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.

"Unavailable for doing work" is related to the Second Law of Thermodynamics.
Second Law of Thermodynamics
There are three laws of thermodynamics. The first law states that energy cannot be created or destroyed, only transformed. The second law states that heat naturally flows from hot to cold. The third law states that as temperature approaches absolute zero, the entropy of a perfect crystal approaches zero.
The Second Law of Thermodynamics.
No, the second law of thermodynamics allows for local decreases in entropy as long as there is a greater increase in the entropy of the surroundings, maintaining a net increase in total entropy. In the case of water freezing into ice, the decrease in entropy of the water molecules is accompanied by an increase in the entropy of the surroundings, such as the heat released to the environment.
There is no commonly accepted law by that name, as far as I know. Two important laws about energy are the First Law of Thermodynamics and the Second Law of Thermodynamics.
The fact that usable energy is always lost in an energy transfer is due to the second law of thermodynamics. This law states that entropy, or disorder, tends to increase over time in a closed system, leading to the loss of usable energy in the form of heat.
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.

Energy efficiency is guided by the first law of thermodynamics, ensuring that energy is conserved and not lost in a system. The second law of thermodynamics dictates that some energy will always be lost as heat in any process, so the goal of energy efficiency is to minimize this loss and maximize the useful work obtained from energy.

Second Law of Thermodynamics
First Law of Thermodynamics: Energy can be converted from one form to another, but cannot be created or destroyed.Second Law of Thermodynamics: The second law of thermodynamics states that for any process occurring in a closed system, the entropy increases for an irreversible system and remains constant for a reversible system, but never decreases.
The first law of thermodynamics is also known as the Law of Energy Conservation.
If you are suggesting a "perpetual motion" scenerio, it would violate the first or second laws of thermodynamics. Many inventors dream of perpetual motion machines, but they are an impossible dream according to the laws of thermodynamics. The second law of thermodynamics says that an engine or process of any type must always have an efficiency of less than 100%. A perpetual motion machine that uses a generator to power the motor that runs the generator requires both the generator and motor to operate with 100% efficiency. This type of perpetual motion machine does not violate the first law of thermodynamics, but violates the second law of thermodynamics. It is a perpetual motion machine of the second kind because it violates the second law of thermodynamics. Not even the cleverest engineer or inventor can build a perpetual motion machine because it would violate either the first or second law of thermodynamics, which are fundamental laws of physics.
