Energy balance can mean many things. In probably the most important sense it is just the First Law of thermodynamics rearranged slightly. "Energy can be neither created nor destroyed" becomes "Energy lost by one subsystem must be gained by another" or, yet again "If the net energy of a system remains constant, energy gained from outside must equal energy lost to the outside". Whilst this may lead to physical calculations, probably the most useful thing about the concept is that it alerts us to asking "where is the energy flowing" when we look at a system in detail. A previous answer, below, does this for global heat energy, though it pretty well ignores energy other than heat. For that reason it should alert us that we must look into whether there are any major energy flows other than heat. It is remarkable that there are not. The sun, for example does not balance its heat flow at all - 5 million tons of pure thermal energy are thrown out every second. But energy balance is restored by nuclear reactions which create about that much heat. This in turn should make us ask why the two processes are equal. The stability of stars kept astro-physicists busy for many decades in the twentieth century. Even so, the balance as described so far is not exact. Physically it must be precise overall, so there must be other energy flows. Some is accounted for by the fact the sun is getting bigger and hotter. The word "balance" is important. As with any other form of accounting, nothing has to balance line-by-line or even account by account, but you have made a mistake if the total - losses and gains over the entire system, debits and credits over all accounts - doesn't balance.
Since the earth is not getting warmer or colder, there must be a balance between insolation and long-wave radiation. the following happens:There is a gain of heat everywhere on Earth, except the poles where the surfaces reflect the heat (Albedo effect). A net deficit occurs here. There is a loss of heat throughout the atmosphere. When the heat gain and heat loss are balanced, the following pattern emerges: There is a surplus of heat in the tropics and a deficit of heat at the poles. To prevent the tropics from overheating, heat is transferred away from the tropics horizontally which results in a global circulation pattern. Heat is also transferred vertically by radiation, conductionand the release of latent heat.
Energy balance is important for maintaining a healthy weight and overall well-being. It refers to the relationship between the calories consumed through food and beverages and the calories expended through physical activity and metabolic processes. When energy intake matches energy expenditure, the body can achieve weight maintenance. An imbalance, whether excess or deficit, can lead to weight gain or weight loss, respectively.

How would you use the word energy balance in a sentence?
Energy balance refers to the relationship between the energy consumed through food and drinks and the energy expended through physical activity and metabolic processes. Maintaining a positive energy balance, where energy intake exceeds energy expenditure, can lead to weight gain, while a negative energy balance can result in weight loss.
What is the law of conservation of matter and energy mean?
The law of conservation of matter and energy states that matter and energy cannot be created or destroyed, only transformed from one form to another. This principle is a fundamental concept in physics and chemistry, emphasizing the importance of balance and conservation in physical processes.
What is global energy balance?
Global energy balance refers to the equilibrium between the amount of energy Earth receives from the sun and the amount of energy Earth radiates back into space. This balance is crucial for maintaining stable temperatures on our planet and sustaining life. Changes in this balance, such as an increase in greenhouse gases, can lead to climate change.
When the amount of energy received from the sun and the amount of energy returned to space are about equal it is called what?
When the amount of energy received from the sun and the amount of energy returned to space are about equal, it is called energy balance or radiative equilibrium. This balance helps maintain the Earth's overall temperature and climate.
When energy balance in the body is positive body mass decreases?
This statement is incorrect. When energy balance in the body is positive (caloric intake exceeds caloric expenditure), body mass increases. To decrease body mass, energy balance must be negative (caloric intake is less than caloric expenditure).

What is radiational balance?
Radiation balance is the balance between incoming energy and outgoing energy
What causes positive energy balance and what are the effects of positive energy balance?
Positive energy balance is when energy intake exceeds expenditure weight is gained
What is the balance between incoming and outgoing energy called?
The balance between incoming and outgoing energy is called radiation balance.
What is the importance of wind energy?

What is the importance of energy sources?
The importance is that energy is required to get just about anything done. In other words, we NEED energy.
