Energy principles
Basic Energy Principles
Energy is the driving force for the universe. Energy is a quantitative property of a system which may be kinetic, potential, or other in form. There are many different forms of energy. One form of energy can be transferred to another form. The laws of thermodynamics govern how and why energy is transferred. Before the different types of energy resources and their uses are discussed, it is important to understand a little about the basic laws of energy...
The Three Laws of Thermodynamics
There are three laws of thermodynamics. The first law of thermodynamics, also called conservation of energy, states that the total amount of energy in the universe is constant. This means that all of the energy has to end up somewhere, either in the original form or in a different from. We can use this knowledge to determine the amount of energy in a system, the amount lost as waste heat, and the efficiency of the system...
Seven energy principles

1. What Is Energy? We can think of energy as anything that can carry out an action or maintain a process. Without energy, everything comes to a halt... more

Some examples
Energy is defined as the ability to do work.

Work is defined as the transfer of energy....
