Four Source of Energy: Chemical, Solar, Mechanical, and Nuclear
Energy is used in every aspect of our lives, from power for transportation, to heat and
light in dwelling and working areas, to the manufacture of good of all kinds. The
development of science and civilization is closely linked to the availability and
development of energy in useful forms. In this paper I am going to show four extremely
vital forms of energy that we humans use everyday, and without which we could not enjoy
the luxuries of life; like watching T.V., playing on the computer, and tracking the

The first type of vitally important energy is Chemical. It utilizes the energy release
from chemical reaction. The energy is both release and absorbed by the elements involve in
a chemical reaction, but no lose occur in the molecular weight of the elements. Even
thought this is true, the physical properties may change. Take for instance, the
decomposition of water. In its molecules, each of which consist of one atom of oxygen and
two of hydrogen, are broken down; the hydrogen atoms combine in pairs, and the oxygen
atoms form oxygen molecules. The two new molecules now have two different properties from
the water molecules they came from. Water, for example, does not burn nor does it support
combustions, but the new hydrogen molecule is now flammable and the oxygen is combustion
supportive, both of which can be used to obtain useful forms of energy.

The reactions, just like the one mentioned above, can be classified by the characteristics
of the particular reaction. As anyone could observe we, the people of this world have many
different forms of reactions to obtain the energy we desire. This chemical energy is
pretty the base of all other forms of energy, or at least a big part of them.

We can use the reaction from nuclear fusion or fission to obtain energy. We can use the
steam from water to get energy. There are ways in which use the elements and the
properties of their reaction to obtain energy.

A type of energy that work is another form of chemical energy, but deserves its own
individual respect, is the above-mentioned nuclear energy. With the development of nuclear
energy in the early 20th century came available another incredibly great source of energy.

It uses the heat from the nuclear energy and converts it into electricity. The nuclear is
stored in the nucleus of an atom and is released though fission, fusion, or radioactivity.
In these processes a small amount of mass is converted to energy according to the
relationship E= mc^2, where E is energy, m is mass, and c is the speed of light. The late
physicist Albert Einstein discovered this relationship between energy and mass.

In this case the thermo energy, from the nuclear reaction, is the key to deriving the
electrical energy needed. The heat from the nuclear reactor, the thing which prevent the
reaction from becoming a chain reaction, can be used to produce steam. The steam can then
