Basal Metabolism (BMR)
Weight is determined by the balance between energy intake and energy expenditure. When energy intake exceeds expenditure, the excess energy is stored as fat, leading to weight gain. On the other hand, if energy expenditure exceeds intake, the body uses stored energy reserves, resulting in weight loss. Maintaining a balance between energy intake and expenditure is crucial for weight management.
Net energy expenditure is more important because it represents the energy that is actually available for the body to use after accounting for energy lost as heat during metabolism. Gross energy expenditure includes all energy expended, both useful and wasted, providing a less accurate picture of the body's true energy needs. Focusing on net energy expenditure helps in understanding how much energy is actually available to fuel physiological processes and activities.
Approximately 23% of the US energy supply comes from coal.
Energy expenditure is that amount of calories that someone uses in one day by exercising or doing everyday tasks.

The 98 percent would be light energy, or electromagnetic radiation, and the other 2 percent would be converted into thermal energy, or heat.
Approximately 23% of electricity in the US is produced by coal energy.
Approximately 10% of energy is transferred from one trophic level to the next in an ecosystem. This is due to energy loss through metabolic processes, heat production, and inefficiency in energy transfer.
