What is the principle of the law of thermodynamics that states "useful energy in, useful energy out"?
The principle you are referring to is the second law of thermodynamics, which states that in any energy conversion process, some energy is lost as waste heat, resulting in a decrease in the overall usefulness of the energy.
How does energy efficiency relate to the first and second law of thermodynamics?
By the first law of thermodynamics, energy is conserved - i.e. the sum of the useful work and the energy lost to heat will equal the energy you started with. The second law states that you will never get 100% energy efficiency.
Why is the conservation of energy an issue that people must deal with if the first law of thermodynamics states energy is not created or destroyed?
While energy is not created or destroyed according to the first law of thermodynamics, it can be converted from one form to another. The challenge lies in ensuring that energy remains usable and available in the desired form, without excessive losses or inefficiencies. Conservation efforts focus on reducing waste and maximizing the efficiency of energy conversion processes to minimize environmental impact and resource depletion.
How is the 1st law of thermodynamics related to the conservation of energy?
By the first law of thermodynamics, energy is conserved - i.e. the sum of the useful work and the energy lost to heat will equal the energy you started with. The second law states that you will never get 100% energy efficiency.
What law says energy cannot be converted without the loss of usable energy?
This concept is known as the second law of thermodynamics. It states that in any energy conversion process, some energy is wasted as heat and cannot be completely converted into useful work. This leads to an increase in disorder or entropy in a closed system.

Can energy be regenerated?
According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.

What is a 2nd law of energy?
You must be referring to the two Laws of Thermodynamics. Stated in terms of energy: 1. The First Law of Thermodynamics is the Law of Conservation of Energy, meaning that energy can not be created or destroyed. 2. However, useful energy is continuously being converted into unusable energy. This is irreversible. This is the Second Law of Thermodynamics.

How can red shift work without draining all of the energy in the universe?
The useful energy will be gone eventually, one way or another. As a result of the Second Law of Thermodynamics, it is unavoidable that we will eventually run out of useful energy.
What law of thermodynamics accounts for the other 75 units of energy?
The way that the question is worded it is impossible to be sure exactly what you are looking for, but as a reasonable guess, you are looking for what happens to energy that is not producing useful work. The second law of thermodynamics generally tells us that we can never get 100% efficiency, i.e. we can never convert all the energy we are using into useful work. Some of the energy will just go into increasing the entropy of the universe.
Which law of thermodynamics applies to percent of harvested energy?
The 2nd law of thermodynamics can yield predictions on the maximum efficiency of a process that seeks to extract useful energy. An example would be the Carnot cycle which gives the maximum percent of energy that can be harvested and turned into useful work as heat moves from a heat source to a heat sink.
How is the 1st law of thermodynamics related to the conservation of energy?
By the first law of thermodynamics, energy is conserved - i.e. the sum of the useful work and the energy lost to heat will equal the energy you started with. The second law states that you will never get 100% energy efficiency.
What states that when one from of energy is converted to another no energy is destroyed in the process?
That's the "Conservation of Energy"; also know as the "First Law of Thermodynamics". Please note that while TOTAL energy is conserved (doesn't change), in most or all processes that occur in practice, USEFUL energy is converted into UNUSABLE energy - often heat.
What law says energy cannot be converted without the loss of usable energy?
This concept is known as the second law of thermodynamics. It states that in any energy conversion process, some energy is wasted as heat and cannot be completely converted into useful work. This leads to an increase in disorder or entropy in a closed system.
Why is the amount of useful output energy always less than the input energy?
The reason the useful output energy is always less than the input energy is due to inefficiencies in the energy conversion process. Some energy is always lost as heat, sound, or other forms of energy during conversion, reducing the amount of energy available for useful work. This decrease in useful output energy is described by the concept of energy conservation and the second law of thermodynamics.
