind, hydroelectric, geothermal, and biomass.12

Beyond societal energy use, the human body also consumes energy for basic metabolic processes, digestion, and physical activity. The basal metabolic rate (BMR) is the energy needed to support life at rest. Energy expenditure can be measured in kilocalories and varies significantly based on activity levels.3

Buildings can also be designed for zero net energy consumption and zero carbon emissions, known as zero-energy buildings (ZEBs). These buildings often generate their own energy on-site using technologies like solar panels and wind turbines. Even digital technologies like Bitcoin consume significant energy, with its usage being a subject of debate regarding its environmental impact.45

Despite its large hydrocarbon reserves, rapidly increasing domestic demand driven by population growth and industrialization in the first decade of the 21st century forced the emirates to import natural gas and to draw upon petroleum reserves at a fraction of the export price.
