Safeopedia explains High-Quality Energy
There are several types of energy, which fall into two main categories. The first is kinetic energy, which is matter that has energy due to it's mass and speed. The second is potential energy, which is stored energy that has the potential to do work. Different kinds of energy within these include chemical energy, heat energy, electrical energy etc.. Electrical energy is generally considered high quality due to its efficiency when it is transformed to other forms of energy.
