Energy Exists in Many Forms

Energy is the capacity of a physical system to perform work.

Energy exists in several forms such as heat, kinetic or mechanical

energy, light, potential energy, electrical, or other forms.

According to the law of conservation of energy, the total energy of

a system remains constant, though energy may transform into

another form. Two billiard balls colliding, for example, may come to

rest, with the resulting energy becoming sound and perhaps a bit

of heat at the point of collision.

In the context of physical sciences, several forms of energy have been defined.

These include

Thermal energy



Chemical energy



Electric energy



Radiant energy, the energy of electromagnetic radiation



Nuclear energy



Magnetic energy



These forms of energy may be divided into two main groups; kinetic

energy and potential energy. Other familiar types of energy are a varying mix of both

potential and kinetic energy.

Energy may be transformed between different forms at various efficiencies. Items that

transform between these forms are called Transducers.

It's good to know that energy does not disappear, it merely changes form. To receive

different forms of energy we use different energy sources and technologies. The

different forms of energy have different qualities and degrees of usefulness.

Primary energy sources are substances or processes with concentrations of energy at a

high enough potential to be feasibly encouraged to convert to lower energy forms under

human control for human benefit. Except for nuclear fuels, tidal energy and geothermal

energy, all terrestrial energy sources are from current solar insulation or from fossil

remains of plant and animal life that relied directly and indirectly upon sunlight,

respectively. And ultimately, solar energy itself is the result of the Sun's nuclear fusion.
