What is Energy?
ENERGEIA
ll the universe is made up of two things: matter and
energy. Mass refers to anything that takes up space,
while energy is the ability to move or incite a change
in matter. In other words, energy refers to the
capacity of something to cause things to happen.
There are many forms of energy, including chemical,
thermal or heat, electrical, electrochemical,
electromagnetic or light, sound, nuclear, and
hydrogen energy.

kind of action. A linguistic analysis shows that, by

Interestingly in older Christian writings it used in
describing God, as God is referred to as energy in
constant action.

irst, energy is "conserved." According to the First
Law of Thermodynamics, energy cannot be created
or destroyed; rather, it can only be transferred from
one object to another or from one object to a system
through the interaction of forces. Most of the
principles from which
modern energy
industries operate are
founded upon this
concept.
History of Energy

econd, energy has multiple forms, and it can be
converted from one form to another. In its most basic
sense, energy can be classified into kinetic, potential,
thermal (heat), chemical, electromagnetic, and
nuclear energy, to name a few. Of these, the two
most basic forms are kinetic energy and potential
energy.

or thousands of years, we did not have a scientific
concept of energy, more so of its utilization and
conversion. The scientific concepts related to energy
only came about during the modern era, when
scientists began to find objective and concrete
explanations for these phenomena. In considering
these Laws of Thermodynamics, it has been
relatively easier for us to understand why so much
progress occurred in just the last 200 years.

pecifically, without newer forms of energy and the
surplus energy they have created, we would still be
busy producing everything manually, hence, no

ergy can shift between forms, but it is never destroyed or

A car transforms the potential energy trapped in gasoline into
various types of energy. Most of the energy is actually lost to
heat.
Power plants transform one form of energy into another form,
electricity. Coal and natural gas plants use the chemical
potential energy trapped in fossil fuels. Nuclear power plants
change the nuclear potential energy of uranium or plutonium
into electricity too. These transformations are hardly perfect. An
efficient fossil fuel power plant loses more than half of energy
to other forms than electricity, such as heat, light, and sound.

onventional or Non-Renewable Sources
This category refers to finite resources that will
eventually run out and be exhausted. This type of
energy cannot be renewed or replaced once they run
out. They are also called conventional sources
because these are the ones we have been
depending on since the beginning of civilization. The
main examples of non-renewable and conventional
sources of energy include fossil fuels (e.g., wood,
coal, petroleum), nuclear power, and crude oil.

on-Conventional or Renewable Sources
This category refers to sources that are generated
from natural resources but are renewable and can be
easily replaced because they are naturally
replenished at the same rate that they are being
used. Hence, they are often desirable because they
are cleaner, cheaper, and easier to harness. Some
examples of renewable sources include wind power,
tidal power, geothermal power (i.e., energy from heat
generated deep underground), solar power, hydroelectric power, biomass, and ocean thermal power.
