• Unit : joul
Thermal energy
• Thermal energy is the
energy portion of a
system that increases
with its temperature.
• thermal energy" is a term
used to describe the
energy content of a
system related to heating
effects, e.g. temperature
increase or decrease
Gravitational energy
• energy associated
with the gravitational
field
Geothermal Energy
• Energy generated by
heat stored beneath
the Earth's surface or
the collection of
absorbed heat in the
atmosphere and
oceans
Elastic Energy
• The elastic energy is
the energy which
causes or is released
by the elastic
distortion of a solid or
a fluid.
• Elastic energy is
internal energy that
can be converted into
mechanical energy
Sound Energy
• Sound is vibration
transmitted through a
solid, liquid, or gas;
particularly, sound
means those
vibrations composed
of frequencies
Chemical Energy
• Chemical energy is the
energy due to
associations of atoms in
molecules and various
other kinds of aggregates
of matter. It may be
defined as a work done
by electric forces during
re-arrangement of electric
charges, electrons and
protons, in the process of
aggregation
Nuclear Energy
• Nuclear Energy is
energy due to the
splitting (fission) of
the nuclei of atoms.
Nuclear Energy
• Fusion, two atomic
nuclei fuse together to
form a heavier
nucleus
• Suitable areas for wind farms are often near the coast,
where land is expensive.
• Can be noisy.
