What Is Energy

Energy is neither created nor destroyed. This is called the principle of Conservation of Energy. In other words, the amount of energy in the universe always remains the same. And when we use energy, like burning wood to generate light and heat, we don't use it up; we simply transform it from one form of potential energy (fuel) into other forms of kinetic energy (heat and light).

Almost all energy transformations involve the production of heat, which is considered the lowest form of energy, because it quickly dissipates into the surroundings and is normally unavailable for further use. So, although the total amount of energy remains the same, the amount of "useable" energy constantly decreases. However, don't worry too much about the decrease of useable energy; our Sun is scheduled to produce solar energy for many years to come, so taking this course will not be a waste of your time (or energy).
