The conservation of energy is a principal matter in the study of energy.

Conserving energy in my mind is the wrong vocabulary.  I believe we should be told to use energy wisely with caution and avoid using more than necessary.  As Mr. Comosy uses as an example in class, don’t cut your butter with a chain saw.  When we say, “conserve energy,” we are stating that the expensive processes of converting energy are meaningful.  Entropy is the useless energy that has dispersed from conversion.

Conservation of energy is the performing of “irreversible processes.”  For example, when you drop an egg on the ground it breaks, but dropping a broken egg does not make it whole.  This established the flow of direction in entropy.  Every time you do anything entropy increases.  This leads to the second law of thermodynamics, which states that the entropy of the universe never decreases, but increases whenever possible.  

As the entropy increases in our universe, we must learn to make difficult decisions to protect our world.  We might have to change our lifestyle to effect difficult decisions in the future.  As I review Galileo’s balls on the elevated platforms, for the second time, I come to the conclusion that they are not totally realistic.  In order for the potential energy due to gravity to transform to kinetic energy, friction must take a part in causing some of the energy to become lost or useless.  This is entropy.
