The scientific meaning of energy conservation is the transformation of energy from one form to the other while keeping the total energy of a system constant. The total energy in a system does not change and it can neither be created nor destroyed. However, people have a different meaning to energy consumption. They view energy consumption as the practice of reducing the amount of energy used where they seek to economize energy use. People view energy conservation as a reduction in the financial expenses incurred when using energy. People have the notion that energy can be reduced by adapting eco friendly ways that reduces the effects of too much consumption of energy on the environment. People came up with their own definition of energy conservation because of the effects of global warming with allegations that energy use in homes and industries were causing massive negative effects to the environment. They have come up with their own definition of conservation of energy claiming that one can reduce the use of energy in their homes and industries by adapting to alternative sources of power, (Thiede, 2012).

Entropy and efficiency are closely linked because entropy increases with the increase in energy use. This means that the entropy of a system increases with the flow of heat or temperature from one system, o the other. The aspect of entropy is not reversible as seen when tea that was being stirred becomes cold and stops swirling. The heat lost cannot come back after a while. This is also evident when glass is broken. Therefore, efficiency is required for energy conservation because energy lost as it flows from one system to the other cannot be recovered in any way. The use of energy in systems requires a high level of efficiency because two systems put together will transfer energy from one to the other and at the end one of the systems will have more energy while the one other one remains with less energy, (Thiede, 2012). The system gaining the energy will increase its entropy while the one losing will loss entropy. A person seeking to maximize energy transfer from one system to the other will have to consider the energy lost as energy moves from a system with small b to a system with large b. The transfer of temperature does not follow this principle as it flows from a system with high temperatures to that with lower temperatures, (Sengupta, California, 1994). The thermal aspect of entropy is therefore useful in determining the effectiveness of energy and it usefulness to the system. The supply of energy at high temperatures, but at low entropy levels is more efficient and useful in conserving energy as compared to low temperatures and high entropy. The energy in the situation described above is more effective that the same energy used in room temperatures. The importance of efficiency in regards to entropy is evident in the increasing entropy of the universe and the decrease in the effectiveness of the total energy.

One cannot leave the door of a refrigerator open on a hot day in the hope that it will decrease the heat in the room. This is because there is no cold but it is the absence of heat in a substance. The refrigerator operates by taking the heat of hot substances and depositing the heat back into the room. This is why if one leaves the door of a refrigerator open he or she is making it hard for it to remove the heat from the things inside it and the heat in the room. The heat removed will be deposited back into the room making it even warmer. The air conditioner on the other hand makes the room cool because it has fans on both sides, which make the air in the room move around. The movement of air around us makes the sweat in the body feel cooler as compared to stand still air.

Deterministic chaos can be used in different ways and one of them is in the electronic communications where it can decode electronic information. This works when signals at the sending stations create chaotic messages that is fed into a stable communication system that will produce a chaotic output signal at the receiving station. The chaotic signal mixed with the encoded message will reach the receiving station, which will feed the original chaotic coded message into the stable communication system and remove the chaotic signal. The receiving station then remains with the original message. The motion of a satellite as it goes round the earth is another example, (Parker, Walker, 2010).The velocity and Newton’s mechanisms make it possible for scientists to calculate and predict the position of the satellite at a particular time.

The systems that exhibit chaos and random motions are fluidized beds applies the theory of Turbulent fluid flow because no one can predict the behavior of a turbulence because it can be so erratic when it changes that it makes it difficult to predict its course. This is because of its sensitivity to change in its original state.

The high security teleprinter is an example of a system that utilizes random properties. This teleprinter cipher machine has high security radio that enables communication in secrecy. It uses 32 symbols in its alphabet and has five channels streaming bits represented as zero, one, or no hole. Messages had obscuring characters that world cancel out at the receiving end where the original message is teleprinted. The characters were purely random to prevent breaking the chain common in the onetime pad system.

The examples are similar because at some point in time they depend on the changes in the surroundings to predict its outcome. This is because the states of the systems depend on energy changes and how sensitive they are to these changes. The difference comes in with how its sensitivity affects its outcome. The fluidized beds are highly sensitive to changes in turbulence while the satellite and the electronic communications are less affected by sensitivity.
