The Human Brain Generates About 20 watts of Electrical Power
The human brain, despite being a remarkable and complex organ, is surprisingly energy-efficient. On average, the brain generates around 20 watts of electrical power. This is roughly the amount of power needed to operate a dim light bulb. The energy is primarily used to support various cognitive functions, including thinking, memory, and decision-making. The brain’s efficiency in energy consumption is a testament to its evolutionary development and the necessity to perform intricate tasks while maintaining our body’s overall energy balance.
