usable energy changes, while total energy does not
The idea here is that part of the original energy is wasted - converted to an unusable type of energy.
No. It tends to decrease.
In any transfer of energy or conversion of energy from one form to another, the total amount of energy does not change. The total amount of usable energy, however, always decreases.
According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.
Not at all. The First Law states that energy is conserved - you can't create energy out of nothing, or make it disappear. The Second Law distinguishes usable from unusable energy, and states that the amount of unusable energy will increase over time - but the total (usable plus unusable energy) will still remain constant.Not at all.

neutral fats, or triglycerides, represent the body's most abundant and concentrated source of usable energy.
The usable energy from the sun is typically measured in kilowatt-hours (kWh) or watts (W) for solar panels and systems. This helps to quantify the amount of energy that can be harnessed from the sun for various applications, such as generating electricity or heating water.
Usable energy is called kinetic energy, which is the energy possessed by an object due to its motion. It can be harnessed to perform work or activities.
Any freshwater on Earth is usable
Usable energy refers to the energy that can be effectively converted and utilized for various purposes, while total energy represents the sum of all energy present within a system, including both usable and unusable forms. Usable energy can be harnessed to perform work, whereas total energy includes potential energy that may not be readily available for use.
Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe. The wasted energy is related to entropy - one way to express the Second Law of Thermodynamics is to say that there are irreversible processes (in terms of energy), another is that "entropy increases". However, entropy is not energy; it is not measured in Joule, but in Joule/Kelvin. In any case, you might say that when energy is wasted, entropy increases.Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe.
